Hello,
I have MKS SERVO42C for my stepper motors. The basic part is working fine.
Is there any way to read the hall sensor encoder's data into an Arduino for positioning?

you would need to check the schematic of how the encoder is wired?
but what I understand, the driver has its own firmware and microcontroller so it is up to that whether the position data is being sent out?

It can communicate with UART to the board. I try to use an old CNC machine electronics (Ramps board on a MEGA) for a motorised throttle quadrant and it would be good if it can be converted.

seems it supports some type of serial output, not directly supported by MobiFlight I am afraid.
I guess the position sensing is used internally by the driver?
ashen arch
ramps would use those like regular stepper drivers I guess, not as servo?
I mean you can use the ramps with MF when you just set correct pins for steppers and the fets
but the encoder likely is not wired so that it can be just directly read

This is for not to lose steps, so basically a pretty good feature with a good positioning
ashen arch
yea
you could use the throttle pots (or set up hall sensors for better accuracy) to read position
it's kinda silly when there are the encoders too
but it should still work

Pots are pretty bad IMO since they can wear out. I'm thinking about normal hall sensors but since I have these boards with similar sensors I thought I can save it.

For the hall sensors if thiss can't work
ashen arch
yeah it would be cool, but I fear if they are just wired for the stepper drivers

But the best could be to get the data somehow from the UART comm for the sensors.

yeah, the firmware of the mks is open source
maybe check if there is some way to output position?

Sadly I'm more like a HW guy than a software guy 😦
