TMC2208 UART problem
lucasgomezortiz opened this issue · 6 comments
How about, I have a sgen l board and some tmc2208 from the manufacturer geeetech. I can't put the uart mode with the tmc, it marks me "connection error" I followed the steps described here but I can't make them work, in standalone mode they work without problem.
If I have doubts, the github guide does not say anything about putting any jumper on the X-uart connectors
Here I leave what the pronterface gives me when I enter M122

Something I forgot to clear these up using the Marlin version bugfix-2.0.x
Hi! Can you provide your tmc2208 picture and your buy it link to me, i will try to and how to use it.

This is the tmc, also something that I notice with this manufacturer, that the colors do not correspond to the position, if I look for DIR in the MKS it is inverted with respect to the guide colors that the TMCs have
Blue (tmc) --- Black (board)
Black (tmc) --- Green (board)
Ok! You need setting it
- MKS SGEN_L motherboard setting UART mode and use jumpers
- Connect PDN-UART to pin4

sorry for the delay in answering, just these days I started to check the printer, I already made the short but it still does not work, "TMC CONNECTION ERROR"
