[00:22:38] <tjb1> Hey JT-Shop
[00:22:49] <tjb1> Got my 3030 extrusions for $.81 an inch
[00:23:16] <JT-Shop> nice score
[00:23:52] <JT-Shop> now tell me where the self drilling sheet metal screws with the large flat head are hiding in my shop...
[00:24:03] <tjb1> Last place you would look.
[00:24:31] <tjb1> Or probably put away in a proper location
[00:24:36] <tjb1> I lose stuff when I put it away
[00:24:53] <ReadError> i hope its the last place he would look ;)
[00:26:20] <taiden> what do you guys use for VNC on hardy?
[00:26:26] <taiden> I can't get anything to work it's driving me bonkers

[02:17:53] <uw> how do you place the parts Tom_itx?
[02:19:34] <Tom_itx> i made a pick n place wand

[02:21:38] -!- delkin has quit [Quit: Lost terminal]
[02:27:41] <elmo40> anyone know of a 'deep hole' pecking cycle that will start half way in the hole (after you change to a longer drill bit) but still retract to the top of the part so chips clear out?
[02:28:10] <toastydeath> elmo40, there are more than one peck drill mode
[02:28:26] <toastydeath> i'm not sure how emc handles it, but there's an R word on most controls called the retract height
[02:28:43] <elmo40> that's not what im looking for
[02:28:46] <toastydeath> ?
[02:29:05] <toastydeath> you position the drill in the hole where you want it, but the cycle still clears to the top of the part
[02:29:13] <toastydeath> maybe i'm not understanding what you want to do
[02:29:16] <elmo40> when you change from a short pilot drill to a longer drill you start middle of the part. but to clear chips you need to retract to top of part.
[02:29:20] <toastydeath> yesd
[02:29:31] <toastydeath> and the retract height can handle that because it is bimodal
[02:30:00] <toastydeath> i'm not sure how EMC deals with it or what the relevant g code is to switch between the two modes
[02:30:14] <Tom_itx> G83 should be a deep hole cycle
[02:30:18] <elmo40> but when I put in that retract yet give the z for starting the hole, it starts the peck from the retract height.
[02:30:27] <Tom_itx> dunno how linuxcnc supports it though
[02:30:29] <elmo40> Tom_itx: sure, if you use one drill
[02:30:53] <toastydeath> elmo40, what mode is the retract height in.
[02:30:55] <Tom_itx> well if you're using 2 drills set the retract up different on the 2nd drill
[02:31:11] <toastydeath> it sounds like you're in the wrong mode
[02:31:15] <toastydeath> which is clearance mode
[02:31:33] <Tom_itx> and set your z height to the depth you've already drilled
[02:31:35] <toastydeath> where the Z height is the travel height to clear the part, and the R height is the start height for the hole
[02:31:41] <toastydeath> the other mode is reversed
[02:40:04] <elmo40> ok, let me explain, again... with a photo ;) http://image.bayimg.com/fapnpaadf.jpg

[02:47:22] <elmo40> clear as mud?
[02:47:43] <elmo40> when I put the same retract, so it clears the chips, it wants to start from there.

[02:49:01] <Tom_itx> and raise the retract
[02:49:03] <elmo40> but I need it to start from mid-point, but retract after each peck to the ARE

[03:01:22] <Tom_itx> looks like you can use Q OR I J and K
[03:01:30] <ReadError> latest cnc project ;)
[03:05:18] <toastydeath> elmo40, that is what R can do
[03:05:42] <toastydeath> you just have to find the g or m code that tells the machine what the R value actually represents
[03:06:06] <toastydeath> because by default it uses the safe option - which is to pretend the Z height is the safe retract height, and the R height is the work height
[03:06:16] <toastydeath> You want Z to be the work height and R to be the retract height
[03:09:20] <toastydeath> (that is the default because it's easy to crash the machine drilling holes at the bottom of pockets otherwise)

