Set up my machine to carve lettering font 3mm deep. I am a beginner. All goes well untill half way through; then the bit starts cutting into the work as it moves around the cut pah leaving straight linking lines in the carve. Eventually the job ends and the mill goes back to zero, leaving a 1mm deep trace through the work.
I assume that the safety height has changed half way through the program.
I am using Easel and a ‘Pro’ day. Day and stock wasted. Ho Hum.
Help. This is all greek (or GRBL) to me
