12:00 AM rue_shop3: k,
12:03 AM rue_shop3: tell ya what
12:03 AM rue_shop3: I'll give you a model for a washer
12:03 AM rue_shop3: because
12:03 AM zhanx: k
12:03 AM rue_shop3: its an ok, tuning print, and when your done, you have a bunch of plastic washers
12:03 AM rue_shop3: http://ruemohr.org/%7Eircjunk/objects/20x7x2.stl
12:03 AM rue_shop3: use it to test that first layer junk
12:03 AM rue_shop3: its also good for inspecting the "100 infill"
12:03 AM rue_shop3: which is your temp/nozzel_size/extrusion_mult factors
12:03 AM zhanx: its printing
12:03 AM rue_shop3: hmm how do I disable a diode....
12:03 AM rue_shop3: A: use a 3 lead diode
12:03 AM zhanx: i have a color other than black for filament coming tomorrow
12:03 AM zhanx: so pictures will be easier
12:05 AM zhanx: well that bugger up
12:05 AM zhanx: need to lower the limit
12:05 AM rue_shop3: yes, but how
12:06 AM zhanx: didn't stick to the bed
12:06 AM rue_shop3: lower the zero switch a HAIR
12:06 AM rue_shop3: the other thing about the washer is that it dosn't use up much plastic
12:06 AM zhanx: true and not much tape
12:06 AM zhanx: hair too much
12:07 AM zhanx: split the difference
12:07 AM rue_shop3: with the 2:1 on my printer, it can push the head thru the tape
12:07 AM rue_shop3: happily
12:07 AM rue_shop3: ckckckckckckghgkckckgkgkc 8-S
12:07 AM rue_shop3: no skipped steps tho
12:08 AM zhanx: we need to fix my speeds
12:08 AM rue_shop3: 1 min
12:09 AM rue_shop3: M203 X83 Y83 Z2.5 E2
12:10 AM rue_shop3: ok
12:10 AM rue_shop3: ?
12:10 AM zhanx: ok
12:10 AM rue_shop3: put it in your book on the printer
12:10 AM rue_shop3: those numbers should be ok for any printer
12:10 AM zhanx: that washer is ugly
12:10 AM rue_shop3: do you know what the M201 numbers are? (acceleration)
12:11 AM rue_shop3: show me, it should come out fine
12:11 AM zhanx: what the heck?
12:11 AM zhanx: i did that command restarted and it extruded after the rim and then at the start of the washer
12:12 AM rue_shop3: it got confused
12:12 AM rue_shop3: reset
12:12 AM zhanx: k
12:13 AM rue_shop3: it doesn't really like numbers changing on the fly unless its at 0,0
12:13 AM zhanx: https://imgur.com/a/a1FZTDu
12:14 AM zhanx: the limit was a bit low on that
12:14 AM rue_shop3: oh, small prints, dial the speed down
12:14 AM zhanx: no its doing it again
12:14 AM rue_shop3: go to about 50%
12:14 AM rue_shop3: but it looks like your too hot still
12:14 AM rue_shop3: oh and zero is too low
12:15 AM rue_shop3: might be a lot of the problem
12:15 AM zhanx: zero is fixed
12:15 AM zhanx: default speeds?
12:15 AM zhanx: they are at 50 for some reason
12:15 AM rue_shop3: in pronterface, set the print speed to 50%
12:15 AM rue_shop3: or do you mean the M201, I didn't get answer on that one :)
12:19 AM zhanx: hold on took a picture for you
12:20 AM zhanx: https://imgur.com/a/Oz8uJ8d
12:21 AM rue_shop3: too hot, too low
12:21 AM zhanx: its extruding befor it prints
12:21 AM rue_shop3: no, its oozing cause its too hot
12:21 AM zhanx: no its extruding
12:22 AM zhanx: it stops and extrudes
12:22 AM rue_shop3: ....
12:23 AM rue_shop3: you didn't play with....
12:24 AM rue_shop3: aha, lets push in all sorts of numbers
12:24 AM rue_shop3: do you have the advanced tab in slic3r?
12:24 AM zhanx: in it
12:24 AM rue_shop3: ok, defautl extrusion width .41
12:24 AM zhanx: k
12:25 AM rue_shop3: first layer 130% (sorry I think I mixed you up with a different param earlier)
12:25 AM zhanx: anything else?
