[00:04:30] <geo01005> anybody ever used EMC to make an electronic lead screw for a manual lathe?
[00:04:32] <andypugh> jcizek: I have been where you are, and I know how easy it is for us to say "swap computers", "build a new config", "try a different EMC2 version" and how much work that is in practice. All I can say is that EMC2 does actually work and is running thousands of machines worldwide. Remote diagnosis is difficult, and the chances are that none of our suggestions will help at all, but at some point you will see something and spot t
[00:04:32] <andypugh> problem.

[00:05:26] <andypugh> geo01005: Sort of. I made an electronic X axis too, and called it a full conversion.
[00:06:45] <jcizek> andy, thanks, i know.. i love EMC, i haven't had a SINGLE problem using it to run my Solsylva router table (as a matter of fact, i use the exact same controller for it, just carry it back and forth). I played with Mach and EMC is FAR superior software. I know i';ll get through it eventually, it's just frustrating!! Thanks for the support though, it's great to have you guys so willing to help!
[00:07:05] <andypugh> But you could use a spindle encoder, stepper, and EMC2 with a very simple HAL file to do an electronic leadscrew. That is pretty much what I did with my hobbing setup. I geared the milling spindle to the work spindle.
[00:08:07] <andypugh> geo01005: Have you seen http://www.youtube.com/watch?v=ZhICrb0Tbn4 ?
[00:08:55] <andypugh> (50seconds in)
[00:11:43] <geo01005> I see.
[00:12:29] <geo01005> I'm not too keen on doing a whole cnc conversion because it reduced flexibility on easy stuff, and that is pretty much all I plan to do on it.
[00:12:59] <andypugh> Actually, for a lathe, it can make the easy stuff even easier.
[00:13:01] <geo01005> The lathe I have has manual change gears, and I'm just looking at options to eliminate the gearbox.
[00:13:53] <geo01005> I'm wondering how much resolution on need on the spindle encoder.
[00:14:10] <andypugh> I don't write G-code for my lathe, I have predefined code for turning, facing, parting, threading, radius, chamfer etc. I put the feed, speed, tarhet X and target Y in entry boxes, and press the button for the operation I need
[00:15:14] <andypugh> So it's like a manual lathe, except it always stops the cut at the same place, returns and does the next cut, and keeps the surface speed constant.
[00:15:30] <geo01005> That sounds cool.
[00:15:49] <andypugh> http://www.bodgesoc.org/lathe/lathe.html
[00:17:07] <andypugh> It's great for threading. type in pitch, depth, nominal diameter and end-Z and press "Threading" and it all just happens.
[00:17:37] <geo01005> Very cool.
[00:17:42] <andypugh> Ony drawback is that there is no graphical preview in Axis.
[00:17:59] <andypugh> (because the code that runs isn't actually loaded)
[00:18:45] <andypugh> I have a feeling that my approach is pretty crude compared to ngcgui, which JT uses for much the same sort of work.
[00:19:54] <jcizek> andy, jt, tom, i'm gonna sign off.. neighbor just stopped by and needs help tracking down a wiring problem in his camper. I just got JT's comp file compiled and installed, i'll jump back on once i have everything in place and see if that goes smoother... A HUGE thanks to all of you for the help! You guys are great! have a good one....
[00:21:13] <andypugh> Good luck. Nothing like solving somebody else's problem to give you a break from your own :-)
[00:21:56] <jcizek> thanks! stepping away for a bit will probably be helpful to me... clear the head! have a good night everyone

