Unable to read tmc uart 'stepper_x' register MSCNT #138

Hi everyone, I have an issue with my newly assembled printer. I have checked the connections multiple times and couldn't find any issues with the wiring. When I try to perform Home All or Home X/Y, I receive an error message after reaching the 0,0 position: Unable to read tmc uart 'stepper_x' register MSCNT sometimes: Unable to read tmc uart 'stepper_y' register MSCNT

I have already connected pins 4 and 5 on each driver, but it didn't help. Do you have any suggestions?

Printer is Voron 350 on Spider v3, S2209 v4, Orange Pi 4

Hello. Have almost the same issue here. Unable to read tmc uart 'stepper_z' register IFCNT

Were you able to solve it?

Safandula86 commented 1 year ago

Yes, please check jumpers under the stepper drivers

Kvis-Dev commented 1 year ago

My issue was different. Jumpers were fine, but I needed to solder a jumper between RX and TX pin on my drivers. See image below. Read the documentation to your drivers before doing this. image

Hey! I'm also having this issue. My spider 3.0 came with some jumpers under the stepper drivers (one jumper on each driver slot). I have tried the method you mention above but it has not worked either, which is weird because it is even mentioned on the spider wiki.

Any ideas? Anybody else had this issue? It is so annoying how little documentation there is around the 3.0 board.

It look like the issue comme from something bad in my TMC2209 driver since the trouble follow when swaped... I do not know how to : "increase the logging level for more detailed error messages by setting debug: true in the [tmc2209] section of your printer.cfg file." to "Use the QUERY_TMC command in the Klipper terminal to manually query the TMC 2209 driver registers. This can help diagnose whether the issue is with reading specific registers."
