Now for the most important part of the X gantry- the rotary tool. I spent a large amount of time thinking of ways to mount the dremel tool which would allow it to be removed easily, while retaining a firm grip on the tool, and not allowing movement. In the end, i found that two simple screws and a zip tie combined with a mount plate at the bottom sufficed!
Notice the rubber bands stretched on the Z axis. After more problems with stalling on the Z axis motor, I discovered a simple solution- to counteract the weight. The rubber bands work well in the working distance of the dremel tool, easing the load on the captive nut, allowing for smooth rotation of the motor. Simple, but effective!
