Re: Adding an Openbuilds Openrail x axis to a Lulzbot Taz 4/5

And then I thought about modifying the backplate in a way where it would be as 3D printed as possible. I got the idea from one of piercet's first implementations, where the plate had a shape like an "X". I also needed a more firm way of tightening the belt. So, I came up with this: Backplate#1.jpg B...

Re: Adding an Openbuilds Openrail x axis to a Lulzbot Taz 4/5

You probably ran the belt upside down from how you had it before. In my current setup the main section of belt passes under the belt backplate anchors. if you have it going over them, you may need to either reroute it or change the direction in firmware. Yeah...looks like I rerouted the belt. Ooops...

Re: Adding an Openbuilds Openrail Y axis to a Taz 3/4/5

Thanks for the all the pics and instructions mikronano! I was able to get through the X-axis build due to the sheer size of the thread and people putting out their builds. With this Y-axis build thread being much smaller, it was a little daunting. All of your posts will help a ton when I get mine b...

Re: Adding an Openbuilds Openrail Y axis to a Taz 3/4/5

Thanks. But most of all, thank you for the whole V-rail project/idea. It is one of the best upgrades anyone can do for the TAZ. The size of the printer is quite big and the more you use it and the more familiar you become with it, then the more "delicate" it looks with the guide rods. But most impor...

Re: Adding an Openbuilds Openrail Y axis to a Taz 3/4/5

Good idea about the adjustabiluty on the endplates! I don't know why, but the drill hole center marks you show on the plate look too far in. This picture shows the correct hole position. Are you taking the cam offset into account? My calculations don't change that picture much. At my first and seco...

Re: Adding an Openbuilds Openrail Y axis to a Taz 3/4/5

If all went well and the wheels are put in place, the result should look like this: Bed plate drilled.jpg This is a side view of the fixed wheels. It is probably a good idea to tighten them first. Fixed wheels set.jpg And then it's time for the eccentric wheels. A 10mm wrench is needed now. I found ...

Re: Adding an Openbuilds Openrail Y axis to a Taz 3/4/5

I finally finished with the Y-modification and everything went great. I made myself some modification to the endplate files and I'd appreciate your opinions. First of all, I thought about changing the holes for the long bolts to slots. The reasoning behind it, is that the part of both endplates that...

Re: Adding an Openbuilds Openrail Y axis to a Taz 3/4/5

No problem. However... I did manage to forget about the spacers...

So... for the Wheels I should have also included the following:

(2) offset spacers 6mm (for the two adjustable wheels)
(2) aluminum spacers 6mm (for the two fixed wheels)

Sorry about that.

Re: Adding an Openbuilds Openrail Y axis to a Taz 3/4/5

I would say that the use of the End Plates is critical, since they help a great deal with keeping the V-rails aligned, no matter what. The only downside on using them is that you need to tap their ends with a M5 Through-Hole Tap. Apart from the extra cost, shouldn't you have one at hand, is the extr...

Re: Adding an Openbuilds Openrail Y axis to a Taz 3/4/5

Great! Thanks for the updated files. I also noticed that you re-oriented the offset for the upper holes on the Motor Endplate ;) .

I'll work on the new parts this weekend. I've made some thoughts but before I share I'd like to test them first.