12:25 AM rue_shop3: 17% overlap
12:25 AM zhanx: changed
12:25 AM rue_shop3: bridge flow ratio 0.9
12:26 AM zhanx: ok changed everything else is 0
12:26 AM rue_shop3: under speed,
12:26 AM zhanx: k
12:26 AM rue_shop3: first layer speed, 30%
12:27 AM rue_shop3: skirt and brim
12:27 AM rue_shop3: min loops 1
12:27 AM rue_shop3: min. extrusion length 6mm
12:27 AM zhanx: k
12:27 AM rue_shop3: infill
12:28 AM rue_shop3: infill density 40% (this is a per-print adjustment quite often)
12:28 AM zhanx: pattern?
12:29 AM rue_shop3: I suggest rectlinear
12:29 AM rue_shop3: the hex is neat, but slow
12:29 AM rue_shop3: ok, under the printer settings tab
12:29 AM rue_shop3: retraction length 1.5
12:30 AM rue_shop3: min travel after retract 2mm
12:30 AM zhanx: following
12:30 AM rue_shop3: there is a setting I cant find about how much extra to extrude after a retract, I'm hoping you didn't put anything in for that
12:31 AM rue_shop3: oh, its there, extra length on restart : 0
12:31 AM zhanx: didn't touch it
12:31 AM rue_shop3: ok...
12:31 AM zhanx: found my issue tho while walking thro with you
12:31 AM rue_shop3: unless there is a signal mixup, you should be close
12:31 AM rue_shop3: ?
12:31 AM zhanx: retract only when crossing perimeters
12:32 AM zhanx: that was on
12:32 AM zhanx: causing the extra hairs
12:32 AM rue_shop3: ~
12:32 AM rue_shop3: try it
12:33 AM zhanx: ok starting the new print
12:33 AM zhanx: oh my temp is still 200
12:33 AM zhanx: but we can work that out as 185 sucks to print at and it don't get smooth until 200
12:33 AM rue_shop3: unfortunatly, the temp is at the mercy of the mental state of the sensor
12:33 AM zhanx: yep
12:34 AM rue_shop3: its pretty touchy, if I'm justing, its usually 2c at a time
12:34 AM zhanx: that was what i was doing
12:34 AM zhanx: the before extruding is gone now
12:35 AM zhanx: holy cow slow
12:35 AM zhanx: 22 minutes to print this
12:35 AM rue_shop3: small part
12:35 AM rue_shop3: 22?, well see how it turns out
12:35 AM rue_shop3: your watching the performance, not printing washers
12:35 AM rue_shop3: speed can be tweeked later
12:36 AM rue_shop3: well, I cant make this fcircuit reverse without adding another chip
12:36 AM zhanx: its dragging the head
12:36 AM rue_shop3: up
12:36 AM rue_shop3: and I find the blue tape sucks
12:37 AM rue_shop3: well, its a bit worse than the green
12:38 AM zhanx: what should i use?
12:38 AM zhanx: restarting after raising the zero
12:38 AM rue_shop3: I use the green tape
12:38 AM rue_shop3: yup
12:38 AM rue_shop3: dont worry about the tape
12:39 AM rue_shop3: that is a factor in larger prints
12:39 AM zhanx: still got a few hairs alreay
12:39 AM zhanx: temp is too high
12:39 AM rue_shop3: if its doing the gluegun thing, too hot
12:40 AM rue_shop3: but it wont completely go away till after your too cold
12:40 AM rue_shop3: increase the retract size and dial the temp down a bit
12:41 AM zhanx: down from 200 to 190 as a start
12:42 AM zhanx: still to high
12:43 AM zhanx: but half what it was
12:44 AM rue_shop3: hows the height?
12:44 AM zhanx: good i think
12:44 AM zhanx: sending a pic
12:44 AM zhanx: top is first at 200, second is at 190
12:44 AM rue_shop3: ok
12:45 AM zhanx: waiting on the upload
12:46 AM zhanx: https://imgur.com/a/m7LosJb
12:49 AM zhanx: i think we need to speed it up
12:54 AM rue_shop3: higher
12:54 AM rue_shop3: ( )
12:54 AM rue_shop3: your at __ still
12:54 AM zhanx: that first layer is so slow its gumming it up
12:54 AM rue_shop3: shoudnt
12:54 AM rue_shop3: its definitly too low
12:55 AM zhanx: raised it a bit more
12:55 AM rue_shop3: you need a ref image...
