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

Finished my X and Y modifications and the results are fantastic.

The printing is smooth as silk.

I printed an LCD Bezel and the bottom layers were perfect. No squished spots as was a constant problem with the Rods and Bearings.

A definite worthwhile upgrade.

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

Got the Bed on. My Eccentrics are at the extreme outside, so the wheels are as far away from the rails as they can get. What I've noticed that towards the end of the movement (front of machine) one of the stationary wheels slides against the rail instead of turning. For the rest of the movement, the...

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

I attempted to assemble my Y rails today and got as far as trying to mount the bed with the Wheels installed and there is no way the Bed is going on. I used the Drill Guides and the holes for the wheels are perfect since I used a Transfer Punch to mark the centers of the holes and a Drill Press to d...

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

For me it's not a big deal since I mounted an aluminum blade to my Miter Saw knowing that I was going to have to cut the X Rail.

But I can imagine it would be annoying for anyone expecting exactly 500mm.

I should measure all the ones I bought from Misumi and see if they are on spec.

I'm assembling my Y Rails now and also had to cut 5mm off each rail.

Re: Broken Nozzle

I recommend you buy a 7mm crowfoot and a torque wrench
What torque settings are we supposed to use?

Re: Extruder Clogged

I have a Buddha for each type of Filament. One for ABS, One for PLA, etc. The PLA Extruders have a fan attached that blows on the fins whenever the Hot End is on. Before I ever turned my TAZ 4 on, I read every post in these Forums and the general consensus was that you should never mix filament type...

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

Since those bolts are just there to set the belt tension, which is locked in place by the T nuts on the rail later, I just have the heads of the bolts straddling the plate. There is enough clearance to leave the bolts in place and still attach the plate, assuming the head is out of the way. With pr...

What voltage do the fans operate at?

What circuit are you hooking them up to?
