[00:01:08] <rene-dev-> PCW: ok, thanks for your help, I want to be compatible with the stock mesa firmware, so I find some way to get the timing right.
[00:02:02] <PCW> Thanks for that, my desire to poke at that firmware is not high :-)
[00:04:27] <rene-dev-> no problem, I would have done it myself, I did some fpga stuff already... so not adjustable via the csr?
[00:05:00] <PCW> At one time we considered measuring the worst case return time, and that might have fixed your issue
[00:05:01] <andypugh> PCW: Actually, the already-existing 5i24_16_RMSVSS6_8_72.BIT file looks perfect..
[00:05:01] <PCW> (This would probably require adding random delays so we get good sampling statistics)
[00:05:20] <PCW> well Jolly Good!
[00:06:06] <andypugh> I assume 7i84 just uses GPIO and the channels just need setting up with the right directions?
[00:06:06] <PCW> Unfortunately its not adjustable via CSR since the fudge number is a constant and not a variable)
[00:06:09] <rene-dev-> but it would be helpful to know what causes Communication error and Extra character, is that timeout related as well? I could not see where they come from by looking at the sources...
[00:06:40] <PCW> 7I84 has fixed inputs and outputs (32 inputs 16 outputs)
[00:07:10] <andypugh> Yes, so I need to set the GPIO directions to suit?
[00:07:27] <andypugh> Or do some bitfiles control the direction?
[00:07:28] <PCW> yes extra char errors could be data received after we timed out, and cleared the RX FIFO
[00:07:53] <rene-dev-> ah, ok
[00:08:11] <PCW> The 7I84 has no direction options (only inputs and outputs)
[00:08:15] <andypugh> I am being daft. 7i84 is smart-serial
[00:08:25] <PCW> (yeah no GPIO)
[00:09:08] <andypugh> I was assuming I had bought 3 cards to suit the 3 headers on the 6i24
[00:10:06] <PCW> the 7I90 can be used as a 72 TTL level I/O sserial card but its config just uses open drain so there's no access to direction
[00:10:08] <andypugh> But, in fact, I will have a spare header. Hmm, and I do have a spare 7i39….

[00:33:09] <andypugh> Interesting, the 6i24 has 4 user-LEDS but Hostmot2 only makes pins for two of them.
[00:33:41] <andypugh> (Not that I have ever found a huge amount of use for them)

[00:36:36] <Wolf_> yeah, well I didnt know it needed this much work, I usually fill the role of clueless enduser well tho :)
[00:36:50] <ssi> are you gonna be able to assemble these things?
[00:36:56] <Tom_itx> it's not that difficult really
[00:37:06] <Wolf_> yeah, I can do hardware no problem
[00:37:11] <rene-dev-> the stmbl?
[00:37:21] <ssi> Wolf_: you're comfortable with 603 and 0.5mm pitch qfps?
[00:37:29] <Wolf_> yeah

[01:17:03] <Jymmm> zeeshan|2: ?
[01:18:04] <Valen> Jymmm: they are multi mode, and push on push off ;->
[01:18:15] <Valen> short press/release turns it on in high power

[01:21:00] <Tom_itx> Jymmm, you don't have one like this:
http://tom-itx.no-ip.biz:81/~webpage/scope/led_harness_on.jpg
[01:21:39] <andypugh> zeeshan|2: The first one has no apparent data for 80C
[01:21:54] <Jymmm> Tom_itx: You're right, mine has 96 leds
[01:21:55] <zeeshan|2> yes
[01:21:57] <zeeshan|2> its pretty much failed
[01:22:00] <andypugh> Ah, no, wait, I see it now
[01:22:03] <zeeshan|2> at 0.2 strain
[01:22:04] <zeeshan|2> early
[01:22:12] <zeeshan|2> ignore some of those circles
[01:22:17] <zeeshan|2> i didnt clean up the after fracture data , sorry
[01:22:58] <zeeshan|2> im thinking the second one looks like a typical polymer tensile test curve
[01:23:00] <Tom_itx> Jymmm the fenix is working nicely for what i got it for
[01:23:01] <andypugh> I never did polymers you know, they hard hardly been invented when I was a lad :-)
[01:23:13] <zeeshan|2> but the first one looks like something that is very linear in the beginning
[01:23:20] <zeeshan|2> but then hardens a bit
[01:23:26] <zeeshan|2> hahaha
[01:23:37] <zeeshan|2> i hate polymers. :[
[01:23:41] <Jymmm> Tom_itx: Cool, just remember to semi-unscrew the battery cap when you store/not using it
[01:23:48] <zeeshan|2> im just happy my apparatus is giving some REAL results now
[01:23:52] <zeeshan|2> that show some REAL trends!!
[01:23:56] <andypugh> Yes, the first one is somewhat strain-harding, the second is wierd.

