Duet 3 6HC and setting up Stealthchop
-
Anyone setup a command to calibrate and start Stealthchop on Duet 3 to add to a Homing command?
Printer is loudest in the room and would like to get it to swap to Stealth mode...but read I need to calibrate it with pauses and motion.
-
From my understanding the drivers are self calibrating and the only motion needed is achieved during homing itself.
Have you tried to set the drivers to stealthchop yet?
-
I have, but there is a sequence that is needed after setting Stealthchop to make it calibrate the back emf. let me see if I can find the post from dc42

@dc42 said in Duet 3 Mini 5+ sensorless homing configuration:
Bear in mind that you need to execute a tuning procedure when using stealthChop mode.
-
Yes, and if we look at the data sheet for the driver here is what they say about calibration.

7.1 Automatic Tuning StealthChop2 integrates an automatic tuning procedure (AT), which adapts the most important operating parameters to the motor automatically. This way, StealthChop2 allows high motor dynamics and supports powering down the motor to very low currents. Just two steps have to be respected by the motion controller for best results: Start with the motor in standstill, but powered with nominal run current (AT#1). Move the motor at a medium velocity, e.g. as part of a homing procedure (AT#2).
