ABL Sensor Mount for Type A Machines Series 1

thingiverse

After finally upgrading to the G2 extruder, I made it a priority to create a new mount for my capacitive sensor LJC18A3-H-Z/BX so I could continue using it without any issues. This universal ABL sensor mount should work perfectly for Series 1 owners (2014+). The sensor is capable of detecting the glass/PEI print bed currently installed in my printer, and I connected it to the Series 1's PCBs and ribbon cable to keep everything organized. The sensor I used can be found on Amazon at http://www.amazon.com/uxcell-1-10mm-Capacitance-Proximity-Sensor/dp/B00542U3M4. On December 12, 2019, I tested and started using "mount8.stl," which turned out to be a significant improvement over previous versions but still has room for improvement, especially when it comes to the snug fit of the hotend plug/clip and ribbon cable. On November 20, 2019, I removed "mount7.stl" due to fit issues and replaced it with "mount8.stl," which is essentially the same model but should fit correctly. On November 19, 2019, I added "mount7.stl," a quick and dirty redesign from scratch that should be more level, stronger, and easier to plug/unplug the hotend plug. This new design still needs some work on printability, but it should get the job done for now. As of now, it remains untested. On June 4, 2017, I added "mount5.stl" and "mount6.stl," both of which are angled slightly differently than "TAM_ABL_Mount.stl," to ensure the sensor is level with the platform. I believe mount6 should be the best option, but it's currently untested. I'm still using mount5 with a small plastic shim between the mounting hardware to angle it back a bit. Print Settings: * Supports: Yes * Resolution: 200 * Infill: 40% * Notes: + Print orientation: I printed mine standing up (flat surface down on print bed), with a small amount of support material to hold up the overhangs. + Sanding tip: I've found that sanding the inside of the ring helps with fitting the sensor properly. This may be adjusted in future models to make it unnecessary to sand. Basic Hardware Installation Notes: 1. Disconnect hotend from X-axis PCB 2. Remove two lower screws and nylon nuts from X-axis PCB 3. Slide mount up into place (over hotend terminal and around PCB) and fasten with two M3x6 screws 4. Re-connect hotend to X-axis PCB 5. Insert sensor wire through mounting hole from the bottom and carefully "unscrew" the sensor to the desired position (turning it counter-clockwise will pull the sensor up through the hole), and tighten down with provided nuts Wiring info can be found elsewhere for now, but should be pretty straightforward. DIY Marlin Firmware Modification: To make this work, I followed Thomas Sanladerer's instructions in one of his YouTube videos. For now, I'll link directly to the firmware section of the video I primarily used while learning how to set this up: https://youtu.be/EcGFLwj0pnA?t=4m35s (I recommend right-clicking on this link and opening it in a new tab or window).