[01:24:54] <zeeshan|2> im really hoping its a linear combination of the two curves
[01:25:15] <Jymmm> Valen: Are those to be a trendy cool wood keychain flashlight thingy?

[01:25:32] <zeeshan|2> they were glued together

[03:03:22] <Jymmm> why red?
[03:04:24] <renesis> is it for growing stuff?

[03:06:13] <renesis> anyway, high quality is pretty much anything from mouser/digikey, and red isnt uncommon in high power LEDs, chips and star mounted
[03:08:22] <renesis> damn, still spendy

[07:10:55] <renesis> do you know how to do thermal maths for electronic parts?
[07:11:17] <renesis> you need to figure out your ambient temp and max operational part temp
[07:14:00] <renesis> that delta is what you use for the C/W calculation, you take the Rth for junction to case, add that to the Rth for the heatsink, and use that summed C/W for temp rise
[07:15:00] <renesis> for example, you have a 30W dissipation LED with a Rth juunction to case of 0.5 C/W, ambient of 25C, max operational temp of 85C
[07:15:45] <renesis> so you delta is 60C, divided by 30W is 2 C/W
[07:16:22] <renesis> subtract your LED's Rth of 0.5, and the remaining 1.5 C/W is the maximum Rth of your heatsink
[07:17:10] <renesis> put the Rth into the heatsink calculator, and itll have suggestions of extrusion profile dimensions and lengths
[07:17:26] <renesis> use those dimensions to figure out what you need to buy on ebay
[07:17:41] <renesis> or scavenge
[07:19:15] <renesis> if you have a chassis mount heatsink resistor with a low Rth, you can use that to test a heatsinks Rth
[07:19:16] <Valen> its going to be run connected to an Al heatsink for periods of about .1 second per few seconds
[07:19:31] <Valen> thermal considerations are not high on my list at the moment ;->
[07:19:58] <renesis> measure heatsink ambient temp, mount resistor, burn a watt in it, wait until heatsink temp stabilizes, and the temp rise is your C/W
[07:20:44] <renesis> you can usually use average power dissipation for heatsink calcs, thermal stuff is pretty slow
[07:21:13] <Valen> yeah, I'm not really concerned at all, its going to effectivley be liquid cooled
[07:21:25] <Valen> and I'm happy to modulate duty cycle to limit temperature
[07:22:31] <renesis> big hammer solutions are best for prototype stuff, heh
[07:23:00] <renesis> and yeah if youre not exceeding LED spec and youre doing temp feedback, you can get away with pretty tiny heatsink
[07:23:35] <Valen> but yeah finding the LED is the trick
[07:23:42] <renesis> also remember ambient temps do not mean room ambient temps, its the local ambient temp
[07:24:05] <renesis> like if you have two resistors right next to each other, the operation temp of one is pretty much the ambient temp of the other
[07:24:18] <Valen> I do get paid to design electronics yaknow ;->
[07:24:21] <Valen> http://www.ebay.com.au/itm/LOTS-10W-20W-30W-50W-100W-RGB-SMD-Bright-High-Power-LED-Chips-Flood-Light-Bulb-/191533898420?
[07:24:26] <renesis> yeah i dunno
[07:24:47] <Valen> I got one of those in red but I'm pretty sure its just a bunch of white LED's with red crap poured over it
[07:24:59] <renesis> heh
[07:25:48] <renesis> yeah they all got the same Vf ranges
[07:26:17] <Valen> I figured they added more led's to get the wattage up and use the same driver
[07:26:32] <Valen> I feel I overestimated them :-<
[07:27:49] <Valen> I could spend $100 on 20 odd of these,
http://au.element14.com/osram/lrw5sn/led-smd-4-6w-red/dp/1244088
[07:28:07] <Valen> which is the cheapest E14 has for high output red LED's
[07:29:09] <renesis> yeah was kinda surprised the price hasnt dropped very much
[07:29:47] <Valen> I think all the demand is in white
[07:30:03] <Valen> E14 is also super expensive
[07:30:21] <Valen> on the plus side a string of 20 of those is drivable from my lab supply
[07:31:02] <renesis> id trust the osram part way more than superchina high power LED
[07:31:22] <renesis> the osram part has a datasheet, and a C/W spec
[07:32:40] <Valen> yeah, its also 10x the price though and I still need to make a PCB and driver ;->
[07:33:15] <renesis> ya =\

