200W CNC auto-pauses second into an operation

Snapmaker 2.0
1

I’ve been using my new 200W CNC on the snapmaker 2.0 for a few weeks, but it has recently stopped working. When I execute an operation it loads the gcode and begins to carve but pauses itself (not at my command) within the first minute or so. See the first attached image. When I press the “resume” button on the touch screen it gives an error message: “Unable to resume job. Please check your machine settings and try again.” See the second attached image.

What can I do to fix this or even start to troubleshoot?

Door switch?

Export your logs and let us have a look about.
If the tool gets blocked the issue appears the same.

I think it is triggering the “tool blocked” case incorrectly. I experimented by raising the z offset a bit so it wouldn’t engage the stock. This ran fine until it came to a point where the tool brushed against the stock (but wasn’t removing any material). The moment the tool touched the machine paused.

I’m at work but I should be able to export logs when I get home this evening. That is something I do on the touch screen? Are the logs saved to the USB stick?

Yes, Export via Touchscreen and exported to a USB stick, it takes a while so click export and wait until the message it’s exported.

Following up here in case anyone else sees this issue:

I contacted snapmaker support and after a few rounds of debugging (sending them logs etc) they concluded that there was a fault in the control board and sent me a new one. I was able to do the swap myself and it did solve my problem.

As it stands in the new gcode wiki, you should be able to readout the current state/error of the toolhead with M1006:
