Thanks guys. I was actually able to just pull the ptfe tube right out of the barrel without too much trouble and then I was able to pull out the clogged PLA from the ptfe tube.by Danmst3k - Printing
On my Prusa i3 2020 I there's PLA fillament stuck in the barrel that goes to the hotend. My print quality went downhill so I tried running the nozzel at a higher temp and I think that's what caused the PLA to melt in the barrel. Turns out my nozzel was partly clogged. Any thoughts on how to remove the PLA without messing up the PTFE tube inside? I whatched some tuts on youtube but they didn't deaby Danmst3k - Printing
Quotemel0n Quotewderoxas My endstop was at the head cause i was using Auto Bed Levelling. There's a servo just left of the fan to place that endstop into position during Z homing or auto levelling routine. Oh cool, does it still function as the x endstop? QuoteDanmst3k Thanks, Mel0n! The top on the left cube was because I accidently pushed it in with my finger while it was still warm, lol. I'mby Danmst3k - Prusa i3 and variants
Thanks, Mel0n! The top on the left cube was because I accidently pushed it in with my finger while it was still warm, lol. I'm printing PLA for now using the makerbot fillament from Staples. I think it's pretty good stuff. Seems ok so far. Not cheap but it's nice to just go to Staples and buy some. I think I could definitely use a fan though.

Thought I'd post a couple photos of some tests. Pretty happy with the quality of this printer so far. The cubes are 20mm and hollow with only 1 layer wall thickness. The one on the right was printed first and is totally smooth. I was having issues with a ripple pattern previously so I tweaked my stepper drivers and that was the result. The weird thing is the cube on the left was printed pretty muby Danmst3k - Prusa i3 and variants
Thanks for the info, Mel0n. I agree about the bushings. I think some of mine have square bearings in them. If I could just get the X to be as smooth as the Y, that'd be great. I put the tensioners on the belts and I though it'd make a big difference but it didn't, for me anyway. MUST HAVE PERFECTLY SMOOTH PRINTS!!! lolby Danmst3k - Prusa i3 and variants
Thanks widespread. My X and extruder motors seem to be slightly hot. The X did get cooler when I tweaked the pot to make it quieter. I'm thinking maybe the extruder stepper is also vibrating, could explain the why I'm still getting ripples. I really need to throw a meter on these to check whats up. I haven't tried any large prints yet. Don't know if I can handel a mistake halfway through lol.by Danmst3k - Prusa i3 and variants
Got my i3 2020 up and printing about 5 days ago. I'm very happy with it so far. I'm still in the tweaking faze and have been doing test prints. I printed the 20x20x20 cube and I'm getting a ripple pattern on all of the sides. There's 5 ripples on each side on a 45 degree angle. I noticed my X stepper was making a lot of noise/buzzing when it moved and that would vibrate the whole machine to someby Danmst3k - Prusa i3 and variants
Yay! My printer for the most part, works, X axis and all! I was able to air print the 20 mm test cube last night. The only glitch was the lcd screen had garbled text on it halfway through the print. Not sure what that was. Also, I haven't checked my voltages for the steppers yet. I felt them and the X axis was slightly warm but not too bad so they might be ok. Don't know if it would get hotter foby Danmst3k - Prusa i3 and variants
Almost done with my Prusa i3 2020 build. It's my first 3d printer. I noticed in the build pdf manual that the X Stepper is plugged into the ramps reversed when compared to the other steppers but there isn't any mention of it in the manual. I also have read about people having problems with the X stepper direction and endstop. So, I'm thinking I'll do the same and see what happens with it reversedby Danmst3k - Prusa i3 and variants
