Hi guys, I'm new to Reprap and just starting off my first build. I work with systems that use stepper motors, 2mm pitch timing belts, and pulleys at my day job, so when I saw that for Prusa Mendel V2 people were recommending a more accurate than T5 timing belt I knew immediately that that was the right thing to do. I know from experience the kinds of gains in accuracy and precision you get from belt tightness and teeth size. Anyways, I saw that in the belt guides (such as [reprap.org]) the only suppliers really were sdp-si and Misumi. Unfortunately the former only has something like 36 teeth pulleys, and the latter doesn't have a very friendly website at all. I wanted to maximize torque, since stepper motor speed didn't seem to be a limiting factor - just backlash, etc. So I did a little searching and found this place: royalsupply.com I just purchased my timing belts and pulleys. I got them 6mm wide, and chose the 18 teeth pulley (as per the minimum in the guide, and as a general average in what I've read other people were getting). Here are their pages for GT2 belts and pulleys: Pulley: [www.royalsupply.com] Belt: [www.royalsupply.com] Just figured some people might find this useful. Their pulley selection is great, but if you want belts the closest to 1m in size they have is something like 1.164 meters (the one I linked) which should work fine. https://reprap.org/forum/read.php?4,127922,127922#msg-127922 Sat, 11 Apr 2026 05:16:30 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?4,127922,218727#msg-218727 https://reprap.org/forum/read.php?4,127922,218727#msg-218727 aduy Reprappers Sun, 16 Jun 2013 08:35:26 -0400 https://reprap.org/forum/read.php?4,127922,218385#msg-218385 https://reprap.org/forum/read.php?4,127922,218385#msg-218385 China Soure of GT2 pulley and belt

Yep, they are the same; we both get 'em from the same supplier. I like the ones that Lulzbot and I sell because their interior diameter is nearly identical to that of the 608 bearings we use for our idlers. As a result, the belt is straight, eliminating a source of positional inaccuracy (especially for the X-carriage).]]> Pointedstick Reprappers Fri, 11 May 2012 12:20:15 -0400 https://reprap.org/forum/read.php?4,127922,131828#msg-131828 https://reprap.org/forum/read.php?4,127922,131828#msg-131828 also, techpalidin , who is pointedstick on here has some that look the same to me.

as far as quality, i think it took out some of the waves in my prints that
was created by the big teeth going around the little 624 bearings on my orca x axis.
so flat sides are more flat.
they defiantly didn't hurt my print quality.]]> glrra19 Reprappers Tue, 08 May 2012 01:27:34 -0400 https://reprap.org/forum/read.php?4,127922,131538#msg-131538 https://reprap.org/forum/read.php?4,127922,131538#msg-131538 -------------------------------------------------------

Perhaps you should have looked a little further down the page? Drilling out these pulleys by hand is a recipe for an off-center pulley which leads to uneven prints.

i need a belt longer than1 meter they list them but no stock on any over a meter but good selection smaller.

also i think its a $30 min order]]> jm44807 Reprappers Sat, 28 Apr 2012 13:03:58 -0400 https://reprap.org/forum/read.php?4,127922,129658#msg-129658 https://reprap.org/forum/read.php?4,127922,129658#msg-129658
They gave me a UPS tracking number, though, which is nice. It went from ohio, to indiana, to illinois, to washington, and has arrived here in Richmond, BC yesterday. The last entry on the log says "Departure Scan" at 1:10 AM today, so presumably it will arrive here Monday since they don't deliver regular priority packages in Saturday. I'll let you guys know how they seem when I get them]]> pwn4 Reprappers Sat, 21 Apr 2012 14:14:58 -0400 https://reprap.org/forum/read.php?4,127922,129623#msg-129623 https://reprap.org/forum/read.php?4,127922,129623#msg-129623
Regarding the Misumi website, IMO it's like Google in terms of usability compared to that Royal Supply website. :) I can't find anything on there...

But if you tell me that you've actually received and used the parts that you linked to, I may try to place an order.]]> bosskong Reprappers Sat, 21 Apr 2012 04:33:57 -0400 https://reprap.org/forum/read.php?4,127922,129304#msg-129304 https://reprap.org/forum/read.php?4,127922,129304#msg-129304 crutonius Reprappers Wed, 18 Apr 2012 14:25:55 -0400 https://reprap.org/forum/read.php?4,127922,127922#msg-127922 https://reprap.org/forum/read.php?4,127922,127922#msg-127922
