I'm now getting consistent and acceptable (to me) results from my Axis, with about 30 good prints so far, mostly assorted parts for model railway rolling stock.
My first Benchy and the first try at a cooling fan shroud/duct both had some issues which I tracked down to too much slack in the X-belt. With that tightened by a couple of notches, things are printing much better.
The only other change (apart from the cooling fan duct) I've made to the stock Axis is to fit the 2nd fixed Z guide, supplied by Makertech with my replacement longer-lead heater/thermistor.
I made sure all the eccentric guides were finely adjusted to eliminate wobble and applied a smidge of dry lube to reduce friction. I also made sure the top bracket was bearing down properly on the top of the lead screw.
Maybe this is beginners luck (this is my first printer), but it does seem to have come together ok for me.
The only issues I've had with printing is a couple of times, it's just stopped mid-print with the hot end simply switching off. Not sure why?
