Motor collision error on AR3...
Hello,
I purchased the AR3 kit a few months ago, along with a Teensy 4.1 and CUI AMT103-V encoders from Arrow Electronics.
When I try to run the motors individually with the encoders connected, I consistently encounter a “motor collision” error. I am using the AR4 HMI Interface 3.0 software (.exe).
I should also mention that I was unable to source the Molex connectors in my country, so I used jumper wires for the connections instead.
I would appreciate any suggestions or insights on what might be causing this issue.
Thank you.
Granted I only have J1..J3 fabricated and wired but what I did is set the encoder for 1000 pulses per rev which is 4000 edges per rev.
I also configured the AR3 StepperOnLine AR3 drivers to match the AR4 settings:
Now I can use the most recent AR4 software without worrying about changing parameters in the code. When I ask J1..J3 to move a specific distance it moves the correct amount.
You will have to home each axis to avoid those motor collision errors. Even if you just hook up a switch and tell it to calibrate only that axis and then press the switch.
