wrong extruder temperatur in g-code
July 29, 2015 02:07AM
I use the newes slic3r 1.2.9

The temperatur for my extruder is wrong in G-code. When I set 240° slice3r produces in G-Code M104 S215.
I always have to rewrite my G-code file manually.

Hope for some helpful hints.

Check your Custom G-code in Printer settings.

Well, in my start setup I use this code, but that may not be default:
M104 S[first_layer_temperature] ; set extruder temp

In your case I have no further clue...

M520 and M920 are custom codes not listed at:
[reprap.org]
Are those specific to your customized firmware?

Also check to be certain that both first layer as well as main temps are correct, and uncheck ooze prevention - it will do crazy things with extruder temp.

The point with start gcode, is that if you set temp (M104, M109) there, Slic3r will use that and not apply it's settings.

Does Ooze Prevention do it on purpose?

Yup, it's goal is described as adjusting temp to minimize ooze . . . It drove me nuts, and I don't use it. It *may* be more intended for dual extruders, but played hell on my single . . .

Yes, it is intended for dual extruders.

Where is the ooze prevention setting, so I can avoid it?
