Hello.. I have a strange issue.. When i connect the skr 1.3 via USB the PC detects and the microSD appears and everything works ok... When i connect 24v i loose comunication with the pc... But.. If i press the reset button.. The USB works again... The board only works when i press the reset button.... But... After 1m ou so.. The board loose comunication again...

Hardware fault??

I quit this board... Put original firmware.. Connect the USB cable and 24v power supply.. Loose connection with the pc... Connect only USB with lcd2004 and original firmware...

Appears: TMC CONNECTION ERROR...?????

Without doing nothing.... Without doind any changes in marlin....

I quit this

There is a jumper near the middle of the board that says INT +5v USB. When powering with your Power supply (not usb) make sure the jumper is on the INT side.

I tried both ways and nothing...

Have you had the board up and running already once? Or is this a new experience? What stepper drivers are you using?

Also, when testing, do you have heat sensors attached? When I just got the board, I got crazy that the board stopped working after starting up, and it was because I had a test setup, but no temperature sensors attached so it shut down because of no temperature reading.

The board only worked or by usb to access sdcard or by 24v to really work... There is a component that is dead.. Waiting for it to swap to see if the problem is from that or is really dead the board... The component is: MC74HCT125ADTR2G

The stepper driver is tmc2208 uart v1.2 from fysetc
