My One Handed Bed Leveling Solution

Postby watsonstudios » Thu Feb 21, 2013 10:46 am

Here's a simple mod that allows you to level the bed with one hand, one tool. I just used threaded aluminum spacers (Ace Hardware) and switched to 10-32 hardware (Ace does not have metric threaded spacers). I still need to try better springs. These I had to cut but work fine for now.

You attach the spacers from the bottom using 1/4" 10-32 screws and lock washer. Tighten it to the wood. Then you use 3/4" 10-32 hex screws and the same washer/spring type setup as the machine uses.

With this setup, you just use your hex wrench or bit to tighten or loosen from the top. No more using both hands, messing with a wrench AND hex bit, lock washers and loose bed pillars. :D

With the screw underneath tight, you only have to turn the top.

Here's what it looks like. Same height off the wood as stock setup.

Nice.

Have you been able to do some testing to see if repeated removal of the bed causes the bolts to drift?

It would take up a bunch of space, but I would be tempted to put in some sort of locking device and a high load short travel spring between the spacer and the locking device. Otherwise I'd be concerned about the level drifting over time.

Although I do now have a really fun Idea that I need to go build!

I'll share as soon as its ready!

I see what you mean. I guess I will see after a few prints. I may add a set screw to each spacer. That should keep the screws from turning while removing the bed. "DING" Great idea! :D

I just built a minor variation.

There is ~2mm of X/Y play in the bed.

If the spacers were a very tight tolerance thread it might work. But right now its not as rigid as the double thumbnut design.

I think this will be a good solution and take up any slack in the spacer threads and keep everything still. I went up to 10-32 size screw and spacer. I used a cap screw so the top will still fit through the hole in the acrylic. You don't have to tighten the set screw very much to get total rigidity.
What do you think?

Ok, This works very well. I'm using 10-32 cap screws and had an ooops moment! The cap screws did not fit in the acrylic slots! The head went through just fine but the screw was too big - so I put the little dudes on the lathe and removed the threads on the upper half of the screw. This helped in 2 ways:
1. Made it so it would fit in the slots in the bed.
2. Allows the washer & spring to slide smoother without catching on the threads.

Once the set screws are tight, there is no movement in the bed leveling posts.

Problem solved, at least for me.

Nifty!

Sticking with the thumbnuts for now though ;)

We'll be rolling them out into production fairly soon. And we'll bag some up with the washers and things that people need as make those available to people too.

We 2nd this solution.

36 hours of printing.. no loss in level.. no slipping nuts (lock washer fixed it).

Im thinking the perfect solution would be a mixture of Watsonstudio's mod with thumbscrews. one handed no tools needed bed leveling! but then i have no idea how you could get around having to unscrew them all to get the bed on and off.
