extrusion works manually, but not during print

Recommended Posts

The extrude button in PrintRun should extrude a few mm of filament each time. It it only moves a tiny bit, then you might be using old firmware. Did you upgrade to the firmware supplied with Cura?

The "e_feedrate" setting is 300mm/s per default, it's also shown near the extrude button on the lower left. The default is fine. And this value is never used during printing.

Did you generate the GCode that you are trying to print with Cura?

Alternatively, try entering "M92 E865.888" in the immediate window at the lower right corner, before printing/extruding. To see if this makes a difference.

Daid,

Thanks for responding.

After I got my machine assembled, I tried using ReplicatorG at first and had updated the firmware through there. Is the firmware for that vs. Cura different?

Yes, the gcode was generated using Cura.

Maybe I will try the Cura firmware tonight if you think that will help.

Thanks,

David

Yes. The Cura firmware is much newer then the RepG26 firmware. If you use RepG34, that should have about the same firmware (but I do not know the defaults of the RepG34 firmware)

Setting the "steps per E" to 865.888 in the preferences, and then slicing again would most likely also work. But it's better not to use a firmware from RepG26 or lower.

Daid,

Thanks for your help! I loaded the firmware supplied with Cura, increased the "steps per E" value, and tightened up the pinch knob on the extruder and got things working with PrintRun. I printed the twisted bottle from Thingiverse:

and then I made something of my own design:

I need to play with the settings some more, so I may have to pick your brain again in the future. :D

Thanks,

David

    • "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.