[15:11:06] <malcom2073_> yeah?
[15:11:14] <SpeedEvil> malcom2073_: If you actually seal the garage 100%, then you can dehumidify it.
[15:11:31] <SpeedEvil> Otherwise, it's not going to do much
[15:11:39] <malcom2073_> "do much" is this a 1%, or a 50% thing?
[15:11:56] <SpeedEvil> I assume the walls and ceiling is not clear?
[15:12:03] <SpeedEvil> That is - you can't put insulation on it?

[15:16:02] <malcom2073_> Ho?
[15:16:07] <Jymmm> backho
[15:16:12] <malcom2073_> It's aboveground
[15:16:15] <malcom2073_> well, half of it is
[15:16:54] <malcom2073_> About half of one wall is underground, one is attached to the basement of the house, one is above ground, and one is garage doors
[15:17:30] <Jymmm> malcom2073_:

[15:17:51] <malcom2073_> That stops wind driven rain, I'm not getting leaking
[15:18:05] <malcom2073_> And mostly from the floor/ceiling
[15:18:23] <malcom2073_> That's nifty though
[15:18:53] <Jymmm> Well, suck vid, but you need the masonary waterproof paint
[15:19:04] <Jymmm> the thick shit =)
[15:19:52] <malcom2073_> I'm finding conflicting information on if I can waterproof paint/epoxy the inside of a concrete slab
[15:20:18] <MattyMatt> of course you can
[15:20:31] <malcom2073_> MattyMatt: That's what some people say, indeed
[15:20:37] <MattyMatt> if you buy Our Product™
[15:20:41] <malcom2073_> heh
[15:21:10] <MattyMatt> floor leveling compound is epoxy
[15:21:18] <SpeedEvil> Epoxying or otherwise coating the inside of the structure is not an issue.
[15:21:44] <SpeedEvil> The issue is will interstitial condensation build up moisture behind the coating in such a manner to damage the structure,
[15:22:01] <SpeedEvil> And will condensation on the cold walls cause issue.
[15:22:09] <malcom2073_> SpeedEvil: It will, the ceiling is open on the other side
[15:22:18] <SpeedEvil> you almost certainly want insulation with a small air gap behind it.
[15:22:29] <malcom2073_> Yeah, I'm going to insulate the walls
[15:22:40] <SpeedEvil> All the way around - if you want to actually insulate - and ventilate the airgap
[15:23:03] <malcom2073_> There's an idea, put vents at the top of the wall all the way around
[15:23:12] <malcom2073_> Since there's no attic to facilitate airflow
[15:23:20] <malcom2073_> behind the wall
[15:23:59] <SpeedEvil> Or a small fan, and vented pipe to keep the rear dry
[15:24:15] <MattyMatt> a core of breeze blocks would provide the air gap in a wall
[15:25:00] <malcom2073_> MattyMatt: That's what the walls are made out of

[15:25:44] <MattyMatt> so where's the slab? on the floor?

