E and Z axis TMC config issue #4

Closed The-Synthax closed 9 months ago

The-Synthax commented 1 year ago

For some reason, stepper drivers for E and Z aren't responding appropriately to serial commands. The result of this is no response to setting changes such as microstepping, motor current, stealthchop, spread cycle, etc. In practical terms, this means that the extruder has a lack of torque (causing the infamous "clicking" extruder these printers are known for) and both E and Z steppers run hotter than normal. I don't currently know if this is a hardware issue, or if this problem effects a stock printer. If so, this would explain the extruder skipping steps that the Voxel and Adventurer are plagued with.

TODO: probe serial trace to determine where my serial packets are getting lost. Is the muxing wrong? There should be a serial communications error if there's no communication at all, and changing pin muxing does indeed trigger this error, so it at least thinks it's communicating with the drivers. Enabling UART address throws an error, for some reason. More testing required.
