RetroGlide V3 (Printed Parts only)

Retro-Glide V3

Full gantry upgrade.

So far, I'm able to have my max accelerations at 50k and my outer walls at 20k, with clean prints, you results may vary depending on your setup. My goal isn't speed; it's print quality, but the speed is a nice bonus.

This Gantry is based on V2.1 with additional upgrades. 

V2.1 was designed to use all the original parts and pulleys of the OEM gantry. 

V3 will require additional Parts as its base on getting the best Parts for the job.  

What's the Point?

The point of this gantry is to correct the skew and stiffness of the motion system, giving it the love it should have gotten from the factory. I have tried to make it as close as possible to the original gantry so you can use most of the original parts.

I have also moved the tensioners to the front, allowing for a better position on the back pulleys for better grip on the belts, allowing for better accelerations, and making it way easier to tension the belts with alot more upgrades such as the following.

Importance of Clean Graphs?

The nice, clean graphs for input shapers allow you to push it further than the recommended accelerations, because you are starting from a clean base with no vibrations. The faster you go, the more it amplifies the vibrations. So if you start with low vibrations, by the time you max out the vibrations, it'll be way further than the recommended accelerations. So don't look at recommended, look at the vibrations. See the added YouTube video for proof and added input shaper graphs.

If you don't know how to remove the top of the printer and access the gantry, please YouTube it first. It's really easy, and there are many videos on YouTube already. So take your time and do it properly.