[00:22:35] <geo01005> So is a single pulse per rev from the spindle sufficient to thread using EMC?
[00:22:55] -!- crazy_imp has quit [Ping timeout: 260 seconds]
[00:23:24] <andypugh> Barely.
[00:23:42] -!- czervika [czervika!~czervika@pool-96-244-94-63.bltmmd.fios.verizon.net] has joined #emc
[00:23:51] <andypugh> It can be done, but not necessarily repeatably
[00:24:19] <geo01005> So if my spindle changes speed with load, then I'll probably have some troubles.
[00:24:34] -!- crazy_imp [crazy_imp!~mj@a89-182-144-90.net-htp.de] has joined #emc
[00:25:09] <andypugh> Yes.
[00:26:20] <geo01005> dang, that is sort of what why gut was telling me.
[00:26:34] <geo01005> so andypugh, does your lathe have lots of backlash?
[00:27:02] <andypugh> No, mine has ballscrews now, so very little.
[00:29:07] <andypugh> But, if you take care with your G-code you can probably make backlash not matter on a lathe, by working round it in the same way as you do when running manually.
[00:29:26] <geo01005> mine has lots in both directions, I suppose I could just write the g-code to do the same thing I already do manually.
[00:29:37] <geo01005> ha, right.
[00:29:57] <andypugh> EMC2 does have backlash comensation as an option, too.
[00:31:03] <andypugh> Z-conversion of a lathe is generally very easy. X rather less so as it is hard to fit the motor in neatly.
[00:31:36] <Tom_itx> backwards with a pulley?
[00:31:49] <andypugh> That is what I did, yes.
[00:31:50] <geo01005> I was thinking of adding a lead screw extension on the back of the saddle.
[00:32:20] <Tom_itx> or let it hang with a couple pinion gears
[00:33:17] <andypugh> This was my solution (post 15 onwards) http://www.cnczone.com/forums/mini_lathe/63621-mini_lathe_cross_slide_ballscrew-2.html

[00:35:50] <Tom_itx> what size stepper is that?
[00:36:18] <andypugh> NEMA 23, 2-stack
[00:36:27] <Tom_itx> plenty of torque?
[00:36:55] <andypugh> Yes. It is almost perfect, never stalls on a cut, stalls when I mess up :-)
[00:37:03] <geo01005> I will probably use a servo motor if I do it.
[00:37:21] <Tom_itx> what board is it hooked to?
[00:37:26] <Tom_itx> 7i43?
[00:37:58] <andypugh> 7i43 then a Motion Control Products stepper drive.
[00:38:27] <Tom_itx> what sort of values do you have for max velocity and max acceleration?
[00:39:53] <andypugh> 800mm/min I think. Quite modest, but then it is quite a small travel.
[00:45:17] <andypugh> I have lost interest in making that lathe/mill any better. The base machine is just rubbish. As an example, I was wondering why the tailstock never seemed to clamp down tight. It is partly because the two slidways are not actually in the same plane, and partly because the clamp block under the bed is milled out for the clamp bolt head, then milled out so big for the bolt clearance that there is actually no land for one side
[00:45:17] <andypugh> bolt head, so all that tightening the nut does is bend the head some more,and eventually it will just pop through.
[00:45:25] <andypugh> (I can get a picture if you want)

[00:50:05] <andypugh> The X is a T2.5. No space for anything else, and so far its worked very well.
[00:50:25] <Tom_itx> i don't remember what i used on my bot
[00:51:11] <atom1> http://tom-itx.dyndns.org:81/~webpage/maxbot/maxbot_index.php
[00:51:16] <andypugh> The ballscrew and the belt drive all look far too flimsy and tiny, but have accually given me less trouble than the other axes.
[00:52:22] <atom1> http://tom-itx.dyndns.org:81/~webpage/maxbot/image016.jpg
[00:52:40] <Tom_itx> i think those are a smaller series

[00:53:38] <Valen> This page needs content. You can help by adding a sentence or a photo!
[00:53:44] <atom1> haha
[00:54:28] <andypugh> Wierd
[00:54:48] <andypugh> Add the last full stop by hand?
[00:55:32] <andypugh> (IRC is dropping the last "." from the URL
[00:56:25] <Valen> dude not even a spinner cmon ;->
[00:57:05] * atom1 whispers to Valen... i wonder how long we can keep him up
[00:57:08] <andypugh> We fitted a whirling thingy later
[00:58:13] <atom1> they had competitions with those here for a while
[00:58:30] <atom1> battlebots?
[00:59:12] <atom1> they put some hefty motors in some of those
[01:00:45] <andypugh> Aye, it started in the US. Robotwars was licensed from Battlebots, until the US guys started fighting about owned the rights to the concept, and that largely killed the televised stuff on both sides of the pond.
[01:01:07] <atom1> i wondered what happened to it
[01:01:17] <andypugh> Ours had twin 750W 24V motors. Peak current was something like 100A
[01:01:38] <atom1> stacked mosfets for controllers?
[01:03:00] <andypugh> It was a long time ago, and I didn't know half what I know now. We had off-the-shelf controllers, off-the-shelf radio control interfaces, and we didn't understand any of it
[01:03:16] <atom1> heh
[01:03:44] <andypugh> Nowadays, it would be all done by Arduinos, and we would have a stack of pre-programmed spares.
[01:05:22] <atom1> make some servos from the motors
[01:05:34] <andypugh> I expect the same is true of all the teams. There has been a huge change in the meantime. I reckon that a re-make of it would be a whole lot more interesting, as I assume that all the teams know far more too, and there is eBay now, for parts.
[01:06:01] <Jymmm> andypugh: stack of AVR's maybe =)
[01:06:29] <andypugh> Lots of options, including affordable on-robot intelligence.
[01:06:53] <Jymmm> nanobots!
[01:06:58] <andypugh> It's no big deal to have a $20 Arduino smashed up, it was a big deal to lose a $200 driver board.
[01:07:18] <Jymmm> where you finding $20 arduinos?
[01:07:29] <andypugh> Batteries have improved hugely in the interim too.

