I’ve run into an issue with my x-carve where designed objects are smaller than they should be by ~2/64ths in x and y directions. If I draw a 2" square in easel, and make sure it is set to outside cut and it’s short in both directions. I don’t hear anything strange when cutting, I don’t think I am missing steps. All tests were done in MDF w/ 1/8" 2 flute upcut but @ 40" feed rate.
- I’ve calibrated both the x and y directions to be accurate within 1/128th" over 30" by using UGCS (g0 x30). I’ve checked this twice. Maybe use G1 x30 f40?
- I’ve played with the stepper motor voltage pots. I’m pretty sure I have them dialed in correctly.
- I’ve adjusted the voltage output of the main power supply from 24.3 to 24.0. - I saw in one video incorrect voltage could cause missing steps.
- I’ve ensured the belts are tight, but not too tight.
- I’ve verified the v-wheels can barely be spun by one finger - I’m pretty strong, so the average person could move it with 2 fingers.
This inaccuracy is very consistent on both axis. I even wrote a gcode file to cut a square to see if Easel was the issue without any difference. I have a older x-Carve pre-2016 with the g-shield. I’m using a dewalt 611 for my spindle and I’ve stiffened the gantry. Z axis is rock solid.
Any help is much appreciated!
