IMO you would be better off designing a motion system with less backlash before worrying about stepper resolution.by jzatopa - Mechanics
It looks to me like you have a z-wobble. Nothing in your settings can fix a z-wobble. You need to decouple your Z axis lead screw and nut from your gantry and/or decouple your lead screw from your stepper. From looking at your picture the first step I would take would be to replace your solid couplers with some aluminum helical couplers.by jzatopa - General
AndreyR that is awesome. I would love to play with a cement printer. Will you be releasing your design?by jzatopa - General
Quotegreenman100 Quotejzatopa I am very interested in the PICO hotend, I just wish they would give more info about the melt zone. Does anyone know if there are beta testers out there that have reviewed it? There are - they're under NDA and not allowed to post openly. E3D all the way, in my opinion. If the beta testers are having positive response B3 should be having them share their experiencby jzatopa - General
Have you made sure that the heat is the problem 100%? What material and brand of filament are you using? Is the hotend jamming or is there something else causing the extruder to be unpredictable? One way to trace the problem is to remove the hotend and see if the extruder will feed filament properly. It will help you narrow down the exact location of the problem.by jzatopa - General

I have been considering a screw design as well, part of the reason I was interested in screws was the print quality of the aluminatus. I have even looked into using PBC simo assemblies but they are way to expensive to be viable, so I am going a different direction. Recently I had a talk with another printer builder and he told me that I wouldn't gain much over belts as long as the rest of my prby jzatopa - Extruded Aluminum Frames
Usually when I have this problem it turns out to be a lose pulley. Make sure all your pulleys are securred properly.by jzatopa - Printing

Guys, I just made a quick video on how to fix filament that doesn't properly meet size and shape specs. How to fix poor quality filament I thought it would help some of you who might be stuck with a bunch of junk filament. The easiest fix is to buy good quality filament in the first place.by jzatopa - General
Have you tried printing in a heated chamber? You can use an oven bag or cardboard to build a temporary one.by jzatopa - General

ZATOPA.COM is now open for business. ZATOPA.COM understands your needs as a 3D printer. This is because we are a maker owned company based in Chicago IL. providing the highest quality filament available. ZATOPA.COM has sourced all our filament within the United states because we think it is important to shop locally first.

For those of you who are interested I just did a review of the carbon fiber impregnated PLA, you can check it out here.by jzatopa - General
I think this might be worthwhile. I would like to see a prototype that demonstrates the improvement over an open loop system.by jzatopa - General
I'm curious if you guys measure your test print when they are still hot/warm on the bed or do you let them cool 100% before measuring? When printing ABS there is shrinkage of the part once it's cooled. I would think that you want your final part to come out to the right dimensions when cooled but that would mean that you would have to calibrate your printer to print just a slightly bit larger.by jzatopa - General
Komb, that is awesome, you've got a big win right there. The prints looks good. How is the backlash and wear resistance?by jzatopa - General
Gsport that looks like a very worthwhile design. I would think that the glass could also be replaced with a ceramic tube as wellby jzatopa - General

Traumflug, how is the release of three new filaments not development in the 3D printing space? I think you are being a bit myopic. New materials open up a whole new world of what is printable. I think matts proposed change to the forum rules is a much closer to what is needed but I would remove the crowdfunding aspect. A large part of reprap is crowdfunded now, which I will admit falls into aby jzatopa - General
