I spoke too soon regarding the stalls. It’s not consistent, but when running some jobs tonight the X-axis would bind from takeoff. I’ve tried running at 4500 and 4000 mm/min and still experienced the issue, so I may try bumping speeds back up and bring down the acceleration instead. I’ll also try setting zero a foot out or so and see if it’s just the start of the axis.
I’m still of the opinion that it’s my setup that needs tweaking, but might as well get some testing in while I wait.
