General Mach Discussion / Re: Z Axis Stopped Movement

« on: October 15, 2014, 02:53:53 AM »

I noticed when I tried to move the Z axis a few minutes ago, there is an audible noise when I press page up and page down, so it appears the motor is still getting electricity, but the head is not moving. I may have to remove the back shield and see if the motor is trying to turn. Do you guys have any troubleshooting tricks I should try?

General Mach Discussion / Z Axis Stopped Movement

« on: October 14, 2014, 09:49:44 PM »

I was running a program and everything was working well. I was cutting a deep pocket and the Z axis suddenly quit moving. Both X and Y work. When I home all, the Z axis DRO counts down, but the axis does not move. I can home X and Y with no problem. Is this a wiring problem?

I will keep that in mind. Thanks.

That seems to have fixed the problem. All axis move in fast jog with no hesitation. Thank you very much.

Where is backlash? I don't see it in general config. The shuttle accel is set on 1

Hood,
I changed to CV, but it still happens when I rapid jog. Could it be a motor tuning problem?

When I jog and when it feeds during the program run, the motors accelerate to speed and then almost immediately, the motor decelerates to a quick stop, and then accelerates back up to speed. This happens each time the axis changes direction or begins the initial movement. How do I insert the xml file?

I have the latest free upgrade version.
