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…….



1 bed

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

    1. Hi, I don’t have one. If you can measure up yours, I’ll happily knock up an adaptor for you in fusion360 for a small fee 🙂 have already done a few for the 500’s and have some happy customers


      1. Thanks for the offer, but i’ve just brought 340x340x4mm plate, will just xfer the holes and drill.
        What do you use for slicing?
        I’m using Cura for Wanhao Beta 2 (V1.1) and find it much better than Cura 3/4.1


  1. I’m using Cura 3.4.1 still! – haven’t really had time or inclination to bother setting up anything later 🙂 – the stock wanhao build plate is 325×325 on the D9-300, the 400 will be closer to 410×410 i’d imagine – which means your 340×340 will be a bit too small as the thumbscrew parts are almost in the corners!


      1. Wow! Seems it’s the same size as the D9-300 bed.
        Show some closeups of the stock carriages, are they the same size as the 300 also!?
        Could be the same hole spacings also.