[01:10:15] <atom1> and a ft232
[01:10:19] <atom1> it appears
[01:10:32] <atom1> the rest is all software
[01:10:33] <andypugh> "Arduino" is an open source hardware platform.
[01:10:47] <Jymmm> andypugh: I know =)
[01:10:51] <atom1> heck, i have at least 3 eagle files for different ones
[01:11:16] <andypugh> Their "Film" version looks like fun
[01:11:17] <atom1> i'd rather make my own though
[01:11:55] <Jymmm> I have the Diecimila and paid about $40ish for it, just seemed strange that theres the same for half price is all
[01:12:11] <atom1> what chip does it have?
[01:12:25] <atom1> they use different avrs on em
[01:12:40] <atom1> i don't bother to keep track

[04:53:44] <atom1> The power supply voltage must be between 15VDC and 50VDC. The maximum power supply current required is 67% of the motorís rated phase current. An unregulated power supply may be used as long as the voltage stays between the limits; keep the ripple voltage to 10% or less for best results.

[14:14:22] <maddogma> Enable pin sounds like a possible culprit. Didn't see an option in Stepconfig. What's the syntax for enabling in Hal?
[14:15:37] <jcizek> What are you trying to enable?
[14:15:50] <maddogma> The enable pin
[14:17:46] <jcizek> I s that a HAL pin or an actual hardware pin?
[14:18:42] <jcizek> The stepconf wizzard does allow you to set "enable" as an option. It's one of the options in the dropdowns on the (2nd I believe) screen
[14:22:02] <maddogma> It's a hardware pin.
[14:23:10] <maddogma> If it helps, I'm using a CNC4PC C11G breakout board and 203v drivers.
[14:24:04] <jcizek> Check this out: http://linuxcnc.org/docs/html/config_stepper.html Look at section 1.3.6 Adding an enable signal. Is that what you are looking for?
[14:25:25] <maddogma> That's a big step in the right direction. Thank you!

[16:36:08] <Tom_itx> nice
[16:37:01] <Tom_itx> what spindle taper is that?
[16:37:14] <syyl> sk20
[16:37:15] <Tom_itx> (for size comparison)
[16:37:24] <syyl> uhm, should be int20
[16:37:41] <Tom_itx> nice small probe
[16:37:56] <Tom_itx> don't they make ir or wireless of some type too?
[16:38:01] <syyl> yeah
[16:38:07] <syyl> with infrared connection
[16:38:16] <Tom_itx> i think that's what we had on one of the okumas
[16:38:19] <syyl> even more expencive
[16:38:25] <Tom_itx> yeah i know
[16:38:31] <Tom_itx> what did that one set you back?
[16:38:51] <syyl> hm?
[16:38:55] <Tom_itx> cost
[16:38:59] <syyl> ah
[16:39:11] <syyl> around 4000eur
[16:39:22] <Tom_itx> they are nice though
[16:39:31] <syyl> without adaption to the cnc controller
[16:40:28] <syyl> wireless would have made no sense in our case, as the probe doesnt fit in the tool changer
[16:40:40] <Tom_itx> yeah
[16:40:57] <Tom_itx> this was a 50 taper with a big tool changer
[16:41:15] <Tom_itx> big belt rack on the backside
[16:41:17] <syyl> uh
[16:41:28] <syyl> 50 taper is a serious foot hazard when dropped
[16:41:50] <Tom_itx> there is a method to that
[16:42:09] <Tom_itx> see it coming, you lift your foot a bit to protect the tooling and no harm to the foot

[16:56:46] <jcizek> Tom_itx: just change the value of SCALE in your .ini file... if it's positive put a - in front, or vice versa

