folger tech prusa and filament temperatures hi guys, i've had my folger tech prusa for almost a year now and i've noticed that, to get a proper print quality, i had to keep my nozzle temperature relatively low compared to the general consensus on print temperatures. To get a decent looking PLA print, i have to print as low as 173C. Even at 180C i get unpleasant saggy vertical walls. For ABS, i have printed down to 200C. The same ABS on my makerbot 2x prints comfortably at 230 with similar surface quality. The PLA in question is makerbot orange PLA, while the ABS i use both makerbot and some of the stuff folger tech sells. The results is the same for both the makerbot and cheaper folger tech stuff. TLDR are sub 175C (for PLA) and 200C (for ABS) print temperatures a normal thing, or is there something wrong with my folger tech? I've googled for information on this and can't find any except for a few posts mentioning they print pla at 177C. Nothing on the ABS at 200C. https://reprap.org/forum/read.php?406,672117,672117#msg-672117 Sat, 12 Sep 2026 21:58:00 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?406,672117,673841#msg-673841 Re: folger tech prusa and filament temperatures https://reprap.org/forum/read.php?406,672117,673841#msg-673841

so as i'm recently cleaning my hotend, i see that hidden ptfe tube inside, which i hadn't noticed before. Why is that there? Can the printer function without it? Can i replace it with a metal tube of the same OD and ID? Is there a disadvantage to upgrading to an all metal hotend with this printer?

Oh, and my thermistor wire snapped and the little resistor thingy unexpectedly flung off somewhere on the ground, lost forever, so i have to replace the thermistor for sure.

I think with the stock hotend if you took out the liner the filament would melt in the cool block area. Now you have an excuse to upgrade the hotend.]]> msaeger Prusa i3 and variants Sun, 12 Jun 2016 21:57:07 -0400 https://reprap.org/forum/read.php?406,672117,673699#msg-673699 Re: folger tech prusa and filament temperatures https://reprap.org/forum/read.php?406,672117,673699#msg-673699

Thank you Mach. I'll check it out this weekend. (i have to review how to get the marlin thing to make changes on my printer. I haven't done it since i originally built it).

I will also read up on the wiki in your signature. Thanks :)
Are you just a Folger Tech aficionado or do you work for the company?


If i had to replace the thermistor, would i just go with a stock replacement from Folger tech or do you recommend a different one?

on a slightly related note, how high of a temp can the extruder go? I got some taulman nylon samples i'd like test out.

I am just a owner of the printer that tries to help out others :) As for the thermistor, as long as it is a 100k thermistor, it should work fine. You cannot really print things that print at above 250C due to the PTFE tube in the hotend. Temps over that will cause it to start releasing toxic fumes, and then start deteriorating. For printing at higher temp, you will need to upgrade to a full metal hotend.]]> Mach Prusa i3 and variants Thu, 09 Jun 2016 17:38:13 -0400 https://reprap.org/forum/read.php?406,672117,672563#msg-672563 Re: folger tech prusa and filament temperatures https://reprap.org/forum/read.php?406,672117,672563#msg-672563

TLDR are sub 175C (for PLA) and 200C (for ABS) print temperatures a normal thing, or is there something wrong with my folger tech?

I've googled for information on this and can't find any except for a few posts mentioning they print pla at 177C. Nothing on the ABS at 200C.

Your hotend thermistor may be faulty. On my printer, the thermistor on my bed is faulty so it reads 20 degrees C lower than what it actually is. Also, make sure you are using "#define TEMP_SENSOR_0 1" and "TEMP_SENSOR_BED 1" as your thermistor defines.]]> Mach Prusa i3 and variants Tue, 07 Jun 2016 17:51:04 -0400 https://reprap.org/forum/read.php?406,672117,672117#msg-672117 folger tech prusa and filament temperatures https://reprap.org/forum/read.php?406,672117,672117#msg-672117
