08:41 rue_school hmm
08:42 iveevue ?
13:10 SidSoy Hey guy's anyone familiar with EV3?
13:46 deshipu no, but you can ask your question anyways
13:49 veverak ok
13:50 veverak I clogged my printer
13:50 veverak again
13:50 veverak or my extruder is just so shitty?
18:34 veverak hmm
18:34 veverak I need to push something with weight around 600g up slightly
18:34 veverak hold it in that position for quite a long time
18:34 veverak and than release it down
18:34 veverak what would you use?
18:34 veverak normal size 20x20x40 servos needs a lot of space and I was wondering if there are alternatives
18:37 SpeedEvil What sort of speed?
18:37 SpeedEvil and how often?
18:49 veverak well
18:49 veverak it's for 3d printing with dual nozzles
18:49 veverak because I want system that is able to pull up one nozzle
18:49 veverak which actually means the nozzle + extruder and it's motor
18:49 veverak so.. often and fast? :)
18:50 veverak well, not really fast I suppose, I can fine tune speed later, need working system at first I suppose
19:14 SpeedEvil veverak: http://www.dx.com/s/motor?PriceIntvl=1-5&PageIndex=2#sortBar may give ideas
19:14 SpeedEvil http://www.dx.com/p/jtron-mini-7mm-stepper-motor-small-division-rod-with-slider-sliver-5-pcs-269593#.VcVEdfFVGRs
19:14 SpeedEvil possibly a little light, but the right idea
19:14 veverak yeah
19:14 veverak well
19:14 veverak I realized one thing
19:14 veverak I have two 500g things
19:14 veverak that I need to move up and down
19:15 veverak hmm, wait
19:15 veverak nah, that's bullshit :(
19:15 verak thought about using one servo for levering two of
19:15 veverak but hat would not be perfect

19:17 veverak hmm
19:17 SpeedEvil A small motor, and a worm gear or rack and pinion may work quite well
19:17 SpeedEvil you drive it at an appropriate limited current into a stop
19:20 veverak hmm
19:20 veverak well, I will play with servo for a while
19:21 veverak because making motor + motor controller ... well, servo is the easy way
19:21 veverak SpeedEvil: thanks for input!
19:24 veverak well
19:50 veverak http://i.imgur.com/cB5o1xt.png
19:50 veverak well, it looks liek it could work
19:50 veverak :)
19:50 veverak servos (ligt blue) will push motors up/down
