The number is how far away, in mm, you have the tool before probing, This allows the software to stop if it doesn't find the probe. In the Probe distance/direction box a positive number means your z axis has to move up to touch the plate, a more positive z value, and a negative number means the Z axis has to move down, a more negative Z value. You may have to adjust this value after testing, I had to increase by.

Put in your plates thickness in the Touch Plate Thickness box. Now measure your touch plate thickness in mm, you will need this for UGS. Retract Amount is how many mm the tool will move off plate after first touch and before second. You want this slow, so it gets an accurate touch. The Slow Measure Rate is how fast it retouches the plate to set you z. I successfully flashed GRBL 1.1 to my board using same method as above. I successfully flashed an EEPROM Clear command from Arduino IDE to my board, using arduino nano as a base. Fast Find Rate is mm per min for the rapid to touch plate, I set it at 100, it's not too fast, but I don't want to damage the plate. I now know my 3018 runs a camxtool v3.5 (some places they are referred to as a woodpecker control board, although there is no reference about it on my board). This is the same upgraded unit that now ships with most 1610-PRO, 1810-PRO, 3018-PRO, 3018-PROMAX (aluminum) desktop CNC routers. If, like me, you are only going to use the probe for Z you don't have to worry about End mill diameter. NOOB NEEDS HELP HAVE A CNC 3018 WITH A 'WOODPECKER CNC GRBL 0.9 BOARD) NEED TO UP RPM i have a cnc 3018 (chinese cheap model) it runs off grbl 0.9 the motherboard says 'woodpecker cnc grbl 0.9 when i increase rpm past 1000 in grbl the motors rpm does not increase above 1000. This three-axis control, GRBL based Woodpecker CNC V3.4 Control Board is compatible with many popular mini-desktop CNC routers and laser engravers. Units has to be millimeters, I could not get the probe to work with Inches. I'm un able to communicate with the board. Now originally this board worked well but unfortunately I believe i managed to short the board out and damage it. It included a pre programmed Woodpecker 3.2 board. So I've purchased a CNC model 3018 kit from ebay. The on-board ISP is unpopulated 1×6 connector right below the 2×17 header. First off im new to GRBL, lets make this known. Usual ISP connectors comes to 2,54 mm (0,1 or 100 mils) pitch. Second one, the ISP header IS present on the PCB, but is has 1,27mm (0,05 or 50 mils) pitch.
