12:16 AM rue_bed: heh
12:20 AM zhanx: again
12:20 AM zhanx: rue_bed: the frame
12:27 AM zhanx: rue_bed: my x-axis is short
12:28 AM zhanx: so i am gonna level it smaller the first time
12:28 AM zhanx: i need 18 mm more for the rods i have
12:28 AM zhanx: i will make brackets for it
12:29 AM rue_bed: wait
12:29 AM rue_bed: whtasa the length of two of the nuts
12:29 AM rue_bed: remember you doubled those nuts on the top?
12:29 AM zhanx: not the same
12:29 AM rue_bed: check if you reduce it to 1
12:30 AM rue_bed: per side, it'll bring the X rails in
12:30 AM zhanx: the smooth rods for for x axis
12:30 AM rue_bed: yea
12:30 AM rue_bed: thats what I'm talking about
12:30 AM zhanx: i took them out
12:30 AM zhanx: still short
12:30 AM rue_bed: the length is determined by the distance of the z motors
12:31 AM rue_bed: right now you have two nuts between
12:31 AM zhanx: ok i removed them 2 hours ago
12:31 AM rue_bed: two nuts must almost be 18mm
12:31 AM zhanx: wrong place
12:31 AM rue_bed: thatbrought in the z motors right?
12:31 AM zhanx: z yes
12:32 AM rue_bed: when the z motors are closer the x rods are shorter
12:32 AM zhanx: wait i am saying this wrong
12:32 AM zhanx: the rods for the z are too short
12:32 AM rue_bed: OR I can show you how to make collars to hold the rods out further
12:32 AM zhanx: 18 mm
12:32 AM rue_bed: hu?
12:32 AM zhanx: i dont have x yet
12:32 AM rue_bed: but, didn't they already reach?
12:33 AM zhanx: due to you saying don't cut them
12:33 AM rue_bed: if their too short for z, their ok for x
12:33 AM zhanx: no
12:33 AM rue_bed: whaaaa
12:33 AM zhanx: also
12:33 AM rue_bed: the z rods are way longer than x
12:33 AM zhanx: y rods are equal to x
12:34 AM zhanx: not z
12:34 AM rue_bed: oooh, wait a sec, you mean you upsized the machine
12:34 AM zhanx: no i am downsizing
12:34 AM rue_bed: to just cut the rods in half
12:34 AM zhanx: rue i am getting 4 more printers tomorrow
12:34 AM rue_bed: I wish I didn't have to be up an 5am tommorow
12:35 AM zhanx: i know this is a issue i want to work out
12:35 AM rue_bed: try the bearings on 5/16 if it all goes wrong, you might just find their a awesome ffit
12:35 AM zhanx: fyi i am drilling out the x axis and using collars also
12:35 AM rue_bed: justone side
12:36 AM rue_bed: the other side can keep it
12:36 AM zhanx: k
12:36 AM zhanx: oh one more
12:36 AM zhanx: printer belts dont hold on gt2 pullys
12:36 AM zhanx: is that normal?
12:36 AM rue_bed: hu?
12:37 AM rue_bed: hold on?
12:37 AM zhanx: stay in place with out slipping
12:37 AM rue_bed: sideways?
12:37 AM zhanx: flat
12:37 AM rue_bed: hu?
12:37 AM rue_bed: oh the bearings?
12:37 AM zhanx: maybe belts i got suck?
12:38 AM rue_bed: around the bearings?
12:38 AM zhanx: rue_bed: i am testing now
12:38 AM zhanx: yes
12:38 AM rue_bed: yea, remember that spring guide I was showing you?
12:38 AM zhanx: should i just get some gt2 belt?
12:38 AM zhanx: i did that
12:39 AM zhanx: sill slipped 1/3 of the size of the pully
12:39 AM rue_bed: if your aligned close, and you have a 'suggestive belt guide' then it should stay
12:39 AM rue_bed: move the pulley over
12:39 AM rue_bed: alignment
12:39 AM zhanx: or i got cheap will fail stuff
12:39 AM rue_bed: I have lathe made pullies with walls in your box
12:40 AM zhanx: make it cheap for me
12:40 AM rue_bed: hah, its to 0.05mm
12:40 AM zhanx: nice
12:40 AM rue_bed: wont arrive for months tho
12:40 AM zhanx: hey rue_bed its almost done
12:41 AM zhanx: bed is cut
12:41 AM rue_bed: I have a horried day tommtoorw, need sleep, I need more ppics
12:41 AM zhanx: k
12:41 AM rue_bed: anda new kayboard
12:41 AM zhanx: i got fiber tomorrow
12:41 AM rue_bed: srry
12:41 AM rue_bed: ok
12:41 AM zhanx: i hate fiber
12:41 AM rue_bed: dont get any in your eye
12:41 AM rue_bed: remember the alc. wipes
12:42 AM zhanx: oh look scope stare at it
12:42 AM rue_bed: and the continuty tester
12:45 AM rue_bed: oh not polish type!?
