CNC Mill - ICP 4030 Induction Prompts

• Soft Metals - Aluminium, Brass work well
• Wax - Machining or Jewellery
• Plastics - Doesn’t work very well

Ferrous metals are not encouraged

• Wood
• Anything dusty

Nothing that can create an explosive atmosphere

• Power to the VFD is cut when the door is opened (except sometimes it doesn’t - always close the door and open it again to stop it)
• Hardware E-Stop cuts power to the VFD and stepper motors
• Software E-Stop - GPIO from button or internal LinuxCNC faults
• MDI (Manual Data Input) is disabled while door is open. Beware entered commands will run as soon as the door closes!

• Don’t touch the tool while it’s spinning
• Make sure hands are clear when jogging spindle
• Avoid touching chips or workpiece - they can be sharp
• Your workpiece may be very hot, wait for it to cool down before moving
• Wear eye protection - tools can shatter, avoid rubbing chips on fingers in eyes
• Always supervise the machine when in use. Never take your eyes off it when in motion.

Observe the machine, check it looks like it does on the wiki. Check nothing is obstructing the spindle or bed.

Turn on the main power. Wait for Raspberry Pi to boot, Login with details ….

Check that the cooling unit has started up and is reading a realistic temperature.

Click on “my_cnc” to start gmoccapy.

Disable the E-Stops hardware and software. Click software Power On. (Note screenshots on wiki)

Check the mill is clear of obstructions and click the home button. I

Demonstrate jogging axis with UI and pendant.

Discuss workholding, point to vice and other blocks in drawers. Note nothing is aligned with anything else. Do not assume vice has been aligned or is bolted down correctly.

Demonstrate clamping workpiece into vice.

Discuss using mechanical wobbler to indicate in the workpiece. Point out draw with tools including wobbler.

Emphasise: the wobbler does not like high RPM, take care particularly after the machine has already been used. The spindle speed will likely be set to the previous value, using the UI will hide the speed. Always use MDI to start spindle.

Demonstrate MDI interface with “M3 S300”

Demonstrate setting one axis. Allow the inductee to set another axis.

Remove wobbler
