GarageWorx CNC limit switch mounts

thingiverse

These thing files are the mounts I designed for limit switches on the GarageWorX CNC kit. I built them for my 4x4 model. I know the gantry layout is different on the smaller units, so the X-axis mounts may not work on the other sizes. The Y and Z mounts should though. You'll need one each of the Y-axis mounts, one each of the Z's, and then 2 of the X-axis mounts. They are identical from side to side. To mount the X's, take out two of the 1/2" 10-24 screws that mount the gantry cross and rail, replace them with a 3/4 or 1" screw and install them backwards so the threads face outward. Slide on the printed mount and then add one more 10-24 nut to secure the limit switch mount. For these switches, I used a set of smaller lever switches. Here is a link to them on Amazon: https://www.amazon.com/gp/product/B00MFRMFS6 For the Y and Z switches, I used the switches that I got from Xylotex. They are the common V-156-1C25 type. Here is a link to a set on Amazon: https://www.amazon.com/dp/B01G3FCH56 To mount the Y axis brackets, Slide the printed mount over the front and rear C-channel frames, line them up so the vertical gantry plate will strike the roller, and then add a glob of hot glue to each of the clip 'legs' to keep them from vibrating loose. The Upper Z axis mount is pretty straightforward. To mount the lower Z, remove the bottom two 1/2" 10-24 screws that secure the Z slider rail plate to the front of the Z-box. Replace them with 3/4 or 1" 10-24 screws just like on the X-axis mounts. Slide the printed mount in there - it's a close fit, so you have to angle it in there and then line it up with the screws. Then secure the printed mount onto the longer screws with one extra nut per side. All of the small screws that attach the switches to the printed mounts are 4-40 by 3/4" machine screws and nuts. I had to trim the middle screws on the two Z-axis mounts by about 1/8 of an inch so they wouldn't touch the lead screw. The others don't need to be trimmed, but can be to avoid snagging your hand when you're working around the machine. The lower Z and both Y mounts should be printed with supports. There is no need for supports on the upper Z or the X's.
