Custom Gcode with relative coordinates: extrusion?

Recommended Posts

Posted · Custom Gcode with relative coordinates: extrusion?

Hello,

I am planning to print some tests in mid-air with a custom gcode.

When i use relative coordinates (G91) in the gcode, will this also affect the extrusion length?

So, is it possible to just use constant values for E like this?

G1 X 5.00 Y 0.00 Z 2.00 E 0.0024

G1 X 5.00 Y 0.00 Z -2.00 E 0.0024

G1 X 0.00 Y 5.00 Z 2.00 E 0.0024

G1 X 0.00 Y 5.00 Z -2.00 E 0.0024...

Or would i have to do it this way?

G1 X 5.00 Y 0.00 Z 2.00 E 0.0024

G1 X 5.00 Y 0.00 Z -2.00 E 0.0048

G1 X 0.00 Y 5.00 Z 2.00 E 0.0072

G1 X 0.00 Y 5.00 Z -2.00 E 0.0096...

Thank you very much!

Lars

By default it's the same as the mode as the first three axes. But you can change it for the E-axis only by using M82 (absolute) and M83 (relative).

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