[04:19:25] <Jymmm> Nice chunk of wood, but I don't have any ideas... http://sfbay.craigslist.org/sby/zip/3059920797.html djdelorie, you???
[04:21:53] <cpresser> Jymmm: you could slice it into pieces and make a nice finish (grind, oil). then put small markers into the annual rings and put a text next to it, indicating historical events
[04:22:10] <cpresser> have the wood tell the local history
[04:22:23] <Jymmm> nice idea
[04:23:49] <Jymmm> could even inlay the markers
[04:24:13] <cpresser> there is one in our hometown. it was covered in epoxy and polished to high gloss
[04:25:57] <cpresser> its about 400 years old; and there are markings in it for all kind of things
[04:26:33] <Thetawaves> http://nbitwonder.com/blog/tag/voip32/
[04:26:54] <Jymmm> It's FAR too big for *ME* to do anything with, but for free, would be nice for someone creative.
[04:28:50] <Jymmm> Thetawaves: since i have nfc what voip32 is, eh =)
[04:29:04] <Thetawaves> actually i was trying to show retrobsd
[04:29:11] <Thetawaves> http://retrobsd.org/
[04:29:13] <Jymmm> but that they recently added dhcp, no thanks =)
[04:30:07] <Jymmm> but I blame that on bsd more than anything else
[04:30:17] <Thetawaves> b;ame what?
[04:30:28] <cpresser> Thetawaves: thats a cool project. it might save me a lot of trouble for my upcoming PIC32-Projects :)
[04:30:50] <Thetawaves> what you doing with pic32?
[04:31:23] <Thetawaves> i got a pic32 starterkit in the mail last friday :D
[04:31:43] <cpresser> mine is still on its way... i intend to build a DMX-Recorder
[04:31:53] <Jymmm> a what?
[04:32:03] <Jymmm> is that the light show thingy?
[04:32:09] <cpresser> DMX is a digital protocol used in show lighting
[04:32:10] <Thetawaves> stage lighting
[04:32:53] <cpresser> i had to buy one for a past project.. it was expensive as hell.. so i decided to build my own :)
[04:33:07] <Jymmm> projects already exist for it
[04:33:42] <cpresser> sure.. but i still want to create my own

[04:38:37] <Thetawaves> no, a small generator
[04:38:45] <Jymmm> ah
[04:40:40] <Thetawaves> i also want to build a matching vawt generator
[04:40:46] <Jymmm> gas/diesel generator or some hybrid funky nuclear hydrogen generator?
[04:41:14] <Thetawaves> vawt is the wrong term
[04:41:26] <Thetawaves> but the kind of 3/5 phase generators commonly used in those
[04:41:42] <djdelorie> Jymmm: I've seen bigger
[04:42:03] <Thetawaves> if i buy a house, i'd like to tie a regular gas generator into the natural gas system
[04:42:09] <Jymmm> djdelorie: But, what would you do with it is the question
[04:42:23] <djdelorie> Peter turns them into lampshades. www.woodshades.com
[04:42:24] <Jymmm> Thetawaves: gasoline + natural gas?
[04:42:46] <Thetawaves> sure, but it will probably not see much gasoline use
[04:43:17] <Jymmm> Thetawaves: I want to get the kit to turn my eu2000 into gas/natural/propane
[04:43:26] <Jymmm> djdelorie: those are pretty
[04:43:45] <Thetawaves> have you considered just winging it?
[04:43:49] <djdelorie> they're prettier in real life, we've got one in our living room
[04:44:01] <Jymmm> $2400 holy shit
[04:44:07] <Jymmm> Thetawaves: winging it, hiw?
[04:44:42] <Thetawaves> just get that thing that turns the liquid into a gas, and use some old regulator you've got

[04:46:14] <paresh> looking for emc2 engraving
[04:47:38] <cpresser> paresh: ask a question :)
[04:47:38] <Jymmm> Thetawaves: Some are syaing they're getting better performance with propane than gasoline too
[04:48:26] <paresh> any body did engraving with emc2 with laser ?
[04:49:00] * Jymmm suspects a z axis question coming
[04:49:20] <cpresser> paresh: yes. search for it on youtube. its possible
[04:49:38] <paresh> i already search
[04:49:49] <paresh> but some confusion
[04:53:56] <Jymmm> Thetawaves: Kinda like the idea that you can use natural gas in a pinch, but propane for long term, and gasoline for whatever
[04:56:20] <Thetawaves> natural gas would be ideal because it's provided at my door
[04:56:31] <Thetawaves> i would have to get propane delivered
[04:56:35] <Jymmm> Thetawaves: in your case, natural gas for a permantent installation, and propane for a backup
[04:56:50] <Thetawaves> yeah, exactly
[04:56:56] <Jymmm> even a few 20# tanks
[04:57:18] <Jymmm> My gen is portable, so doesn't really apply.
[04:57:26] <Thetawaves> propane stores much better than gasoline too
[04:57:33] <Jymmm> for natural gas that is
[04:57:37] <Jymmm> oh big time
[04:57:58] <Jymmm> and I have 3 20# tanks for my portable heater
[04:58:15] <Jymmm> I use in the garage =)
[04:58:23] <Jymmm> I love that lil heater!!!
[04:58:42] <Thetawaves> how long does that last?
[04:59:18] <Jymmm> 20# tank for the heater lasts about 100+ hours on the low setting
[04:59:40] <Thetawaves> impressive
[04:59:40] <Jymmm> there's only low (4000btu) and high (9000btu)
[05:00:06] <Jymmm> the Big Buddy goes up to 18000 BTU
[05:00:43] <Jymmm> It's nice in the fact that it uses 1# disposable tanks

