I have a Flipsky 7070 v2 motor running on a 24v 600W Meanwell power supply. It is using the internall hall sensors at the moment but I have an encoder I will print a mount for later. It passes calibration but runs rough, the topic of another post.
For this post I report and ask about position mode. If I switch it to control position, the first instant I touch the slider the motor kicks and turns off. Not sure where to start here. Any suggestions?
Thanks!
Responded to the other post!
Guessing this is just an issue with the pos_gain tuning (try setting pos_gain lower). As bad as hall sensors are for low-speed velocity control, they’re even worse for position control. You can get some semblance of control with tuning, though may not be worth it. I’m guessing the S1 is throwing some error that you can see in the bottom left corner – what error is it?
That being said, if you already have an encoder (which encoder?), I’d recommend just getting that connected and wired up.
I am thinking based on my experience and your comment, that position control with hall sensors on this motor is impossible. I don’t think it’s even worth testing more since I already had the pos_gain at the lowest setting and the motor practically jumped off of the bench in the first instant and failed with errors. There’s nothing to test! Thanks for the info on the other thread. I will keep after this - it’s a project I have been wanting to build for many years, finally have some hardware and momentum making it. Glad to have a community around with helpful folks such as yourself.

Maybe not impossible, but likely not worth your time

It sounds like a cool project!! Here to help any way I can.
