    • This animation highlight the assembly / installation of the EZR Struder.

    • Your EZR Struder will come nearly fully assembled from SeeMeCNC.

  1. Locate the EZR Struder pack from your kit or order. If you are assembling a printer kit, you will also need to locate the bank of stepper motors packaged in bubble wrap. You will need (1) stepper motor for the EZR Struder assembly.

    • 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.

    • Keep the EZR Struder assembled

  3. The orientation of the EZR Struder with the stepper motor is different for different machines. The image with the red arrows shows the correct oriantaiton when installing the EZR Struder on the H2.

  5. Locate the Hobbed Drive Roller. Slide the hobbed drive roller onto the stepper motor shaft. Note the orientation of the hobbed drive roller shown in the second image. Press the red release lever and slide the hobbed drive roller down into the EZR Struder assembly until the midpoint of the hobbed portion is aligned with the split between the base and cover pieces (indicated by a green arrow)

    • Rotate the stepper motor shaft so the flat is in the orientation indicated by the blue arrow.

    • Align the hobbed drive roller so that the set screw will be set against the flat in the stepper motor shaft.

  6. Tighten the set screw fully.

  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

    • HAND-TIGHTEN ONLY. These are being placed here for safekeeping only.

    • If you are upgrading a printer and ready to install, you will now install the EZR Struder using the (2) 6-32 x 1" machine screws and Nylon lock-nuts to mount your EZR Struder into you extruder mount.

    • The black lanyard clips are installed once the bowden tube is installed in the EZR Struder. We send plenty of extra in case you ever lose one.

I’m looking for a Direct Drive mount to fit the EZR to my linear rails for my CR10’s and ender 3. Not seeing anything though ;/ do you guys have one you’d recommend? Thx

Did not work for my Ender 3, The filament I am using is a flexible filament from 3D Solutech 1.75mm Real White. It would work for about 100mm or so, then the extruder sounds like it is jammed. I should have gone with a direct drive unit. I love the design of this EZR Struder. No hassle loading the filament anymore.

how exactly do we get the spring in? i ordered 2 of the EZR Extruder and both came with a piece of paper that a pear to show that the spring is supposed to be inserted in the red plunger and then the clear cover piece is supposed to seat back over it the problem with this is theres no cut out for the spring on either which leads me to believe the spring is meant to be compressed between the housing cover and the inside of the red plunger however there is not nearly enough leway to allow this to be done without the housing top sitting crooked and when you go to set it right the spring pops out and then your back to square 1. Not a very good product design in terms of the plunger there had to be a easier way of setting up a spring ? Am i just trying to install it wrong?

Has anyone been able to remove the Capricorn tubing from the extruder? Mine seems like it’s in there pretty tight.

How safe is it to take apart to clean out?
