Managed to square up the waveform for the step at the expense of halving it’s max frequency🤦‍♂️ But I’ve changed the driver board for the version that actually has half step input so my new max speed is about 3sec/rev which looks ok I think. It’s slmost working how I want it but I need to figure out how to shape the response as it’s too long in the very slow movement then suddenly shoots off into high speed- not sure why as the step times should be linear from the pot 🤷‍♂️ Needs some thought
