Good to know there a shop selling linear rails in KL for a reasonable price, provided if you want to spend that kind of money.

Nowadays you can get stuff delivered from ebay within 2 - 4 weeks even for economy shipping. Obviously there is still that randomness factor but my last batch of shipping all came within 2 weeks.

By the way, I have a 10 meter roll of GT2 timing belt.

Does the rail look heavy or else the stepper motor have to push lots of weight around, slowing the max printing speed.

I'm pretty sure someone would have thought of using it

there's probably 700-800 ringgit worth of salvageable parts there , 4 8mm rod, 2 100mm rods, electronics, 8 lm8uu, 5 stepper motors, heat plate, bearing.

Unless I can sell it at that price.

PMed you for your Prusa i3.

Also, the rails are considered better than the linear rods since, they are usually made with hardened steel (very hard to bend and never flexes). I worked with one reprap printer using these rails and they are way better than linear rods and bearings since you only need one rail each to support a build platform or extruder in the 2 horizontal axis. You can use 2 rails for the z-axis, placed on two ends of one side of the printer against the wall.

I've researched a little bit on the rails and it seems like people do use it , especially on the Kossel kit.
On aliexpress I can get 3 400mm rails and 3 "blocks" for about 60usd.

The price you quoted is it "rails" only or come with the block?
do you have the name of the shop.

Do you guys using fan to cool down during your printing? I'm using abs and always having problem for the edge especially smaller object.
Print a 2 in 1 fan duct, it's help but sometimes will have crack problem.

ABS is very difficult to print for first time users. PLA is an easy alternative but trade off between s the material property.

For ABS printing, never use an external cooling fan at all even during bridging. The cooling fan causes severe warping and causes uneven temperature around the print. This will lead to uneven heights and even cracks.

I find that printing ABS requires no air flow and steady environment temperature.

a rail and a block. They're more expensive here than online tho. The best benefit is their ability to resist torsion force. If u hold ur extruder and try to twist it, the rods and bearing will flex. I've used these rails on a cutting machine and they can resist huge torsion forces.

Yeah, ABS is extremely difficult to print properly. The only fan i turn on when printing ABS is the hotend fan to keep it from overheating. The fan that is pointed to the print is turned off. Heated bed temp has to be quite high, I have mine set at 110C and also u need to prevent the part from cooling down. Keep airflow to minimum and try to keep the environment temp as high as possible.

Guy i got a small gear from robot that few of it teeth Is gone

Possible to use 3d print to duplicate it?

A picture with a ruler will help a lot for us. I am assuming the gear is a nylon gear.

Anyone know where i can get aluminum profile 20x20 here in malaysia? i'm contact misumi malaysia but they only accept order from company.

I still need 10pcs more to complete my list for corexy

PM me the list, the length and quantity. I may try to buy for you.
No surcharges.

KAMCO ALUMINIUM SDN BHD

Lot No.338, Jalan Sungai Besi,
57100 Kuala Lumpur,
Malaysia

they accept walk ins. I've bought from them before

Journey to build second 3d printer start

Nice corexy build,
I'm planning to build one as well except using hiwin linear rails(clone)

Nice, share your build also hiwin is nice but i can't afford it right now but i will upgrade to hiwin in the future

Does anyone offer service for assembling a Prusa i3 kit plus calibration? I may be able to get my hands on one but I just don't have the time to put it together.

Check out @altan salepage here https://forum.lowyat.net/index.php?showtopic=3843739# i think he offer services for assembling and calibration for rm500 fee. If you from kuching then i can help

Does anyone know where to get PETG filament? From what I read,

It is stronger than both PLA and ABS.
Minimal shrinkage which means larger print parts can be used.
Extrusion temp around 240c and 70-75C bed/ non heated bead
means it's not as taxing as printing abs and closer to PLA.

Thinking of using this to print my printer parts once it's done as PLA doesn't last.

http://taulman3d.com/buy-direct.html - look at their Tech-G material. u have to scroll down abit

i dont think it'll be easy to find PETG locally.
