First one I tried to do three in a row it just printed them on top of each other, the second one worked perfectly, the third one cut all the way through the material and the tabs, the fourth didn’t cut hardly anything, and the fifth one was doing great until it tried to do the interiors and it just randomly shifted down.
It just seems odd that there seems to be no sense of consistency, sometimes it cuts to shallow and sometimes it cuts too deep. I measured the wood with my digital calipers to insure the proper depth and I am rehoming the x carve the exact same way every time.
It only seems to mess up when the job is moving from one depth of cut to the other, for example it does the entire outside shape fine but then doesn’t start the second group of cuts at the proper location.
Well rapids is the fastest the machine can move, on the xcarve 8000mm/m. Usually when not cutting the code uses rapids. If you look at the pictures, the cutting is not distorted, but offset between cuts, so that means that the rapids are loosing steps.
My last post in the consolidation thread I linked has the main things I did in your situation. I had to cut 25 picture frames. Doing those mods didn’t take very long but was very much worth it. In fact it will save you time and headache.
You can change the rapid speeds, but it will not really solve your problems. These are your rapids:
$110=8000.000 (x max rate, mm/min)
$111=8000.000 (y max rate, mm/min)
$112=500.000 (z max rate, mm/min)
I have a similar problem with the carriage moving to a new location. But It overshoots instead of losing distance. First try: fine, second try, partway in the spindle moved up and over 1 /4 inch too far on the y-axis, third try: it moved up and over 1.5 inches too far on the x-axis, fourth try: all OK. Do I try the same solution or not? Steps are not lost but somehow the cut is shifted outward in one direction. When cancelling the run the spindle moves back to a home position which now reflects that shift.
