Sorry for bumping such an old thread, but I had exactly the same issue this weekend. Did the FJA13009TU solve your problem? Thanks.by sombetzki - General
Been busy this week, but I checked also for backlash on my z-axis. Found out the bottom lineair bearing on the right side also had some clearance, so I printed this parts at my office; Only fitted on one side because of the z axis end stop on the left side which made it impossible to fit one, but my prints are way better! Both printed at the same settings I also printed another bunnyby sombetzki - Prusa i3 and variants
Printed a low poly Stanford bunny for a colleague and I noticed that the wobbles aren't on all facets... Maybe this will help troubleshooting. I added pics below. I checked if it wasn't the lighting that made it look like some facets are flat, they really are good! It's hard see, but some of the polygons are way flatter than the rest... Any idea how this is possible? The flat ones are howby sombetzki - Prusa i3 and variants
Both Z-Axis motors don't work? You could connect the wires to a different axis on the controller board and see if they work. If so, then your controller board has a problem.by sombetzki - Prusa i3 and variants
Quotebigfilsing That's what commonly known as a linear bearing or LMU8 and certainly the one at the front in the video has way too much play/clearance ( te veel speling) they are normally quite loose because we want a friction free travel on the rods but what you have there is a problem. Most of the LMU8s for 3D printers are quite cheap low quality ones but still work well if lubricated properlyby sombetzki - Prusa i3 and variants
Hereby links to my gcode;by sombetzki - Prusa i3 and variants
Yes, it happens on every print. "For example what happens when you print a 20mm test cube test cube" "or when you print this linkling" (didn't use enough glue on the build plate, so it came loose) Can post the g-code here if you'd like, but I found somehting else... When the bed moves towards me it's fine, but when it moves back/away from me you can hear it make a ticking noise. I checked ifby sombetzki - Prusa i3 and variants
Yes, still have the issues. Tried a lot of things, also changed to a different filament. Changed e-steps, filament size in my slicer settings, flow rate. Don't think it has to do anything with the extrusion anymore. And yes, all the hephestos printers on youtube have perfect print results, much better than mine. Starting to think it's just bad luck. Maybe I need to take it apart and rebuild itby sombetzki - Prusa i3 and variants
Hi, The electronics on my printer are as following; Freaduino Mega 2560 v1.2. Design based on Arduino Mega 2560 + Ramps 1.4, with heatsink on the MOSFET of the hot bed. Stepstick Drivers A4988 with 4 layers and improved heat dissipation to avoid overheating & heatsinks for attached drivers. - The model is the Marvin of 3dhubs.com It isn't faceted at all, I've seen so many prints of it anby sombetzki - Prusa i3 and variants
Hi Bking1340. Haven't tried printed a different color filament with the same settings. Will do and let you know! Thanksby sombetzki - Printing
Quotebigfilsing You would do well to give more info what controller are you using what firmwear what slicer what software do you use to print As the deviation is uniform ( not in one particular axis/plane) i think you need to look closely at your slicer/gcode Printing at 0.1 layer is on the limit of reprap printers anything lower is delving into uncertain territory Just for kicks try printiby sombetzki - Prusa i3 and variants
Quoterhmorrison Z-wobble Thanks. Will read those topics. I already changed my threaded rods for the z-axis for other ones since they were really wobbly. Result stayed exactly the same, no difference at all, so I'm thinking that it isn't the problem. Or there must be a different way to fix z-wobble Link to video with old curved threaded rods; Link to video with new straight (better) threadedby sombetzki - Printing
Just build a Prusa i3 Hephestos printer this weekend and my layers are wobbly in a consistent way.. Can anyone explain the reason? Thanksby sombetzki - Printing
I've got the same issue it seems; Did you find a solution to this problem?by sombetzki - Prusa i3 and variants
Hi all! I've got a Prusa i3 Hephestos which I build this weekend. All works well, but I'm not satisfied with my print results. Looks like the printer makes vertical waves. This image explains the issue; This is printed at 0,1 mm layer height at 50 mm/s. Also made a print at 0,06 mm which has the same issues, just on a smaller scale. Can someone tell me how to improve my prints and what to dby sombetzki - Prusa i3 and variants
