Frequently Asked Questions
How To Install
Q: Why is Bowden Drive superior to Direct Drive?
A: It may seem counterintuitive, but Bowden systems allow the extruder motor to be mounted away from the hot end, reducing the amount of mass moving around. This allows the machine to move at higher speeds and increased accuracy.
Q: What makes Capricorn Bowden Tubes the best?
A: Our tubing features the highest quality pure PTFE, high performance additives, and the most accurate inner diameter, for better prints every time.
Just ask our fans on social media, or check out our Technical Specifications Page
for more details.
Q: Can I use the stock fittings with Capricorn tubing?
A: Yes, you can re-use the original fittings
that came with your printer, as long as they weren't damaged during removal. We recommend replacing them for best performance however.
Q: Which of your premium Bowden tubes is right for me?
A: That depends on your particular application. For help in choosing, please see our Product Selection
Q: Can I print X in my Y printer with your tubing?
A: This question has as much to do with safety as it does whether it physically "will work." Please read our Safety Page
for a more in-depth answer.
Q: Where can I buy Capricorn Bowden Tubes
A: You can purchase them in our shop
, or from one of our many fine Authorized Resellers
around the globe.
Q: How do I cut and install my new Bowden Tube
A: Check out our How To Page
for further instructions.
Q: I placed an order from Capricorn forever ago, but my package hasn't arrived yet.
A: Deliveries using our standard shipping options should take no more than 3 days within the USA, or 21 days internationally. If this time has been exceeded, please check the tracking information first. (You should have received an email with the tracking number when the item was shipped.)
If it says the package has already been delivered, check with your neighbors or other people in your building who may have signed for it. We find that almost every single time, the package eventually turns up.
If you believe the package was stolen, or something else out of the ordinary happens, we can ship you a replacement.
Q: I'm a bit puzzled by your offerings for 2.85 mm filament.
For your 1.75 mm filament you reduced the inner diameter to reduce filament backlash and therefore improve print quality. For 2.85 mm filament you increased the inner diameter. I'd expect with the larger volume per unit length of 2.85 mm filament that this would exacerbate changes in nozzle pressure and make the effects of filament backlash worse.
Will you be releasing a version with a smaller ID?
A:Thanks for asking. We ended up going with 3.2mm ID, which is what Ultimaker uses, after a number of trials of other sizes. This is actually much tighter than most 2.85 tubing which is 4.0mm ID. We found that with the additional stiffness of the thicker filament, reducing the diameter any further caused too much friction, and did not work reliably.
Q: How can I sell Capricorn products in my own retail shop or website?
A: We would love to do business with you! Please contact email@example.com
for wholesale pricing. Note that as of April 2019 we are currently not accepting any new Amazon sellers.
