One Trinamic TMC2209 driver chip has stopped working. It happened suddenly, after about 1 month of normal operation.
Even though the chip is still communicating (tested with 'M122' - TMC Debugging Marlin's code), but the motor does not even move. Rewiring or switching to another stepper motor did not help. But the remapping (in Marlin firmware) of broken channel to another free channel (E1 channel e.g.) works well. This confirms this is not software problem, problem is the broken TMC2209 chip.
First symptoms
During 1 month of operation, it sometimes happened (after the printing restart) that the mother board got to a state when the drivers did not remember their settings and had to be reset manually. After the board reset it worked normally again.
It sometimes happened to me (but not during the printing) that the board seemed to react to 'an ESD event'. When touching the grounded frame of the printer, the motors (or one of the motors) jerked suddenly, and with the subsequent 'home' command the motor moved away in unpredictable direction and speed, also the driver did not respond to the software limit switches (StallGuard function in TMC2209).
Subsequently, I read the content of the TMC's registers ('M122' Marlin's command) and I found that drivers were set to their defaut factory settings. This proves the fact that an internal reset has occurred in the TMC. Only after the board reset the firmware restored the correct registry settings.
My setting:
Anet A8 Plus printer (24V)
shielded case box
grounded printer framework
max. driver curent 800 mA
hold curent 300 mA
original heat sinks
StallGuard X/Y-endstop mode
I bought BTT SKR E3 Turbo directly from https://www.biqu.equipment just about 2 months ago. But product page does not exist today (it points to another product) ...
BIQU did not responded to my requests yet.
BTW:
Recently I bought 2 pieces of new Biqu H2 V3 extruder for my 3D printers, from the same eshop. And I must say that I am extremely satisfied with them, I've never run a better extruder before. Unfortunately, the mentioned board is probably a big disappointment for me.