[15:59:22] <archivist> looks like a southbend copy
[15:59:57] <cradek> I don't think cnc would make that lathe much more useful than it is
[16:00:16] <archivist> I keep my southbend manual :)
[16:00:45] <cradek> how would you change tools or change spindle speed or drill or tap?
[16:01:13] <bjm_> Kind of my opinion also, but I saw that price in my daily craigslist search so i figured I'd ask.
[16:01:32] <archivist> get it for your manual machine
[16:04:20] <ssi> not really the best manual machine either
[16:05:19] <cradek> meant for doing basic one-off things at a home or farm shop
[16:05:19] <archivist> better than none at all
[16:05:26] <ssi> sure
[16:05:39] <archivist> cant beat manual for one off

[16:06:49] <pcw_home> At least they are metal gears, not plastic like my rubbery HF
[16:08:04] <cradek> can't tell if it has a threading dial

[16:53:28] <MattyMatt> I still don't regret getting a lathe without change gears, as I do mostly metric threads
[16:54:02] <MattyMatt> still with taps and dies, until I get cnc on my little lathe
[16:55:35] <MattyMatt> just one axis to start. stepper on the leadscrew and encoder on the spindle. I might run it on an arduino with a little LCD to set a simple feedrate
[16:58:43] <MattyMatt> cnc on the compound would be handy too, because these threads might be tapered or in ptfe where a relief channel becomes a stress riser
[17:04:11] <MattyMatt> plan B is still to scratchbuild a full cnc slantbed, but I'm holding off until I can make it in metal
[17:04:33] <MattyMatt> I could call the plywood version a prototype I guess :)
[17:06:01] <MattyMatt> this is a small lathe I'm talking about 5x12 approx

[17:06:54] <zeeshan|2> cute lathe.
[17:07:44] <MattyMatt> my current one is about that size too
http://imgur.com/a/piCdr#4
[17:08:52] <zeeshan|2> i like your model of a chuck :)
[17:10:05] <MattyMatt> measurements taken from my real one
[17:10:44] <MattyMatt> I've got the whole lathe modelled just about
[17:11:28] <ssi> zeeeee
[17:11:56] <ssi> zeeshan|2: more tools came in, reorganizing the box

[17:12:13] <MattyMatt> I need to do the chuck as a parametric script, for any size, non-whitworth screws, 7 jaw option etc
[17:12:19] <ssi> all the sheet metal tools were in a long drawer, I consolidated them to a short drawer
[17:13:40] <MattyMatt> my spanner drawer was intended for cutlery. green felt lining tho
[17:13:55] <zeeshan|2> NICE
[17:13:58] <zeeshan|2> er caps
[17:14:06] <ssi> it's caps appropriate :D
[17:14:38] <zeeshan|2> how much did that drawer full of tools cost? 100000?
[17:14:39] <zeeshan|2> :)
[17:14:47] <ssi> ugh it wasn't cheap :)
[17:14:49] <ssi> wasn't quite 100k
[17:15:14] <ssi> oh god you're gonna make my ocd do something else horrible:
[17:15:22] <ssi> spreadsheet of everything in the toolbox, part numbers, and list prices
[17:15:26] <zeeshan|2> id like a wrench set from snapon
[17:15:29] <zeeshan|2> rofl
[17:15:33] <ssi> I have a second set coming
[17:15:36] <zeeshan|2> dude i started on one drawer
[17:15:39] <ssi> I found another good deal after I got the first one
[17:15:44] <MattyMatt> for 100k you could take a year off work, buy a forge, learn to forge, build a drop hammer, etc etc etc
[17:15:47] <zeeshan|2> and stopped half way for my machinist tools
[17:15:48] <ssi> and I may sell whichever set I'm less happy with
[17:16:02] <zeeshan|2> how much is the wrench set?
[17:16:04] <zeeshan|2> typically
[17:16:43] <MattyMatt> all the nice girls like a blacksmith
[17:16:44] <ssi> a lot :P
[17:16:48] <ssi> http://buy1.snapon.com/catalog/item.asp?P65=&tool=all&item_ID=633147&group_ID=674992&store=snapon-store&dir=catalog
[17:16:54] <ssi> 3/8-1 is $438
[17:17:06] <ssi> plus I added downward, 11/32 5/16 1/4
[17:17:15] <zeeshan|2> i mean used
[17:17:25] <zeeshan|2> those prices arent even what the snapon truck charges
[17:17:25] <zeeshan|2> :P
[17:17:29] <ssi> I got the first 3/8-1 set for about $220
[17:17:41] <ssi> and then like $15 apiece for the bottom three
[17:17:43] <ssi> so sub-300
[17:17:52] <ssi> the second set was 1/4-1 and I got it for $200
[17:17:55] <ssi> which is why I jumped on it :P
[17:18:17] <ssi> plus I bought a set of angle wrenches in standard and metric
[17:18:29] <anomynous> metric is standard
[17:18:30] <anomynous> duh

