MKS GenL1 with TMC2130 SPI mode switch problem
Using 1 means full step which is very rough and may cause resonance. Are you sure the DEC axis is not emitting a high pitched sound when it is not moving? If it does, then it is stalling, and you need

STM32 and Skysafari goto setup
With the parameters I mentioned before (400, 64, 1, 36), the STM32 can do 3.75 deg/secs slewing at Fastest setting. That is without MICROSTEPS_GOTO. If you use that, and set it to 4 or 8, you will be

STM32 stepper motors won't move
Oh, I didn't mean to say that 24V is not good. It is better of course. But the point was whether 12V will work at all or not. It does, and in this case where things are not working, it is better not t

Good plan. The LV8729 should work if you configure Vref to output 50% of the 1.68A current. Do you have WiFi? If so, do you have Android? If yes, then you don't need an SHC, at least initially until y

Nothing will blow up regarding the TMC2209. But you may get unexpected results (set to a certain microstepping and/or steps per degree, and actually get different ones).

Great result Jamie ... and thanks for the report. Is that the same Rowan modded EQ6 that you reported on earlier? Same 200 step motors with 47/12 gear reduction? Only change is MKS v2.1 and TMC2209?

It is better to add something like this in OnStep.ino near the DEBUG setting: "Use ON or VERBOSE only if you are explicitly instructed to do so by Howard" And the same for the WiFi.ino DEBUG as well .

Now your STM32 and Wemos are both working fine. For your Losmandy, we need to know how you connected the motors to the worm shaft. Is it direct or via pulleys? If pulleys, what are the number of teeth
