Hi all, new guy on the block. Can't seen to work out how to adjust the bed hight to nozzle distance on the 3D printer we just bought. Never done this before and I can't seem to find on the interface for the Vega300 interface dashboard on how to adjust this. when I print, the nozzle is so high (about 1.5mm off the bed), that the filament is airborn and not touching the bed as the nozzle darts around the board. Is it to do with the Printer itself, or is the setting feature in the progam? Just a bit stumped here. Any assistance is always appreciated Regards Paul
