Z Axis issues with X-50

[prfiredog (Joseph Rivera)]

Let me start by saying my machine has always worked fine.

I recently reset the system to show the journeyman extension and set the firmware to the x-50 settings. I also updated the firmware for the first time ever.

Now my controller will not jog the z axis consistently and sometimes its backwards. Also, after I set the z-axis home, and begin a carve, the z axis is way up off the material like it was never set.

Any ideas on what I need to do?

I have disconnected it all, unplugged it, let it sit and put it back together and still the same.

I’m at a loss.

Hey Joseph,

@prfiredog

sometimes its backwards

@OnefinityCNC

If your z moves in the opposite direction than what it’s told to do, disregard the first two steps as it is ALWAYS a wire/connection issue. Check this link for more info: Troubleshooting: Rail is getting hung, stuck, or out of alignment (x35/x50 machines)

@Aiph5u

there can be many causes for loosing steps. EMI is one of them. I noticed the PwnCNC VFD housing is neither made of metal nor is the VFD enclosed into a steel control cabinet, despite the fact that a VFD is a device intended to be installed in a VFD control cabinet (which serves as faraday cage ). Also all Onefinity cables are not shielded. In industry, all motor and signal cables of a CNC machine are shielded and grounded to prevent EMI.

Have you searched for Z plunge issue in this forum?
