09:51 AM silopolis[m]: Hi folks
10:37 AM -!- #linuxcnc mode set to +v by ChanServ
11:20 AM unterhausen: the problem with 3d printing is by the time your part is printed, you have had time to realize you should have added something
11:21 AM roycroft: the problem with 3d printing is that it looks like crap
11:21 AM roycroft: it's ok for strictly functional parts
11:22 AM unterhausen: yeah, that's not really a problem
11:22 AM roycroft: but i don't want to ever see a 3d printer part on anything for which i have any aesthetic interest at all
11:22 AM unterhausen: but isn't that why maker spaces burn down, people soaking their parts in acetone to make them look better?
11:24 AM roycroft: cnc carving is similar, although generally not as offensive
11:24 AM roycroft: cnc carved parts may be somewhat pleasing aesthetically, but they have no soul
11:24 AM unterhausen: I'm currently making mounts for my dust collection system
11:24 AM roycroft: and that falls under the category of "strictly functional", at least for most folks
11:25 AM roycroft: don't get me wrong
11:25 AM roycroft: i have a 3d printer and i use it
11:25 AM roycroft: i've never made anything for sale with it
11:25 AM roycroft: for that matter, i've never made anything with it that lives outside my shop
11:26 AM unterhausen: metal 3d parts can be made to look pretty good, takes about the same amount of work as a casting
11:26 AM roycroft: and some resin printed parts look decent
11:26 AM unterhausen: I'm designing some lugs for bike frames. To have them cast would cost $25000
11:27 AM unterhausen: 3d printed, hopefully at least 100 times less. And they polish up great
11:27 AM roycroft: metal printed parts are generally more amenable to post processing than squirted plastic parts
11:27 AM roycroft: i don't care if it's 3d printed if it doesn't look like it's 3d printed
11:28 AM roycroft: aesthetics have nothing to do with process - they're about appearance
11:28 AM unterhausen: yeah, the local 3d printer guys asked for my help because their parts looked like crap
11:29 AM roycroft: and you responded "you are correct, sir!" :)
11:29 AM unterhausen: it looked good enough for me. I did figure out why, they were using marlin at high speeds
11:30 AM unterhausen: marlin code for corexy doesn't properly limit accelerations of the motors
11:30 AM unterhausen: just like lcnc, as it turns out
11:31 AM unterhausen: it was an amazing use of an arduino, I have to give them that much
11:34 AM unterhausen: I tried to buy the air duct mounts but they are expensive and none of them are what I want
01:53 PM roycroft: tgif, that's what i have to say
01:53 PM roycroft: and i'm taking five fridays off in a row again starting next week
01:54 PM roycroft: so this is my last tgif for a while - it will be tgit for a few weeks :)
04:13 PM jdh: the dropouts on one of my bikes are 3-d printed (Ti)
04:13 PM XXCoder: dammit
04:13 PM XXCoder: I want SLS
04:13 PM CloudEvil: Four billion dollars and change.
04:24 PM XXCoder: nah should cost around 30k
05:20 PM unterhausen: whichever 3d printing company that was in Massachusetts went under and sold all their machines
05:20 PM unterhausen: research machines were extremely large though
05:21 PM unterhausen: the local guys were there last time I went to their building
06:34 PM roycroft: i have never had to deal with dotster before, but they are dead to me
06:34 PM roycroft: my cat knows more about dns than dotster tech support
06:46 PM infornography: What is your cats hourly rate?
06:46 PM infornography: Does it work remote?
06:46 PM roycroft: probably less than what they pay the dotster monkeys
06:47 PM roycroft: she will purr remotely
06:54 PM XXCoder: roycroft: call in for purr service
06:54 PM XXCoder: $20 a hour
07:58 PM CaptHindsight[m]: all connections go through their patented litter-box technology
08:55 PM solarwind: CaptHindsight[m] were you the one with the relative who has a sunstone(?) pulse arc welder?
08:55 PM solarwind: The one that retracts the tungsten
08:55 PM solarwind: I remember someone here had one or knew of someone who had one
08:56 PM CaptHindsight[m]: nope sorry, none of my relatives are welders
10:06 PM unreal is now known as _unreal_
10:06 PM _unreal_: not much going on I see
11:02 PM _unreal_: So I guess nothing new is going on
11:03 PM _unreal_: I'm trying to decide how to rebuild the X/Z section of this bigger cnc machine quickly to make it rigid
11:03 PM _unreal_: hate to make it shorter but good god dam its flexy
11:25 PM * roycroft hangs _unreal_ a big chunk of granite
11:30 PM roycroft: i've already redesigned my gantry to increase rigidity, and i haven't even started to build the machine yet
11:37 PM _unreal_: At this point, I have a few choices of direction. and I'm thinking about cad drawing a new set of YX arms. So i can have them cnc water jet cut
11:37 PM _unreal_: I'm torn between 1/4" steel plate, and the .5" steel plate
11:37 PM _unreal_: the spindle on this machine is a 1.5kw
11:45 PM roycroft: i'm actually making my gantry side plates thinner, but adding a second set of linear rails
