But the linear error seems to be different for every quadrant.
Also there is an error on the X axis when just moving on the Y axis.
For example:
If you draw a line on the X axis with y =0
and you draw a line on the x axis with y=500
you will see that the lines will drift apart (y).
So you have to compensate y for x movements too.
I know the adjustments are better done in the maslow but i didnt want to mess around in the firmware.
I have a few posts on this, but I think this one gets to the heart of the accuracy issue and why it’s not linear: X & Y Accuracy Analysis: Belt Stretch
I’ve had to take a break from this research, but next up I want to work with @bar to create a setting in the software that can compensate for belt stretch and keep testing. Hopefully I can get back to it soon!
Question about the x and y scaling option:
I ran my first cut yesterday. Cut out a rectangle of 2000mmx38.6mm
Y isn’t off, but the x measured 1982mm after cutting. What value do I enter into scale x window to compensate?
Do I enter the scaled value 1982/2000x100=99,1 (0.991) or 2000/1982x100=100,908 (1.009)
My 3D printer (klipper/fluidd) asks for the first value to account for filament shrinkage and automatically compensates so the dimensions are accurate again.
X axis Scale correction 1.009 worked out fine!
Designed a quick test stool in Fusion and let Maslow work its magic!
I set up the slots and pockets with a 0.1mm tolerance. For the seat pockets that turned out a bit tight. Had to do some manual “post processing” to make ik fit. But for a first project I am more than happy with the results!
Excellent work! I’m loving following along with your exploring of how we can improve the system accuracy, but it’s also good to see that you are able to use the machine as is too
