Prime Pillar Extrusion Multiplier

[LeoLautsprecher]

Hello!
I'm printing a lot with PLA and PETG. They don't stick together very well, so they are the perfect combination for parts that need support.
Prime pillars higher than about 5cm always suffer from delamination, in my case. To solve this problem, a extrusion multiplier for the prime pillar would work very well.

This problem could also be solved by adding a command in the gcode, when a certain feature is completed. Something like:

Code: Select all

; prime pillar start
G1 X188.001 Y123.083 F6000
G1 Z1.334 F1002
G1 E7.0000 F3600
...
;prime pillar end

That way you clould use post processing to get something like:

Code: Select all

; prime pillar start
M221 S140
G1 X188.001 Y123.083 F6000
G1 Z1.334 F1002
G1 E7.0000 F3600
...
;prime pillar end
S221 S100

Adding this would also allow much more features like swithing a special fan on, only when printing a bridge.
Generally speaking, the post processing leaves much to be desired.

Best regards,

For everyone having similar problems, here ist my post processing script, that kind of solves the problem:

Code: Select all

{REPLACE "; ooze shield" "; ooze shield\nM221 S140"}
{REPLACE "; prime pillar" "; prime pillar\nM221 S140"}
{REPLACE "; skirt" "; skirt\nM221 S100"}
{REPLACE "; raft" "; raft\nM221 S100"}
{REPLACE "; support" "; support\nM221 S100"}
{REPLACE "; outer perimeter" "; outer perimeter\nM221 S100"}
{REPLACE "; inner perimeter" "; inner perimeter\nM221 S100"}
{REPLACE "; internal single extrusion" "; internal single extrusion\nM221 S100"}
{REPLACE "; external single extrusion" "; external single extrusion\nM221 S100"}
{REPLACE "; solid layer" "; solid layer\nM221 S100"}
{REPLACE "; dense support" "; dense support\nM221 S100"}
{REPLACE "; infill" "; infill\nM221 S100"}
{REPLACE "; bridge" "; bridge\nM221 S100"}
{REPLACE "; gap fill" "; gap fill\nM221 S100"}

These are all the different feature types I could find. BUT: If there is some extrusion that does not begin with one of the commands listed above, it will just use the multiplier from above.
