Suggestion: Bottom Layer Travel Speed

Recommended Posts

A simple suggestion that I would really like to see is to have an input to change the travel speed on the bottom layer.

Often when I am printing the first layer, I print at 20mm/s for maximum adhesion to the build plate but I find that the super quick 150mm/s jumps to other places on the plate will drag the filament and pull it off. Having a slower travel speed, say 50mm/s, on the first layer would mitigate these issues.

Another alternative would be to have an adjustable, lower acceleration (but not deceleration) value for the first layer. Starts off slowly to ensure it doesn't pull the filament off then accelerates to the normal speed.

If this functionality already exists please let me know :)

I feel you Rhino, For now I've been turning combing off and turning on z-hop ( the .075mm seems to work just fine). You can keep your travel speed at 150 or whatever... This makes the printer retract nicely, even on the initial layer. Combined with a slow 20 to 30 mm/s first layer speed, this really cuts back on filament dragging and stringing.

It should be noted that I really only do this for thin complex prints that don't have a lot of layers.

I think you'll be able to do what you ask in the first release of the new version of Cura code named "pink unicorn". I believe you can assign ANY existing parameters to a region of the part (such as first layer only).

 

No, that's not true, you cannot assign any parameter to any region. But I can add a lot more parameters without making it insanely complex.

    • "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.
