12:01 AM katsmeow: midnite <click> brains shut off
01:22 AM zhanx: rue_mohr: still up?
01:33 AM rue_mohr: yea, gas
01:33 AM rue_mohr: stomach dosn't like anything I feed it
01:33 AM zhanx: k
01:34 AM zhanx: I got a beaglebone black, its not being used
01:34 AM zhanx: going to install octprint on it
01:34 AM zhanx: to control the printer
01:34 AM rue_mohr: k, maybe after we get things working?
01:34 AM zhanx: yes of course
01:35 AM zhanx: but it will free up a computer
01:35 AM zhanx: and use one that was laying around
01:35 AM rue_mohr: designing a new Y bearing system...
01:35 AM zhanx: k
01:35 AM rue_mohr: yep
01:35 AM zhanx: umm
01:35 AM zhanx: 5d printing
01:35 AM rue_mohr: heh
01:35 AM zhanx: ka no support printing
01:36 AM rue_mohr: ya
01:36 AM rue_mohr: slicer problem tho, no cam software exists
01:36 AM zhanx: think after the printer is all setup and my 3d scanner is done, i will go more into it
01:36 AM rue_mohr: :)
01:36 AM zhanx: yes it does
01:36 AM zhanx: but its $$
01:39 AM zhanx: is fire control built in on the firmware in case of failure?
01:41 AM rue_bed: the new versions have a 'STOP EVERYTHING AND SHUT DOWN I CANT CONTROL THE EXTRUDER TEMP ANYMORE"
01:42 AM rue_bed: I find it a bit annoying, because I set the idle temp of the nozzel to 60c, and if I shut the power off it freaks out
01:42 AM rue_bed: BUT
01:42 AM rue_bed: one of MY connectors tried to burn up once
01:42 AM rue_bed: you know the 0.1" headers ?
01:42 AM rue_bed: well keep it to 0.5A or less per pin!
01:42 AM rue_bed: 1A is apparently too much
01:42 AM zhanx: k
01:43 AM rue_bed: the fires you hear about are almost all related to bed heaters
01:43 AM rue_bed: like 300w on 12V
01:43 AM rue_bed: @!#$!$?>????
01:43 AM zhanx: k, i was checking
01:44 AM rue_bed: but yea, I recommend watching the printer close for the first week
01:44 AM rue_bed: and not going too far away for 2 weeks after that
01:44 AM zhanx: i am getting a webcam for it
01:45 AM rue_bed: watch it close for a week, things can come loose that you dont expect
01:45 AM zhanx: and a monitor system separate for it
01:45 AM rue_bed: and insane adjustments
01:45 AM rue_bed: after that, its just general checks for a while to make sure its generally behaving
01:46 AM rue_bed: I do the same with the cnc machines
01:46 AM zhanx: true
01:46 AM rue_bed: I find that just about anything that is going to fail does it in the first 2 weeks or so
01:46 AM zhanx: k
01:46 AM rue_bed: after that, things seem to be good for years
01:47 AM zhanx: with the webcam you will be able to see it in action also
01:47 AM rue_bed: time lapse is nice
01:47 AM rue_bed: I suspect that warping happens in the first 3 layers
01:47 AM zhanx: that is what i have read and seen
01:47 AM rue_bed: I dont know if time is a factor, if I lapsed a bad print, I think I'd know
01:48 AM rue_bed: there are some things that are just evil to print
09:41 PM zhanx: rue_mohr: how long do you think one of these will last? https://www.aliexpress.com/item/dikale-1-75mm-ABS-PLA-DIY-Smart-3D-Pen-3D-Printer-Pen-Drawing-Pen-Nice-Gift/32857958514.html

11:01 PM katsmeow: there's no date on the datasheet, but these predate 74 series parts
11:01 PM zhanx: ok now i know that is old
11:01 PM rue_shop4: Tom_L, not getting product, them not processing orders properly and telling me to have paypal deal with it, them removing listings before I'v recieved them, them not telling me exactly when my purchase protection ends, ...

11:03 PM rue_shop4: (but no)
11:04 PM Tom_L: seem a little higher on ali
11:04 PM rue_shop4: its ok zhanx , you would have to pay more than they cost to send them to me

11:04 PM zhanx: not as a test and join project
11:05 PM rue_shop4: bad sellers sell things cheap to try to get their rating back up
11:05 PM zhanx: Canada costs too much
11:05 PM rue_shop4: they are usually bad sellers cause they dont ship and dont answer emails
11:05 PM Tom_L: good for me if they're trying to improve their rating by selling cheap to me
11:05 PM rue_shop4: heh
11:06 PM Tom_L: i don't need any right now anyway

11:42 PM rue_mohr: in sequencing
11:42 PM rue_mohr: cause they had like 8 taps
11:42 PM katsmeow: 175 watts to slow a relay coil?
11:42 PM rue_mohr: slightly different coil volages to delay things a few ms while everyone kicked in

11:43 PM rue_mohr: prolly can
