I recently bought a well-used Shapeoko 3 Sparkfun edition from a local makerspace. I finally finished rebuilding it with the parts kit I ordered, and it seems to be working! However, there is a weird, sort of chugging noise on every axis when I jog it.

Since it is every axis, I figure it must be something to do with the settings. As seen here: Stepoko: Powered by grbl Hookup Guide - SparkFun Learn on the official Sparkfun guide for the board that this machine has, all of the settings on my machine are as listed on this page.
Small update: got it working! It definitely was just the tiny steps causing that noise. Whoops. The homing switches are working now, too.
The Z-axis belt had slipped off the wheel at the bottom, but I fixed got that back on and snugged it up with the pulley on the motor shaft, and it’s real solid now.
Haven’t figured out the weird “rub” noise on the y-axis, but it doesn’t seem to happen during actual use. Finally cut out some test pieces and it seems super accurate. Excited to be able to start pumping out parts! Now to decide what to make…
