Cura - UM3 - Prime Blob Amount

[MichiB 1]

Hi,

is there any way to increase the amount extruded for the prime blob?

I would like to extrude more in order to make the blob stick better to the print bed.

Thanks!

I don't think you can, you can instead disable the prime blob and write your own prime gcode.

go to the manage printers screen and click machine settings then set your gcode as the start gcode and you can apply your own version of priming for every print.

It can be edit using developer mode, using ssh to access the printer, moving inside share/griffin/griffin/machines/jedi.json (or was um3.json?) and changing the prime poop/blob amount to any amount your heart desires.

@bondtech has a step by step manual to edit the esteps, I say this because esteps and prime poop are on the same file and all is editable, so reading this manual is the fastest way to do it right.

Read from page 12-13 and read before doing it blindly, you need to change other parts of the file.

If you brick the machine you can do this

And all this stuff to just change the prime amount... Wow
