The Onefinity is a CNC router. It is used for precision-carving of wood, acrylic, soft metals and other materials. Onefinity generously discounted this unit through a Makerspace support program they offered to Hacksburg. A CNC router processes "G-code" to tell it where in X,Y,Z space to go, how fast, and in what order. The essence of the process is to first create a model or design (CAD, STL, Thingiverse, Inkscape), then convert that design into G-code. The G-code is transfered to the router controller on a thumb drive, and the router controller executes that code to completion.

Safety
You must be properly trained before using this machine. It uses a high speed cutting head that can cause serious injuries and a powerful motors that can damage metal, wood and especially humans! It also produces dust and that can be respiratory hazards, and cut chips that can be an eye or cut hazard. If at any time you feel something is wrong or unsafe, stop the machine. Your safety is more important than what you are working on.

Instructions CNC Router Tutorial (6/1/2025)
You can use other resources to generate g-code. Use LinuxCNC or other simple gcode
- Max F400 in/min for rapid 10,000 mm/min
- Max cut around 100 in/min 2500 mm/min
- Spindle speed 24000 rpm!
- Use gcode M3 for spindle on. Delay for spindle acceleration with
- S24000 M3
- G4 P8 ‘ dwell for 8 sec
- At the endo of your file, Use gcode
- M5 ‘to turn off spindle
Please have someone check your code first until you're very comfortable with this machine!
Note that this file uses metric for X,Y,Z and feedrates (mm/min)
Code Example
- G17 G21 G40 G49 G94
- G0 X0.000 Y0.000 Z6.000
- S24000 M3 'set speed and turn on spindle
- G4 P8 'allow 8 seconds to spin up
- G94
- G1 Z1.000 F1200 'move to height at 1200 mm/min
- G1 Y37.271 Z-2.261 F1284 'plunge into work
- G1 Y0.000 Z-5.522
- [lots of other G1 commands, or skip "G1" and just give X, Y, Z coordinates since G1 is assumed]
- G1 Y64.295
- G1 X65.965
- G0 Z6.000 'return to clearance height
- M5 'turn off spindle
- M30 'end of the program
Machine Tool Power Up
- Air compressor on
- Air valve (red) on
- Controller on. - black box silver button
- Home? Clear the edges! Ok
- Jog with Xbox controller
- Green=slow, red= medium Yellow= fast.
- Ok to shut ball valve while fixturing
- Carpet tape! Weight down workpiece
- Warm up procedure:
- Air back on
- Power for 220 VFD: behind crates
- Radiator: beige box on floor, top right rocker.
- Spindle will ramp up to 24k. Load & run Warmup.ngc on screen scroll list
- Clear the spindle, then hit play. Caution: it’s quiet! 8 minutes, then it stops
- check on Henry’s touch screen
- Check motor housing for shake, heat. Should be cool to touch, else the bearings are first suspect
- Wiggle check workpiece.
- Remove dust shoe to layout workpiece zero
- X0 Y0
- Set the tool in collet
- Hold tool, press pedal until completely out, release pedal
- Leave pedal tough to accidentally hit
- Hold tool collet just under, press pedal tough air clean a few seconds, push tool up and release pedal to catch spindle. Test spin with fingers and pull by hand to ensure seating.
- X zero: Machine is actually in metric mode for input values, but displays “inches”. Or “in”. It wakes up in metric mode. So input a 1/4” as 6.35.
- Replace dust shoe- magnet catch. Adjust dust feet with wing nuts for brush to contact work surface.
- Load your guide by inserting thumb drive in back of controller
- Press black folder and find thumb drive, folder and file. Then find file in drop down list
- Hook in dust hose
- Check everything!
- Turn on dust collection, gate open for your hose
Run the Gcode!
- Play button becomes the pause button. Hover your finger a while to be ready for any weirdness.
- Issue with job: screen pause
- Issue with machine: stop on back of controller
- See “remaining” indicator for job time. Progress bar is by line#
- Scroll display to x,y,x readout.
- Hearing protection
Shut down process
- At job end, use dust collector to clean area, then turn off.
- If you take out your tool, leave a tool in the spindle to keep it clean and spring catch engaged
- Home the tool to back left to leave table open
- Power off the air ball valve, then the air compressor
- Turn off the radiator
- Turn off the 220 Volt VFD
- Turn off controller
- Clean up everything
