Z-Level Adjuster for RigidBot 3D Printer: Fine-Tune Your Z-Levels by Hand Are you tired of adjusting your RigidBot's Z-levels with limited precision? Look no further! This adjustable Z-level system allows you to fine-tune your printer's height using a trusty M6 bolt. Pair it with Peter Stoneham's stainless linear bearing mounts and secure it with M4 hex socket bolts, just like in the pictures. Several variants of this concept have been tried before, but I've found them to be unreliable. Smaller screws tend to vibrate out of position or push the level switch further down over time. Lining up the switch and screw can also be a challenge. Not anymore! My design features a flat bottom M6 screw that hits the level switch at a 90-degree angle, making it easy to align by sight alone. The switch won't risk being pushed further down since it's already in its lowest position. You can use any bolt you like, and I've tested several. Update: 2016-04-09 I added a knob that fits onto a hex bolt head, making it easier to turn and more intuitive to use. The illustration on the knob helps you know which way to turn. Printer Settings: * Printer: RigidBot * Rafts: No * Supports: No * Resolution: 0.15 * Infill: 50% * Notes: + You can print the mount without supports, but the knob requires them. + I recommend a layer height of at most 0.15mm. + Tap the main bolt hole with an M6 tap when you're done printing. This will give you some resistance to keep the bolt from moving due to vibrations. To install: 1. Print the mount and knob without supports. 2. Unscrew the rear gantry rod holder screws. 3. Place the endstop adjuster in front of it and screw it into place with two M4 hex socket bolts. 4. Mount the bearing mount screw through the slot on the rear. 5. Secure everything as shown in the pictures.
