Cura gcode start

Recommended Posts

I have a 3d printer at home (M3D) and we just got an Airwolf HD2x where I work.

I use Cura for slicing and gcode creation in both cases, 15.04 for my printer and 15.04.3 for our work printer. My question is, why do my parts perform a gradual approach when a print starts? What I mean is, the print head will start along the path of the first bead but it will take anywhere from a few mm of travel to a few inches of travel before the print head is close enough to the surface to start laying down filament. So basically, my prints have a line of missing material.

Is there a setting in Cura that makes it behave this way?

Thank you so much

Sorry, but can you share some more informations?

- Which printer profile do you use within Cura?

- How does your start gcode looks like?

A short google search found this example profile for the Micro 3D

...and the Airwolf FAQ mentions a "recommended profile" for Cura "provided on the USB drive received with your printer"...

Have you tried this already?

Anyway... it's just my personal thought, but i assume the Cura developers can only make a guess about your printer(s). Perhaps the linked sites are a better place to ask...?

Thanks for the response. For my M3D I'm using the example profile that you linked. For the Airwolf, I set Cura up per their instructions in the user manual. I loaded the ABS profile from the Airwolf USB drive and the only things I changed were certain parameters (fill, shells, etc.). I didn't change anything about the Start/End G-code.

My workaround so far has been to print everything with a raft or brim so the printer is laying down filament by the time it gets to the actual part. I'll paste the G-code start below:

M190 S115.000000

M109 S240.000000

    • "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.
