Re: What kind of updates have you made to your Folgertech Prusa I3? - 10 years ago

A few minor things. - Cheap Enclosure - Replaced extruder with Dual MK8 extruders. - Added 12v strip lights to the frame for better bed lighting. - For awhile I was using this spool holder I made with this filament guide. - Modified the bearing holders to this version. I will soon be replacing the entire y carriage with an aluminum version I have on order. - Replaced all of the PLA parts in the

Re: Folger Prusa i3 Kit from ebay - 10 years ago

Newtoprinting, As someone else mentioned your print temps are high for PLA. Personally I never go any higher than 210 for PLA and that is rare. Usually 180 or 190 for me. As far the barrel liner goes I had something similar happen to mine awhile ago and it never worked properly for me again until I replaced the barrel. (Yours might be fine but in my case it would not). I would recommend lowering

It would print fine for 10 minutes and then building up between heat block and fan/ filament drive. It might help if you take a picture of you setup or if the problem is visible the problem itself.

DMAN120 That is an awesome enclosure. Very clean looking. Great job! I am curious. Are you using the original PLA parts that came from Folger? If so how long have you been using them in an enclosure? I used a box over my machine for awhile when I was doing a bunch of ABS prints on it and the PLA parts that were under any tension expanded and became unusable. (It was about 50c in the "enclosure"

Amazon link for Extruders. The extruders are attached to each other. I was worried about the left extruder drooping down too much but the leveled out pretty well. For now it works until I have time to make a new mount.

It has been some time since my last post here. A recent upgrade to my Folger i3 is dual extruders. Still tweaking some things but so far I am happy. The image below is from the first try printing the standard cone. You can see some oozing and stringing in the video as I was still playing with temp and retraction settings. Short clip of printing

QuoteWpflum I normally print from the SD. I'm trying to remember if one of the previous prints that failed was from the usb, I'm not sure if I had any but the last one was SD based. I don't have anything on the smooth rod to lubricate, I kinda assumed that since I was using a ball bearinged slide that I didn't need any, would dry graphite work?

Wpflum. Are you printing from SD or USB when your failures occur? I typically print from SD but I do recall seeing a similar jump back when I was using repetier host over USB if the PC got bogged down. Almost like it skipped a few lines of gcode. That only happened a few times though. Was not curious enough to try to track down the issue with a sniffer or anything at the time. Have you used a

Re: Folger Prusa i3 Kit from ebay - 10 years ago

@jjbunn, It does appear from your pictures that things are a bit too hot. A fan blowing on the parts might help. 190 seems a reasonable number for PLA but I would try to confirm the recommended print temps from the provider.

Re: Folger Prusa i3 Kit from ebay - 10 years ago

@jjbunn, Looking at your print I can't see the bulge part clear enough to really make any guesses. One thing I do notice is that your prints have a very wavy look to them. Under a microscope I would guess that you can see separation or poor bonding of the layers. I corrected this problem on my machine by moving the lead screws further up in the flex coupling so that the connection would be less
