Dial Gauge Mounts for 3 Axis Calibration (X, Y, and Z)

prusaprinters

<p>These mounts allow step calibration for all 3 axes of your printer, providing a firm and secure mount for a dial gauge. These should work with any printer that uses 20mm V-slot or T-slot rail for the XZ axis mount, and any V-slot or T-slot rail for the Y axis mount.</p> <p>It is designed for a gauge with an approximate 57.7mm diameter body and 9.6mm diameter shaft sleeve, but it should work for slightly smaller gauge bodies. The top-end clip provides secure support for the gauge, but does not require an exact fit. I am using the Clockwise Tools DIGR-0105 gauge, as shown in the pictures.</p> <p>The mounting holes are designed for M3x10 or M3x8 screws and T-nuts to hold the mounts securely in place. I used one of the printable M3 T-nut designs available on the site.</p> <p>The XZ mount should simply clip to the crossbar with no screws, but holes are provided if necessary. The Y mount will require screws and T-nuts.</p> <h3>Print Settings</h3> <p><strong>Printer Brand:</strong></p> <p>Creality</p> <p class="detail-setting printer"><strong>Printer: </strong> <div><p>Ender 3</p></div> <p><strong>Rafts:</strong></p> <p>No</p> <p class="detail-setting supports"><strong>Supports: </strong> <div><p>Yes</p></div> <p><strong>Resolution:</strong></p> <p>.2</p> <p class="detail-setting infill"><strong>Infill: </strong> <div><p>20</p></div> <p><strong>Filament:</strong> IIIDMax PLA+ Space Gray</p> <p><br/> <p class="detail-setting notes"><strong>Notes: </strong></p> </p><div><p>I printed with 3 walls, no special settings otherwise.</p></div> Post-Printing ============= <p>The bottom supports for the XZ mount may leave the surface and rail clip edges a bit rough, but cleanup should be quick and simple with cutters and possibly some light filing.</p> <p>The XZ mount should clip securely to the X axis rail in both orientations, but if it doesn't then use screws and T-nuts to secure it.</p> <p>In an ideal world, your printer would be fully calibrated for a perfect fit, but then you wouldn't need these mounts. If the XZ axis clips are in the way, simply cut them off and use screws and T-nuts.</p> <h3>How I Designed This</h3> <p>While I liked the gauge end support from the original design, I was unable to find a good all-axis solution. Also, I felt that the X and Z axis could easily be handled by a single part, without resorting to using a gauge block.</p> <p>After a few test prints, I decided that the top of the gauge needed more support than the original design provided. I replaced the simple support with a more robust solution, so the gauge clips firmly into place and is held securely in any orientation.</p> <p>I originally wanted the Y axis to either clip on, or have a supporting ledge resting on the top of the bed rail. However this proved to be unreasonable when I took into account the narrow bed profile and the fact that leveling the bed may raise or lower it to a position the gauge couldn't measure. In the end, I decided that simple cutouts for the screws would be the best, most flexible solution.</p> </p></p></p> Category: 3D Printer Accessories