[17:18:41] <ssi> those tend to sell for about 215
[17:18:48] <ssi> again, got them for 175, had to jump on it
[17:19:09] <ssi> every A&P I've ever known has lusted after angle wrenches, if they didn't already have some :P
[17:20:00] <anomynous> i maded a keyway into a few ballscrews and drilled holes and emptied trash cans and drove a forklift and drank coffee and what else.
[17:20:17] <ssi> yay productivity :)
[17:20:32] <anomynous> and ate cake
[17:20:34] <ssi> zeeshan|2: what's your opinion on tool finish? chrome, industrial black oxide, what do you like
[17:20:35] <anomynous> we had cake at work
[17:20:35] <zeeshan|2> those are brand new..
[17:20:42] <ssi> yes, exactly
[17:20:54] <zeeshan|2> they are cheap used
[17:21:04] <ssi> not much cheaper
[17:21:13] <ssi> I've been watching some used sets, they get high at the end
[17:21:16] <MattyMatt> I want colour coded sockets
[17:21:27] <ssi> I bought a used set of standard angle wrenches for BJ
[17:21:31] <ssi> I think it ended up at 155
[17:21:31] <zeeshan|2> i like the crinkled finish
[17:21:35] <zeeshan|2> it looks like microshot blasting
[17:21:42] <anomynous> colour coded sockets? what for?
[17:21:46] <ssi> what brand?
[17:21:53] <zeeshan|2> proto
[17:22:09] <MattyMatt> like resistor colour codes. size and metricity in 2 or 3 bands
[17:22:24] <ssi> I've never used proto stuff
[17:22:31] <ssi> MattyMatt: harbor freight sells color coded sockets :P
[17:22:47] <MattyMatt> yay. tell them to open a store in UK

[17:24:49] <MattyMatt> it'd wear off too quick
[17:24:50] <ssi> probably won't hold up very lonhg
[17:25:01] <anomynous> put them in lathe and make little grooves
[17:25:08] <ssi> that's not a bad idea :P

[17:27:34] <anomynous> why dont everyone just start using allen keys and forget everything else

[17:28:38] <MattyMatt> now I need drills in 1/64 and a handy metric conversion table, because at those sizes I think in mm

[17:29:29] <zeeshan|2> there would be a lot more bolt ownage
[17:29:37] <zeeshan|2> w/ all the crud inside the head
[17:29:39] <anomynous> when you are under a car and you want a wrench you always notice you didnt take THAT size with you

[17:43:00] <malcom2073_> heh
[17:43:09] <ssi> malcom2073_: I'm actually really impressed with that line of boxes
[17:43:21] <ssi> a mechanic friend of mine here at the airport has had one for awhile, and I always assumed it was a snapon box
[17:43:32] <ssi> when I started talking to him about it, and found out it was HF, I went and bought mine that day
[17:43:43] <malcom2073_> Yeah they have some decent boxes
[17:43:45] <ssi> the only thing I don't like about it, it has plastic locks for the drawers
[17:43:51] <ssi> and they break off within a few uses
[17:43:56] <malcom2073_> Eh, I don't need locks
[17:44:00] <CaptHindsight> I want a set of wrenches with the ~10ft extension handles like in the video jymmm posted
https://youtu.be/VfwpF68Di8k?t=3m
[17:44:24] <ssi> not the keylock stuff, there's like a little handle that you pull while you're opening the drawer
[17:44:30] <ssi> keeps the drawrs from opening when you roll it around
[17:44:37] <ssi> the slides still have teh usual detents, but they have the locks as well
[17:44:42] <ssi> they're just junk locks sadly
[17:44:56] <malcom2073_> ah heh
[17:45:40] <ssi> CaptHindsight: what in the world would you do with those?
[17:46:20] <zeeshan|2> can anyone here speak japanese

