Swapping Out Stepper Drivers on LongBoard CNC Controller


I recently started helping a friend who bought a LongMill Mk2. We’re working on some fairly complex projects where I would like to not have to worry about skipping steps, but also don’t want to slow the machine down and have to wait 2-3 hours for an op to finish. I have a decent amount of experience soldering and altering firmware, so I was wondering if it would be possible to swap out the stepper drivers on the LongBoard controller for a closed loop stepper driver.

Edit: Specified LongMill instead of LongBoard

Welcome Andrew. I can’t really help with your question but I’m a little confused as to which LongBoard you have. As far as I know the Mk2 ships with the regular LongBoard, the same one the Mk1 LongMill used. But now Sienci has the SuperLongBoard and I’m not sure if that’s what you meant by LongBoard Mk2

I’m not sure if it makes a difference in answering but it might.

Hi Michael,

I’m using the LongBoard, not SuperLongBoard. Sorry, I think I mixed up some of the nomenclature. I’m using the LongMill Mk2.

No problem, I just thought that if I was confused maybe someone that does know how to help you would be too. Thanks for clearing up the waters and I hope that someone else can help you. Unfortunately the subject is outside my skill set.
