Slic3r v0.9.8

I read somewhere that if you were printing with PLA and your head was dragging the PLA around the corners then you probably need to bump up your PLA temperature slightly.

The problem is, my PLA temperature is already at 195, and when I try to change it to 200 - Slic3r changes it back to 195...

Slic3r doesn't know what material I am printing with, right? So why is it putting a cap on how hot I can print with? What if I wanted to print with ABS?

NOTE: Instead of bumping up the head temperature (since I couldn't) I tried bumping up the filament multiplier to 1.1 and it seems like it might be working better? I'll have to experiment more, but I'd still like to know how to get the head hotter..

Filament multiplier and temperature are two completely different beasts.

Firstly, slic3r DOES know about the hot end temperature. That is set in the Filament Settings. What host are you running? You should be able to bump the temperature AFTER the program starts running. If you try to bump it before, the temp embedded in the gcode by slic3r will indeed set it back.

The multiplier tells slic3r to output more filament than calculated - in your case, 10% more. I suspect you will run into other problems with that.

You also do not mention if the head is dragging PLA around on the FIRST layer or on the higher layers. If the first layer, than odds are your Z=0 is off (too high) and you are not getting good stick.

Thanks for your reply, but perhaps I wasn't very clear. When I go into Slic3r to configure the filament, I type in that I want a first layer temperature of 200, then I click the save icon and when it refreshes, my temperature is back to 195.

I am running Repetier-Host V0.84 (mostly because I don't know what else to use).

I also understand what the multiplier does, I was simply stating that printing with the multiplier bumped up seemed to produce a nice clean print, although with MUCH more material than expected (Ie: More than 1mm thick walls on the 0.5mm thin wall print).

Also, it drags around alot on the first layer and it seems to drag less from there. I've double checked my Z-height, I am 1 sheet of paper away. I can just barely see light between the head and the build plate when looking real close.

Are you running Slic3r from within Repetier Host? If so, you need to tell repetier to refresh and configuration changes you made in Slic3r, otherwise it will use the original settings it loaded into memory when you launched RH. On teh Slicer tab, there is a button at the upper left called Slic3r - that will reload all of Slic3r's configuration files and changes.

If that isn't the issue, then I don't know what else to suggest. I just tried it and it is working fine for me. The "proof" is in the gcode, take a look at that. You can also edit the gcode directly in RH so you could change the temp there too.
