Bed spacers to fix leveling

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:

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:

For the ignorant of us, why use a spacer under one side rather than taking the tension off the sync belt below the floor and turning the lead screw till its perfect, then tightening it up?

I published this before Sovol published their instructions for adjusting the belt, I initially tried loosening the grub screws holding the gear on the stepper but they must have used some serious thread lock as I felt like I was dangerously close to stripping the screw, didn’t think to release the belt to adjust it though. But either way, this is a simple alternative that allows you to fine tune without tipping the printer over multiple times to adjust it.
