Re: Große oder kleine Pulleys? Vor und Nachteil? - 10 Jahre zuvor

Ich hab gerade von 16er HTD pulleys von mädler auf 10er umgestellt und muss sagen dass es ganz schön was gebracht hat. Vorher konnte ich meine Achsen noch von Hand festhalten, jetzt ist dazu richtig kraft nötig. Ich hab auch seitdem nie wieder einen Schritt verloren, wenn z.B. mal das Filament irgendwo geklemmt hat. Die Auflösung ist auch nochmal ordentlich gestiegen, woei ich aber sagen muss das

Re: Trapezmutter TR8x1.5 mit Bund gesucht - 10 Jahre zuvor

Ich muss schon sagen, dass ich immer noch ein wenig skeptisch war.... Aber ich hab grad mal ein bissl gerechnet: eine m8 Unterlegscheibe hat eine Fläche von ca. 40mm² , also 0,4cm², (reell bedeutend weniger, da die Mutter nicht überall auf der Unterlegscheibe aufliegt), bei einer maximalen Zugfestigkeit des Klebers von 148kg/cm² sind das immerhin 60 kg, die ich im äußersten Fall auf eine Mutter

Re: Trapezmutter TR8x1.5 mit Bund gesucht - 10 Jahre zuvor

Hab ne Spezialkonstruktion.... Es liegt wirklich meine komplette stählerne x-Achse inkl. Extruder auf den Bünden der beiden Muttern auf. Die X-Achse bewegt sich ja über die z-Gewindestangen in z-Richtung rauf und runter. Damit ich zum Arbeiten am Extruder oder an der Achse die Möglichkeit habe, die Achse hochzuheben liegt sie mit möglichst wenig Spiel auf den Bünden auf. Wäre kein Bund da, würde

Trapezmutter TR8x1.5 mit Bund gesucht - 10 Jahre zuvor

Hallo! Hat jemand ne idee wo ich eine TR8x1,5 Sechskantmutter mit Bund herbekomme? Ich finde nur normale Sechskantmuttern ohne Bund. Leider liegt im aktuellen Design meine x-achse auf dem Bund auf, so kann ich zum arbeiten einfach die Achse hochschieben. Anschweißen wäre nur ne notlösung, da sich evtl. was verziehen könnte und der Bund sehr gerade sein muss, sonst bekomm ich z-wobbling. Jemand

Re: What's going on with ABS is mixed with acetone (chemically)? - 10 Jahre zuvor

As you said, It is a solvent. Think of the polymer chains like fresh cooked spaghetti, they curl and wind and hook to each other physically, not chemically. (Actually some of them really stick to each other in an organized way, which is called semi-crystalline zones, you can observe that with spaghetti too, but its not too important here) If you add lots of water (solvent) and stir a little,the

Re: Thermocouple shows 500°C - 10 Jahre zuvor

OK, I found out that it really is just the pins.h problem. My opinion is that pins.h is VERY confusing because of the many un-sorted ifdefs that are stacked and not very well organized. Since I just replaced EVERY #define TEMP_0_PIN X with #define TEMP_0_PIN 3 in the whole file and after that, it worked it could only be this issue. However I still have not found which #define TEMP_0_PIN it real

Result was the psu switching to red every time I printed ABS with it... however I only used the 12v rail. Possible that when applying load to the 5V rail the 12V get mor

Thermocouple shows 500°C - 10 Jahre zuvor

Hi! I bought a reprap world thermocouple K type from E3D for my shiny new e3D hotend and hooked it up to my ramps board. Unfortunately the temperature shown is 500°C, sometimes 499°C.

Re: Looking for ways to make a Filament feed sensor. - 10 Jahre zuvor

I had this idea for mendel extruders, dont´t know if deltabot extruders are any different, since i am lacking deltabot knowledge: Usually you drive your filament between the hobbed bolt/wheel/whatever-drives-the-filament and a bearing. The bearing only rotates when filament actually is transported. Bright marks on the bearing can easily be detected as moving with a photodiode/resistor.

Re: endstop placement and axis directions - 10 Jahre zuvor

That was the first thing I tried, but then i ran into trouble homing, since there was no endstop where the bed homed to. So I had to connect my endstop to y max and do everything else software-wise. A bit messy. To make confusion worse, Y and X axis were swapped name-wise in the beginning on my printer... Autobedleveling made homing even more confusing and this is why I decided to do it proper.

Re: Proper shape fotr extruder tip? - 10 Jahre zuvor

I really think that tip geometry DOES matter. So does tip roughness. Remember that the extrudate is not only put in place by the nozzle, it should ideally be squezed by 30-40% of its diameter by the tip in order to produce the optimum shape of extrudate and better layer adhesion. (Thats how we achieve layer heights < nozzle diameter)... So, yes it does matter. Take a look at E3D´s nozzles, I

endstop placement and axis directions - 10 Jahre zuvor

Hi, my self-built printer needs the endstops to be put in place. Basically it´s a little like the latest prusa, but made of lasered steel for maximum rigidity and a LOT of modifications. Here´s a quick drawing: The print bed can move 400mm in Y direction so it does not matter in which direction the print is made, mechanically. At the moment I have just MIN endstops, which should be enough, b

Re: DRV8825 tiny trouble - 10 Jahre zuvor

Ok, this brings me back to my first assumption, that step size might be involved: I just tried repetier firmware instead of marlin, and E0 works fine with the drv8825.... Even more strange???

Re: DRV8825 tiny trouble - 10 Jahre zuvor

It's just a test because I am running out of ideas.... This is such a strange issue... I can hear the stepper making a sound while trimming the pot but no movement on E0... I tried lots of drv8825s and lots of stepper motors. They all work on xyz but refuse to work on e.... When i use a random 4988 it works everytime, even on e0. Strange, right?

Re: DRV8825 tiny trouble - 10 Jahre zuvor

I have not yet found a solution for this. But I have an idea. I'd like to swap the E0 driver to E1 and tell marlin to use extruder #1 instead of #0....maybe that fixes it... I somehow assume that RAMPS is the source of the trouble. Do you think it's a big deal to tell marlin to use E1 instead of E0 everytime?

Re: Servo wobbling, basic electronics question inside .. Help needed - 10 Jahre zuvor

you had the same kind of trouble? I am thinking now that this is some RAMPS related issue since it is very well possible that the servo lanes are too close to the stepper lanes on the board, causing interference... RAMPS has so many issues, a 1.5 would be a really good thing. I had trouble with the PTC fuses, the MOSFETs get too hot and some other minor issues. Since RAMPS is a very commonly use

Hi! I am just wondering if I could use someone's settings for this combination as a base for my own settings. Also, what would be the maximum speed people had successful prints with? Btw, I finally managed to fit the hotend to the extruder carrier together with the extruder... Did you also have a hard time to assemble it because the E3d hotend is so big? Thanks, Phil
