I have my Snapmaker for some weeks now and now tried using the Carving head (after some 3D printing and very little Laser engraving).
I cutted some names into Lego Bricks (nice thing on thingiverse for this) and also tried it into wood.
Now, after some hours trying the CNC carving head stopped spinning. Or in more detail. It is spinning very slowly for some seconds and than stops. After this, also most of the functions related to the cutting head aren’t working anymore (restart the spindle. Or starting a new cutting from file. If I do so, nothing happens). So I assume some failure protection in software?
When I try to rotate the spindle by hand it runs quite easyly and free. Not totally, but I assume, the motor itself is also generating some resistance itself (it feels exactly like this). It is only very little resistance.
I connected the printer to USB and tried starting the spindle from SnapmakerJS (was using carving from USB-Stick files before) and the output in the console showed:
M3 ok Error:MAXTEMP triggered, system stopped! Error:Printer halted. kill() called! other < Err: MAXTEMP
What should I do? Of course I tried switching it on and off already (doesn’t really help, it is only “resetting” the some second slow spinning). I could open the CNC carving head, no problem, but I do not know what to look for (would need some guidance for this). Everything seems alright from the outside, actually nothing looks broken (or smells broken, you know like cooked electronics) perhaps I only do a mistake (but I do not think so, because I have done multiple carvings already).
PS: BTW it would be great if it would be possible to copy the content of the console in SnapmakerJS! I had to rewrite the Error by myself, because I couldn’t copy & paste it This would make failure reports much easier in the future (and more failure tolerant. Now I could have written down something wrong. I double checked )
