Genmitsu 3018 Pro Z Probe Holder

Genmitsu 3018 Pro Probe Holder

Note: This is just one of many easy enhancements I have posted for the Genmitsu 3018 Pro CNC Router. None of my enhancements require any modifications to the stock hardware. Just bolt them on and go. If you look under my postings you'll see others including the Cable Chain, X,Y & Z Limit Switches, Vacuum Adapter, Cushion Feet, Clamping Set, E-Stop Mount and more.

If you have a probe then this addition will facilitate a pocket to store it on the Right bottom side of your CNC macine. There are a couple of difference Z probes available off Amazon. I chose item ID B0B778HLTV because I like how they used a connection block for the wires. See the pictures included.

Once I got this I decided to modify it slightly. As it comes it is embedded in a plastic sleeve. The overall height with the sleeve is about 20mm. The problem is that the standard Z max travel distance on the 3018 is 40mm. The means if you have to put the Z at least 20mm over your object to measure then the maximum height of any object (+ scrapboard if applicable) is 20mm or about 0.8". So I unscrewed and cut the wire into the puck and then removed the aluminum plug from the plastic housing (You can tap it out from the top). I then drilled a hole into the side of the puck and connected the wire to a banana plug which I can plug into the hole. The result is my puck is now less than 13mm tall. I also reduced the overall length of the wire to the puck as it was way too long. However, I am including both a standard puck file and a modified puck file here that you can choose from.

To mount the cup you will need to print the "BoxClip" file and one of the two puck holder files. Then use two m3 x 8mm self-tapping screws to secure the clip to the back of the cup. Then just snap it into place.

The pieces were 3D printed using PETG filament with 15% infill and no supports. It probably doesn't matter what filament is used but I find that PLA tends to melt and malform sometimes with temperatures and ABS can be a little brittle when trying to snap the chain links together.

Also I design everything in OpenSCAD which is a free CAD program. I have included all of the source files I made which you can modify as you'd like.
