General Mach Discussion / Re: Clearpath Servos are enabled, but wont move in Mach3

Fixed it! In case anyone else has this issue. The C-10 breakout board must have the COM jumper flipped.

General Mach Discussion / Clearpath Servos are enabled, but wont move in Mach3

« on: April 12, 2022, 11:45:55 PM »

I can't figure out what I am doing wrong.  I have a C-10 BOB with USB smoothstepper.  I'm using the standard cable from Teknic for the servos and verified my wires are pinned correctly inside my enclosure.

The LED on the servo is rapidly blinking green. I have my white and black wires connected to pins 2 and 3 and the yellow and brown wires connected to ground.

I connected the software to tune the motor and that worked fine, but nothing happens in Mach3.

I have tried changing several settings but I feel like I'm missing something and cannot seem to find a configuration guide for Mach3.

Any ideas?

Is the cutter pulling out the collet? Easy way to tell is mark a line with a sharpie and see if it moves.

General Mach Discussion / Re: 4th Axis jerky - Acceleration differences between A and XYZ?

« on: January 17, 2022, 03:40:14 PM »

It's still jerky, almost exactly the same. Fusion creates different feed rates, even if inverse time is not selected. I tried manually going through several lines and giving them the same feed rate, but its still the same results. I tried changing a bunch of settings from exact position to CV, editing CV paramters, changing the radius under the settings tab, but nothing seems to really affect the start/stop motion. It doesn't do that with 2D or 3D milling, but the 4th axis is causing some sort of hesitation.

Thanks! I'll give that a try.

It's per degree I guess? I know dimensionally everything is very dialed in.

That's probably a couple hundred lines of code. Some of the code is below.

General Mach Discussion / 4th Axis constantly pausing

« on: January 14, 2022, 10:53:35 PM »

Trying to figure out why my 4th axis isn't running smoothly. Every video I've seen shows people configuring the 4th axis and off it goes.

I've tried changing speeds, disabling backlash compensation, and changing several settings in mach3, but nothing seems to help.

I've look at the Gcode and there doesn't seem to be any particular pattern in the code and the pausing.

Any ideas?

General Mach Discussion / 4th Axis jerky - Acceleration differences between A and XYZ?

« on: March 22, 2021, 08:32:42 PM »

I've read a ton of posts trying to figure out why my 4th axis isn't smooth. I've eliminated smoothing (fusion 360 option), CV settings in Mach3, computer performance, disabled toolpaths to see if that helps. I think the issue is acceleration differences between A and the XYZ axes. My XYZ are set to 100 IPM, my 4th axis is set to 2500. If I set my A axis to 100 IPM its impossibly slow. Are there any tricks smooth this out?
