Z_move_comp message problem

Hello,
We use our 3D printer every day but met a random problem for some time.

Randomly, the printer stops in the middle of a print.
When we look in the status of NanoDlp, each time the bug appears, it has marked this:
- Received Data From Controller: Z_move5)ok

It is as if there was a serial communication problem between the raspberry and the NanoDLP Controller Board.

Normally there should be marked in 2 lines:
- Received Data From Controller: ok
- Data From Controller: Z_move_comp

This is quite a strange problem because we have 3 identical printers (hardware + software) and the bug only appears on 1 of the 3.

We also checked the wiring.

Does someone have an idea ?

Thanks in advance
Jean

Re: Z_move_comp message problem

You are right it is communication issue that may caused by

* Cable issue
* Power issue
