Slic3r with multiple extruders and different e steps?

Hi there,

I am using a TriColor Mendel and I am having issues with different e-steps for the three extruders. When I am setting the feed rate for the primary extruder to its ideal value (M92 command) , the second and third extruders have a too low extrusion rate which leads to small holes in the structure.

Is there any way to set in Slic3r for extruders other than the primary one a different feed-rate? If not, is there any other way to overcome this issue?

thanks and best regards,
KORYBA

hi,
you can adjust the feedrate

Have you tried custom g-code to select each extruder individually and set its e-steps per mm? Don't know if it will work, but it looks like the only way to do it through Slic3r.

There may be something you can do with the tool-change custom g-code and placeholders, but I can't see anything obvious (or even not obvious). Can't seem to find a list of placeholders anywhere.

3dKarma, this looks like a good idea. Alternatively, you can adjust the feed rate in slic3r for each extruder as a ratio of the first extrude rate.
