Belt Tensioner , do you recommend ? Hi Guys I have a heated bed that's 400x400 running on two 20x20 Extrusions with wheels. My question is I see some people add a Belt tensioner. ( The cloths peg type tensioner ). Would you recommend it. The belt from the stepper motor to the bearing ( Nut Tension ) to tighten up the belt is pretty long. So wondering if you add the wire tensioner in the middle of the belt would be beneficial.

if you have a Prusa type printer. Then there are nice tensioners available.
I use the first one until now it works very good

Sorry, not nice, too complex and not easy to adjust.
Should be either at the idler pulley, motor, eventually integrated in the carriage where the belt is fixed, must be simple, keep the belt straight, be accessible and if possible adjustable with only one screw.
A few can be found in Thingiverse. Some kits have correct systems too.]]> MKSA General Sun, 10 Dec 2017 05:43:10 -0500 https://reprap.org/forum/read.php?1,799484,800166#msg-800166 Re: Belt Tensioner , do you recommend ? https://reprap.org/forum/read.php?1,799484,800166#msg-800166 I use the first one until now it works very good

In that later case, you need some good nozzle pliers if not steel fingers !
Anyway, you must be close to the mfg spec (about 12 N for GT2 6mm w). In that case, they somewhat work, looks like it doesn't introduce too much elasticity. I tried it on a prototype and didn't notice difference when I removed it and tensionned the proper way.
Of course, if too loose, don't expect good results.
Fact is, a proper system is not that complex to make and far easier when it comes to install and tension the belt.]]> MKSA General Sun, 10 Dec 2017 03:50:10 -0500 https://reprap.org/forum/read.php?1,799484,800103#msg-800103 Re: Belt Tensioner , do you recommend ? https://reprap.org/forum/read.php?1,799484,800103#msg-800103 Srek General Sat, 09 Dec 2017 15:04:05 -0500 https://reprap.org/forum/read.php?1,799484,800033#msg-800033 Re: Belt Tensioner , do you recommend ? https://reprap.org/forum/read.php?1,799484,800033#msg-800033 DjDemonD General Fri, 08 Dec 2017 19:59:28 -0500 https://reprap.org/forum/read.php?1,799484,799601#msg-799601 Re: Belt Tensioner , do you recommend ? https://reprap.org/forum/read.php?1,799484,799601#msg-799601 Origamib General Tue, 05 Dec 2017 17:55:15 -0500 https://reprap.org/forum/read.php?1,799484,799565#msg-799565 Re: Belt Tensioner , do you recommend ? https://reprap.org/forum/read.php?1,799484,799565#msg-799565 www.thingiverse.com]

Probably one of those clothes-peg springs would be just as good; I never thought of them at the time.]]> frankvdh General Tue, 05 Dec 2017 13:11:16 -0500 https://reprap.org/forum/read.php?1,799484,799515#msg-799515 Re: Belt Tensioner , do you recommend ? https://reprap.org/forum/read.php?1,799484,799515#msg-799515
Clothespin spring tensioners should be in the 3D printer error hall of shame, right along side 4 screw bed levelers and acrylic printer frames.]]> the_digital_dentist General Tue, 05 Dec 2017 07:33:34 -0500 https://reprap.org/forum/read.php?1,799484,799508#msg-799508 Re: Belt Tensioner , do you recommend ? https://reprap.org/forum/read.php?1,799484,799508#msg-799508
Only drawback I know: You have to lower jerk and acceleration, else it would stretch and compress with every move.]]> Dancer General Tue, 05 Dec 2017 07:09:17 -0500 https://reprap.org/forum/read.php?1,799484,799484#msg-799484 Belt Tensioner , do you recommend ? https://reprap.org/forum/read.php?1,799484,799484#msg-799484
