Beta Bed Leveling - Thx Kevin

Postby LaserGnomes » Fri Feb 15, 2013 5:19 pm

Stopped by TAM today for some new filament and various parts... on the way out Kevin asks if we'd seen the new top feed spool holder system. They had some on theirs in house and of course I was hawking the place so of course I noticed those! Looking forward to ours ; )

He then adds... what about the new bed leveling solution?
WHA?!
Hold on he says...

Comes back with 8 custom threaded thumb screws.
10 minutes later we are leveling the bed one handed while recording this video.

HIGHLY recommended at first use.

New spool holder is great can't wait to get my hands on one. The new leveling solution is also great. R & D is doing a great job!

Nice! I need to get my hands on a set of these. Do new printers come with these pre-installed?

They gave those to us today. Not sure if they've had them a week TBH. So fair to say not going in the batch they are currently assembling.. but who knows?

In any case the replacement took like 10 minutes seriously.
Leveling after that was so fast it didn't matter.

3 prints later and the bottom ones have backed off enough to allow the post to rock around.

Consider adding a washer to the bottom that has teeth in it to lock it into the wood?
Double nut the bottom one?

If we figure out a solution to it we will post it.
*Going to double nut with the nylon for now*

did you try to gorilla grip them on as tight as you could and they still fell out?

@ Turnrock Actually no... for 2 reasons.

1. on the video you can see as I adjust it... the needle swaying -/+0.08mm... that was literally just me "torquing" the nut and that tension translating through the bed into warping of the platform enough to cause that sway on the dial.

2. I'm strong enough to break bolts in half (no joke) so I try not to "give it all I got" for fear that's too much.

We'll try some alternates today.
On deck
Nylon 2ndary lower nut to stop the lower thumb screw from backing out enough for it to matter.
or
A small amount of modeling clay over the end of the bolt to stop the thumbscrew from vibrating back off.
or
A locking washer that would bite into the wood and would over come the vibrations that way.

The correct engineering solution is a split/spring washer between the lower thumbnut and the platform.
:D

It might also need a regular flat washer to stop the spring biting into the wood. But the spring washer will absorb vibration and should prevent it coming loose.

SPLIT WASHER FTW!
Off to the hardware store.-Strike- Had some laying around.

**UPDATE**

Installed with no bed releveling needed.

Printing some stuff now will report back if anything happens.

LaerGnomes, could you post a bill of materials for the bed leveling system you showed off? Especially links to the gauge and the gauge holder object would be appreciated.

Edit: found one Tramming Gauge via Thingiverse (http://www.thingiverse.com/thing:43453)
Pittsburg 1" Travel Machinist's Dial Indicator, item 623, as sold by Harbor Freight http://www.harborfreight.com/1-inch-tra ... r-623.html


Edit: Found the Tramming Gauge bracket by turnrock: viewtopic.php?f=1&t=103&p=439&hilit=leveling#p439

Thanks!
