feiming, mind sharing where you bought the smooth rods from?

Found this printable i3 frame on thingiverse, think i'm gonna give it a shot.

Theres a v2, looks like its thicker and will take longer, i counted the time for slic3r to do just the frame parts, its gonna take 5-6 days to print everything.

the frame is sliced into multiple parts and joined with screws and nuts, some people used epoxy as I've read.

Printing complete. Total hours to print is about 65 hours.

altan printed in PLA, planning to start a 2nd one from scratch. Plan to take this slow .

Every day print 1-2 parts, used almost the entire spool, i'm guessing 600-700g since the AUW is 800++g, the screws are quite heavy, there are 6 bolts holding the joins behind the item.

0.2 is abit overkill, i printed with 0.3 and wow 400 is alot...

could it be the quality of the filament?

I tried your settings on my printer, had some problems with the support material. This is what i am printing at. Doesn't add much more time to the total print time for smaller items.

feiming have you considered an MK8 type extruder like this one
http://www.aliexpress.com/item/12-24V-Fan-...1851542508.html ?

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

have you checked belt for slop/backlash? i had that problem initially but adding a tensioner fixed the problem.

If you have DIY skills and some patience, you can get a prusa i3 kit with 2 rolls of filament for about RM1.5k on aliexpress. Thats the route i chose and took about 5 nights to assemble and tune the printer.

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.

Me and a buddy are building our 2nd i3, think we are gonna need more than 1M, i might go check CMW out for rods since it sounds like its cheaper to get it there, i'll ask about the nema17 and report back.

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

i print on an MK2B heated bed (heated bed pcb + 3mm alu) and white painters tape ACE hardware brand, sticks so well sometimes the tape tears off when prying print off. Only beef i have is that after afew prints and pry's, the painters tape crumples abit and the bottom of the print has weird shapes on them.

I also tried printing straight onto bare alu bed, didn't have much luck tho.

I've tried the PVA trick but i guess my mixture wasn't thick enough cos prints were still not adhering to the print bed. the ACE brand painters tape is pretty good for me, get 5-6 prints before i replace torn parts, doesn't give me sticky problems unlike the normal masking tape.

I've tried kapton with PLA with not much luck. right now i've switch to ABS to experiment, using kapton + abs juice.
