Was there a change in the latest version of CM 517 where the “Z” no longer lifts up when you press the pause? I had a bit come loose yesterday. I heard it and quickly hit the pause expecting the Z to move up…however, it didn’t It just sat there, still engaged in the wood. I stopped the spindle and couldn’t get the Z to move with Jog or anything else. I ended up resetting the machine and reinitializing and it finally came up.
A related topic: I sometimes repeat a cut exactly as just run, to improve finish quality (especially on inlay VCarving). On completion of the first cut, the gantry moves up and to the back (Z moves up, Y moves back, X doesn’t change). So far so good. If I then hit ‘start’ again, the sequence is that Z drops to ‘safe height’, and then X and Y position to the 0,0 reference in the job. I know ‘safe height’ means that there should be nothing in the way when the gantry moves, but sometimes there is a clamp or similar ‘in the way’. If the gantry moved XY first, then finally drops Z it would avoid this entirely.
Using CM513 and most often gcode files from Vectric VCarve. I will check if the post-processor in Vectric is what sets this sequence, but I don’t recall it being so… It seems to be a CM513 thing
@NewToThis the necessity to tinker with post-processor scripts is down to Vectrics not being specific to any given hardware. CC doesn’t have this issue as it knows exactly which hardware it will be used with - hence no post-processor ‘editing’ either necessary or available
I too, have had the z-axis drop before going to the XY coordinates and it smashed into one of my clamps that I thought was completely out of the way.
I think your suggestion of XY positioning before Z is a wonderful idea.
It has to retract - just because one major reason for pausing is when you’re hearing something that’s not quite right and you want to check it out before completely committing a restart. Once you move X or Y, you’re starting again (unless resume returns to the same XY)…but raising it in place makes sense. For my problem, it definitely would have helped.
