no autolevel function on 5mm long lines in y direction

[neptunier]

hello,
i am engraving stainless steel handles 10mm wide 140mm long. these are not very straight and therefor i use the autoleveller software.
however i ran into a problem with 5mm long lines along the y axis (x axis is the 140mm long side of the handle). the handles are not level in the y direction. i made my rpf file with 2 rows of probe points. the probe points at that location differ nearly 1/10 of a millimeter.

however the autoleveller software just uses the entrance point z value , so at the end of the line the cut is 1/10 deeper then it should.

do i miss something or is there a way i could solve that issue. working out that issue is key to the success of that project.

attached are the ogf, rpf and autolevelled file.
thanks for your help,
michael

Hey Michael,

Thanks for all the information and files attached. It makes it much easier to diagnose.

I am using AE 0.9.5u2 which I presume you are too.

First I loaded the RPF file into AE which looked fine and as you described.

I then loaded the OGF into AE and expected to see a design in the drawing area, but was instead presented with this:

Looks blank. Also, it detected the x-width is 0, so this would explain why nothing is drawn and also why levelling isnt performed properly. I then opened the OGF in a separate editor and again there was almost nothing there.

I then opened the file in a text editor and saw only a few lines of GCode:

Code: Select all

Did you attach the wrong OGF or something?

I just had a thought on this. The uploaded OGF is probably just a quick test. and the lines within the file are well above Z0. AE wont level any line which is not negative. Could this be the reason for the problems?

sorry for the late answer, i was on holidays.
i am using the newest version. the file is right, i just tested it again, in my autoleveller it works. it is just one 5mm long line with a ramp in and out. but the z height is the same on the 5mm long path although the z heights in the probe file are different on start and end of that toolpath.

i attach them again.
thanks,
michael

hi fredeopopo,
the problem i had was on an actual workpiece. then i tried to find out the problem and posted the ogf. maybe i did a mistake there, but the problem remains with the short line, with z below zero..
