I have LR-V4 moving and square to within 1mm (!). My table is roughly 3x5’; I’m trying to set X and Y max limits to 930mm and 1220mm.
I’m changing [ /axes/X/max_travel_mm ], saving then restarting the jackpot 3 controller, but I’m still able to move past these limits. Is the the right parameter?
That only works if soft limits are also enabled. They can sometimes cause grief though.
Makes sense! I’m coming in from 3d printing (Klipper) where build space is pre-defined. I can see where limits here, depending on co-ordinate space could be an issue.
It’s more involved than that. One really great thing about the LR4 design is that all of the cutting work is done by the cutter and the spindle. That’s obvious in retrospect, but it’s what really does the work.
The LR4 is considerably more capable than the ability of the spindles and cutters we use, but not so powerful that it can cause any serious damage to itself if you run beyond the machine workspace. It sounds horrible to have the machine missing steps at edge of travel, and it might ruin your job- but that’s more about your gcode than anything. The horrible sound of missing steps won’t break your machine. If you seriously mess up to the point that you have to hit the EPO, you might find the machine has walked off the Y rail or has been hard against a physical limit.
But, you can then calmly set everything back and start over without a horribly broken machine.
