Topic: Fan placement and Appropriate Temps for extrusion
I got my filastruder on Friday, assembled it and did my purge. That all went well.
Now I am trying to get in to "production mode" and wanted to ask about how to produce good filament.
First off, as I was doing my purge on a 3mm nozzle at 180 degrees (per the instructions), my filament was coming in between 3.2 and 3.3 mm. According to the forums, it seems that I should just dial up the heat until the filament is the proper diameter. First set of questions...
>> For ABS, what temp do most of you extrude at? What about for PLA?
>> Is it the same temp for 3mm as 1,75 or will I have to have a 1.75 temp and a 3mm temp?
>> I am guessing that if I use the osprintingllc filament that I will have one temp and if I use a different polymer from a different manufacturer, I would need to find the correct temp.
>> Do I have to adjust the temp for every masterbatch I add (like having to adjust printer temp when I use a different color)? Or is the temp tied to the pellets alone?
Secondly, I think I have to tinker with my fan placement. I was getting quite a bit of ramen during my purge and also had problems keeping my temperature consistent. Even if I set my temp at 200, I never really ran above 175... and autotuning didn't really seem to help much. So next set of questions...
>> How do I know if I have good fan placement?
>> I am considering getting an enclosure, will that help me with the fan placement and consistency? Or is the enclosure more or less decorative?
>> Is it normal for the temperature to not reach the set temperature? Or is this due to my fan placement or another issue?
Finally, I have the filawinder but I haven't finished wiring it. I noticed during my purge that every time I bumped my filament a little bit that I got a deformity.
>> For those of you who have the filawinder, how do you get the filament to go through the PTFE tubing without deforming? Or is not a problem?
Thank you for entertaining my n00b questions.
