For the Z axis motor pulley, Gt2 702mm. Should be a timing belt
*
Is this the belt no?

The model probably is 702 2GT (High torque timing belt) ? And you need to provide the width of the belt to buy.

Just go over to the shop and buy.

Call them up. Request to open account with them. Check the online catalog and order. Pay via online transaction. They will ship product to your place.

Misumi normally take 5-7days for delivery. It is slighty expensive than the local. Cause mostly is japan parts. But the quality is there.

Thanks for sharing. Do they sell  matching pulley/gear? Printed pulley can be unreliable sometimes.
*
Timing Pulley and belt need to be same model and teeth size. Cannot mix and match. If you use 2gt pulley, than need 2gt belt. Same as s3m, s2m etc.

i guess they do sell pulley. If not, you got to go to sri kembangan there. The gear shop name E-sungear and drive. Or you can look for this guys name jeffrey, stockgear n engineering at puchong. 0126955205.

What is the problem with the printed pulley? I thaught printed pulley last long. Cause not much torque running.

Sorry ozak. Mistake, I meant to say go to the shop you mentioned in puchong. iOS keeps on auto correcting

Sorry, I mistake you guys question. nnq is suggest misumi. Which is also a good source if can't get local. I myself brought a lot of misumi parts in working place. And very longtime liau.

GT2 is anti backlash.. cos pulley is going in forward and reverse direction all the time

powder base doesnt mean resolution is better.. wax printers got super resolution with inkjet piezo type ultra fine nozzles, and even resin printers..using Light DLP. smile.gif

We call it timing pulley. Mostly use for servo.

just follow what the GT2 makers call it lor.. why confuse even more.

Who is the GT2 maker?

I m not confuse you. GT2 is actually the timing pulley/belt model. Not the type of pulley/belt name. When we buy the pulley/belt, we have to tell timing pulley/belt or round pulley/belt. Than the model GT2 and teeth. Or GT2 lenght of the belt.

Timing pulley have model GT2, GT3, GT5, 8YU, S2m, S3m, S5m,S8m and S14m. All this different by the teeth size and mm size.

timing pulley and belt is a very general name, when you choose GT2 it means it's a very specific profile of teeth specifically for specilized application

so to say you just want to use timing belt/pulley it already not accurate there are so many types of timing pulley as you mention.
for example: see the image below, all still fall under  timing pulley/belt system but GT2 is only GT2 profile and shape, not the others which are also timing belts.

Thanks for your picture. Yes, it is a general name to discript what kind of pulley is that. Than you go to more specific model and detail.

I deal a lot with timing pulley and belt in working place. Mostly is s2m, s3m or htd. When I order, I will tell them the name than the model eg GT2. If those just working or fresh graduated, they will rclxub.gif if just tell them the model name.

Need some advise,

Is it possible for me to DIY a 3D printer here? I have some component like motor, driver, belt, pulley etc. No problem with the mechanical parts from finding 1 till design it.

The only part that I don't have is controller and the software. And know how to wire up to the controller.

Is it possible to DIY?

Electronic wise, if you are refer to adruino Electronic Gen 1~3, yes i think u can diy locally.

for software, there are quite many open source one.
Most importantly, you need to find one to supply you the printed parts and the vitamins
*
Thanks.

Is there any local website or somebody that I can hook up with to consult?

I m noob at the electronic side. For mechanical and eletrical side, not a problem.

What printed parts and the vitamins I need?

where to buy all these stuff?
*
In here, most of the stuff in 3D printer can be buy locally. Pulley, timing pulley, shaft, gear etc. Becuase this parts is more to industry, normal people will have a hard time to find. But if you ask those mechanical engineer, they know where can find those parts.

Only the controller and electronics you probably have to source out.

you are right smile.gif
but just some extra information.
i ever tried to source the belt,  shaft, gear, bolt etc, the average cost to build one locally is generally 20~40% more compare to import one kit directly. sweat.gif
*
Because of the high profit, quality and tax. I can buy this parts from japan and cheaper than here.

But nowaday, many taiwan, china and korea parts which is cheaper. It depend on quality.

Well, for me, i always eye for NON CHINA parts. Sad/bad experience made me stay away from China goods. (If you happen to use mechanical stuff/tools quite frequent you would know what i mean whistling.gif )
Unless budget is really a concern  only i'll pay the bill for Taiwan parts. If not, i general i normally get European made parts/tools.
*
Not sure how accurate the 3D printer need. If the accuracy is not that so important, china parts still can consider. But you have to know which maker is better. Taiwan should be ok. As long they takecare the quality. Cause majority the parts also from china. Just they have quality to control.

Europe parts is a bit expensive. I would rather get japan parts.

it's not about accuracy, it's about product life and quality  laugh.gif  i used quite some mechanical and electronic stuff from China about 10 years ago. You know what, about 5 years ago i totally quit using China made stuff already. Taiwan stuff still okay, but for me Taiwanese stuff are just too "Sudden". Japan or European stuff are fine for me. their price at the same level smile.gif

China part improve alot compare 10yrs ago.

But so far, I never use before. tongue.gif Mostly Japan or western parts.

Want to ask. Beside stepping motor, is there any controller/board using servomotor?
