After a couple issues - First cuts - success - LowRider CNC / Troubleshooting - V1E.com Forum and an oddity last night - I attempted to cut a section of a sturt plate and ended up cutting waaay too deep (almost 9mm into the spoil board), a better outcome tonight…
Checked it for accuracy and it’s pretty good - to within 0.1-0.2mm, which even with a digital vernier I’m not sure I measure much more accurately with, I think means I’m good to go cut the strut plates!
