adding prime blob to .ufp file

[ScanHD 32]

Hello everybody. 

 

im having trouble printing a model that has always printed sucessfilly previously, but im using a new material and the for some reason its missing some of the lettering at the very beginning. My suspission is that its not primed properly.

 

is there a way to as a prime blob to the .ufp file to ensure it is primed?

 

recreating the program in cura is not an option as it took me a long time to get the settings right and i lost the cura file.

 

any help is apreciated.

A .ufp file is "just a zip". You can open it in a zip program (eg 7zip), extract the actual gcode file to edit it, and put the edited file back in the .ufp file.

G280 is responsible for the initial material feeding. The additional parameter S1 prevents the "blob".

It should be sufficient to substitute lines 31 - 32
