1. I redesigned the carriages and made some plastic pieces to transform the fishing line idlers into belt idlers. I aldo use an efector designed by me. 2. I dont have vibration problems.

I have a problem that I haven't been able to figure out. When I send "G28" to my Mini Kossel, then the three carriages should all move up to the end stop. However one of the carriages (driven by the y...

Hi I thought (and maybe wrongly) that taking the play out of cheap bearings with some axial tension was part of the design..... Bob

@ Nicholas I tried to eliminate play by press fitting the aluminum tube in the shoulder and machining a land on the aluminum tube for the bearing inner race to rest against. The installation is...

@Dannydefe: Could we not just integrate the functionality of the aluminum slug into a printed part? My other concern is with the 6702s. They are cheap enough but 4 times the cost of a 608. That one...

Re: LISA Simpson
Another idea: Design some thing like what Nicholas suggested, a detachable bearing pocket. But the pockets for both sides are closed, this will trap the shaft. To save weight, glue the bearing pocket...

Looks good Hade. I have this system on my old Uventorbot printer...It adds weight to the total machine weight... But why did you use that in this setup? Just to test or is there other reasons ?

Thanks HaDe! Not sure how i missed that. :) I looked into it a bit, but i cant find info on suggested material to print parts in. Is ABS prefered, or is PLA sturdy enough? Did you print your own? What...
View ArticleRe: 2020 Bowden Drive extruder
I printed mine in PLA but don't remember the exact settings (50% - 0.2Z is what would use, too). I wouldn't worry about durability of the flex hinge too much, it will only be adjusted once and barely...
