Using Vcarve to create gcode to cut a pocket 1 inch deep by .25 wide by 1 inch long in stock that is 1.5 inches deep. Using a .25 inch millend. keeps plugging pass 1 inch and jamming the router into the stock. I did multiple pocket cuts earlier today that were .75 deep and they were perfect. What am I doing wrong??? Using Carbide motion to run gcode.
Usually this sort of difficulty is mechanical.
Always check the machine per the checklist: https://docs.carbide3d.com/general-faq/machine-operating-checklist/

- V wheels / eccentric nuts: http://docs.carbide3d.com/support/tensioning-eccentrics
- Belt tension — the Z-axis should be guitar string tight (but careful not to bend the motor shaft): http://docs.carbide3d.com/assembly/shapeoko/xxl/step-5-belting/ on deep cuts it may help to remove one spring from the Z-axis temporarily, esp. if one hasn’t added a spoilboard on top of the wasteboard — it also helps to install the router as low as possible (installing the Makita adapter upside down will help). Some folks have found it helps to remove the M4 Z-axis tension bolt, apply a thin bead of threadlock along the length of the threads, then reinstalling it after it has dried.
If those things don’t pan out, let us know at firstname.lastname@example.org and we’ll do our best to help.
Perhaps you could attach your C2D and NC files for us to look at to see what you are doing wrong…
Retract height seems to be a bit over an inch — do you have 1" of clear vertical travel from where you set the zero? (assuming it’s on the surface — the stock is 1" thick?)
NC Code looks correct. Maybe you set your Z at the bottom or the top of your part?
