TMC 2240 UNDERVOLTAGE #96

Open greggs12 opened 4 months ago

greggs12 commented 4 months ago

whenever I try homing I get the error: TMC 'stepper_z' reports error: GSTAT: 0000001d reset=1(Reset) uv_cp=1(Undervoltage!) I know it's not actually a problem with voltage as I have checked

I removed blue driver heatsink on toolhead and undervoltage error disappeared.

Look at ticket #28, quite related to yours.

Since the error is triggered by stepper_z, it could maybe confirm that the ESD issue can also appear on the motherboard, but can also be due to bad cabling, or bad power supply, etc.
