I worked on LRCNC build for the past several days. When I came to upload the firmware it results in an error, and when I click build it successfully. Here a screenshot from platformIO:
The skr is probably flashed (people should be flashing via the sd card in 99.9% of the cases). You need to flash the screen and then make sure the baud rate is set to 250k
You also need to use the correct data cables. When using touch screen mode you need to use the single 5pin (usually black) cable that plugs into the (IIRC) rs232 port on the skr. The two grey cables are only used when you want to use marlin mode on the display.
One of those ribbons is also used for the tft sdcard if available (aux2). +1 what Jeff said about flashing the tft. I forgot I just had to do the same thing setting up my Gtr board.
When I test some gcode to see stepper motors movement I notice slight noise when I pause the process. is that cause due to the stepper driver or it is normal.
My board came with TMC2208 drivers, is it ok or should I get TMC2209 driver instead?
