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:===
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
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.
