Hello! I need some guidance with getting the 8i20 drive running. I have pins connected according to PCWs suggestion here: https://forum.linuxcnc.org/27-driver-boards/45241-8i20#236124
BLDC component is loaded with "cfg=qi" If I setp bldc.0.init to 1, motor does move a little and initdone also goes to 1 making me think that it did see the encoder index. But I cannot get the motor to turn (the belt is removed, it is disconnected from machine) by jogging the axis, I cannot get it to move if I setp pid.command to particular value. I believe that I need to specify encoder-offset parameter, but I do not understand how exactly encoder-offset value for BLDC component is calculated. What would be the recommended sequence to get the motor moving? For example, first step - setp 8i20.angle and current pins to particular values? Then connect them to bldc and setp bldc.0.value? I tried this, does not work at the moment. Hopefully because of wrong encoder-offset. And then I hopefully will reach a point where PID will have to tuned. What is current status of PID autotuning? I know that there is at-pid (or something like that) component but I am not sure. Is it worth trying? Thanks in advance!