12:45 AM rue_bed: :S
12:45 AM zhanx: friday you free?
12:45 AM zhanx: i need to align this machine
01:25 AM katsmeow: https://www.wired.com/story/a-robotics-startup-perishes-and-its-got-tales-to-tell/
04:17 PM Tom_L: kick up the heat and stuff some of these on a reprap: https://odriverobotics.com/#odrive
06:31 PM rue_mohr: why dont people understand you cant print fast
06:31 PM rue_mohr: its like cooking
06:32 PM rue_mohr: you cant turn up the heat 4x for 1/4 the time!
06:49 PM Tom_L: you don't cook that way?
06:49 PM Tom_L: i bet you could if the hot end were better
06:50 PM Tom_L: those might be better suited for a laser
07:04 PM rue_mohr: yea
08:26 PM Tom_L: what is cura compared to pronterface?
08:26 PM zhanx: i think so
08:27 PM Tom_L: 'i think so' wasn't what i was looking for :D
08:27 PM Tom_L: just wondered what it was
08:27 PM Tom_L: or how it compared to the other one
08:28 PM zhanx: well i use Repetier-host
08:28 PM zhanx: i need to install pronterface to check it out
08:28 PM Tom_L: iirc it was the 'goto' pretty much from the get go
08:29 PM Tom_L: freecad is getting better
08:29 PM zhanx: running the setup on it now
08:30 PM zhanx: need to install some python3 stuff brb
08:30 PM Tom_L: i had pronterface installed a long time ago and looked at it even though i don't have a printer
08:33 PM zhanx: well i see everyone talking about it on the videos i have watched, might as well look at it
09:16 PM zhanx: pronterface does not like my verision of linux
09:27 PM Tom_L: what are you running?
09:28 PM zhanx: ubuntu 16.04
09:28 PM zhanx: seems they need an upgrade package
09:30 PM Tom_L: i loaded debian 9 on one to try some software recently
09:30 PM Tom_L: haven't tried any reprap software on it
09:32 PM zhanx: k
10:29 PM zhanx: rue_mohr: well my hot end works, but its not installed and the board sees it
11:20 PM zhanx: rue knows I have questions
11:39 PM rue_mohr: shoot
11:39 PM * rue_mohr hides
11:40 PM zhanx: great
11:40 PM zhanx: while you are hiding walk me through your method of squaring the printer up
11:40 PM rue_mohr: ok
11:40 PM zhanx: also
11:40 PM zhanx: repieter is talking to my arduino with ramps now
11:41 PM zhanx: and the extruder works
11:41 PM rue_mohr: satep 1, level the Y rails by shimming the feet as needed
11:41 PM rue_mohr: use pronterface for now
11:42 PM zhanx: pronterface fails on the install for me due to a pythong gtk issue, not breaking my system to fix it
11:42 PM rue_mohr: !?!??!?!!
11:42 PM rue_mohr: ok
11:42 PM zhanx: ubuntu issue is all
11:43 PM zhanx: step 2? nudge
11:43 PM rue_mohr: * with the Y rails level in X and Y
11:44 PM rue_mohr: level the Z rails in X and Z (if that makes sense
11:44 PM zhanx: it does
11:44 PM rue_mohr: you will have to move the bottom middle bar back and forth
11:44 PM zhanx: just want your method so i can base line it against mine
11:44 PM zhanx: and fix mine
11:44 PM rue_mohr: ah
11:45 PM zhanx: i am "square" and level
11:45 PM zhanx: but
11:45 PM rue_mohr: then, level the X by adjusting the two motors
11:45 PM rue_mohr: then, level the BED
11:45 PM zhanx: ah that is my issue
11:45 PM zhanx: i did bed after y
11:46 PM rue_mohr: then you need to start doing distance calibrations
11:46 PM rue_mohr: the order shouldn't matter too much
11:46 PM zhanx: k
11:46 PM rue_mohr: after thats all done, there is distance calibration and squaring
11:46 PM zhanx: k
11:47 PM zhanx: walk me through that
11:47 PM rue_mohr: put a piece of... you ARE recording this, right?
