<p><strong>12/28/2020 Update:</strong></p> <p>I added the file<em>RP_200411_Servo_Z_Dual_X.cfg</em>* that has my klipper configuration using the servo for the Z-axis for reference.</p> <p>Z-axis servo/Stepper motor Pen Plotter mount for V-Slot</p> <p>I needed a pen mount for the Rolling Plotter I am designing and <a href="https://www.thingiverse.com/thing:2349232">https://www.thingiverse.com/thing:2349232</a> was pretty much what I wanted except I needed it to mount to a 2020 V-slot. I redrew it in fusion 360 like it was &amp; then modified it to work for my design. I had some troubles getting the servo to work with Marlin firmware, so I made a couple of other mounts to use a nema17 pancake stepper &amp; a 28BYJ-48 stepper motor. I then found a way to use the servo with klipper firmware, but might use a stepper motor later. I found the models of the servo, sharpie, &amp; 28BYJ-48 stepper motor on grabcad, but didn't include them in the fusion 360 assembly file here.</p> <p>The build log of my printer can be found here: <a href="https://openbuilds.com/builds/a-rolling-plotter.9207/">https://openbuilds.com/builds/a-rolling-plotter.9207/</a></p> <p>Here is a video of my plotter in action.</p> <p>For any of the mounts print: <strong>Pen_V_Mount.stl</strong> <strong>V2020_Z_6_4mmShim_Plate.stl</strong> <strong>Base_Slide_Mount_Long.stl</strong> or<strong>Base_Slide_Mount_Short.stl</strong>. The Long version is 5mm longer for looser spring <strong>V2020_Z_6_4mmShim_Plate.stl</strong></p> <p>4 -<strong>M3_Spacer.stl</strong> if using M3x16mm screws to mount Pen mount to V-slot mount</p> <p>For the servo mount style you can mount the servo on which ever side is more convenient for you.</p> <p>Print: <strong>Z_Servo_SideMount_V2020.stl</strong></p> <p>Edit the<strong>Z_Servo_SideMount_V2020.f3d</strong> file if you need to change any of the design.</p> <p>For the 28BYJ-48 motor mount you can also mount on which ever side is more convenient for you.</p> <p>Print: <strong>Z_Mount_28BYJ-48_V2020.stl</strong> <strong>Horn_28BYJ-48.stl</strong></p> <p>Edit the<strong>Z_28BYJ-48_SideMount_V2020.f3d</strong> file if you need to change any of this design.</p> <p>For the Nema17 pancake stepper mount, I only made a mount on one side, but you can mirror the part if you want it on the other side.</p> <p>Print: <strong>Z_Nema17_Pancake_V2020.stl</strong> <strong>Horn_Nema17.stl</strong></p> <p>Edit the<strong>Z_Nema17_Pancake_V2020.f3d</strong> file if you need to change any of this design.</p> <p>Depending on how deep your motor sits back, you might have to use the 4mm thicker*<em>V2020_Z_10_4mmShim_Plate.stl</em> rather than the 6.4mm plate above. If you need more depth than that, you can edit the<strong>V2020_Z_6_4mmShim_Plate v3.f3d</strong> to the size you need.</p> <p>I printed all the files at .2mm layer height with eSun PLA+</p> <p>I printed the Base_Slide_Mount with 4 perimeters &amp; 30% infill</p> <p>All the other parts I printed at 4 perimeters &amp; 50% infill.</p> <p>I only used supports on the front of<strong>Pen_V_Mount.stl</strong> print.</p> <p>I mounted the Base_slide to the V-slot mount with 4 - M3x16mm screws &amp; locknuts with a plastic 2mm washer.</p> <p>2 - M3x10mm screws with locknuts to clamp down the M3 rods on the slider</p> <p>1 - M3x16mm screw &amp; nut to clamp pen in place, you might want a longer screw for smaller diameter pens.</p> <p>2 or 4 - M5x12mm screws with T-nuts to mount to V-slot. Since pen is light, I only used 2 screws</p> <p>2 - M5x16mm screws with T-nuts to mount V2020_Z_6_4mmShim_Plate to carriage.</p> <p>I cut a 2020x250mm V-slot in half for the vertical V-Slot &amp; using the openbuilds V-Slot Gantry Plate-20mm for carriage which is 65mmx65mm. The springs I took from pens from a dollar store. Those springs were rather long, so I cut one in half &amp; used half on each side. The M3 rods I took from an old DVD drive as mentioned in the build I remixed this from.</p> <p>I have only tested the servo mount, so let me know if you find a problem with the other 2 mounts. I sized the nema17 pancake mount around the pancake motor from zyltech.com. All pancake motors are not the same depth.</p> Category: Art Tools