12:55 AM rue_shop3: I'm sorry I had like 3 hours sleep last night and a lot day at work moving our office to a new building
12:56 AM rue_shop3: I'm trying to solve a direction issue with this step sequencer and its not happinng without another chip
12:56 AM rue_shop3: two xor gates
12:58 AM zhanx: extruder motor is hot now
12:58 AM rue_shop3: dial current down
12:58 AM rue_shop3: a bit
12:58 AM zhanx: i did
12:58 AM rue_shop3: k
12:59 AM zhanx: while that is cooling down i am going to reset the default rates in the firmware
12:59 AM rue_shop3: hahah I dont need the two diodes
01:09 AM zhanx: ok after restoring default speeds 6 minutes to print
01:10 AM zhanx: and no more glue gun effect
01:10 AM zhanx: well a tiny one
01:16 AM rue_shop3: so I'm still 3 chips for 2 motors
01:16 AM rue_shop3: hmm
01:17 AM zhanx: wondering why my start temp is 5c less than layer 2 temp
01:17 AM zhanx: either way this is looking good
01:17 AM rue_shop3: sometimes, it works better if the first layer temp is a bit higher
01:17 AM zhanx: how do i set that
01:18 AM rue_shop3: filament settings tab
01:18 AM zhanx: both are at 192
01:18 AM rue_shop3: first layer: 195 other layers: 195
01:18 AM rue_shop3: yea, no point in using my numbers, the sensors are different
01:24 AM zhanx: still dragging the head again
01:37 AM zhanx: and rue_shop3 left
02:01 AM rue_shop4: no, UP
02:01 AM rue_shop4: UP
02:01 AM rue_shop4: UP
02:01 AM rue_shop4: higher than you think
02:01 AM rue_shop4: UP!
02:01 AM zhanx: k
02:05 AM zhanx: we need to do this on video
02:05 AM rue_shop4: first layer you mean, right?
02:05 AM zhanx: i killed your layer height
02:05 AM rue_shop4: zhanx, pulls a tom
02:05 AM zhanx: well
02:05 AM zhanx: the head kept rubbing
02:05 AM zhanx: now its not
02:05 AM rue_shop4: zero switch has to move up till its ( )
02:05 AM rue_shop4: not __
02:05 AM zhanx: i did
02:05 AM rue_shop4: the tip of the first layer should be flattened just a bit
02:05 AM zhanx: wait i will take pictures
02:05 AM rue_shop4: use a microscope if you have to
02:05 AM rue_shop4: I have good eyes
02:05 AM rue_shop4: I know people SAY that they have good eyes
02:05 AM rue_shop4: but then they cant read codes of 0603 resistors
02:05 AM zhanx: i wear glasses
02:05 AM zhanx: the layer height was wrong
02:05 AM zhanx: still need to tweak it
02:08 AM zhanx: your top mine bottom speed way to fast https://imgur.com/a/E6tW9FN
02:08 AM rue_shop4: too hot, too fast
02:09 AM rue_shop4: and first layer was too high
02:09 AM rue_shop4: that first image, the bead is o
02:09 AM zhanx: i adjusted speed and i got it wrong
02:09 AM rue_shop4: llike O
02:09 AM rue_shop4: you want ( )
02:09 AM zhanx: so down a hair again?
02:10 AM rue_shop4: yea, see how the bead is full round?
02:10 AM zhanx: it is
02:10 AM rue_shop4: you dont wnat it squished into the tape
02:10 AM rue_shop4: you dont want it fully round
02:10 AM rue_shop4: you want the top flattened just a bit
02:10 AM rue_shop4: less than half the bead height
02:11 AM rue_shop4: of flattening
02:11 AM rue_shop4: so height to be ~60-80% of the bead dea
02:11 AM rue_shop4: dia
02:14 AM zhanx: ok doing more one print
02:18 AM zhanx: ok i give up
02:19 AM zhanx: i am printing worse now than before
02:41 AM rue_shop3: it can do that sometimes
02:41 AM rue_shop3: I need t see to help
02:42 AM zhanx: spent 9 hours on this
02:42 AM zhanx: right now i am like done
02:43 AM zhanx: weird thing is big parts are now printing right again
02:43 AM zhanx: i think my speed and temp are way off for small parts
02:51 AM zhanx: rue_shop3, i also thing the retraction is wrong it seems to extrude more
02:55 AM zhanx: i set it to a negative value to see what happens
03:41 AM rue_bed: ????
03:43 AM zhanx: its working
03:44 AM zhanx: dont ask me i dont understand it
01:48 PM rue_shop4: rue_bed, email re sprayers replacement
