3D Printing Forum

A friend was asking if I had any experience or tips to print with Ninja Flex on a newly upgraded Ultimaker 2 (+ now)

Any suggestions I can pass along?

I need to reverse the screw/nut on the slider block, fix the pulley on the Y axis then do your test. Been at the CNC machine the past few days so I haven't touched the printer

Details please!

This is cool!

Ok, will do that soon, have a busy night ahead.

Keep the existing firmware, yes? Or prefer non kickstart?

Well starting with a pulley that stops coming loose will be a good start for reliability.

Just found the UMO replacement fans are available on Fabrc8. 12v 1.2w. Almost tempted to buy a set and take some of the guess work our of my airflow

Okay....well this is he one for the Y motor...5mm is what I will order. Thanks for your help!

I couldn't find them on Fabrc8, that was my first stop

Neotko....metric drill bits...here?

Meduza/Neotko - What's the inner hole diameter for that pulley?

Don't have a lathe....and really don't want to deal with the mess of belts. Just want to replace that one annoying pulley If you spot a source, share please!

I've adjusted that belt as far it it will go (good and tight) Maybe I should replace that pulley since it only has one set screw. Would this one be a suitable replacement?

As I told Neotko....I should start accumulating the parts to give my printer a compete overhaul.
2+ Extruder upgrade kits are still back ordered everyplace i checked in the United States.
Then there's the electronics and determining what else I should replace (pulleys?)

Sure, we can sticky anything that you guys think is most helpful (Chip, let me know!)
