02:23 rue_bed the story ends, well, I was able to reset it
02:24 rue_bed but the gears he printed missed the .5mm dia adjustment for being a hole and dont fit on the servos
05:20 rue_shop3 theBear, where the hell is rifraf?
06:03 rue_shop3 I wish the temporal dilation would be consistant
06:18 rue_shop3 almost 4, only another hour to go
06:19 rue_shop3 how long goes it take to go into sugar drop?
07:46 jrow Does anyone here use Moveit?
07:48 veverak hmm
07:48 veverak has anybody of you ever tried to cover 8mm smooth rods ?
07:49 verak found out that after year his bearings are unus
07:49 veverak which is partly because of the place I live in and many other things
07:49 veverak only thing that actually now make sense is to cover the reprap i3 so it won't posses problem anymoer
07:50 SpeedEvil veverak: 'cover' ?
07:50 SpeedEvil ah
07:50 SpeedEvil It's probably easier just to make an enclosure for the printer
07:50 SpeedEvil Even just a plastic tent
07:50 veverak won't help
07:50 veverak :)
07:51 SpeedEvil Why not?
07:51 veverak a lot of dust in the air
07:51 veverak and printer used only during the weekend
07:51 SpeedEvil Add a filter and a fan
07:51 veverak + additional pollution possible because I am not exactly
07:51 veverak "that kind of guy that got everything cleaner perfectly"
07:52 SpeedEvil Properly seal the tent, add a fan with a filter.
07:52 veverak and it would be silly to assume that that would chang anything soon
07:52 veverak SpeedEvil: and how to take care of the machine?
07:52 veverak upgrade partS?
07:52 veverak control stuff?
07:54 veverak http://www.tooms.dk/tblog/foto/cnc20131112chain5.jpg
07:54 veverak this stuff is normally used
07:55 veverak but let's say my printer is not friendly to this :/
07:55 veverak or was not designed in a way that they would suspest that somebody would need it
07:56 veverak SpeedEvil: btw: I have printer in box
07:56 veverak but 1/2 of that box can be taken away for better access
07:56 veverak still got this kind of problem
08:06 SpeedEvil Another option is your bearings are shit
08:06 SpeedEvil or lubrication poorly chosen
08:46 rue_bed whats wrong with dust?
08:51 SpeedEvil I'm assuming it's abrasive dust.
08:51 SpeedEvil Though for a heavily used year-old printer, I could see it being just wear
09:14 rue_house the way any of the repraps are built you cant expect more than 2 years without seeing wear
09:14 SpeedEvil Well, that does depend.
09:14 SpeedEvil Some of them have excellent wear properties.
09:14 SpeedEvil By being so shit they're used for three test prints and placed on the shelf.
09:16 rue_house you also have to understand mechanics to adjust them right
09:16 rue_house I dont think many people do
09:16 rue_house they just expect to assemble and use
09:18 SpeedEvil yeah
09:32 veverak rue_house: of course I can fail on this part
09:32 veverak :D
09:32 veverak rue_house: and it was heavily used in bad enviroment
09:32 veverak I can understand that they will wear during the time, but I suppose I can help it a lot
09:32 veverak SpeedEvil: choosed from local source taht got some "nice name"
09:33 veverak I mean, people that DIY CNC machines uses that shop a lot...
09:33 SpeedEvil If it's just 8mm rods - then replace
09:33 veverak "just replacE" will be the scenario when I will fail to find anything to make it better
09:33 veverak but I suppose I should be able to do at least something
09:34 veverak btw: new ones are allready ordered
09:35 SpeedEvil What are the symptoms?
09:46 veverak when I shake it it feels like balsl are missing
09:46 veverak and it's just to hard to move them on the rods compared to when I bought them
09:47 veverak much bigger resistance
09:47 veverak and sometime I feeel that it "blocks" for a while
09:50 SpeedEvil I would wash out the balls with solvent while moving and then re-lubricate
09:51 SpeedEvil this will almost certainly make it much, much better
09:52 veverak yeah
09:52 veverak well
09:52 veverak I said to myself that price is not high
09:52 veverak and I want to make it finally "proper printer"
09:52 veverak so... I want to still use new ones and cover them properly and take care of them properly
09:52 veverak while the old ones will be used for different purposes
11:22 deshipu hmm, I have some free space left on my laser-cutter order
11:22 deshipu I wonder what I should add there
11:25 SpeedEvil struts
11:37 deshipu strutzels?
