Fixing limit switch clearing and sloppy axis movement

Glad it was helpful! In general you should expect bolts, wires, and other things to come loose or otherwise act up as you break your machine in. I recommend checking these regularly in your first couple of cuts. Setup, vibration, and movement are guaranteed to make a slightly loose bolt become very loose! Here are some other things mistakes I’ve made that maybe you can learn from:

  • One of my Y Axis motor couplers came loose and the Y Axis got misaligned. I had to tighten the coupler’s collar screw because the motor wasn’t properly spinning the ball screw shaft.
  • I pulled a motor wire loose from it’s connector when securing the wiring, causing Y Axis misalignment again - motor wasn’t turning at all.
  • I didn’t make the tabs thick enough on an early cut, the piece came loose and damaged my 1/4" downcut endmill when it cut into a hold down bolt.
  • I didn’t know you should flatten your spoil board. Mine is only about 1/16th over 36" and I mostly cut small parts so I haven’t flattened mine but if you are going to cut big things, make sure your board is flat! An easy way to check is to lower your bit to about 1/8" from the spoilboard and jog it around slowly, checking the gap. There are more sophisticated ways to check but this is a simple way.
  • The default tool speeds are REALLY conservative. I often run my cuts at 130% or manually change the feed speeds. If you do this, start slow and listen to your router RPMs.
  • I have a sort of “pre-flight checklist” that helps remember all the things to do when starting a cut so I make fewer mistakes.
