Calibration issue - see picture

Post by DITAmech01 »

Hello! I'm running a Max v2 with .91 firmware.

I've got the heights of everything adjusted so all looks great at the towers and at at the center. But there's an area where the hot end is, for lack of a better term, "pulling up" off the bed just enough to screw up larger prints. See the attached graphic. The red area is the problem area, and it gets worse the further you move from the center of the bed. When I print anything larger than about 4" across, it's hit and miss because the first layers in that quadrant don't always stick to the bed. Smaller prints are generally OK. My workaround so far has been to move large pieces off-center to avoid that quadrant, but I'd love to fix whatever variables there are to reduce the variance in that quadrant.

Any suggestions?

Red = "pulling up" area. First layers tend not to stick as well as hot end is too high.

Problem solved. Tyler at MatterHackers suggested that my X and Y endstops were set too high. Lowering them by turning the adjustment screws about a half turn CCW solved the problem and the MAX is back to work. Thanks Tyler!
