I was running a job and 4 hours in the machine got a lost connection error.
I restarted everything and tried to rerun the program, it give me a warning and said that it would plunge under the material into the wasteboard by 6mm.
In the process of trying to figure out what’s going on I realized that when I lower my Z axis all the way it no longer reaches my workpiece. In stops short. It seems I’m losing like 1"+ on my ability to plunge down.
I looked and searched around and no obvious visual issue (except the slides on the linear rails don’t go all the way to the bottom, they stop around 1/2" short, maybe this is normal, not sure)
Searching around I found this might be the potential problem?
What is more likely is that the origin was set with a longer tool, and a shorter one is now installed and that you are okay to go ahead and finish the cut.
This calculation was changed in more recent versions — once you are done, please update Carbide Motion:
which in addition to updating how this is handled, adds a facility for continuing an interrupted cut.
