CNC or Vector Issue?


What could be wrong?
On X-axis ( left-right extreme) i see straight cut, instead of circle/arc.
On Y-axis ( top-right extreme), complete arc/circle, no issues at all.

The same vector file worked well sometimes back, so nothing seems to be wrong with the vector file.

How to troubleshoot this on the CNC mechanicals? or something else that i could not imagine.

The best check for the machine is to power up, install a probing pin, jog to the center of motion for all axes, then grab the tip of the probing pin and try to shift it in all possible directions — it should be steady, any aspect of movement should be investigated.

If the machine checks out mechanically, then the question is if the geometry is drawn accurately — if it is, then the toolpaths may be looked into

and feeds and speeds checked out:

What CNC are you using?

Please send a wide shot of it from the front and send it over.

@sandeepdhariwal, how are you fixturing your workpiece? Is there a possibility it may have shifted during the cut?

Hi Randy, No thats not possible, workpieces are fixed like anything, it wont move a mm.

That’s not something which we can assist with hardware-wise. This is a forum specific to Carbide3D machines and software.

The car analogy would be going to the Chevy Corvette Festival at Carlisle, Pa and asking for help with a Mercedes Benz truck.

I would suggest finding either a forum specific to that sort of machine, or a general CNC forum such as the CNC Zone or somewhere that deals in that class of machine.

If you are using Carbide Create Pro, post your file, but I suspect it’s going to come down to something like:

  • tool not loaded properly
  • worn/bent tool or collet
  • wrong feeds and speeds
  • running a finishing pass w/o a preceding roughing pass

Make a new post with the file if you’re using Carbide Create Pro and we’ll look into this with you on that basis.
