Encoder for rotary Axis.

Hi @masso-support

Im just about to start converting a rotary table to be my 4th axis. Is it possible for the Masso to use a encoder for precise positioning & homing?


Thanks in advance


Hi @ethan-downey

Masso doesn't support rotary encoder in 4th axis mode. A stepper motor should be very accurate once you have it geared down though.



it seems Masso doesn't support a lot of normal CNC functions.

Are they planned for the future or should I just get a real CNC controller?

Hi ecgworks

The way MASSO uses a rotary encoder on the 4th axis is for the encoder to be connected to the motor and the drive monitors the motor position and signals MASSO if there is a positional error at which time MASSO enters feed hold while the issue is sorted. There seems to be very little point in using processing power to manage something that a Servo or Hybrid stepper drive is designed to do automatically.
Homing for the axis is provided in the form of homing sensors.
