I would love to see some pictures of the new extruder drive front end, if someone could take a few and post them.
What part do you mean by the front end?
I have been printing out this mount. [www.thingiverse.com] I don't know if it's worth it or not it's probably going to hang over the front side just as much as the setup I have not using your mounting block I modified.
Can i ask what you might gain by that extruder mount? I was thinking about changing too but mine is running pretty good now. Also The one you are doing is direct drive. From what i've read(I could be wrong) a geared driven extruder is faster then a direct drive. So really your just putting the same thing on that you already have. Now if you put on a ed3 with an external motor drive (something thats not hanging off the x carriage that is gear driven) then I see an advantage. Less stuff hanging way off the x carriage = less weight and vibration. Plus a gear driven extruder for faster prints. Then I see an advantage.

Hmmm still chasing this over extrusion thing. I have narrowed it down to looks like it is over extruding the outside layer. I currently have the shell thickness at 0.6 (went down from 0.8 as a test) in cura. It only seems to do it on small parts. I am printing something that gets bigger as it goes up and the over extrusion goes away as the print gets bigger. I am out of ideas. Temp doesn't seem to change it.

Went to put some lithium grease in the bearings on the Y carriage last night.
I just loosened the rods and backed them out enough to get inside the bearings.
Getting a bit of bearing noise now, hope I didn't bend the rods . Will try to see if I can get them aligned and quiet it down
These LM8UU bearings are starting to get on my nerves. When replacing the y-carriage this weekend, I noticed one of them had worn out a gasket and started chewing into the chrome rod. Replace all of them, ordered a new rod. I have maybe 6 hours on the new set and one of them is already so bad the grinding noise made me kill a print in progress. I think I finally may get around to installing the igus bushings I have (should have just done that this weekend, but wanted to save them for the x-carriage).
Edit: Nevermind, I'm an idiot, one of the nuts fell of one of the corner screws on the heatbed, and the screw was making the noise
I've had exactly the same thing happen, and also got vibration from the clips that I use to hold the glass down to the heated bed. And I think the aluminium bed acts like a big sounding board so things sound worse than they really are. That said, I'd like to hear how it works out with igus bushings, as I've considered doing that as well.
I have 4 RJZM-02-08, purchased here while they were still $5, and just ordered 4 RJ4JP-01-08 from here, but they won't be delivered until mid-November. It's really hard finding the right size, as most of their bushings that have an 8mm hole are 1mm too long and too thick, so you'd have to remix anything that takes an LM8UU to fit.
If these end up having backlash problems like a few people describe, I'm going to suck it up and buy proper LM8UU's at $5-6/piece.
Also, I found a better x-endstop holder - [www.thingiverse.com]

Did you notice any difference in print quality by changing out your lead screw?

Hard to say, I did a bunch of other upgrades along with it, and noticed better print quality. What I do notice with the lead screw is better printer quality... they don't bend like the provided screw rods do, and when I raise by z-axis past the 50% point, the printer doesn't look like it wants to tear itself apart anymore.

I may make the change. But right now its running so good I don't dare touch anything. LOL I also wish the price was less for those rods and nuts.

Very impressed. I have everything calibrated and tweaked. This is my largest and most complicated print yet. The detail is fantastic.
That is pretty sweet. The overhangs that make up the eye sockets look really good too. What layer height did you use?

Thanks! I used 0.25 mm. I had some odd gaps between filaments at the honeycomb holes on the very top of the skull. Nothing serious but not perfect and I'm not quite sure how to fix that. Maybe I just need to put a couple more solid layers at the very top. Just ordered some glow in the dark ABS and will try it again! By the way, what purpose do the add-on cooling fans serve that blow down on the heat bed? Is that so the plastic cools down faster after it has been extruded?

Hi, i'm new to 3D printing and just got this kit in the mail. I started building it, but got stuck at the first step. When attaching the 2020 corner brackets with 4mm T-Nuts and 4Mx8MM Pan Head Bolts, the corner bracket doesn't attach to the 2020 frame piece. The corner bracket falls out and slides around. The same thing happens with the SK8's. Can someone please help me solve this problem?
Thanks.

Hello everyone... I have started working on my printer and I have a couple of questions.
When fixing the rods at the bottom frame I flip the rods and end up with the 2 LM8UU on the left and the single one at the right side of the frame, did this will make difference or can i keep it like that and continue?
As I'm not sure about the bearings I'm wandering if the location of the belt carriage on the bed has to move from the holes closer to the bearing holder (as is on the pictures from the guide) or be put on the ones at the center of the plate?

Sorry that this isn't related to your question, but are the SK8's and corner brackets mounted to your frame? Mine fall out and slide around.
Thanks

I'm just about at my wit's end with an issue I'm having. I built the 2020 and calibrated it a few weeks ago, and everything was working great. Then a week ago I tried to calibrate the stepper drivers with them all plugged in - my probe slipped and I shorted the rightmost pin (+V) on the Z stepper driver to the leftmost pin (GND) on the Y stepper driver. Saw sparks fly and my printer would no longer connect.
So I ordered a new Mega and RAMPS board and 2 stepper drivers to replace the affected components. Got them today and plugged them all in. Now the stepper drivers are receiving signal, but NONE of them work properly with the manual controls in Repetier. Here's how they're behaving:
X: Jerks around when moving in positive or negative direction. Sometimes when I increment by 1, it turns jerkily for a little turn, and sometimes it just buzzes and doesn't move.
Y: For the most part same behavior as X axis. One time I tried to move 10 steps in the negative Y direction and it moved across the entire axis and slammed into the endstop.
Z: Turns loudly and jerkily
When I try to move the X axis .1 steps, it does fairly well. When I try to move it 10 steps, it whirrs and sounds like it should when it's moving, but doesn't turn the motor. Could this be an issue with stepping speed?
I know the stepper motors are receiving some sort of signal since they're all moving in the right direction, just jerkily and intermittently. Voltages are set to .3-.5V and I'm sure there's no endstop problem since I'm setting the stops manually and Repetier doesn't give any endstop hit messages. I also tried reflashing the firmware and reinstalling Repetier, same deal. What could this possibly be? Usually you see problems with one particular motor, but ALL of my motors are misbehaving. Did I demagnetize my motors or get a bad replacement RAMPS or Mega, or could the problem be with the power supply?