[05:00:50] <Jymmm> but they dont last long =)
[05:01:18] <Jymmm> so I have the 10ft hose for it that attachs to 20# tanks which I get refilled for $16 out the door
[05:02:14] <Jymmm> I picked up cheap old tanks off craigslist, then took them to Lowes for $21 exchanged for newer tanks. then I just get them refilled after that.
[05:02:30] <Thetawaves> damn!
[05:02:37] <Thetawaves> can i do that?
[05:03:25] <Jymmm> Thetawaves: They can't be older than 12 years without being recertified, but lowes will tank back ANY tank for exchange. Just be usre to select which tank you get from them so it's no mor ethan just months old.

[05:20:22] <Thetawaves> in the hot climates, you might not even need that
[05:20:26] <Jymmm> Oh sure, but a far better setup... quick release. no bulky regulator bolted to the side
[05:20:51] <Jymmm> Though I would sorta reinforce the 2nd reg on the tank.... looks scary =)
[05:21:18] <Thetawaves> i was thinking that too
[05:21:56] <Jymmm> Maybe the 1st attached to the tank with a 12" hose to the 2nd reg "hanging" aroudn the ring of the tank.
[05:22:22] <Jymmm> or even MAG mount to the tnak itself
[05:23:02] <Thetawaves> i was thinking stack the regulator and converter
[05:23:10] <Thetawaves> with u pipe
[05:23:12] <Jymmm> NICE.... at the end he just disconects the quick release while it's running and no gas leaks
[05:24:03] <Jymmm> I was thinking a "ring" around the neck of the tank, connected to a L bracket, then a magnet so it doesn't flop around.
[05:25:17] <Jymmm> The ring having a 9" ID to just slip over the neck and a 10 or 11" OD
[05:25:39] <Thetawaves> -0.5wc? hmmmmm
[05:25:46] <Jymmm> vacuum
[05:25:56] <Jymmm> but I have nfc on those regulators
[05:27:11] <Jymmm> Thetawaves: This is the hose I bought. The are now black with no plastisizers in them http://www.northerntool.com/shop/tools/product_200362084_200362084
[05:27:24] <Jymmm> Thetawaves: no wrench needed either
[05:28:51] <Jymmm> This is the BIG Buddy http://www.northerntool.com/shop/tools/product_200307957_200307957
[05:29:39] <Jymmm> Thetawaves: This is the one I have http://www.northerntool.com/shop/tools/product_200395499_200395499
[05:29:52] <Jymmm> that's a good price too $80
[05:30:36] <Jymmm> Thetawaves: you can buy the adapter to refill #1 tanks from 20# tanks too if you like
[05:38:19] <Thetawaves> hmmm

