Yes my prusa i3 came with this. so far i'm quite happy with it, isn't noisy for me.

If you like even less parts, don't use wade, just have the stepper motor directly attach to the hobbed gear and have an idler to hold down the filament. I have a box of assorted springs and I use them for making extruders.

Thanks for the compliments,    everyone here is contributing to the topic.

My 3D printer comes with its own hotend which uses a ceramic heat break and at first doesn't look like it can change to another hotend. I then designed my own adapter to fit with the J-Head end and thats when I am able to interchange it with other nozzles. I think your Wallace has several wade extruders with different hotend adapters available on thingiverse http://www.thingiverse.com/thing:18379/#files
The noise comes form the 40 mm fan, usually it is not noisy like running a pc but after long time when the bearing wears out, it gets noisy over a long time.
Yeah, trying to find the red that is similar with my 3D printer is near impossible...

The color for ABS and PLA differs a lot even if its the same in name, ABS seem to always be dull and matte but PLA seems bright and glossy all the time.

Does your J-Head have the same dimensions as mine?

from time to time I'm getting oval when printing with my mendelmax, it due to dust collected by the linear bearing on X axis quite annoying sometime when you realize it while printing, so I always check my printer movement before print and spray some WD40 to the bearing to make it smooth again, this where IGUS bushing come along still haven't ordered mine yet

I'm going to the aluminium shop again this weekend need some 200x200 alu plate for my print bed as I just realized that those inductive sensor can only detect metal to work

its cheaper to buy one than build one. not to mention firmware maturity should be seriously consider

put in layman term, the open source software share by builder are like 'Linux' OS. its basic, fully customizable(know/how knowledge very important) and functional. it might not be the best out there but it get the job done.
that being said, the 3D-printer manufacturer usually include their own developed OS, much like Window OS. it's fancy, friendly user and functional but less laggy (correct me if im wrong).

guys, my point here is not to undermine your interest nor this community. im technical guy myself and i like this kind of stuff. If in future i have time and money to spare i would definitely into this hobby.

cheers to you all.  

+1 but I'm not going to start long lasting windows vs linux debate here as it will be endless as I also made my living with linux  , 3d printer firmware (open source) has come a long way ever since it started it mature enough for me at least there are quite number of firmware available for 3d printer each of them have their own advantages

Hmm, just when you test it out, could you check if the filament would wonder sideways? As if the filaments were following the thread. I had an issue when my hobbed bolt was off it would start turning the filament, which caused it to shear.

Guys...which 3d printer should a beginner go with?

Found a company near puchong which sells bearings/pulleys/rods/lead screws/steppers. Fast email response, they even called me to find out what I needed. Their prices for the shaft is comparable to those that are being sold on aliexpress, coincidentally I found this company on alibaba

They quoted me
- RM5 for LM8UU if <10pcs, RM4.70 if >10
- 8mm shaft 380mm length RM16.70
- 8mm shaft 320mm length RM14.00

I'm gonna pay them a visit next week, they do walk ins which is what i like

Their website is http://www.letromec.com.my/ if anyone else is interested.

for I didnt order, all my funding going to flood relief my father house badly effect and still under water now, probably I try ordering from the next year once everything calm down

Just got back from the place. They dont have stock for the stepper motors and the smallest pitch for ballscrew is 2.5mm
for 0.5 or 1mm need to custom order and can take up to 3 months

I also saw a nut and bolt shop in this area. Didnt stop to see tho

one thing i learned from buying on aliexpress is there is no such thing as last day . prices go up and down to show that there are "discounts". just gotta wait for when they have those "discounts" which is like every few days. I bought 4 rolls one go with fedex shipping afew weeks ago, price goes down to about RM60 a roll.

This is the guy i bought from the last time, http://www.aliexpress.com/item/purple-colo...1213594189.html

price seems like ~1+ usd diff from the seller you posted.

Yeah i just noticed the wood and flexi stuff, good find , let us know the quality of the stuff once you've tried it.

Happy New Year. 

Lift free yes but clog and calibration always... 
See if they do knurling/hobbing for the extruder drive gear.