[17:47:25] <ssi> "exhibition wrenching"
[17:47:38] <ssi> sounds like a spectator sport that not many people would pay to attend :)
[17:47:47] <CaptHindsight> they do it with shooting so why not
[17:47:56] <ssi> fair enough :D
[17:48:10] <Jymmm> ssi: It's got 120KV, of course they'll pay!
[17:48:31] <ssi> as long as there are occasional accidental deaths, people will pay

[17:48:51] <ssi> holy crap he's running a torque wrench with it
[17:49:00] <Jymmm> lol
[17:50:09] <Jymmm> I like the whole rotating wrenching action
[17:50:14] <ssi> yea
[17:50:53] <malcom2073_> "Now with rotating wrenching action!!!"
[17:51:12] <Jymmm> Funny thing, I never saw a lockout on the control panel
[17:55:36] <Sync> it is not mandatory here
[17:55:37] <andypugh> Jymmm: Why would they need a lockout on the control panel? They were working upstream of it.
[17:55:53] <Sync> well, the grounding bar could come off
[17:55:54] <Jymmm> andypugh: the grounding strip
[17:55:59] <Sync> but that's all in the end
[17:56:08] <Sync> it is grounded on the other side as well
[17:56:09] <Sync> so eh
[17:57:43] <archivist> the bit to carry the lockout is the bit they were going to service
[17:58:03] -!- persina has quit [Quit: Page closed]
[17:58:41] <Sync> well, not really, at least you are supposed to put a "men working" sign on the grounding bar switch, at least in germany

[17:58:47] <Jymmm> archivist: The one witht he 120KV 12" arc you mean?
[17:58:57] <Sync> like a switch on the motor line to the grounding bar
[17:59:04] <Sync> so they know nobody fucks with it
[17:59:33] <archivist> yes those wires go to the breaker itself

[19:45:19] <gonzo_> HAL: ERROR: function 'hm2_7i90.0.read' not found
[19:45:45] <gonzo_> though I know the interface works, as I managed to use mesaflash to load/verify the firmware
[19:45:50] <gonzo_> any clues?
[19:52:52] <PCW> is that the first error? sounds either like the driver didn't load or there's a name issue

[19:56:49] <gonzo_> Yep, in the Dubug File Information, that is the first
[19:57:35] <Erant> PCW: Do you guys do first day on USPS? I called yesterday and the lady said my order was being filled. Just curious if I'll be able to make chips this weekend, or if I have to wait 'til next.
[19:59:02] -!- radish has quit [Ping timeout: 272 seconds]
[19:59:54] <PCW> we are really behind on shipments so nothing is going to be shipped very soon after an order
[20:00:29] <PCW> gonzo_ what is your parallel port address?
[20:01:02] <PCW> I think the default is 0x378 if unspecified
[20:01:12] <gonzo_> 0x378 I believe (that's what I used for mesaflash)
[20:01:27] <TekniQue> 378 is the address of the first parallel port
[20:01:36] <TekniQue> 3BC is the second IIRC
[20:01:47] <TekniQue> and then the third was 278 wasn't it
[20:02:03] -!- skunkworks has quit [Ping timeout: 255 seconds]
[20:02:11] <gonzo_> yep, just checked the mesaflash --verify at that address. All fine
[20:02:55] <gonzo_> I did add ioaddr=0x378 to the .hal file. But made no difference
[20:03:32] <gonzo_> I saw soe reference to adding loadrt epp, but it complained that it could not be found
[20:04:30] <PCW> so if thats the case I would try:

