When I go to print from SD the Z height is displayed as 1.9mm. Thats way too high. I have to babystep Z axis counter-clockwise 11 times to .8mm each time when it starts to print to get a good 1st layer. Is this correct because the gmax guide for the BLTouch says the Z-axis should be 1.9mm.
When I follow the steps in the BLTouch guide it says select AUTO-HOME, adjust the z-axis height in .1mm steps so that a business card just slips under the extruder nozzle and then adjust the BLTouch screws by that amount BUT no matter where I set the BLTouch screws, when I power up the printer it always goes back to 1.9mm and I manually have to adjust the baby step Z control with 11 counter clockwise clicks to .8mm.
What am I missing or does the BLTouch just not work on the gMax?
