05:19 AM Tom_L: heard of it but know little about it
07:09 PM zhanx: Evening
07:10 PM zhanx: Rue this bed setup has to go, I am printing a new thing for it
07:11 PM zhanx: https://www.thingiverse.com/thing:449055 <=- I am printing at 5 perimeters 50% infill, so its stiff
07:12 PM zhanx: next I am making a 200x200mm plate to sit on top of it
07:12 PM zhanx: then changing to a mirror instead of glass
07:17 PM Tom_L: how is mirror better than glass?
07:18 PM rue_mohr: flatter so it seems
07:18 PM rue_mohr: the linear bearings suck
07:19 PM Tom_L: trying to set up this damn phone
07:19 PM rue_mohr: I would like to suggest against what you have now, BUT YOU DIDN"T SEND ANY PICS
07:19 PM rue_mohr: meh
07:19 PM zhanx: rue_mohr, i want to print bearings
07:19 PM zhanx: I have the stock options
07:19 PM zhanx: 3 point linear bearings
07:19 PM zhanx: it wobbles to mucj
07:20 PM zhanx: much
07:20 PM rue_mohr: the other error is 2 parallel rodsl ike that
07:20 PM rue_mohr: they bind
07:20 PM zhanx: I will fix the binding, I have a mic and time
07:20 PM rue_mohr: no, temp change, you do NOT put two 3-point linears in parallel
07:21 PM rue_mohr: but evryone does it and says they made it work
07:21 PM zhanx: well i can use it as 3 print system also
07:21 PM rue_mohr: the second side should floa....
07:22 PM rue_mohr: did you see the pics of my upgaded system?
07:22 PM rue_mohr: http://ruemohr.org/~ircjunk/projects/reprap4/p1100020.jpg <-- 3 point bearings
07:22 PM rue_mohr: it goes on the reference rail
07:22 PM zhanx: k looking
07:23 PM rue_mohr: http://ruemohr.org/~ircjunk/projects/reprap4/p1100041.jpg
07:23 PM zhanx: those the bearings you had me buy?
07:23 PM rue_mohr: http://ruemohr.org/~ircjunk/projects/reprap4/slide.htm
07:23 PM rue_mohr: thdamn
07:23 PM rue_mohr: t
07:23 PM rue_mohr: sklasdfuhkasdrf
07:23 PM rue_mohr: http://ruemohr.org/~ircjunk/projects/reprap4/p1100118.jpg
07:24 PM rue_mohr: the other side gets a U , which means that it doesn't matter if the rods are 0.5thou or 10 thou out, no binding
07:24 PM zhanx: well that first link i sent is about done printing
07:24 PM rue_mohr: http://ruemohr.org/~ircjunk/projects/reprap4/p1100122.jpg
07:24 PM zhanx: ok i see it
07:25 PM rue_mohr: the general communitry does not know how to properly do linear bearings
07:25 PM zhanx: I also need to have a removable build plate
07:25 PM zhanx: getting parts off is a pita sometimes
07:25 PM rue_mohr: http://ruemohr.org/~ircjunk/projects/reprap4/p1100169.jpg
07:25 PM rue_mohr: ya dont NEED the holdown springs
07:25 PM rue_mohr: I been printing on my other one for a year with none
07:26 PM zhanx: spring have been my bane since i added them
07:26 PM rue_mohr: I'd like to see what you did
07:26 PM rue_mohr: BUT I CANT SEE IT
07:26 PM rue_mohr: :/
07:26 PM zhanx: ok tomorrow I will get pic, as its covered in tape and printing
07:27 PM zhanx: but http://ruemohr.org/~ircjunk/projects/reprap4/p1100169.jpg <- is really really close to what i have with thumb wheels and the linear bearings
07:27 PM zhanx: we talking about swapping out those linear bearing before
07:28 PM zhanx: wow, my mind is all over the place
07:29 PM zhanx: rue, i am gonna install that sub bed and see how it works, and
07:29 PM zhanx: a few other mods i want to run by you
07:30 PM rue_mohr: I'll try to finish the gearbox for hackaday, and enter it into the comp.
07:30 PM rue_mohr: a 2:1 nema17-nema17 might catch an eye
07:30 PM zhanx: https://www.thingiverse.com/thing:33053
07:31 PM rue_mohr: no... I told ya to just switch to smaller rod
07:31 PM rue_mohr: geee
07:31 PM rue_mohr: I'm using 5mm on one machine and #8 on another, it cleaned it right up
07:32 PM rue_mohr: and soft couplers
07:32 PM zhanx: https://www.thingiverse.com/thing:9864
07:32 PM rue_mohr: their using brass bushings tho, so they know the linears suck
07:32 PM zhanx: i think that last one will make the prints worse
07:33 PM rue_mohr: also looks like a printed nut
07:33 PM rue_mohr: BINDING
07:33 PM rue_mohr: threaded rod is not straight and not centred
07:34 PM rue_mohr: you cant make it stop moving by holding both ends
07:34 PM zhanx: true and adding that lower mount to my z smooth rod helped a ton
07:34 PM rue_mohr: use smalller rod....
07:34 PM rue_mohr: dont use 5/16 or 8mm, use 5mm or #8-32
07:34 PM zhanx: then i have to buy it
07:35 PM rue_mohr: http://ruemohr.org/~ircjunk/projects/reprap4/p1100844.jpg
07:35 PM rue_mohr: see the small rod I'm using?
07:36 PM rue_mohr: I made nut adapters that you embed a small nut into in the middle of the print
07:36 PM zhanx: yep, last thing i need to print is a filament guide to keep it from rubbing and making noise
07:36 PM rue_mohr: no spool holder over the printer eh?
07:36 PM rue_mohr: http://ruemohr.org/~ircjunk/projects/reprap4/p1100859.jpg
07:37 PM rue_mohr: I changed that bottom one to a solid bar, and used another stacked clamp like on the joint to the frame
07:37 PM zhanx: i do but the filament still rubs
07:37 PM rue_mohr: sure, shouldn't be an issue
07:38 PM zhanx: so i am gonna make a little thing to press on the threaded rods to quite it down
07:39 PM rue_mohr: ah
07:42 PM zhanx: or electrical tape on them
