Cut 5 of the “Lion of Judah” SLT head and on the 6th one, with nothing changed in the file from the previous 5, the XXL went bonkers. Standing watching it and for no apparent reason ( though there always is a reason) the cutter just started taking off in a bad direction. I had already cut the second to last and last tool path and then went to the first and second tool paths. It cut everything great as before but wen it got to almost the last line of the second tool path, the machine just jumped off track and started cutting straight into the lion head. I stopped the machine.
Checked the belts, the tool for tightness, the router for any strange “play” in the X,Y or Z but everything seemed fine.
Had to STOP the machine and reset the Z height since I was going to try and go to the middle toolpath, FINISH Toolpath, and run again.
Since I had to reload the program due to the STOP, I did so and when I looked at the preview in CM, it was weird. The frontal view showed “line holes into the full depth of the board” that should not be there. Went back and checked the file and the preview in CCP, and it did not show any such holes into the board. Just in case, resaved the file and reset the XXL and reloaded the file into CM. Holes still showing up.
SOOO… I figured, I’d just see what would happen.
True to the CM preview, the very first thing the machine started doing was drilling into the board. Obviously , I stopped the machine.
Here is a pic of the simu from CCP and one from CM.
Not sure what is going on nor what happened nor how to fix??
Sent the CCP file to customer support since it was to large to upload, even after zipped.
Appreciate any input.
Thanks
UPDATE:
Moved the CCP file to another computer and it shows a “complete cut through” at the bottom of the inside frame. That explaines why the CM did what it did when I reloaded the file. (Not what caused it to go off track initally…which is still a question.)
Now the real bottom line is: Same file run right in a row for 5 times without any “cut through” happening (because it was not in the design), BUT when it went to the 6th time running the same file, somehow a full cut through the bottom of the board showed up??
The changed happens during the Finish cut after the Rough cut. That Finish file somehow changed without anything changing in the design. ???
Just to show the previous cuts, here are 3 or the 5 that turned out great without issue. Why the change? and Why did the FINISH cut end up cutting through the board when the ROUGH cuts was finished with about 0.25" remained in the background??