[16:57:49] <Tom_itx> ok
[16:58:05] <IchGuckLive> Hi all
[16:58:46] <jcizek> Tom: it
[16:58:58] <jcizek> Tom: it's possible in hal too, but it's easier in the .ini :)
[16:59:18] <Tom_itx> i just wondered what parameter to change
[16:59:26] <Tom_itx> i was looking in hal as well
[16:59:55] <jcizek> ya, changing the sign of SCALE is by far the easiest
[16:59:56] <Tom_itx> on the hostmot driver there's .invert_output
[17:00:31] <jcizek> you can use setp with an invert command in hal too, just do it where you assign the output pin
[17:00:46] <Tom_itx> the hostmot driver assigns those
[17:01:03] <jcizek> gotcha
[17:01:08] <Tom_itx> according to the .bit file i think
[17:01:31] <Tom_itx> otherwise it would be easy to find

[17:02:50] <jcizek> haha, i unnderstand
[17:02:52] <Tom_itx> but it would be nice to know how to do it in hal
[17:03:34] <Tom_itx> it kinda masks the fix when you go to look at it a year later

[17:04:09] <jcizek> yep understand. In hal it would look like this: setp parport.0.pin-01-out-invert 1
[17:04:39] <Tom_itx> so you just go for the io pin and invert it
[17:04:49] <Tom_itx> i can dmesg and find that easy enough
[17:05:50] <jcizek> yep, that should do it
[17:07:24] <Tom_itx> i just figured there would be a var assigned to it like: "setp hm2_[HOSTMOT2] (BOARD).0.stepgen.00.dirpin.invert_output" or some such thing
[17:08:02] -!- tlab has quit [Quit: Leaving]
[17:08:11] <jcizek> that i don't know since I dont' have a hostmot... but should be easy to look in there and see
[17:08:23] <jcizek> also, make sure you only invert the dir pin, not the step pin

[17:29:14] <IchGuckLive> you can mill this with a 1mm cutter
[17:29:35] <IchGuckLive> overall i try to mill all parts with a 1mm cutter
[17:29:38] <willburrrr2003> I generated my first g-code program lastnight . Started simple, face off part and set z0 , then turn the part from .635 down to .25 for .5 inch. the program worked nicely, but I have part deflection at the tip and it comes out about .26 instead of .25 there. the base of the cut is right at .25 . What can I do to deal with this deflection? I tried doing a finishing pass from .30 down to .25 taking half the cut I did the first t
[17:29:47] <Connor> Cool. I'm just about done hand wiring a prototype..
[17:29:58] <IchGuckLive> so the pendant can be done by every emc2 owner
[17:31:30] <IchGuckLive> Connor: also the routing is not handoptimized it must rout auto thats my line of scribitch
[17:32:07] <IchGuckLive> Connor: how is the switch part calt in Eng so i can name the var thisway
[17:32:20] <willburrrr2003> <ichguckLive? is there an off the shelf pendant that works with emc, or a buildable one shown on the web?

[17:33:12] <izua> are the pulse signals locked to eachother?
[17:33:55] <mrsunshine> hmm on this old lathe there is some koggs that slows down the spindle by half or something if i engage them, what can they be for ?
[17:34:01] <mrsunshine> its behind the actual spindle assembly
[17:34:09] <izua> for example, if the machine is executing a G1 X10 Y9, will there be two individual trains of pulses at with F1/F2 = 10/9 (or so), or will the faster one lead the frequency, and the slower on skip 1 step every 10 steps?
[17:34:15] <mrsunshine> not behind the spindle, to the side of it :P
[17:34:34] <izua> if so, is the last method safe, since it technically involves a lot of fast accs and deccs?
[17:34:49] <Connor> You have them called Axis and Increment
[17:35:04] <jcizek> JT- good morning! Having a hard time with your thcud.comp... it compiles with errors of a couple of hal_ini hal_exit hal_ etc... being undefined.

