I am having quite a strange issue than I have yet to encountered in the 3 years I’ve owned my x-carve.
Just some background, I recently upgraded to the x-controller and stronger x-axis, I reinforced the y-axis myself, and replaced the x axis with a stronger dual rod axis. I had everything working great after the upgrades, with pretty good accuracy (way better than before).
Then I did a firmware upgrade. Next time I tried is when the problems started.
A few weeks later now, I’m trying to cut an aluminum plate. Using a double flute 1/8th inch bit made for aluminum specifically. The issue is the holes become off after the 5 hole is drill. The whole pattern becomes off afterwards. The weirdest part is the bit does return to the correct starting location when it’s done or canceled.
First thought is the belt is slipping. But the belt has good tension. Checked the pulleys to make sure the grub screws are not slipping, they are good also. This would make sense also if the bit returned to the wrong location afterwards (which I’ve experienced a fair bit in the past couple of years), but it returns to the correct location, so it doesn’t seem physical to me.
So I decided to redo the firmware on the machine. I re-calibrated all axises with calibers. Still, same problem.
Thinking this could be because the file is very old, that maybe, it wasn’t converted automatically to the correct format in all of the iterations of firmware of the machine and easel. So I created a new file, and redid the sketch again. Still, same problem.
I’m completely out of ideas now. Seems to me like a software glitch, but I have no way of confirming this.
Any ideas of how to fix this or what the problem might be?
As far as I can tell, yes. It starts from the bottom left corner, goes up to the next hole on the far left side, then the next hole above that, then back to the right and up again, then to the right, and now it’s time to turn around again, and the next hole is where the problem starts.
If you were to run the code again, does it do the exact same thing?
It seems mechanical. Is everything square when you start?Firmware wouldn’t make a difference if everything is calibrated. Can you share the project or gcode?
I also split this into 4 separate files (1 for each horizontal line of rows) and when cut like this, theirs no alignment issues. Then I tried to cut the plate out and that also messed up on the final turn.
I try not to assume anything. That’s why I asked if he starts the code again whether the holes were in the same place or not.
The OP also stated that the results vary each time…not code.
He also shared his Easel project. The toolpaths look fine.
He also stated that other cuts result in an error in the same place.
To me, this adds up to mechanical or electrical, not toolpath or design. Without more information, it’s tough to say for sure.
