Day 2 of owning my bot I did this- I posted to the forums on google but it came up so I thought a picture might help.Each cupcake has "left overs" more than enough to do this mod. the screw is mounted to the platform upside down. The first nut is a jam nut to hold the screw head to the bottom of the platform - the second is height adjustment - the 3rd is the top lock nut. Works wonders for me. Remove to 2 center screws. adjust the 4 corners to levle with your nozzle then add the middle ones back in. Check them often the vibrate loose - this is true of all the fasteners on the bot. Good Luck!
