Max V4 Scaling problem

Post by brianmichalk »

My horizontal scale is off by 1.5%. I just finished updating to the latest 3.2.2 firmware and recalibrated the machine, but the scale is still off.
I edited the arm length in config.g, but that doesn't help. The config-override.g still has the wrong lengths in there, but the comments say to not edit that file.

What's the accepted procedure for calibrating these days? Lots of older documentation out there.
For an RMax V4.
I have an Artemis, and old V3 that work just fine, so I know it's not my slicer. I am directly measuring the head position with calipers after moving from the dashboard, and these measurements are agreeing with my parts dimensions.

That file looks good. Can you also post your bed.g file? That will tell me what RRF is doing for the calibration.

tnx.
