The difference between using this backlash suppression stuff I made and not using it is surprising. It isn't completely perfect, but now unless you know exactly what to look for the effects of backlash aren't noticeable.
Next we have to test cutting precision parts and make sure that they work too. Anything with 90 degree turns should work just fine.
And we may switch from a belt to a worm screw for the x axis which should greatly reduce the amount of backlash. #Engineering
