Custom Gcode for Ultimaker 2+

[KhanS 0]

Hi,

I'm new to 3d printing with Ultimaker. I'm looking to add a custom gcode for my prints. I'm trying to make the printer stop for 10 seconds after every layer so that I can take a picture. Is it possible to do it via Ultimaker Cura? 

 

I see that this might be possible in PrusaSlicer

If you are referring to the UltiMaker 2+ Connect

The answer would be no. The firmware does not support these pause commands from any slicer.

Hi Dustin,
Thanks for the info! Is it possible to pause the print on the S5?

Which firmware are the Ultimaker printers running? I couldn't find this information. Is it Klipper?

AFAIK, hidden inside each UM printer is a fork of a rather old version of Marlin. However the modern ones (Ultimaker 3 and newer, including the Ultimaker 2+ Connect) have a proprietary linux-based firmware shell around that Marlin-based controller.

No it is not Klipper the S series run a customized (older) version of Marlin which is referred to as Griffin 

This is not based on Klipper, its custom as there is a pre-processing module in the printer itself that intercepts the gcode and processes it prior to being handed off to the motion controller 

 

Yes you can pause the print (S series only, this does not apply to 2+Connect) with the post processing plugin in UltiMaker Cura, ensure "Method" is set to Griffin.

 

The 2+Connect uses a version of firmware similar to the S series but is very slimmed down due to the considerably reduced specifications of the hardware in the pre-processor

Speicifically, the UM 2+C uses this version of Marlin:

Support for the G4 "dwell" command (to pause for a number of seconds) seems to be absent from this version.
