Easy plug in 3-point bed leveling

[drayson 74]

Hi everybody...

what should I say... I love it when a plan comes together...

After a long time planning and struggling around with pro & cons I finalized my alu bed with 3-point bed leveling-project.

Here we go...

First I created repacements for the original bed leveling things and a new additional thing for the middle position in the back. The nice thing: no nuts any more as there are printed parts below the wood to secure it

Second, I organized a nice 5mm thick alu plate :smile:

Next, print all the necessary stuff and disassambled the original bed.

I drilled a 8mm hole in the middle of the back mounting positions and started assambling the whole thing...

And now - look at the pics... untested under printing conditions, but nevertheless looks awsome and works like a charm... Sorry, but I'm a bit proud... :smile:

Here are a few pictures:

 

The printable parts are available at http://www.thingiverse.com/thing:247552

Unfortunately there is just one issue left - my problem with wood glue printing at glass (there are some another posts helping me to fix this issue)

Next things:

 

• Add a nice silicone heating pad with a nice cable chain (gues there is one who might know... :cool: )
  
• Replace original wood arms with milled alu arms
  

 

... but that´s another story... :smile:

You have those wide arms on the wood arms at the front, but you attached your two front bed points to the springboard. Why not to the arms?

The arms are left from a previouse trial and honestly I was too excited of the new solution and forgot to disassamble them.

Unfortunately the setup I used them was not stiff enough so the plate itself was wobbling.

If used with a heated bed, the bed washers have to be replaced by metal ones.

If a cable chain is needed, you can use this one :-)

I changed my bed leveling also to three point, but I have one screw in the front and two on the sides.

I also installed a heated bed, but no Alu plate yet.

What are dimensions of the Alu plate? 220 x 220? Or a little bigger? What type of Alu is it the famous Mic-6? Mic-6 is hard to get in Europe, but after longer research and talking to specialized metal traders I found sth. which has the same quality and spec like Mic-6.

It´s called 5080 or 5083, you can buy it online here:

What type of silicone heating pad will you use? Do you have a source in Europe for it? All sources I found are in China or the US.

By the way, I like the printed cable chain you made for the heated bed. I think I will print one too.

I only used a Alu plate which we had in the company - honestly no idea, but it is nicely flat :smile:

The dimensions I used is the same as original (242x242) - there is a pdf at my thingiverse description also with all dimensions.

MIC6 plates you can get here, but as this is a TM, it is sold via ACP6000.

The silicone heating pad is shot on ebay - at a UK seller.

Unfortunately I had no time up to now to mount it - and there is still the relais and the PSU missing :smile:

Regarding cable chain, thank you - I placed it in the UM, you can find a picture I made yesterday in my other post.