[20:09:33] <gonzo_> (Using 7i90_epp_svst4_8_ado)
[20:11:23] <Erant> PCW: I ordered three weeks ago, what's my chances?
[20:18:26] <Tom_itx> gonzo_, did you make the bitfile?
[20:19:13] <PCW> gonzo_ just tried with linuxcnc 2.7.1, works as expected
[20:19:15] <PCW> 7i90.ini file is only different from 7i43.ini in 3 ways:
[20:19:16] <PCW> card=7i90
[20:19:18] <PCW> driver=hm2_7i90
[20:19:20] <PCW> config line has firmware token removed
[20:19:58] <PCW> loads and runs
[20:20:00] <PCW> a bitfile problem would most likely spew a bunch of errors
[20:20:22] <PCW> Erant: what order number?
[20:20:28] <Tom_itx> well i compiled one with the wrong size chip once
[20:20:55] <Tom_itx> that's why i asked if he generated the bitfile
[20:20:59] -!- PetefromTn_ has quit [Quit: I'm Outta here!!]
[20:22:26] <gonzo_> PCW, that looks like what I have in the ini file.
[20:22:39] <gonzo_> the bit file is one that came with the 2.7.1 install
[20:22:46] <PCW> what linuxcnc version do you have?
[20:24:14] <PCW> OK 2,7.1 just worked for me, not sure if the 7i90 config was part of 2.7.1 or not but it launched OK
[20:25:05] <gonzo_> what bitfile do you suggest I try?
[20:25:07] <PCW> (its the hm2_servo demo)
[20:25:51] <PCW> I dont suggest you mess with bitfiles at all, if you dont have the read function thats unrelated
[20:29:08] <gonzo_> ok, tried the hm2_servo demo/example config
[20:29:55] <PCW> heres the beginning of the 7i90.ini file for hm2_servo:
[20:29:57] <PCW> [HOSTMOT2]
[20:29:59] <PCW> DRIVER=hm2_7i90
[20:30:00] <PCW> BOARD=7i90
[20:30:01] <PCW> CONFIG="num_encoders=3 num_pwmgens=3 num_stepgens=0"
[20:30:30] <gonzo_> I get mh2-servo.hal:45: parameter or pin 'hm2_7i90.pwmgen.pwm_frequency' not found 6663
[20:30:32] <PCW> that's all the 7I90 specific changes
[20:31:32] <gonzo_> ah, let me add thiose
[20:33:16] <gonzo_> ah, I think I was missing the CONFIG
[20:33:40] <gonzo_> though that was only needed for the boards where you upload the firmware
[20:33:45] <gonzo_> at load time
[20:35:46] <gonzo_> PCW, thanks a lot for the help

[21:50:15] <andypugh> I should just get a cheap chinese spindle to bolt on the face of the overarm. It wouldn’t even be difficult.

[21:50:56] <andypugh> They made my spindle in a 2500 rpm version, it is just that my particular machine got both slow ratios
[21:51:32] <andypugh> I am thinking of making a speeder, I have a design in mind, but actually a high speed spindle would be easier and cheapr

[23:53:37] <andypugh> Not really. At one point DMM asked if i could “LinuxCNC certify” them, but I had to admit we had no such process.
[23:53:38] <PetefromTn_> I have heard good things on them on the zone
[23:53:58] <PetefromTn_> they made me what I consider a great deal
[23:54:20] <PetefromTn_> I am just afraid of the customs fees they will impose when I receive them
[23:55:01] <PetefromTn_> I got the complete package with drives, motors, cables for power and encoders, tuning cable, software etc.
[23:55:26] <andypugh> Is it worth hopping over the border to collect them?
[23:56:05] <PetefromTn_> hehe no I doubt it
[23:56:18] <PetefromTn_> its SUPPOSED to be less than 10percent
[23:56:40] <PetefromTn_> so that should be less than a hundred bucks but they said they cannot detemine exactly
[23:57:30] <andypugh> You might be able to guess by pretending to buy something from eBay from CA
[23:57:41] <andypugh> Sorry, I meant .ca
[23:58:07] <PetefromTn_> as long as it does not go over a hundred I willl be fine with it.
[23:58:40] <PetefromTn_> either way it is WAY less than I would have been paying for anything reasonably this nice that I have found so far.
