Netfabb extruding way too quickly

[somerwil 0]

Hi guys,

I got myself back into 3D printing again after nearly a year without touching it. :-). I obviously tried Cura but I was a big fan of Netfabb and I have a license for it so I decided to give it a go as well. That doesn't mean Cura is worthless, it's just another good option.

My new laptop on W8 has the latest version of Netfabb installed (4.9.5) and the 'Cura firmware' is uploaded on the machine.

I tried to print something directly from Netfabb which seems to be working correctly. My problem is the extruder motor makes too many revolutions resulting in huge amounts of material on the bed and grinding the PLA on the bolt in the end...

There must be something wrong in one of my settings. Perhaps a mismatch of firmware/gcode?! Don't know where to begin to be honest...

Try this bit of code in your pre gcode

M92 E835 ;Set Extruder Rate

Ah, that's a totally different from Netfabb's standard now which is M92 E14.

Should Netfabb be on "Ultimaker volumetric" or the normal "Ultimaker" setting (without the volumetric).

Hi Somerwil,

With the new firmware you need to have the Ultimaker on Volumetric as the firmware is designed to work with volumetric calculations. If you have it set right then you no longer need the M92 E835, which was an old work-around from before NF supported Volumentric.

Cheers,

Troy.

Does that mean that this does not apply?

Yep, that doesn't apply for Volumetric and probably no one uses the Non-Volumetric anymore.

Okay, thanks Owen.

I haven't played with Netfabb much at all yet, because I haven't had the time to figure it out yet. I like that it is more customizable in print settings than Cura, but it is not very intuitive, and the lack of tool tips make it a pain to get going quickly.

Do any of our Ultimaker gurus here have some print profile settings they could start me out with?

It seems to be overextruding for me as well. Very visible on the first couple layers of perimiter passes, where you can observe a bunch of overlap.

Hi Lars