11:47 PM zhanx: yep
11:47 PM zhanx: i log
11:47 PM zhanx: with my EYES
11:47 PM zhanx: and computer
11:47 PM rue_mohr: put a peice of tape on some filament in the extruder, but not bottomed out
11:48 PM rue_mohr: tell it to extrude 1mm of filament
11:48 PM rue_mohr: do rough recal
11:48 PM zhanx: ?
11:48 PM rue_mohr: new_steps = old_step * error
11:48 PM zhanx: oh
11:48 PM zhanx: ok
11:49 PM rue_mohr: if you send ? to the machine, it'll spill its settings (I think)
11:49 PM zhanx: i got the code
11:49 PM rue_mohr: M92 (iirc) is the steps/mm
11:49 PM zhanx: i can read that
11:49 PM rue_mohr: you (this is why you should use pronterface for now) set the slicer to send an M92 in the presetup to set the step distace
11:50 PM rue_mohr: then you can tweek it
11:50 PM zhanx: great
11:50 PM rue_mohr: this is hard when were not actually doing it
11:50 PM zhanx: ok then, beaglebone it is
11:50 PM rue_mohr: I cant help you with non-pronterface
11:50 PM zhanx: beaglebone can do the pronterface
11:51 PM rue_mohr: when the X, Y and Z steps are set up, you do a secondary leveling pass on the bed
11:51 PM zhanx: 3 point not 4 point
11:51 PM rue_mohr: take a business card, set any corner so zero height *just* touches the card
11:51 PM zhanx: also my plexiglass is 1/2 ish
11:51 PM rue_mohr: then move it over the corners (do it over the leveling screws)
11:52 PM zhanx: can i use a shim? i got a automotive shim set
11:52 PM rue_mohr: and tweek the bed screws so that its just touching card at all corners
11:52 PM zhanx: i can gap it
11:52 PM rue_mohr: the paper is nice cause you can feed it drag
11:52 PM zhanx: same with my set
11:52 PM rue_mohr: at that point, the bed is properly level
11:53 PM zhanx: i can do .005mm with my shim set
11:53 PM rue_mohr: no, cause there is a magic height
11:53 PM zhanx: k
11:53 PM zhanx: explain
11:53 PM rue_mohr: you just want it to be even, the distance isn't important
11:53 PM zhanx: magic height
11:53 PM rue_mohr: the printer does a funny thing with layer 1, you need to actaully adjust it based on how it prints
11:54 PM rue_mohr: once its set, you should be fine
11:54 PM zhanx: k
11:54 PM rue_mohr: UNLESS you motor couplers slip like mine did
11:54 PM zhanx: no i solved that today
11:54 PM zhanx: air line tubing
11:54 PM zhanx: and sets
11:54 PM rue_mohr: or the Z rod your Z home switch is on slips LIKE MIME DID
11:54 PM rue_mohr: sounds good, I'd like to see eh?
11:54 PM rue_mohr: anyhow
11:55 PM zhanx: will take pics tomorrow
11:55 PM rue_mohr: so, I have a test square to print, you dont take it off the bed, you print it and use a square to see if it came out ok
11:55 PM zhanx: k
11:55 PM rue_mohr: then adjust that bottom rod as req'd
11:55 PM rue_mohr: but if you leveled it up good, it'll prolly be ok
11:56 PM rue_mohr: the test square print will also tell you about adjusting your zero height
11:56 PM zhanx: tomorrow my game plan is hob the shaft
11:56 PM zhanx: set the bed
11:56 PM zhanx: wire steppers
11:56 PM rue_mohr: the extrusion should come out *just* a bit flattened
11:56 PM rue_mohr: not O not ___ but kinda (==)
11:57 PM zhanx: yep
11:57 PM zhanx: i was typing that
11:57 PM rue_mohr: :)
11:57 PM rue_mohr: and THEN you need to adjust the % tweek for filament volume
11:57 PM zhanx: ok we are on the same page
11:57 PM zhanx: wait on that
11:58 PM zhanx: that is printing not where i am at
11:58 PM rue_mohr: to do that, you make something with a solid top, the extrusions should come up to each other nicely, no excessive gap or overlap
11:58 PM zhanx: sadly i got my webcam working an reptier sending me stuff to my phone
11:59 PM rue_mohr: you can change later, I just need to be on familiar ground to set you up
11:59 PM zhanx: i can do the difference i think
