Topic: Setting up Z-Axis offset in Repetier after adding Geckotek

So today I applied Geckotek to my print bed.I went into the settings menu for bed surface and put in -.50 for the offset. The printer then dragged the hot hotend through the surface material so now I am assuming I hosed this up. Does anyone have a detailed procedure for setting up a 1.0a AIO to use any of the aftermarket build sheets? Looking especially for setting up the Z. Assume the bed is leveled. Just want to know what to change where and how much in which direction to get the z to start at the correct height.

Re: Setting up Z-Axis offset in Repetier after adding Geckotek

A minus value should move the bed closer to the nozzle. The endstops in a Da Vinci are at the min position, not max. So when all the Axis are home it would be 0,0,0 with exception to any offsets that are set. It should have been .5, not-.5 as you found out. You have to think in terms of the logic and the direction of the moves the controller is expecting. All moves are in relation to the head. But since the head can't actually move up or down on these models then the bed is moving. So UP should make the bed move down, and DOWN should make the bed move up. It's confusing but Gcode was originally written for CNC machines like routers and all move commands relate to the head since most platforms on CNC machines are stationary.

Ideally what you want to do is tighten the adjusters down so the bed is at it's lowest point. Then place the new material down and use the manual adjustment method that is stickied in the XYZ section. Unless you have an extreme offset then your nozzle should not touch the bed with the adjusters fully tightened.
