Tiny CNC XY gear with fitting and pen arm
thingiverse
Improving the Tiny CNC starts with modifying a pen arm that clicks onto the Z-axis and upgrading to an XY gear featuring a built-in indentation for motor installation, thereby eliminating one component while replacing it. Produce a single pen arm and two revised XY gears. Collect all remaining components and guides from the original design. Note that XYGearNew.stl has been optimized for micro-servos like the 9g model used in TinyCNC, differing from Plotter XY Gear designed for larger servos. For best performance with motor four-armed piece provided screws tightly, yielding quality prints. On pen holder male connectors should fit precisely into holes of Z-axis. Adding a dab of superglue holds them firmly and forever secure; create two to install one at the top of the axis and the other on the bottom. To simplify data transmission using your file name directly in SendingSerial004 processing sketch can be employed.
