Newbie- Milltronics VM16 Cent V

[muttley69]

Hi all
New to Milltronics but got a good deal on a machine so I bought it. I am having a problem with the x axis. It cuts small in comparison to Y, I tried adjusting the scale factor in the parameters but no change. I am running G-code programs so that may be why the parameters didn't change anything. The scale seems to be off about .0012 per inch. Any help would be appreciated.

Is the error consistent for all moves? A 2 inch move gives a .0024 error, a 10 inch move gives a .012 error, a 20 inch move gives a .024 error, etc?

If so, it could be several things: a bad encoder, a bad Ball Screw comp table, the wrong PPU parameter, bad motion control, etc.

If not, positioning problems are frequently backlash problems: bad or loose thrust bearings, bad or loose ball screw or mounts, loose or worn drive belt or sheaves, etc.

Good luck finding the problem.

Any updated info from ZZZZ questions?

On your G code programes, are they posted from a CAD/CAM?

If the rate of change stays the same, .0012 accross the travel I would suspect a bad thrust bearing / backlash problem.

We neeed more info

questions? just ask
