12:03 AM rue_: thats bad
12:03 AM rue_: mmmmaybe not
12:03 AM rue_: I hate trying to deal with "did not ship it" and ebay
12:03 AM rue_: because they do not properly notify you that your purchase protection is run out
12:04 AM rue_: or running out
12:04 AM rue_: and then they just offload it to paypal to deal with
12:05 AM * ^kat^ nods
12:05 AM ^kat^: and never return an item for full refund to China, they will "never got it" , therefore you didn;t return it
12:06 AM rue_: huh
12:06 AM rue_: never tried

12:23 AM * rue_ thinks ....
12:24 AM zhanx: fender washers is what you are thinking of
12:24 AM rue_: no
12:24 AM rue_: usually the native size of washer is kinda big
12:24 AM zhanx: i need 8mm
12:24 AM rue_: no
12:24 AM zhanx: usa remember
12:24 AM rue_: 5/16 is completely close enough to 8mm
12:24 AM rue_: I find that the one-size-small washer is a good fit
12:25 AM zhanx: i can drill out 7mmm
12:25 AM zhanx: but milestone for me
12:25 AM rue_: dont bother with metric
12:25 AM zhanx: k

12:26 AM rue_: only 2 have to 100% match
12:26 AM zhanx: bad rue
12:26 AM rue_: the others just need to be nema17
12:27 AM rue_: I'm not going to try to feed you the 'I fixed everything they did wrong' design initially
12:27 AM zhanx: no that can come after my prints suck
12:27 AM rue_: motors: X Y E (extruder) and two Z
12:28 AM rue_: for the Z rods, we will try to go 10-24 instead of 8mm or 5/16
12:28 AM zhanx: i got 1/2 and 5/16
12:28 AM rue_: 5/16 is the frame
12:28 AM zhanx: k
12:28 AM rue_: you want like 2' of 10-24
12:29 AM zhanx: given me 3 more days and i get to build a frame
12:29 AM zhanx: yes it will suck
12:29 AM rue_: I think we still need to make a few more corners for it
12:29 AM zhanx: but it will be free
12:29 AM rue_: it'll be yours
12:29 AM zhanx: yes and i did not buy it!
12:29 AM rue_: and bootstrapped, thats a bragging point for sure
12:30 AM rue_: besides, its not like you need one yesterday

12:32 AM zhanx: free this time
12:33 AM zhanx: got 3 of them
12:36 AM zhanx: fyi the wife said i can just buy a 3d printer and i am not
12:36 AM zhanx: but the extruder is what gets me
12:56 AM rue_: yea, thats harder for sure
12:57 AM rue_: I think you can wood it
01:19 AM zhanx: k
01:19 AM rue_bed: I'm supposed to be your guide

09:46 PM rue_: 2 days 8 hours 8 minutes
09:46 PM katsmeow: on ebay, they just promice 35 day delivery, the ebay cutoff is 30 days for refunds
09:47 PM rue_: right, and they dont tell you where you are in your 30 days
09:47 PM rue_: iirc they make it 30 days from something arbitrary
09:47 PM rue_: and then they pull the item from your purchased items list
09:47 PM rue_: if it didn't dissapear bcause of a bug in their system
09:47 PM rue_: provided they even told the seller you bought it when paypal took your money
09:48 PM rue_: }:( not happy with ebay

10:55 PM * katsmeow would be happy as pink with a cnc pcb driller, and baby mill for cutting at steel, and a nice manual lathe or two
10:55 PM Tom_L: something like that would be awesome to own
10:56 PM rue_: kat, did I tell you the software I wrote?
10:56 PM rue_: 3 points in the file and in real space and it works out the offset, rotation, and sclae?
10:57 PM katsmeow: no
10:57 PM rue_: so you pick 3 pads, show it where they are on the real pcb, and it corrects all the other points in the file
10:58 PM katsmeow: nice way to get a purty trailer hitch while you eat lunch
10:59 PM Tom_L: a kid in my catia class was running a similar one
11:00 PM Tom_L: he wanted to learn how to program it fully
11:00 PM Tom_L: nobody at his place could
11:02 PM Tom_L: https://www.youtube.com/watch?v=LdCRCcwDeKQ

11:36 PM rue_: which isn't really worth it
11:36 PM Tom_L: ssd is
11:36 PM Tom_L: i should get a box to put it in some day
11:36 PM Tom_L: it's still in the box

11:40 PM rue_: cause I have two (technically 3) tohers
11:43 PM katsmeow: i cannot get over two things about yootoobe videos on making steel things: steel from the supplier is NOT dimensionally accurate, and making thing that "look about right" is seldom good nuff

11:44 PM katsmeow: i *know* those hinge pins are where they belong to +/- a few thou