[17:38:02] <Connor> Oh yea. and no one way the '"right" way.
[17:38:17] <JT-Shop> jcizek: you did this? sudo apt-get build-dep emc2
[17:39:42] <JT-Shop> willburrrr2003: that has too many variables to really say, some options include a following rest, steady rest, tool post grinder or as you surmised put the part closer to the chuck
[17:39:56] <JT-Shop> depending on the material spring passes might help

[17:41:02] <willburrrr2003> <JT-Shop> material is ,forgive my spelling on this, Derlin plastic. What is a "spring pass"?
[17:41:26] <JT-Shop> a second or third cut and final diameter

[18:04:31] <jcizek> tom: the build-dep package i guess... i already have emc-dev and build-essential. They are appaarently not enough as I still get compile errors
[18:04:33] <JT-Hardinge> jcizek: http://wiki.linuxcnc.org/emcinfo.pl?ContributedComponents#How_to_compile_and_install_a_component
[18:05:01] <JT-Hardinge> First, install the emc2-dev (sudo apt-get install emc2-dev) and build-essential packages (sudo apt-get install build-essential).
[18:05:05] <IchGuckLive> but we can ad a mill mode by pressing one axis button -> move axis at serten speed till stop butten is pressd
[18:05:13] <JT-Hardinge> brb
[18:08:07] <jcizek> JT-Hardinge: Ya, I already have those packages installed, they are not apparetnly enough as I am still getting undefined declarations in JT-Shop's code while compiling

[18:30:20] <jcizek> Well, i found the lucid sources on linuxcnc.org (the 10.04 sources). There is no build-dep package in those either. I guess i'll have to download a Live-CD and see if it has different packages installed on it. It must.. I assum most of you guys must have installed your linux from a Live-cd with EMC already on it?

[18:34:07] <jcizek1> I installed from a network installation of ubuntu, then installed EMC with the install-emc2.sh script on the linuxcnc.org site. Apparently, they must not include the same things!

[20:45:27] <Poland_user> live cd kernel sucks
[20:45:42] <andypugh> There are dozens of us running the stock LiveCD install on the D510MO.
[20:46:10] <Poland_user> do you have cutsom kernel ??
[20:46:17] <andypugh> Fine, make your life hard than, but no matter what your opinion is of the kernel, it works, and yours doesn't/
[20:46:42] <Poland_user> do you have compiled kernel or genkernel ??
[20:47:15] <Poland_user> ??

[20:48:24] <andypugh> It's a kernel utitilty for allocating memory
[20:48:44] <andypugh> What hardware are you going to use?
[20:48:55] <Poland_user> LPT for now
[20:49:15] <Poland_user> itx D510MO mobo
[20:49:31] <andypugh> In that case, you don't need the 8i20 driver. You can just use the released EMC2 version (2.4.6, I think)
[20:50:07] <andypugh> Grab the liveCD image from the link I posted above. Install. Job done, no compiling, no making a custom kernel.
[20:50:29] <anonimasu> Poland_user: I seriously think you shouldnt say antyhing wether the sock kernel sucks when you cant get the realtime stuff compiled and your a gentoo user just my 5c
[20:50:34] <anonimasu> stock...
[20:50:42] <anonimasu> because that just shows your own ignorance to things
[20:50:52] <anonimasu> there's a guide in the wiki, it's not very extremely heavy to get it working
[20:51:19] <anonimasu> and if you can make statements that it sucks, well, i guess you are contributing to alt.kernel.dev reguarily...
[20:51:35] <anonimasu> ^_^
[20:52:25] <andypugh> Right guys, I am going to log off and dismantle my iMac to replace the hard drive. I am unlikely to be back soon, if at all....

