Makerbase SERVOxxD Closed loop Stepper Motor Example1 PC Control Software example 

What is the max range when returning to zero after power on? Is it just 0-360° range when finding zero, could it be 0-36000°? since I'm planing to use gearbox on the motor. Thanks

It seems that servo42D does not support 0.9 degree steppers, contrary to what the Aliexpress Makerbase Official Store claimed. Is there a firmware upgrade that can fix this?

Can I control the 485 model trough modbus? If so, how? Would be very nice if I could control it trough a HMI on modbus protocol.

Very nice product! Where can we find to download the MKS ServoD Control v1.0.3 software please?

Is there a version that works also with the CAN interface? Not like the low level Cangaroo?

I just received two of these boards. Unfortunately could not test yet since calibration throws a Reverse Lookup Error. Rotor spins, and I tried adjusting magnet distance to the PCB, but calibration fails. What could be wrong?
