TMC2208 UART problem #45

Closed lucasgomezortiz closed 3 years ago

lucasgomezortiz commented 3 years ago

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

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) image

Ok! You need setting it

  1. MKS SGEN_L motherboard setting UART mode and use jumpers image
  2. Connect PDN-UART to pin4 image

@lucasgomezortiz Hi! It is will working?

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"
