? My firmware should work as is with the screen.
If I did t have the library installed correctly in arduino IDE, it would give an error when attempting to compile, right?
It “chirps” when I push the bomb/button…

Can’t get the LCD to work, but we won’t worry about that at the moment;-). Rebecca wishes to THANK all that have provided input on her build! I say THANK YOU too!
Damn your “exceeds file size” parameters!!! LOL!
Fine:o)
We uploaded to Youtube:o)
Enjoy! Lots of tweaking to do. Yes, we know we should have printed a smaller item first. But, Hey! We say, go big or go home;o)
Cheers,
Jon and Rebecca
Congrats!!! Did you watch it print the entire time?
Is anyone use Simplify3D with their MP3DP? If you are and getting great printing results, would you mind sharing screen shots with me of your process edit parameters.
Or if you are using Repetier and are will willing to share your settings it would be appreciated.
We have found it a struggle to get a good looking print from the MP3DP yet unless we up the extrusion multiplier by 140% We are assuming that we are missing something. We are run good quality PLA 1.75 with a .4 nozzle.
Any help would be appreciated.
Thanks,
Jon and Rebecca
double check the filament size in your slicer, you are using 1.75.

Good Job, Jason:o)
Ryan- Yep, that was the first thing I checked. I think I will take some screen shots tonight and post them here to see if you guys see anything that looks funny.
I’ve actually tuned mine down by about 5% from the 200steps/mm that is in Ryan’s firmware. I followed this guide:
http://reprap.org/wiki/Triffid_Hunter’s_Calibration_Guide
Except when he has me scale that print up to 250% and print at 95% infill, that takes hours, so I scaled it to 250% x,y, and 50% in Z.
I’d start with the procedure in 4.2: http://reprap.org/wiki/Triffid_Hunter’s_Calibration_Guide#Measure
If that’s not coming up with something near 200 steps/mm, or if it’s inconsistent, then something is probably wrong with the printer, 140% is a lot off, and since it’s under it could be (brainstorming here):
- hot end not hot enough
- idler not tight enough. Mine is hand tight. A little tighter than hand tight shouldn’t hurt though.
- Stepper skipping, maybe due to stepper driver calibration (If you bought them from Ryan, I think he sets them for you though).
I wouldn’t think a bad wire would cause it, because it wouldn’t move at all, or it would have a temp error.
I wouldn’t think a loose extruder gear would cause that either, because once it slips, I would assume it wouldn’t grip until you tightened it.
If the measurement procedure comes out to near 200 steps/mm, then it might be the slicer. I’ve never used simplify 3D.
There are a bunch of screen shots of settings for Slic3r here, although they are a little slow:

I’ve changed a few things, but I can’t remember what off of the top of my head. I can send them to you, if you like. I also have some cura settings that work ok.
I wouldn’t think a loose extruder gear would cause that either, because once it slips, I would assume it wouldn’t grip until you tightened it.
I found that it would continue, just skipping occasionally. I actually ended up calibrating mine by asking for 100mm of extruder feed, then tightening the screw just until the skipping stopped. The looser it was the more it would skip, making little clacking noises for each skip. When it was tight enough it would move quietly, and the next 100mm test came out at something like 98mm of actual filament pulled through.
What are you guys using as your default printing speed? And then what percentage of that speed for outline underspeed and solid Infill underspeed?
It should all be in the repetier basics.
Start with 30mm/s, under speed the first layer 50%, outer edge 90%.
Once you get a good handle on things you can start bumping these all up.
We have not tried Repetier yet. Think I will see how it prints on it and compare. Will report back…
Ok…tried repetition, pretty much same results without ramping up extrusion.
Tried fresh filament, same results.
Decided to run a 100mm extrusion test. 79mm of filament moved through the extruder.
I have checked under the drivers to make sure that all three jumpers are in place. All three are there. So can I assume that I need to make a change in the firmware for the extrusion??? This might be causing me whole problem…
yes setting the firmware would be best…but…I have a feeling your nozzle might be clogged. You are using all my stuff, so the settings should be okay.
Or the tension is not high enough on the drive gear.
So lets go in steps just in case.
-
PLA correct? What brand, and what extruder temp, is the little thermistor in the hole?
-
Set it to extrude and try and hold the filament from feeding through.the tension should be high enough to make the motor skip steps, not just filament sliding through. If it is only slipping tighten the screw on the lever to increase tension, if this is good step 3.
3)tell it to extrude and get a picture of it extruding in mid air, post it here and we can see if you are clogged, luckily pla is easy to unclog usually.
do you have a .5mm nozzle on there? try a print again with the nozzle set to .5mm
