Hello!
I am working in a college shop where we have three Syil X4 mills for student use. I am in the process of upgrading one to use a 'leafboy77' USB Motion control card. I have everything working thus far, but need some help with the spindle auto calibrate (autocal). The auto calibration works, but either because of noise or the USB board I get 'spikes' in the calibration line, due to the fact the rpm reading will spike occasionally or read zero breifly. This will cause the spindle to either run much faster or much slower when commanded at certain speeds.
Because it works otherwise, I would really just like to be able to edit the calibration curve, there is usually only 3-4 spikes to edit. Is there a way to do this?
Otherwise it works perfectly.
Thanks!
Nick
