I imported G Code from Fusion 360 into Easel. At first, the cut was going swimmingly (such a strange phrase, swimmingly. Who came up with that?). Then it was like the spindle decided to get ready for a deep dive. It went all the way to the top of the Z axis and then plunged down into the wood, burying the bit all the way down to the collet. It then proceeded to perform its cuts like “normal”, except that it was still down at that level and burning the wood as it dragged the collet around over it.
I’ve simulated the cut in both Fusion 360 and Easel. Neither had the plunge.
When it went to the top, it probably crashed. It “thought” it went higher, so when it came back down, it went too far.
Now, why you had the big retraction is the question.
Can you share your gcode and/or your Fusion file (.f3d)?
Sorry for the delay, I was reading up on the history behind the weird “swimmingly”.
So this happened when you started the detail job. What sender are you using? How did you handle the M6 Toolchange. Did you rezero your Z?
The gcode looks fine and shouldn’t have caused the big retract.
It happened in the middle of the detail job.
Is the “sender” the post processor? That would be the x-carve post processor. And I used Easel to run the job.
The only tool change was between the roughing and finishing stages. Those were exported as separate gcode, and imported into Easel as separate workpieces in the same project.
I re-zeroed with the probe.
this happen to me when I started. All because the z gap was not set properly.
my Z started to go up and up and more up, the Nema motor also didn’t stop either. it also traveled down through the waste board.
That little decimal need be in the right place 0.02