[11:20:04] <gmagno> hello, you guys know the best way to verify if a nema 17 motor is working? I bought one of those TB6560 driver board + 3x nema 17 motors kit, but since I can't put it to work with the linuxCNC software, I am considering the motors might have some problem (it is always hardware fault... :P ) How can I check if the stepper motors are ok?
[11:21:12] <gmagno> I am considering applying some voltage to one of the coils, but I wouldn't like to burn the motor... :-/ This is the kit I bought: http://www.ebay.com/itm/300654822440?_trksid=p5197.c0.m619
[11:22:37] <Valen> if the voltage is below the voltage stamped on the motor it should be ok
[11:25:58] <gmagno> Valen, THe problem is that I can't find a max specified voltage... They say the motor has the following current and resistance scpecifications: 1.8ohm/phase and 1.8A/phase. Should the operating voltage be 1.8*1.8? :-S
[11:26:12] <Valen> V = IR
[11:26:20] <Valen> so yes
[11:36:07] <gmagno> Ok, I should find a 3V power supply now... :-S
[11:36:20] <Valen> just use a AA battery
[11:36:31] <Valen> you should see it jump and it'll be hard to turn
[11:39:16] <gmagno> Valen, gonna do just that!
[11:41:14] <gmagno> Valen, there should be no problem in actuating only one coil as far as i know, right? (there are some shaft positions where only one of the coils is being actuated, right?)
[11:42:30] <Valen> should be fine
[11:42:47] <Valen> disconnect it from any other electronics first though
[11:50:33] <jthornton> archivist, for your amusement http://gnipsel.com/linuxcnc/tutorial/index.html

[11:58:38] -!- asdfasd has quit [Ping timeout: 255 seconds]
[12:01:11] <gmagno> jdh, I'm not sure what lock up means, but when I run the stepconf wizard, and test one of the axis, pressing the arrows I can hear that typical sound of a shaft turning, but nothing really moves... It sounds like something is moving inside but the shaft does not
[12:02:37] <Tom_itx> then maybe they are wired wrong
[12:03:04] <Loetmichel> gmagno: when the drivers are powered the Stepeprs should be "locked" in place, if you try to turn them by hand you have to use MUCH more force opposed to drivers being off
[12:03:07] <Tom_itx> i use a 1.5v battery to find what i need sometimes
[12:03:09] <Tom_itx> or a meter
[12:04:06] <Loetmichel> hmm, do you have couplings on the stepper shafts?
[12:04:41] <Loetmichel> maybe the stepeprs turn but the leadsrews not because of slipping couplings?
[12:04:45] -!- psha[work] [psha[work]!~psha@] has joined #linuxcnc
[12:09:11] <jdh> or step timings are way off
[12:09:16] <gmagno> Loetmichel, I have the motors unloaded. They only have a little flag to tell me if they move. About the wiring, I'm almost sure (I'm never completely sure about anything...) that they are well connected. Ive done some measurements with a multimeter and also did that test of turning the shaft when a coil is shunted
[12:10:31] <gmagno> ok, I just did that test of applying a DC battery to the motor, and the shaft did move a tiny bit which I believe is good
[12:10:44] <gmagno> gonna do that for the other two

