I’m back in action…
New parts are working well, I keep finding more cracked parts which is a little upsetting. The router clamp is currently just some straps of 2mm steel.
Turns out the big issue wasn’t the cracked parts, instead it was that one stepper motor wasn’t holding torque (or working at all? It’s hard to figure out with my rather short X Axis)
This person seemed to have a similar problem; One stepper not holding when still - #10 by jeffeb3
It turned out to be the driver - I keep poaching the drivers from this machine for other projects, replaced the TMC2209 and its now happy as Larry.
