Acorn + Clearpath CNC Control Box Bench Test and Overview

Today, we’re doing a bench test and deep dive into the Acorn and Clearpath servo control box for my new CNC build. We’ll look at the design and layout of the box, power supplies, and wire routing, and finally power it all up and do some bench testing. 00:00 Intro 01:19 Acorn and Ether1616 Controllers 03:03 Clearpath Interface 05:29 Layout and Wire Routing 15:49 Power Domains 20:10 Flyback Diodes and Snubbers 21:51 Control PC 24:53 Wireless MPG Pendant 26:07 Connecting Everything 27:19 Servo Brake 29:21 Bench Test: Motors and Brake 32:53 I/O Configuration 34:58 Bench Test: Pneumatics and Dust Collection 35:50 Bench Test: Servo Fault 37:02 Wrap I’m going to attempt to list all of the major components here, by source, but I’ll certainly miss something: *This site contains affiliate links for which I may be compensated Amazon: Wiegmann 20x20x8 NEMA1 Enclosure (eBay*): Noctua 120mm 5V Premium Quiet Fan (Amazon*): Noctua 40mm 5V Premium Quiet Fan (Amazon*): 120mm Fan Filters (Amazon*): Centroid Acorn Motion Controller (Amazon*): Centroid Wireless MPG Pendant (Amazon*): Mean Well 24V DIN-Rail Power Supply (Amazon*): Mean Well 24V 1A DIN-Rail Power Supply (Amazon*): Mean Well 5V 3A DIN-Rail Power Supply (Amazon*): 24VDC Coil DIN-Rail SPDT Relay (Amazon*): 1/4“ Pneumatic PTC Bulkhead Passthru (Amazon*): Ferrule Crimper Kit (Amazon*): SlimRun Ethernet Cable Right Angle 1ft (Amazon*): SlimRun Ethernet Cable 6in (Amazon*): SlimRun Ethernet Cable 2ft (Amazon*): Shielded RJ45 Bulkhead Passthru (Amazon*): Beelink i5-8279U/16G/500G Mini Computer (Amazon*): 14in Portable Touch Monitor (Amazon*): ServoElements: NEMA34 Servo Brake MBC034-24-012: Automation Direct: Weigmann 20x20x8 NEMA Enclosure: Wiegmann Perforated Subpanel: ESTOP Switch: Pneumatic Valve Manifold: Pneumatic Valve: Pneumatic Valve Blanking Plate: Wire Duct (1x1-1/2): Wire Duct (1x3): Illuminated Selector Switch: 10A Supplemental Protector: Contactor: Contactor Snubber: 1/4“ PTC Pneumatic Fitting: 1/4“ PTC Pneumatic Fitting 90deg: 1/4“ Pneumatic Tubing: DIN rail: DIN Terminal (Gray): DIN Terminal (Green): DIN Terminal Separator: DIN Terminal End Cap: DIN Terminal Jumpers (3X): DIN Terminal Jumpers (4X): Teknik: ClearPath NEMA34 Integrated Servo: IPC5 Power 72V Power Supply: Centroid: Acorn, Ether1616, MPG Pendant: CNC4PC: Clearpath Connector Board: Raw Kevin MacLeod () Licensed under Creative Commons: By Attribution 3.0 License
