Thank you all for sharing your opinions and experiences. I decided to keep the filament and if I do run into problems, I'll try drying it.by Rotz - General
There are those desiccant bags you shall not eat inside all of them. Regarding the other aspect, they are all different: one was perfectly sealed, one has a hole in the sealed bag, another one isn't even sealed. I wonder why nobody seemed to notice/care..by Rotz - General
The diameter seems to be ok from what I measured. So you don't see a problem in not vacuum-packed filament alone?by Rotz - General
Well, basically my question is in the subject.. This is my first batch of PLA so I don't really know how I should react to that. Is it that big of a deal due to the hygroscopic behavior? I think the main problem is that nobody can tell how long it has been in the shops storage and how long it has been exposed to air. What would you do in that case? Thanks, Rotzby Rotz - General
falls du ramps benutzt, könnte es sein, dass du die jumper für das microstepping vergessen hast. das sind die pins unter den pololus, dort am besten jeweils alle 3 rein, dann ist 1/16 microstepping aktiviert, und dein problem mit den verfahrwegen und dem extruder sollten.behoben sein. du wirst dich dann auch über einen erheblich leiseren drucker freuen 6 endstops brauchst du eigentlich nicht, duby Rotz - Projekte

They differ from the single sheet part. Here you can get the original prusa i3: https://github.com/josefprusa/Prusa3/tree/master/box_frame Also, you could look at the forks, perhaps you find something even better.by Rotz - Reprappers
Hallo Pete, In Cura könntest du auch mit CTRL + E die Experteneinstellungen öffnen und Spiralize the outer contour auswählen. Allerdings gibt es da nicht soo viele Einstellungsmöglichkeiten wie in Slic3r. Außerdem hab ich selbst damit noch nichts mit spiralized contours gedruckt. Viel Spaß weiterhin mit deinem Drucker /Edit: hab eben gesehen, dass es im neueren Slic3r (1.0.0RC3) die Einstelluby Rotz - Allgemeines
They can get a little warm of course, but hot is indeed an indicator of to much current. I don't think there is a exact voltage value for the steppers, I'd just stick with the method of increasing the current (clockwise) to where the motor just moves and giving it about 1/8 of a revolution more. But in fact, I meant the stepper drivers, i.e. the little circuit boards, if they have any heat dissipby Rotz - Printing
Vllt zu geringer Motorstrom am Extruder-Poti eingestellt? Welchen Extruder hast du denn? Bei zahngetriebenen bitte darauf achten, dass das am Motor befestigte Zahnrad wirklich fest hält und der Anpressdruck zum hobbed bolt ausreichend ist. Wenn da mal irgendwas durchrutscht, wäre das eine Erklärung für das nicht geförderte Filament. Außerdem möchte ich dir noch den Hinweis mit auf deinen Weg gebeby Rotz - Allgemeines
I wouldn't exactly say your x/y axis is perfectly fine, as it seems like skipped steps in there: (upper part; undercut is becoming a overhang). This can be due to insufficient cooling of the stepper drivers (Housing? Heatsinks attached? Current set to correct value and not too high?). Or maybe your belts aren't fastened. Also, did you check if your e-steps are set correctly? It seems like a bitby Rotz - Printing
The tutorial looks awesome. Very detailed and a lot of pictures. Well, the software part might be not detailed enough As long as you order parts for a box frame, it should work (but look out for which threaded/smooth rods are necessary, 8 or 10 mm are possible; also I'd go for at least abs-printed extruder parts). Although there's no way in telling what the print quality of those parts will beby Rotz - Reprappers
unfortunately I'm not entirely sure, if I'm addressing the right problem, but could you please try to move the axis away from the triggered endstop (kidding ), trigger it by hand and then try to reconnect. there is a safety mechanism, that when a endstop is triggered unexpectedly, you have to trigger it again in order to tell the machine everything is fine again - then you might be able to reconby Rotz - Printing

Glad you're getting involved! Examples for diffenences might be something like how rigid is the mechanical construction is (plastic parts which are mechanically stressed by forces and therefore reinforced as well as overall; compare box frame and sheet metal frame), how fast is the printer (more rigid -> faster, I'd assume), difficulty of assembly (look at the bom of mendel compared to prusaby Rotz - Reprappers
I do really love your idea as I've already been looking out for exactly that. In fact it's like some kind of dream, your project is even better than what i've hoped for (tagging, the looks, your attitude ). Unfortunately I can't really contribute (except for donating - which you don't accept atm - and expressing my respect and gratitude) with my set of skills but I will ask people who might.

here are some pictures of the motor: Fully assembled. Four phases and a small part of the coil visible. Housing disassembled, rotor still inside. Housing and rotor disassembled. Housing and rotor disassembled. I (again, unsuccessfully) tried to get out the stator. Is there a trick to do that or might it be glued to the metal housing of the nema17 motor?

Well, first off, I'm no expert in electricity or anything, but could this be induction due to cables running to close to each other? Do your e- and x-motor cables run alongside very tightly in a part of your build? I must confess, I don't know if it's even possible that it's that. When those blobs you mentioned occure, does you x-axis slow down or something?by Rotz - Reprappers
Have you installed the jumpers underneath the stepper drivers? This regulates the microsteps, which would explain your printer moving "way to far". I experienced (but not really understanding) also loud motors and movement only with low mm/s (at least in pronterface, didn't compare) when facing this problem.by Rotz - Reprappers
Hi, well, this is my first post. Mainly thanks to you, the community, as you always had the specific problem already covered. That helped me out a lot - thank you. Now I'm facing a problem, and I hope anyone has already a solution for it. I'd like to rewire my steppers but after disassembling, I noticed that they weren't just connected to a small pcb or something (I don't really know what I expeby Rotz - Stepper Motors, Servo Motors, DC Motors
