D9 – Some more upgrades – Belt Tension

I’ve designed another thing that solves some more problems with the D9 – a Belt tensioner!

Jerome Waweru D9-300 Y Axis Tensioner 9mm 1
Thanks to Jerome on Facebook for posting a pic of his Tensioner

I’ve posted this up on Thingiverse……….

It’s been printed at least 10 times by guys on the facebook group and provides an immediate and cheap improvement over the stock……..

Wanhao D9 – Poor Y axis design and free printable fix

D9 Motor mount 3

During my tinkering time with the printer, trying to improve the print quality I noted that something seemed a little ‘off’ with the Y axis movements……

Wanhao D9 Bed upgrade

The Wanhao Y axis ‘bed’ is known to be a little flimsy,

It’s made from pressed, welded steel sheet just under 1mm thick and notably flexes when adjusting the levelling springs

Some closeups below….

My new plan – Create a new Bed / Carriage with some suitably cut Aluminium from this bloke on ebay – 4mm thick and 325 x 325mm for just over £13, bargain!.

Once cut, this should be stiffer and more importantly, lighter than the existing carriage as shown below…….

When tightning, this black part can often bend, it’s only 1mm thick!

Exposed bed – it looks ‘deep’ from the front, but the ‘wings’ on the sides are flimsy and flex with levelling

It’s alive! – kind of. MGN12 Rails update

Well, the MGN12H linear rail carriages fit into the new carriage adaptors I quickly knocked up in Tinkercad perfectly!

And, don’t they look lovely in Purple (great filament from 3D Filaprint)

Now, to dismantle the printer and see if the print bed tray fits…………

That’s the problem with printing stuff to upgrade a printer, iterating takes time and stuff gets dismantled waaay too much! I need a second printer :-p

Still here! – Forthcoming upgrades

 

In my never ending quest to do everything to this printer, other than to print stuff, I’ve decided to perform a series of upgrades. It’s been a few months of indecision and procrastination, but…

 

Upgrade 1 – Linear Rails

Found these from a few forum posts recommending the manufacturer in CNC forums…

It’s a Hiwin copy , I’ve purchased the MGN12 – 500mm rails and the MGN12H bearing blocks…

I’ve received the rails and very impressed. Currently waiting another 3 x MGN12H in the post to make 6 total…and then I can get started
