Re: Woodfill - 7 Jahre zuvor

Hi, I printed with bamboofill from colorfabb and it went really well. For the settings I would recommend to go with the suppliers suggested settings. Formbamboo fill colorfabb recomends slightly slower speeds. I think I printed between 30 - 40 mm/s with 215°C and bed at 60°C. The quality was really good and I even sanded the print with very fine sandpaper to get a more woodlike like ( sanding ga

Re: only 1 Z motor turns when running gcode - 7 Jahre zuvor

Fastening the cables really did the trick. Thank you!!

Re: only 1 Z motor turns when running gcode - 7 Jahre zuvor

Hi, it seems that nophead was right. The screws from the power and ground connections were a little loose. After I fastend them I tried a run without the threaded rods attached and everything went fine. I'll try to print something when I come home from work to check if this really did the trick. Thank you for your help! Mathias

only 1 Z motor turns when running gcode - 7 Jahre zuvor

Hi, about 3 month ago I moved, and with me my mendel90. I took very good care it, drove it seperately in the back of my car and made shure it could not move around or anything. Everything went well, but since then my mendel is acting in the most weird ways. The first few prints after the move went absolutely fine. But then suddenly the z-height dropped on the right hand side. So I losend all the

Re: Mendel90 with Inductive Autoleveling - 8 Jahre zuvor

you've got a metallic heated bed, like aluminum, right? The inductive sensors don't work on the pcb heated beds with glass on top.

Re: Mendel90 E3D v6 Conversion - 8 Jahre zuvor

I'm as well highly interested in that conversion. The only real proper guide I've found so far is this one: But whats holding me back right now is that it needs another x-idler. But this would mean swapping hotends would also mean swapping the x-idler and probably some re-calibration, and I really like to avoid that.

Re: Extruder stutters - 9 Jahre zuvor

You were right, it is a wiring issue. But is a kinda strange one: I cant measure a connection for the green wire from the screw terminal of the melzi to the screw terminal of the extruder pcb. But I can measure connections between the melzi connector and the pin in the female extruder connector and between the screw terminal of the extruder pcb and the pin on the male extruder connector. So it se

Re: Extruder stutters - 9 Jahre zuvor

Ok, so my gears are not worn out then. I'll made a video to show you the stuttering: It even occurs if no filament is loaded. When I made that video I was able to turn the wheel by hand and extrude without a problem. Could there be anything wrong with the motor or is it possible that this is a wiring issue?

Re: Extruder stutters - 9 Jahre zuvor

After a month of successful printing, the stuttering is back. And now It seems to come from the gears. After I checked the gears and repositioned the small one, it extruded again. But after homing all axis the stuttering was back. When I changed the position of the small gear again, it extruded fine but never managed got get beyond the homing. It seems that a "motors of" command or something like

Re: Extruder stutters - 9 Jahre zuvor

I had a look at the speed and you were right, at 60mm/s it was not an issue at all. Right now it's printing again. Thank you very much!

Re: Extruder stutters - 9 Jahre zuvor

Ok, I disassembled everything, cleaned the bolt and readjusted the extruder idler wheel. I tried to clean the hotend with a "cold pull" at 80°C as well, but couldn't no The stuttering is now gone but it still makes cracking noises after the same amount of filament (35mm) extruding. I tried a new spool of PLA and it is the same. Even higher temperatures like 220°C didn't change that. I must come f

Extruder stutters - 9 Jahre zuvor

Hi, I've got a problem with my extruder, it stutters. Yesterday I noticed some serious underextrusion and wanted to check the the e-steps, so I tried to extrude 100mm of filament (3mm PLA from print2beta at 200°C). Shortly after the extrusion started I noticed some stuttering noises. It extruded roughly 35mm of filament before the stuttering. While stuttering no filament is forced in the extrude

Re: Mendel 90 initial testing. Extruder feed not working. - 9 Jahre zuvor

I think pronterface has a little bit of trouble working with decimal places in values. The standard is for example something like 185.0 degrees for pla. This throws the exception you're talking about. Try full numbers like 185 and it should work. Same is for the length of the filament that should be extruded. I hope you understand what I mean.

Re: ptfe tubing pulled inside the wades block - 9 Jahre zuvor

@bastard : alright...the german precision....should have known that as a german I found a reseller in the UK: but for germany it looks indeed quite complicated. even distributors like farnell only have tubings with 3.76 or 3.93mm available, but would it really make a difference? I think since this is not really a bowden extruder and the filament diameter can vary anyways something like 3.76 or

Re: ptfe tubing pulled inside the wades block - 9 Jahre zuvor

@bastard : I suppose you are from germany, so you can order a spool of ptfe tubing with 3mm - 4mm inner diameter right here:

Re: ptfe tubing pulled inside the wades block - 9 Jahre zuvor

Hi, you could use something like a stopper. I made a quick thing in tinkercad: I did not print it yet, but it should work. Maybe you need to drill out the hole for the filament a bid and adjust the size of the tubing with sticky tape. let me now if it worked out for you. Edit: To be on the safe side: print a few in one run. Since it's a fairly small part it could use some time to cool betwe

Hi, how tight are your belts? The manual says your supposed to hear a note when you pull them. Youncamn check your pulleys as well, mine became a bit loose in the beginning.
