Mostly Printed CamSlider

Having built a half-dozen MPCNCs or so, I borrowed from that experience to build a camera slider at the suggestion of my son-in-law... the result, MPCamSlider. I first tried using the entire Z-axis lead-screw assembly from MPCNC... it worked but turned out too slow and noisy for my liking. I converted it over to belt-drive, mixing/mashing up motor- and idler-mounts for the conversion and preserving the conduit spacing from MPCNC's Z-axis assembly. The C-XYZ and C-spacer parts from MPCNC were used then to make a trolley and a custom plate whipped up to add a platform and help tie the trolley roller assemblies together. The overall length of travel can of course be made to suit... I ended up with 32"-33" of linear travel on the prototype.

The trolley has a small turntable affixed to the top for a rotation axis. I was originally inspired by the Brainy-bits camera slider tutorials and slider mechanism (https://brainy-bits.com/tutorials/control-2-stepper-motors-using-the-arduino-serial-m