[12:14:17] draig_ is now known as draig
[12:16:23] <Loetmichel> gmagno: if you connect the two coils of the stepper in this manner to the battery the stepper should move continously (one tiny step at a time)
[12:16:25] <Loetmichel> coil1 + -
[12:16:25] <Loetmichel> coil2 + -
[12:16:25] <Loetmichel> coil1 - +
[12:16:25] <Loetmichel> coil2 - +
[12:16:25] <Loetmichel> repeat from start
[12:17:05] <Loetmichel> if it does: steppers ok, then something with your drivers and/or cabling isnt ok
[12:20:12] <jdh> do all steppers fail to operate?
[12:20:41] <gmagno> jdh, yes. Loetmichel, is that a series, or paralel?
[12:21:05] <Loetmichel> gmagno: that is seperate
[12:21:24] <Loetmichel> coil 1 energized +- , coil2 open
[12:21:26] <jdh> not likely to be a motor problem then.
[12:21:34] <Loetmichel> coil 1 energized +- , coil1 open
[12:21:36] <Loetmichel> and so on
[12:21:58] <gmagno> Loetmichel, how should th shaft move continuously?
[12:22:03] <Loetmichel> thats the full step sequence the stepper driver does also
[12:22:38] <Loetmichel> every time you energize a coil in this sequence the shaft will move a step in the same direction
[12:22:56] <gmagno> ah i see
[12:24:16] <gmagno> jdh, I'm almost sure now that it is not a motor problem. I'm gonna do the energizing sequence Loetmichel suggests
[12:25:13] <Loetmichel> gmagno: do you have the right pins in the linuxcnc config?
[12:25:48] <Loetmichel> 'cause the "movement sound" but no movement has occured to me as i had spitched the pins for step and dir in the config
[12:25:55] <Loetmichel> switched
[12:26:07] <Loetmichel> accidentally
[12:26:36] <Loetmichel> which driver board do you have?
[12:27:05] <gmagno> I'm following this guy procedure: http://www.youtube.com/watch?v=oiXjSZ3tIr0 My board is this one: http://www.ebay.com/itm/300654822440?_trksid=p5197.c0.m619
[12:28:36] <Loetmichel> so do you have a pinout of YOUR driver board?
[12:28:49] <Loetmichel> to verify the io pins in LinuxCNC?
[12:29:32] <gmagno> Loetmichel, you mean for the paralel port, right?
[12:29:40] <Loetmichel> correct
[12:30:12] <Loetmichel> IIRC the normal tb6560 board uses a different pinning as in the youtube video
[12:30:17] <Loetmichel> i have some here ;-)
[12:30:23] <Loetmichel> boards
[12:31:03] <Loetmichel> http://www.youtube.com/watch?feature=player_detailpage&v=oiXjSZ3tIr0#t=6s <- this looks wrong for tb6560-boards
[12:31:39] <gmagno> Loetmichel, I found the pinout, I have some documentation the chineese guys sent me by email :)
[12:32:06] <Loetmichel> so look into your confing if its correct
[12:32:09] <gmagno> gonna check if it corresponds to the settings current settings
[12:32:14] <gmagno> yup
[12:32:17] <gmagno> one sec
[12:37:29] <gmagno> Loetmichel, I'm not sure about some of the pins, for instance, there is one pin that says "All axis enable"... there is no similar function in stepconf pinout configuration :-/any idea which should be?
[12:38:49] <gmagno> should it be "Amplifier Enable"?
[12:39:45] <gmagno> going to try that one
[12:40:21] <gmagno> and I'm going to ignore the Mill to PC signals (limits)
[12:44:55] <gmagno> weird
[12:46:13] <Loetmichel> gmagno: just a moment, booting my cnc
[12:47:22] <gmagno> the motors now emit a sound like TV static. And when I press the button to text the axis they shut up and the board does a CLICK out loud.
[12:47:37] <Loetmichel> hrhr
[12:47:45] <Loetmichel> the clic could be the spindle
[12:47:47] <Loetmichel> relais
[12:48:01] <Loetmichel> the static is a good sign
[12:48:04] <gmagno> right! Let me try it again
[12:48:17] <Loetmichel> its the pulsed current through the motors
[12:48:33] <Loetmichel> sounds more or less like an opened tap
[12:48:36] <Loetmichel> water tap
[12:49:21] <gmagno> Loetmichel, that click is the relays indeed. About the TV static sound do you think it is ok?
[12:49:52] <Loetmichel> yeah
[12:50:04] <Loetmichel> hmm, my stepconf is german
[12:50:25] <Loetmichel> here the enable pin is labeled "endstufe aktivieren"
[12:50:39] <Loetmichel> more or less "enable drivers"

[16:57:17] <micges> hi
[16:57:53] <IchGuckLive> micges: can you direct me to the place where the all G5x Zero entry Button is in the Mashine menue
[16:57:57] <IchGuckLive> i cand find it
[16:59:35] <micges> I don't understand
[17:01:05] <IchGuckLive> if been told by -> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?CoordinateSystems#Zero_Coordinate_System tat there is somthing that resets all G5x to zero with a buttonpress
[17:01:30] <IchGuckLive> Zero Coordinate System in the Machine menu its not there
[17:02:41] <IchGuckLive> im on 2.6.0-pre0-3090-g2368c21
[17:04:42] <micges> easiest is to put zeros into var file to parameters 5221 to 5390
[17:04:54] <micges> while emc closed
[17:06:19] <IchGuckLive> i know that but for a teatching lesson its not practical
[17:06:30] <micges> I don't see zero all button
[17:06:45] <IchGuckLive> with 50 people in the classrom
[17:07:01] <IchGuckLive> ok i ask jep
[17:07:09] <IchGuckLive> wher he lost that
[17:07:56] <micges> docs says that there is 9 buttons to zero 9 coord systems
[17:08:50] <IchGuckLive> but thay will then get the current position
[17:09:00] <IchGuckLive> and axis will display them in lines
[17:09:10] <IchGuckLive> so Zero entry woudt be best

