Forgive my broken English and grammars!
I have been using the Maslow for a few months now. The biggest challenge for me was the z axis and dust control.
My Z axis upgrade was inspired by @Onelonedork. I have purchased a 100mm stroke actuator from banggood. I had to do some machine milling to shorted the actuator to about 70mm, This is because it needs to fit into the enclosure I built for dust control.
This is the 3D printed bracket for collecting dust at the source.
It looks crappy with those epoxy and PVC pipe, but it works pretty good. I would say it collect about 95+% of the dust.
Another angle of the whole assembly
This enclosure looks over kill, but all the rest of the dust that escape from the source stays in there. I also have a chinese knockoffs dust deputy in between ( this chinese knockoff one works better then the officially one, I have both of them)
And of course. At the end, I have to print myself a gold star
