Y-Axis Bracket for Mini 3D Fabrikator Tiny Boy Final Highly Recommended

thingiverse

I had thoroughly examined several designs for the Y-Axis Stepper Motor Fan Mount component and determined that the optimal placement for this limited space part on the Mini Fabrikator TinyBoy would minimize interference. Never create something that obstructs or hits print movement while printing or during zeroing tests, particularly at full bed length! It becomes quite apparent on larger size prints nearing 80mm. The heat without bracket reached a temperature of 56 to 60deg Celsius for stock printers. If your stepper reaches 80deg Celsius, it indicates your Ramps Board POTs are not set correctly to the standard voltage settings of 0.60-0.62V and 1.12V on the other measured legs. Below these voltages, you'll experience pauses in extrusion for half a second at certain prints, resulting in multiple stains. The bracket effectively reduces temperature differences by up to 7 to 10deg Celsius, as tested. Prior to installing the strong 12cm fan, which brought X and Z axis temperatures down near 34deg Celsius, adding the tiny bracket successfully maintained my 30mm fan at a stable 49deg Celsius during operation. The printer has been printing continuously for weeks without issues, even running non-stop for nearly months. I chose ABS Black material as the base (which absorbs heat in my view) to combat the Y-Stepper generated heat, but you can opt for PLA if desired. Although ABS warps without a hotbed, I regard it negligible and acceptable given the tiny and compact design of this setup, making it an excellent functional solution. To prolong equipment lifespan, maintaining minimal operating temperatures is essential.

I hope you all enjoy using this design! **Print Settings** * Rafts: No * Supports: Yes * Resolution: 0.2mm * Infill: 25% * Notes: Use Cura's Further Settings to customize print settings * Print Speed: 40mm/s * Outer Perimeter Speed: 22mm/s * ETC (Estimated Time and Completion): 59mins 28s * Material: ABS Black ESUN 1.75mm Filament Length: 2769mm * Temperature: 230deg Celsius * Software: Repetier Host V1.5.6
