Just had a really wild experience. Started a carve for a lithopane using the sled I made just for them. Watched it start and went into the next room
to work on something else, came back in a few minutes and the carving was going on but it had shifted the entire carve toward the keyboard
side of the machine. Attached pic shows the shift of 1 7/8 inches. You can see the first passes going across. I had just upgraded from 1.186 to 1.187
and thought at first there was a bug. Cut a scrap piece of 3/4 plywood and reran the same MPC and it went fine( I shut it down after 10%).
Am going to replace the sled and try again, just glad it didn't shift far enough to hit a screw. I think I will use glue only to laminate on the new sled.
Anybody else ever seen anything like this happen??
Sled idsa piece of 1/2 MDF with a piece of 1/4 with the center removed laminated on top.
Material was 1/4 bronze acrylic, trying the method Jeff Birt used without backlite.
Bit was 1/32 used in the same project.
MPC is attached with pic of carve.
