Railcore Vibration Damper Mount

thingiverse

These are parts that allow mounting your railcore X/Y motors with a vibration damper. This makes the printer significantly more quite. As a bonus the drive pulleys are placed in double shear, taking all side force off the motor shaft. I printed all the parts out of CF PETG only the Pulley Support require support material. PDF in the files lists the full BOM required to build 1, you will need to double this for X and Y. I know this works with the 713 halo, I assume it works with the aluminum motor mounts. Probably does not work with the printed motor mounts. Some notes on the purchased parts: -Motor Damper, Available pretty much everywhere. I used these: https://www.amazon.com/gp/product/B07GWN6V89/ref=ppx_yo_dt_b_asin_image_o00_s00?ie=UTF8&psc=1 -5mm coupler, again you can probably get these from anywhere, I used these. https://www.amazon.com/gp/product/B07XXB1WR2/ref=ppx_yo_dt_b_asin_image_o09_s00?ie=UTF8&psc=1 - GT2 Pulley, I am using the gates one that filastruder is selling -5mm Shaft, Had some issues with this. the first ones I ordered were horribly tapered. I ended up with these and they worked ok. Cut down to 65mm long https://www.amazon.com/gp/product/B076XW73Q7/ref=ppx_yo_dt_b_asin_image_o07_s00?ie=UTF8&psc=1 - 625ZZ bearings can be sourced anywhere. https://www.amazon.com/gp/product/B01LWMT95S/ref=ppx_yo_dt_b_asin_image_o08_s00?ie=UTF8&psc=1 You will also want a bag of these to dial in your pulley height https://www.amazon.com/gp/product/B0036R4R9Y/ref=ppx_yo_dt_b_asin_image_o09_s01?ie=UTF8&psc=1 As far as stepper motors go you should be fine with just about anything. I know it works with both the E3D and LDO motors that came with the kits. anything with a shaft in the 20-27mm long range should be fine.
