<p>Hi Andrew,</p>
<p><br>
</p>
<p>I know some people who used something called Spectra Line as a drive for their Cerberus delta type printer (1m tall). <a href="http://www.spectrafishing.com/" class="OWAAutoLink" id="LPlnk942338" previewremoved="true">http://www.spectrafishing.com/</a>
It's a fibre rather than monofilament. There are some special grooved bobbins available to fit stepper motors but I don't know where they came from. Maybe getting the required tension is still a problem for your application though.</p>

<div dir="auto">Thanks everyone. I'll start using them.
<div dir="auto"><br>
</div>
<div dir="auto">As I said, I have never had a problem with DX, it's just that they aren't stocking the esoteric items I'm looking for.</div>
<div dir="auto"><br>
</div>
<div dir="auto">At the moment I am looking for GT2 belt (as used in 3D printers) in white, because I am going to use it for automatic curtains, and black would look bad.</div>
<div dir="auto"><br>
</div>
<div dir="auto">DX has 10m in black (only) for $8, BG has it in white for $12. DX has no stock of the GT2 pulleys, BG has all the popular variants.</div>
<div dir="auto"><br>
</div>
<div dir="auto">I have also noticed a few guys on TradeMe are reselling a lot of the cool modules, parts, and tools that you see on the Chinese sites. I ordered some black GT2 belt and some pulleys for more testing. I'll get them in a couple of days, but
they're more expensive of course.</div>
<div dir="auto"><br>
</div>
<div dir="auto">I tried using builder's line. It doesn't stretch but I can't get the tension I want. I tried fishing line, but it does stretch, and I found it snarling up on the drive pulley.</div>

<div dir="auto">Thanks,</div>
