Workbee CNC 1500 x 1500 Belt - Duet Z Axis Issue

grezmel

Hi,
I am in the process of commissioning a Workbee CNC 1500 x 1500 Belt, standard set up from Ooznest. The X & Y axis travel seems spot on, however, when I run the attached G Code, The Z Axis mount travels too far and the bottom of the mount hits the deck.

The Gcode was created in Fusion 360 and the simulation ran as expected. When I measure the travel on the Z Axis by sending 25, 50mm code to the machine, the measurements are fine.

Can anyone assist, 0_1557575473497_Waste Board.txt please?

Thanks

Where is you Z0 relative to the workpiece?

Where is you Z0 relative to the workpiece?

Z0 is set to bottom left - I have run a test with the Z at full height and zero'd at full height as it should only move down a max of 6mm for the board I'm trying to machine, however, the Z axis moves all of the way to the bottom hitting the board. All other Axis appears to be working fine.

@grezmel you have Z-5.6 and Z-7 in your G0/G1 commands. You might have to re-check how have you defined your workspace in Fusion 360 when generating the GCode.

fusion post proc probably does either g28 or g54 g92 z0 at the start which can cause issues if your machine isn't set up right.
