Default configuration, using only Z-endstop switch as Z-endstop. We’ll occasionally send you account related emails. For example, if the probe offset is -3.5 and you had +0.5 left, add the latter to the Z probe. In Marlin 1.x, this was done with X, Y and Z_PROBE_OFFSET_FROM_EXTRUDER. The next step was to disable the software endstops und lower the nozzle to its final position (using the paper test). Here are the different ways to adjust the BLTouch Z-offset for your gMax printer. And now, back in the Move-Z menu, the new starting value should be the original offset + the absolute value of the offset, so in my case it's 12.8. Check the Z position on the printer screen, and subtract another 0.1 from this value to account for the thickness of the paper. on How to calibrate Z-Offset with a BLTouch bed leveling probe? In text, this boils down to the following to be entered into Pronterface or … Using the Creality BLTouch Kit bracket, mine is { -43, -9, 0 }. P is the value needed to trigger the BLTouch. Use this formula to determine your Z offset needed: Z offset = -2 + 0.6 Z offset = -1.4mm Control > Motion > Z offset and enter the value obtained above e.g. This value will be adjust later on, to match our setup. ( 5.2 => -5.2) Set with M851 Z-5.2 and #define Z_PROBE_OFFSET_FROM_EXTRUDER -5.2. Learn all you need to know about BLTouch sensors: what they are, how they work, a setup guide, and where to buy your first BLTouch. privacy statement. The guide is specifically focused on configuring bilinear leveling where the sensor will first home Z at the center of the bed and then probe 9 points along the bed in a 3×3 grid for each print. The easiest way to get the Z offset value is to: Home the Z axis. To do this, find your probe offset, and add whatever offset remains to your Z probe. I am using Marlin bufix-1.1.x and recently upgraded from a capacitive sensor to an original BLTouch from Antclabs. Important: It is important to have Z-offset at 0 before calibrating. Fixed issue where Z-offset tool may not reflect the actual z changes when adjusting real-time; Added "Re-Home Z" button in Z-offset tool so user can make changes and test real Z immediately.
