Nothing seems to fix the rather random problem.
- I lowered the currents (maybe it overheats...). No change, but I'll leave it low as the machine moves nicely.
- I changed from 16 to 8 microsteps (BTW, you don't need the jumpers. You can leave them off and define the microsteps in the configuration_adv.h. And off course correct the steps / mm in the configuration.h) I hoped it would make the processor less busy.
- I tried disabling stealth chop, more noise no solution. Turned it back on.
- I tried disabling TMC_DEBUG (M122) no solution, turned it back on.
I'm at a loss, now, the enabling is set to true fairly randomly, from not starting Z-probing on G28 to completely finishing G29. Somewhere in between it changes Z enabling to true which stops it. And E enabling is set to true (starts at false as it should be at startup) at any random move.
I am considering replacing Z and E with 4988s, just to be done with it. But I think this should work, somehow. I am not the first to use these things, right?
Cheers,
