version 0.1 of hotend probe mount for rostock max - anyone have an idea if filament diameter or some sort of vibration is causing these artifacts? I’m still learning the non-intuitive delta printer wonkyness of print problems…
Sliced in Cura, which I’m now starting to see why people like so much. The blobbing / retraction issues I had were traced to the new version of slic3r, the older 0.9.9 eliminated the issue.
Backlash has been minimized, and I think I’ll have to upgrade the effector linkages to make it any better. Besides magnetic balls and rods, does anyone have a favorite linkage? The arms of the newer seemecnc rostock aren’t crappy anymore, but the slop in the aluminum universal joints is a bit rubbish. Shimmin it also doesn’t seem a practical solution…
Forgot to mention, @Sanjay_Mortimer 's E3D made a huge difference in retraction / print quality as well. The PTFE tubing they use in the bowden kit is very nice - eventually this might be a kraken machine!
To further elaborate, I’m talking about the banding/ offset bulges that occur low in the print, and what might be a separate issue of over-extrusion at higher layers
I recommend the “Traxxas 5347 Rod Ends with Hollow Balls Large Revo” linkage, they come in a 12 - pack for around 10$. Carbon rods 5/4 mm od/id and m4 set screws glued with epoxy. Screw the set screw all the way into the rod end otherwise you may get some play. I have used this for half a year on my delta without issues.
Difficult to determine the cause of your problems, my best guess is that you still have some play in rods or carriages. Have you tried reducing acceleration and jerk?
Thanks for the tip @Stefan_Langemark - would you install these on the stock effector and carriages? Seems a drop in replacement, if the same rod can be used as the ball axles…
But familiar with printing delta, but it’s that ABS or PLA? With ABS, I get that “registration” when I print pillars like that, then connect them, as the pillars warp and lean a bit while printing, so they are mislocated slightly when they are all bridged together. This would not explain why you have the same effect prior to the pillars though…
It’s ABS, but the columns print and stay aligned just fine. Just weird ribbing / corners on the early levels. I think I might need to adjust my printer radius? (the concave/convex correction value.)
