02:55 AM flav0r: that person was speaking your language dude
09:07 AM rue_mohr: Acz = sqrt(L^2 - (X - Avx)^2 - (Y - Avy)^2)
09:08 AM rue_mohr: ^^ ofcourse, its a sphere equation...
09:08 AM rue_mohr: I feel stupid
09:09 AM deshipu: wouldn't shphere have an euclidean distance in there, meaning there is a + and not a - under the sqrt?
09:10 AM rue_mohr: r^2 = x^2 + y^2 + z^2;
09:14 AM deshipu: so what does that - do?
09:14 AM rue_mohr: does seem out doesn't it?
09:15 AM rue_mohr: its one of the 3 equations for a delta printer
09:15 AM deshipu: ugh, I tried that once
09:15 AM deshipu: I mean, to derieve them myself
09:16 AM deshipu: https://hackaday.io/project/20379-deltabot
09:16 AM rue_mohr: I tried yesterday, got a geometry proof wrong and it all went left
09:16 AM deshipu: got pretty good results, but ultimately wrong
09:16 AM rue_mohr: I didn't try for long tho
09:16 AM deshipu: because I didn't include one angle that should be there
09:17 AM rue_mohr: ah, yea, the delta printer is different, linear sliders
09:17 AM rue_mohr: so I'm just working towards a rotational one
09:17 AM deshipu: I should probably revisit it one day
09:18 AM rue_mohr: the difference is that in the printer d cant change
09:18 AM rue_mohr: the base location changes
09:19 AM rue_mohr: anyhow, I didn't have the energy to really attack it
09:19 AM rue_mohr: not after giving up on the current direction of the CAM program
09:54 AM veverak: deshipu: that deltabot looks qute
09:54 AM veverak: I still have stewart platform on my tobuild list
10:21 AM veverak: https://imgur.com/a/SclhKVY
10:21 AM veverak: well
10:21 AM veverak: it planned some path

06:53 PM rue_mohr: veverak, your now the player/stage expert then?!!
06:54 PM rue_mohr: did it plan the longest path?
06:55 PM rue_mohr: that would be clever, usually people go for the shortest one, nobody would ever expect the longest.
