Questions: 1. My bed looks like an ocean wave in the mesh. I tried to make it better by adjusting the screws but there isn't much accuracy there. The best I could get was +/- 0.325 which isn't amazing. Any good reason not to mod it to be able to fine tune bed corners? I was thinking swapping out plastic stand offs with springs. 2. The start gcode claims to have mesh bed leveling, but when I go to print it heats everything up and just starts printing. 3. I assume somewhere in the system files the nozzle heights are all specified and can be changed. I took a chance and let it print the first layer from T0 and it was amazingly dead on. I think I just got lucky. Amateur Tip of the Day: When ordering PTFE from E3D for your kit make sure you specify how long you want the PTFE... I just added to cart and got 100mm. Hence the capricorn tubing in my setup that Amazon shipped next day to me.
