Palmer Engineering Lab 2 was in need of a large CNC Router forstudent and faculty use for larger part fabrication. The CNCrouter with a large working area was dismantled due toelectrical damaged. Nearly of the electrical components weredamaged, but all the mechanical components were still intact.Also, the previous design was primarily used to fabricate skis;therefore, it was grossly limited in z-axis movement, despite itslong z-travel screw.

Initially thought only one driver wasdamaged; however, the Proof of Conceptshowed that all drivers were damaged whenonly the replaced driver was replaced.

Challenging to complete PoC on time due toPalmer Engineering Lab renovation. Routerwas crammed into the 80F boiler room.

Increase Z-axis travel Replace and reinstall cooling system Store electronics in control box

Add circuitry protection to components

Ease of use User friendly software/set-up USB Connectivity T-Tracks and Clamps

Control box layout and mounting Push-pull fan configuration for cooling

Temporary coolant reservoir during installation Radiator mounted on side for liquid cooling

T-slots installed by carving slots in table top with working router Length of cut finished manually due to table limitations

Initial router test to ensure

everything was wired correctly.

Burn hole from to high a spindle

speed.

Running router to determine good

cutting depth and speed.

Slower spindle speed stopped

burning.

With trial software: only 50 lines of g-code. Logo finished manually.

With full software: Fully carved logo

Finished Master Millers Logo cut into an Acrylic block. Overall quality is

good. Minimal tool vibration. Vibration due to too high a cut speed. Other drawings cut into acrylic as

well.

Completed router with working software and

nearly limitless fabrication

possibilities. T-slots installed along x-axis. Material secured using t-clamps and

slots.
