i am using tmc 2209s for the xyz and a tmc 2208 for the extruder, and i keep getting “Unable to read tmc uart ‘stepper_x’ register IFCNT” for the extruder and x axis, and probably the same for all of them.
I have a simillar setup at home, can sahre config files and photos. But one of the reasons for this problem could be that you have not supplied the 12-24v and the board is only powered by USB
it has 24v power, and i got the tmc2208 working, and the tmc2209s were in a board when it got shorted so im just gonna assume they are dead
the tmc2208 was just a weird size where only half the pins could connect, and i just bent the pins till it fit
Well my board had also shorted but the TMCs were file. None the less, I distinctily remeber I am not using the Fystec Drivers but BTT drivers, their UART pins are different. You need to connect a Jumper which will connect the BTT driver pin onto the board UART pin, the traditional BTT UART pin is connected to a Not-connected board pin in TMC2208/9 config on the F6
i tried that, im using some chinese brand drivers, but all the pins are the same other than the ones that go to the stepper but thats not whats causing the problem
also i had to use a solder bridge as there was no spot for a jumper on the driver
