General Mach Discussion / Milled hardware don't match software preview
« on: April 08, 2009, 12:56:06 PM »
Hello,
when i mill an smd pcb the edges wich are straight on the preview arn't straight at all... here is a picture:
The milled region is 18x24mm... so it's realy small...
I use a zigzag motion to cut out the PCB because there is backlash on my X-axis. Normally the G-code file isn't the problem since the preview is ok.
Here is the g-code file:

What could be the problem? I use the PICStep boards.
