What did you cut to measure the sizes? Can you cut some paper or engrave something to see if it is not some material-related issue?
It's independent of materials, we measured an older piece from a few weeks ago and it also had that error (just wasn't noticed due to a much larger scale).
Also note that the hole size and part size both have the same error - if the cause was just material burning away, holes should become bigger while parts become smaller :-/
That sounds like there is some backlash in the XY drive of the cutter. Maybe one of the pulleys came a little loose and is causing the loss of the 1/4mm.
Since we will be giving back the Laser tomorrow: Can we close this? ;)
Laser is gone, so let's close this.
Gregor and I noticed today that the Epilog Zing laser cutter we are currently using is not accurate enough for some technical parts.
Example measurements with the same Vernier caliper:
What definitely sticks out is that there is always a similar amount missing, not a factor (0.35 mm missing, or 0.175 mm per cut).
we already determined that
Any ideas what we might be missing?