[18:57:53] <archivist> for a spindle one may want to remove the seal for less friction
[18:58:24] <mrsun> tho they arent adjustable :/
[18:59:33] <archivist> I assume they will preload when done up tight, so no adjustment needed
[18:59:49] <mrsun> archivist, yeah but when they wear then ? :)
[18:59:51] <archivist> does mean good press fits etc

[21:00:26] <andypugh> How about a 7.2V cordless?
[21:00:27] <Tom_itx> $60
[21:00:50] <JT-Shop> it has to run all day long for a long time
[21:01:01] <JT-Shop> and I need encoder feedback
[21:01:12] <Tom_itx> AC or DC?
[21:01:25] <JT-Shop> doesn't matter
[21:01:28] <JT-Shop> at this point
[21:01:36] <Tom_itx> ^^
[21:02:40] <Tom_itx> about $100 by the time you add the encoder
[21:04:18] <DJ9DJ> gn8
[21:04:59] <JT-Shop> Tom_itx: yea something like that
[21:05:11] <JT-Shop> what does skewed rotor mean?
[21:05:20] -!- DJ9DJ has quit [Quit: bye]
[21:05:23] <Tom_itx> the rotor shims are skewed
[21:05:28] <Tom_itx> not straight across
[21:05:40] <JT-Shop> what does that do?
[21:05:51] <Tom_itx> beats the hell outta me.
[21:05:57] <Tom_itx> it smooths the torque?
[21:06:02] <JT-Shop> lol me too
[21:06:10] <Tom_itx> i think that's what it does
[21:06:35] <andypugh> Reduces cogging.
[21:06:50] <JT-Shop> lol it is a keling motor
[21:07:02] <Tom_itx> well that just figures
[21:07:16] <Tom_itx> i bet i could put you in contact with a china source i have
[21:07:35] <andypugh> If you go to Kelininc.com it says "please visit out now web site, automationtechnolgies….
[21:07:55] <Tom_itx> oh yeah i got a notice about that the other day
[21:08:05] <Tom_itx> didn't really register with me though
[21:08:28] <JT-Shop> ok, it is there new web site then
[21:09:19] <JT-Shop> the other part of the puzzle is I need to be able to just tell it to turn 3 times or some degrees of turn... real simple commands
[21:10:38] <andypugh> JT-Shop: WillemCMD id playing a simlar game. He is using HAL and a GaldeVCP GUI, but not the rest of LinuxCNC
[21:11:24] <JT-Shop> I actually want to get lower level than that and not have a pc at all in the loop
[21:11:25] <andypugh> So, Glade button sends target position to Limit3 component drives PID or Stepgen. Second button sets the tarhet positin back to home.
[21:11:26] <andypugh> ]
[21:11:28] <JT-Shop> any ideas?
[21:11:44] <andypugh> You said you wanted a dumb drive.
[21:11:58] <andypugh> Sounds like a job for a semi-smart drive.
[21:12:49] <andypugh> My experience has been that when you try to take a PC out of a system the alternatives cost more, and are a lot more difficult to reconfigure when the customer changes their mind.
[21:13:06] <Tom_itx> hmm somebody that makes those smart drives got one of my programmers.. i can't remember who it was now
[21:13:21] <andypugh> Paybe have a word with that spammer on the Forum. His PC is very tiny,
[21:13:46] <andypugh> The answer is probably an Arduino. It normally is.
[21:14:07] <JT-Shop> I was kinda thinking that the Arduino was a key part
[21:15:33] <andypugh> http://www.ebay.co.uk/itm/390431979950 (just saw it, not an answer to this question)
[21:17:27] <andypugh> The answer to the question might be the DMM-tech drive/motor combo with step-dir command from the Arduino: http://www.dmm-tech.com

[21:30:07] <Tom_itx> JT-Shop, do you have any specs on your servo motor?
[21:30:48] <JT-Shop> no, I'm just at the guess stage
[21:31:08] <Tom_itx> that guy in china may have a source if you need several
[21:31:45] <Tom_itx> he found an mpg for me but i'd already gotten one
[21:32:48] <Tom_itx> i got my last batch of pcbs from him

[21:37:34] <andypugh> JT-Shop: Another alternative might be a Mesa card running SoftDMC rather than Hostmot2.

[21:54:55] * Tom_itx thinks JT-Shop may need one of those
[21:56:54] <JT-Shop> got 3 cannons now in the shop, don't need any more!