[20:54:40] <Poland_user> just EMC2 compilation
[20:54:56] <Poland_user> I know that Live CD work
[20:55:00] <Poland_user> I have tested it
[20:55:02] <Poland_user> but
[20:55:13] <Poland_user> jitter is not so nice
[20:55:47] <Poland_user> I have read that when you compile kernel and emc from sourcec it will be better
[20:55:48] <FinboySlick> Poland_user: just so you know, don't expect graphics accel to fix your jitter.
[20:56:41] <Poland_user> maby rgaphic accel no but kernel compilation and emc cmpilation yes
[20:57:09] <FinboySlick> Poland_user: What's your max jitter as is?
[20:57:24] <Poland_user> about 9000
[20:57:34] <Poland_user> I have read 5000 is when you compile
[20:57:44] <FinboySlick> I started with 100 000 on my current box.
[20:58:01] <FinboySlick> I'm down to 4700.
[20:58:13] <anonimasu> Poland_user: that's a good neat jitter
[20:58:22] <FinboySlick> All I did was use a different network card, disabled a raid controller and generally tweaking the board.
[20:58:34] <Poland_user> have you made kernel compilation ?
[20:58:42] <FinboySlick> Poland_user: No.
[20:59:17] <Poland_user> ok, so what should I do to down jitter ?
[20:59:26] <Poland_user> I have disabel HT
[20:59:40] <FinboySlick> I'm a gentoo user. I'm typing this to you from a gentoo box, almost all my linux boxes are gentoo and I have a few production servers that are also gentoo. But I wouldn't run gentoo on something like my mill.
[20:59:46] <Poland_user> and I have one core isolated
[21:00:42] <anonimasu> I ran my cutting machine up to about 4m/min successfully with 10-11k jitter...
[21:01:02] <Poland_user> I like gentoo so I was thinking that it would be best solution
[21:01:09] <Poland_user> I have servos
[21:01:20] <Poland_user> 3000 RPM
[21:01:22] <elmo40> I have about 7000 jitter. my rig seems to run fine.
[21:01:23] <Poland_user> and encoder
[21:01:43] <anonimasu> you dont need alot less jitter for that kind of setup
[21:01:53] <Poland_user> max encoder resolution is 10 000
[21:01:53] <anonimasu> if you have a hardware counter(pico systems or mesa)
[21:02:10] <anonimasu> but dont expect anything without that kind of hardware to work out nicely
[21:02:13] <Poland_user> yes, I would like tobuy mesa card
[21:02:15] <Poland_user> 5i20
[21:02:18] <anonimasu> they work very good...

[21:02:49] <Poland_user> but for now I would like to try on LPT port
[21:02:52] <anonimasu> I dont know about their servo drives, but I have their 2kw ac drive that i'll hook up sometime next week or something
[21:02:58] <anonimasu> if time permits
[21:03:09] <anonimasu> and a small dc driver from them also, nicely sitting in a box
[21:03:14] <Poland_user> I have china servos
[21:03:16] <Poland_user> 1kW
[21:03:33] <Poland_user> STEP/DIR control
[21:03:46] <Poland_user> I have test it on linuxcnc live
[21:03:51] <Poland_user> and it work
[21:04:01] <Poland_user> but I have some random RTAI errors
[21:04:22] <Poland_user> maby I have setup jitter to hard
[21:05:02] <Poland_user> so I would like to get better jitter on compiled kernel
[21:05:29] <Poland_user> ok
[21:05:34] <Poland_user> I have question
[21:05:35] <anonimasu> I think JT-Shop has the same board as you
[21:06:13] <Poland_user> what jitter he has ?
[21:08:12] <anonimasu> stick around until he shows up
[21:08:59] <Poland_user> one moment I need to exit for 1 minute

[21:10:31] <Poland_user> I'm back
[21:11:13] <Poland_user> ok, so I have question
[21:11:27] <Poland_user> when I buy 5i20 mesa card
[21:11:38] <Poland_user> it would be running on LiveCD ??
[21:12:31] <Poland_user> or do I have to make some modification on Live distro ?
[21:13:33] * elmo40 does not understand the question...
[21:14:29] <Poland_user> 5i20 mesa card require kernel compilation or it will run on genkernel ??
[21:15:55] <anonimasu> it will run on the stock install
[21:16:57] <Poland_user> ok, so you are suggesting Live CD instalation and no compilation, is there any way to get the Live CD small ??
[21:17:06] <Poland_user> 1GB instalation ??
[21:18:59] <Poland_user> I have found 1GB very quick flashcard it's low cost
[21:19:26] <Poland_user> Can I put LiveCD to thise card ?
[21:23:34] <Poland_user> Ok, I have to go
[21:24:03] <Poland_user> Thank you very much for help, I think that I will try to LiveCD
[21:24:16] <Poland_user> maby you have right
[21:24:47] <Poland_user> and it is the better solution and pervormance is a matter os settings and mobo tweeks

[23:01:28] <andypugh-iPhone> So I am sat here like it's 1995 looking at XP textmode install screens.
[23:01:47] <jdhNC> boot the recovery console and do a fixmbr ?
[23:01:51] <jdhNC> or fix*
[23:02:25] <andypugh-iPhone> Yes, that would have been the going to do if I had half a clue about Winows.
[23:03:29] <andypugh-iPhone> Though I am concerned about the partition size. How big can FAT32 go?
[23:04:23] <jdhNC> big
[23:05:09] <jdhNC> why fat32?
[23:06:24] <andypugh-iPhone> That is the only Windows format that MacOS can create a partition with
