Jogging issues on DC motors with incremental encoders #103

Open ZLLentz opened 4 years ago

ZLLentz commented 4 years ago

From Bill Schlotter on slack: "I just went to Jog the focus on IM1L0. It was at -8% and I had the jog set to 2.0. I pressed the right jog button and the motor went immediatly to fifty some % and then ended up at 23%. The image went way way out of focus so I know it moved more than 2. This might reproduce on the Zoom....which I haven't and don't need to adjust. Please let me know if you want to try to reproduce this. (We need to get this fixed -- same thing happened coming up from the last PAMM)"
