Hi All... So I have built my new CNC machine - YAY I drew a picture with a sharpy - YAY I tried milling out a basic square drinks coaster drawn in fusion 360. I generated the G-Code however some issues then occurs. I loaded the Gcode into my Duet controller. I set the work zero - and the coordinates change on the webpage. When I run the g-code from Fusion360 a simple 2D facing operation the machine move rapidly moves to 0,0 of the machine, and then plunges the Z xis down. When I inspected the G-Code I executed line by line to try and see what was happening - Most commands are not supported as they are tool selection. - Then the command appears G54 - When I execute this the coordinates shown in the top corner revert back to the machine coordinates, meaning the next the command to run setting the X and Y are referenced from the machine 0,0 rather the work 0,0. Can anyone help? Something related maybe be when I hit the pause button the Z axies plunges into the workpiece then goes up, the x and y move a bit back and forth then all stays still. The movement buttons do not step the usual distance, much bigger distances. I have disabled G28 Safe retracts if that makes a difference? Home this all makes sense, G Code attached for the face operation. Happy to share access to the model in Fusion of that would make it easier to help with? Regards Colin.
