    • If you are upgrading your extruder on a machine you will need to remove the old extruder from the stepper motor.

  2. The main bodies of the EZR Struder have been zip tied together so they stay together during shipping. You will need to cut that zip tie and remove it.

  7. Install the stepper motor handwheel by aligning the flat of the molded handwheel with the flat of the stepper motor shaft and pressing down until it bottoms out. The stepper motor handwheel is used for manually advancing / retracting filament. If this is going to be installed in a new build install the (2) 6-32 x 1" machine screws and lock-nuts in the remaining  2 holes in the EZR Struder plates and hand tighten only

We meet again... Good job being careful to build right. I suspect many problems members come in to 3DPC 3D Printing Club are related to the build. Things affected by a poor or wrong build, one may never know. Quietness, operation, life of parts and print quality. I'm not even going to talk about poor electronics, scary. Reminds me to mention. No matter how high quality your rig is, please install a smoke detector close to your work area and keep everyone safe. Back to the build. High Five! ^5

Why are there no instructions on removing the "EzStruder" simply telling to do it is ludicrous. I bought the machine whole. I don't know all of the parts for everything...

...Couldn't you at least make a 5 minute YouTube video?

Jay Johnson - Reply

you are missing the beginning and the end to the instructions? you guys make like 4 different 3d printers and couldn't make a video upgrading each one? Im sure the product works great but the information on how to actually upgrade or use it is terrible

Is the EZR+Struder ok to fit Creality CR-10? Do you ship to UK?

Brian Weedon - Reply

Hey Brian,

you may want to check out Chuck Hellebuyck's Youtube. He just fitted this extruder on a Ender 3, wich is similar to the CR-10. https://www.youtube.com/watch?v=1GNDxvxp...

I’ve ordered one the other for day 14$ shipping via USPS to Switzerland. If you don’t find the USPS shipping option, get in touch with them by email and they will make that option available for you.
