CNC Sewing machine question

Do you need to be able to alter the relative phase?
If not, then a PID controller with feedback from the slave motor position, and command directly from the master motor encoder position will do what you want.

Master encoder will run in velocity control mode, and slave will run in step control mode, i am preparing test setup.

In PID mode you would need to have the slave run in velocity mode too.

I am having trouble with connecting general mechatronics axis dac, can anybody help me by giving instructions?

When i plug gm axis dac, linuxcnc enters estop mode and can not lift up estop button from axis gui, why this may happen?

This sounds like you might have a wiring fault that is pulling down one of your control voltages.

I have never used General Mechatronics, so this is speculation.

What are you trying to control with the DAC?

I want to run motor in velocity control mode, So i was thinking the gm axis dac may help.
