literally… i have about 2000 hours on my first machine. Built a second machine, much stiffer, tighter etc… rail size 600x900.
x-controller, all Inventables parts…
here’s the problem…
my work zero WILL NOT set to 0,0…
it homes perfectly to 0,0… every single time. but no matter what i have tried, it starts every cut at .5, 0.
so i was trying to skim the wasteboard, and it will not start cutting at 0,0. it jumps out to approximately .5" in the x position before it starts the cut, then travels the perfect distance, at least it crashes into the stops.
when the job finishes, it returns perfectly and repeatably to 0,0.
is there a safety buffer setting or something in GRBL??
I have positive stops on x and y rails that I use to orient the machine before powering up the controller. So that sets my 0,0 point for each new carve. I use corner stops on the wasteboard to orient material on this particular machine.
As needed, I jog to the corner on any other workpiece, set x,y,z-zero there.
But in this case, I want my wasteboard skim route to be anchored at 0,0 as that’s where my machine zero is. The final size is 100% perfect, in every direction. The only issue is the offset to the right.
