Extra extrude after tool / extruder change

[CaptainPlanetHD]

Hi!

I installed and tested my copy of Simplify3d yesterday, till now everything works good. But I have one question right now.
I made an example part - just two rings(20mm diameter 0,8mm wall thickness 3mm hight) one placed on top of the other. I want to print the first one with extruder 1 and the second one with extruder 2.
It does work so far - the only problem is that it would need some extra exrude for the second extruder right after the first has finished. The first two layers lack of extruded material form extruder 2. Same problem as if you would start your print without perimeters...
So is it possible, when the first ring has finished extruder 1 retracts and extruder 2 travels to some outer position, extrudes about some mm and then starts to print?

Thanks.

Bye
Boris

Yep, this is doable through the Tool-Change G-Code tab of the Scripts tab in the FFF settings. You can copy-paste this directly in, [old_tool] and [new_tool] are placeholder variables Simplify3D uses

If you have a MakerBot/SailFish printer

M135 T[old_tool]
G1 E-15 F1800
M135 T[new_tool]
G1 X80 Y80 F4500
G1 E15 F225

If you have a RepRap/Marlin printer
T[old_tool]
G1 E-15 F1800
T[new_tool]
G1 X0 Y0 F4500
G1 E15 F225



They're different because the tool-change is different for the two printers, and the coordinate system is different for MakerBot style beds vs RepRap style usually.

Good morning,

Ill give this a try (I have a RapRap/Marlin). Thank you very much for your help!
