Hello again, i use fusion 360 to makes my model and for the post-process to transfer in grbl. I dont know, why when i ''run'' the program the spindle goes down instead of going up, to go from the xyz=0 to start the job. After it begin, everything is going the right way... I find that if i erase the line #10 and add Z0 after the G90 on line #11, the Z axe stay the same and the spindle goes over the right spot and start the job.. Can you help me? Thanks Marco
Use the OpenBuilds Fusion Post: docs:software:fusion360 [OpenBuilds Documentation] Make sure you home your machine before setting work zeros. The first move will be a clearance move to G53 Z-10. That's 10mm below your Z limit switch.
Not strange at all. G28 is a stored position, stored as an offset from home. (often used for tool changers) The default offset is 0,0,0, which is the same as home. GRBL, the software in the controller, sets 'home' to be where it turns on or resets, until you run a homing cycle. The behavior you describe is what happens when the machine is not properly homed. The standard home position is Z UP as far as it will go which is positive tool travel. X to positive tool travel, Y to positive tool travel, which is usually right,back,up for a gantry machine. Some more info Home, Fusion360 and G53 Z moves
But rather than the built in fusion Grbl post that uses confusing G28, rather use ours that uses the easier G53 concept as linked above
I went to '' docs:software:fusion360 [OpenBuilds Documentation] '' and try to do the procedur, every thing is ok until i get to the #3 step. I can't find this dialogue box: When i click the post traiment in F360 i get: What am i doing wrong? Thanks Marco
Same window just newer version of Fusion Under Machine et Post Processeur you already have OpenBuilds selected in the Dropdown
