Manual z-probe holder for Microcube

thingiverse

Human: *Note: This is a work in progress only for the firmware part: I had some problem having repetier firmware using this probe on Z-max connector, and does not have enough time yet to look at it. But it's ok, for the mechanical part (printing part, assembling and testing).*\r\n\r\nThis is a manual z-probe holder. "Manual" means you have to clip the probe yourself before launching an auto z leveling, and then remove it before printing.\r\n\r\nThis probe is not made to be used at the beginning of each print to make a z home. It's for launching a plate probe leveling for time to time, by measuring 9 to 15 points on the bed. As a bed plate is never 100% plane, each point may have a slightly z difference, the firmware will compute from them a mesh representation of the bed (with this hollows and bumps), and use it during the print to compensate by moving slightly the z axis (using the z motors).\r\n\r\nThere are two parts:\r\n- z-probe_fixer.stl is fixed securely on the x carriage, using the same screw used for the X endstop. You just have to use a bit longer M2.5 screw \r\n- z-probe_holder.stl is the moving part. It can be clipped on the probe_fixer before launching the auto mesh probe procedure, and removed after. A microswitch (the same as used for x/y/z endstops) has to be screwed on this part, and connected to the RAMPS (the z max endstop).\r\n\r\nFrom my first tests, the offset of the probe from the nozzle are:\r\n- x: -10\r\n- y: 10\r\n- z: 2.9\r\n\r\n
