Right i will do that for the next build.  I found an old xbox in the shed and decided it was just the right size!  Everything fits and has good ventilation due to being a gaming console.  I will be fitting some fans on the case to give some through air.

The bit  of mdf is temporary lol

There is movement!  The steppers are wired up and behaving correctly, I think!  The little one is getting a bit warm at idle.  Can still handle it but I'm worried Iv done something wrong

Perfectly normal. As long as you can keep your hand on them for a few seconds, they'll be fine.

Thanks MC

Was i correct to wire the motors in series, since im using a 36v supply and running the motors at 1.5A.  i can see if they will take 2A later but they are only 1A per phase i think

Also does anyone have the XML configuration file for one of these lathes for Mach3?

Have a question for you MC

Would this spindle board be suitable to use with a KBIC controller?

Unless someone has an identical setup to you then a xml from them will not be any use. They would have to be using the same motors/drives and have the I/O connected to the same pins.

Yes. It's all optoisolated with a built in DC/DC power supply, so it'll do the job nicely.

Long time since i last updated.  I managed to get the lathe working nicely (still no spindle control via mach3).  Having fun using it for prototype work and have converted another machine since to the same spec.

I now have another Conect lathe with a toolchanger that i will be converting but there are a few things i still have to figure out.  ill start a new build diary with this machine (will probably need your help again Hood!
