Hey everyone. Quick question. I double checked my current settings as I was told that this could cause some of the problem. I reduced the current and the issue improved, it didn't go away but was definitely better. The downside is that performance, in terms of speed, drastically reduced.

At the original current setting, with 32x micro stepping, I could move the slider very fast, I'm afraid I can't quantify that as I'm not sure how to measure it but with no payload I couldn't really get it to stall. At least, I got to a point where it was far faster then I'd ever need and stopped. With the slightly lower current setting it stalls very easily. Again, this is hard to quantify but not very fast.

This video shows how fast it could move at the higher current setting - https://drive.google.com/file/d/17A-...ew?usp=sharing

I'd estimate that at the lower current setting it can move at maybe 1/6th of this speed.

This is the info for the stepper motor - https://drive.google.com/file/d/1rhc...ew?usp=sharing - if that link ever breaks the model is FM86128SJT03 - it's rated at 3 amps.

I originally had it set to 3.2A (RMS) and 4.5A (peak) on the driver. I tested it quite a lot at this setting and the motor barley got warm so I thought this was ok. The next setting down is 2.2A (RMS) and 3.1A (peak). That lower setting is where the performance drops off.

Did I have the current set too high?
