Carbide Create G-CODE


(Peter Lundh) #1

Hi all creators-

Line 12 (Bold and Italics) in my G-Code generated with Carbide Create for Nomad883 contains ’A0.000’, which makes Z-homing incredibly slow (see below). Is there a reason for this?

Many thanks in advance.

In g-code G1A0.000 just means move the A-axis to 0. It’s the F100.0 that is the feedrate (4in/min), but your meshcam isn’t much faster at F114.3. So after you do a G1A0.000, later when you do a homing cycle ($H) back to the upper right, it goes really slowly? Weird.

FWIW I don’t see the slow homing on my Nomad with Carbide Create. It does however, go really slowly back to the work piece after a tool change in MeshCAM however, but that’s because it uses the plunge rate for it and I’d prefer a rapid back to the retract height first.

Hi Mark-

Thanks much for introducing me to G-CODE basics - I clearly need to read up on this. Still, I need to figure out why ‘Rapid Positioning’ was so slow - I’ll do some simple experiments today.

Best.
