General Mach Discussion / Re: Setting up a second machine

« on: November 01, 2008, 08:29:17 PM »

I set up another profile and can now set the motor tune how it needs to be. Now for the next question, has anyone out there set up Mach with the Phelps CNC Argon servo drive? I can get everything to power up but can't get the motors to respond to the commands I'm sending. I took the cable from the xylotex board that was running my stepper motors on my taig so I know those settings work. I think the step/ direction pulses are being received as the motor dithering slows when I send a command to move, but the motor won't make any movement beyond calming the dithering. Thanks for the help.

thanks poppabear, that is exactly what I need. Now, can the motors be tuned in each of the profiles?

I've been trying to set up a cnc lathe running the mach3 program and have run into a problem. I can't seem to find where to tune the motors for the second machine. I've been running Mach 3 for two years on a Taig mill using stepper motors and a xylotex drive system. The new system uses servo motors and Phelps argon servo drives. Are the motor tuning settings for Mach3 global or is there a way to tune the second set of motors separately?

Thanks again for the info. The tachs are brushed and I have verified an output voltage when turned by hand. I'll have to take care of that prior to installation.

Thanks for the input. The L298 is a chip for assembling a driver and I have yet to find out if it has feedback capability. I think I might end up assembling a couple of the UHU controllers and two of the L298 drivers for the axes in the end product. This is totally new territory for me as I am building the lathe from the ground up and all of the electronics on the side. It's a rather ambitious undertaking but hey why not. Dave: what did you mean by spoiling a good job half way through with the tachs?

Hello all. I've been running Mach for almost two years now on a Taig mill and I love it. I recently decided to attempt a build for a small, high precision lathe using Kollmorgen ServoDisc motors. The motors are equipped with a tach and an encoder currently. They are low torque motors which is acceptable for the setup. My question is: will a basic L298 based driver work with this setup or will a feedback loop be necessary on the servo driver?
