Can you adjust the bed on Taz 6?

Post by CottonFX » Mon Aug 27, 2018 11:08 am

This came up during another discussion I had but I'm wondering is it possible to adjust my bed to try to get it more level than it is now? I can tell that it isn't level looking at it and I know other printers have adjustment knobs.

It does auto leveling just fine and prints but I can see where it could potentially cause some problems with larger prints.

Mine is lower on the front left washer.

Also, do the z axis motors move independently of each other? I've noticed the left side of my X axis is lower than the right... I always thought it was part of the leveling process but maybe I'm wrong?

Look at David's reply in this thread for instructions on how to level the two z sides: viewtopic.php?t=5436

Once the bed is approximately level, the auto-level probing feature will take care of the rest. If the bed is visibly not level, something is not right with the y-axis assembly, take a look here for how it's constructed, perhaps you can figure it out. When I got my taz 6 (very used) it was also very loose and out of level, had to reprint some parts and rebuild it, works way better now: https://ohai.lulzbot.com/project/new-ta ... bly/taz-6/

!.) Check the Service Bulletins here:

See if you have one of the affected serial numbers

2.) Here's a link to the physical frame squaring check procedure:
https://ohai.lulzbot.com/project/squaring-taz-6-frame/

If you were to disconnect the load on the Z-axis by disconnecting couplers that ride on the Z-axis rods and were to turn one of the rods you would see the other rod move up or down in parallel with the one that you are turning, so yes they are synched together. Therefore if you're going to try and level the two disconnect the wiring harness from one of them and then adjust until they're level in respect to each other, if you don't I think it goes back to the same position, thus remains out of synch.

Personally I find the tape measure method difficult when you're dealing with millimeters trying to get them as close to the same as possible between each other. Lay a strip of wood or something strong and flat that you can get on the couplers and put a level on that strip, then adjust accordingly until the level reads level, then reconnect the wiring harness.

When I first got my Taz 6 mine got out of alignment somehow until eventually one of the couplers cracked. I returned it under warranty for repair and lost a lot of $$$ in the shipping cost. That's what they found, a cracked coupler. I learned! Hope this info helps you and others like it did me.

Good Luck!
