CNC Troubleshooting | Router | Nudge / Nudging

Problem

Your print is not cutting through to the desired depth; this can be caused by a file issue, tool tip calibration or a worn table surface.

• Table is surfaced once per semester and should be assumed flat
• Tool tip calibration parameters may be incorrect
• File issues can cause unrepeatable damage to the CNC machines and if the issue is suspected due to a file you should stop you cut immediately and fix the problem in Fusion360.

If you experience any of these issues please send an email to soatechdesk@utexas.edu to ensure that a staff member is aware of machine or table damage.

Solution

The goal is to cut 100% through your material and not to go deeper than 1/32 of an inch into the spoil board.

1. Stop your job
   1. record the line # if you're expecting to resume
2. Type MN (Move, Nudge) in the command box
3. Nudge the Z-axis by -0.015 or 1/64 of an inch at a time
   1. each time a nudge command is given it will be relative from the current point. i.e. if you nudge by -0.015 then again by -0.010 you will be -0.025 from your original start point.
   2. 
4. Rerun your file with your newly calibrated Z offset position.
