Greetings,
I am having a problem with one of my printers, and am running up against a wall.
I had to replace my motherboard recently due to the heated bed circuitry failing.
I moved from a btt skr mini e3 v2.0 to a BTT SKR V1.3, with TMC 2130 Drivers. It is setup for sensorless homing and spi mode, and the m122 command comes back with spi communications working "correctly".
However, using pronterface the machine freezes and times out when I send any command to move the motors. It does respond to commands and gives feedback on tempature of the hotend and bed, and I can turn on and off the part cooling fans.
So, Im at a loss here, and don't know if its a driver issue, board issue, or software issue.
