My bed wasn’t level out of the box, it’s about 0.3mm low on the left, probably doesn’t affect much but for my own piece of mind I wanted it somewhat level. I started by opening the bottom and removing the grub screws holding the belt gear to the shaft but even with both screws removed I couldn’t get it to budge, I’m guessing it has locktite on it or glue…
So I came up with a simple spacer to slot under the bed mounting bracket, 0.5mm was about perfect, allowed for some squish, went from this:
To this:
It’s red because its above the zero line but most importantly it’s all basically the same colour, range of 0.148 compared to 0.3 something previously.
If anyone would like to do the same the model is here:
