For a US company selling these at a pretty good markup they still use a crappy parallel port controller with Mach3 software. It's just junk.
This will be my first machine with dual drivers for the Y axis and auto squaring. It currently has Leadshine M860 drives and some wimpy power supplies. It's already been retrofit once with a smoothstepper and it was a poor job at best. None of the limit switches are hooked up, the VFD is manual control and there's no tool touch of plate. It has 2 proximity sensors on each axis and it uses very nice shielded wire just about everywhere. I have not removed the motor covers yet to get any data on them or the VFD. It has rack and pinion drives on all axis. It's a really stout machine with mediocre electronics at best. Time for an Acorn.

I searched the forum for info on the Leadshine M860 drives and find only one post with only a mention of this drive. The owner would like to just upgrade the controller and software and wire it up so everything works and add a touch off plate and spindle control. It also has a vacuum table that we can control.
I looked through the schematics from Acorn and find no M860 drive diagrams. I assumed it wires to the DB25 like my current machine is wired with different leadshine drives. Although, reading the drive manual, found here, http://www.leadshine.com/UploadFile/Down/M860m.pdf, they can be controlled with 5, 12 or 24 volts depending on some jumper settings with some added resistors on the voltage lines. This leads me to believe they can wire up to the screw terminals on the Acorn using 24 volts. No?
I'm starting a list of parts and supplies needed to get this party started, looking forward to yet another Acorn conversion.
