So I'm new to cnc and I finally have my machine up and running after calibrating it.
So here is what happened. I made a jig that I could place a 3.5"x3.5"x12" block of wood in. I cut this jig with my cnc. I had it drill two hols in it so I could put some short screws from the bottom up into the block. As it was drilling one of the holes it said exceeded soft limit. This is in EMC2. So that's the first time that has happened. I thought it was just a glitch. So I restarted EMC2 and same problem. It drilled the hole regardless before the error so I figured I would solve that later. Now that my jig is made I placed in my piece and ran my program. Everything worked beutifully, but I relized I had to make a minor adjustment to the size of a cut. So after the fix I ran the same program again. Pretty much cutting all air since it was only going to fix one part. As it neared towards the end and it was dropping down for a finishing pass it kept going and probably would have went into the table had the screw.... that's right.... the screw hadn't stopped it. This is the same spot on the table where it had the exceeded soft limit issue. So I'm thinking there is a connection between the two. Weird thing is that program ran fine before and I didn't change anything that would have caused it. I checked it after it wrecked my bit and almost my router. Anyways, what could be causing this. I use cambam and EMC2.
