Whats wrong with my machine?

[DJGWoodworking (Doug Gauthier)]

I swear im at my breaking point with this.

Mid job, it will just stop going side to side or front to back. Both have happened, and just jump in place. Which then screws up the toolpaths. Someone explain this please, this machine was alot of money and it seems like every time i try to do a job on it, a new problem arises

Possible causes:

• something mechanically blocking the machine
• mechanical problem:
  • pulley set screw: Checking Pulley Set Screws - Carbide 3D
  • (for the SO3/4) V wheels / eccentric nuts: Tightening Eccentric Nuts - Carbide 3D
  • (for the Pro) Lubrication of the linear rails: https://docs.carbide3d.com/assembly/linear-guide-maintenance/Linear_Rail_and_Guide_Maintenance_02-17-2021_v1.0.pdf
  • Belt tension (see the relevant step in your instruction manual, e.g., Step 5 Belting - Carbide 3D) Note that the X-axis motor is held in place on standoffs and if those bolts are loose this can cause belt tension issues. Also, belt tension for the Y-axis stepper motors needs to be even/equivalent on each side — a significant difference can cause skipping on one side eventually resulting in lost steps on both. Measuring belt tension, squaring and calibration
• problem with the toolpaths or feeds and speeds — these need to be set up as to be appropriate to the tooling and material — avoid slotting (cutting a slot as narrow as the endmill) where possible

If you continue to have difficulty, post your file and step-by-step notes on how you are securing your stock and setting zero relative to it and managing all tool changes and a photo showing an attempt at cutting still on the machine, either here, or to support@carbide3d.com
