Hi all,
meanwhile I have a lot of experience with all 3 functions of my Artisan (3D Printer, Laser, CNC).
Especially while doing Laser & CNC I am extremely careful all time.
But last week I had a crash. I was lasering a simple right angle tool for my CNC project. For this I was using a leftover piece of MDM. Because it was a leftover piece my fixing clamps have been inside the logical rectangle of the right angle shape. Knowing that Luban is going down to Z0 first and then moving XY to the start position I moved the laser above the starting point first by hand. Everything was excellent up to the end of the job. But then the machine made this unnecessary XY movement to 0/0 and then up. And then I had my collision with the clamp.
I do not understand why Luban is not generating machine code which is not as dangerous. Means during start do the XY movement first and then Z movement (down). And after the Job do the Z movement first (up) and then any XY movements.
I am modifying the GCODE very often because of this. But this time I was not prepared (or sleeping or lazy or distracted or …) and it happened.
Is my thinking /behavior wrong?
