Plasma Operations Checklists

The following checklists can be used to ensure proper operation of your PRO CNC Plasma system.



1. Plasma CNC Power-On

Procedure Remarks
1 CNC Plug and Play Controller: Set main power switch to "ON" position CNC Controller Powered
2 CNC PC: Connected to CNC Controller (Ethernet)
3 CNC PC: Mach4 software loaded with plasma cutting tool enabled Use "Avid Machine Configuration" menu and "Machine Setup" tab.
4 Machine: Verify all E-Stop switches are unlocked Twist handle to unlock a locked E-Stop switch
5 CNC PC: Click the green Enable button to clear emergency stop condition If Emergency Stop condition persists, verify E-Stop switches and limit switches are not active
6 CNC PC: Check the TMC3in1 communications lights are Green TMC3in1 Status are found on the Mach4 "Diagnostics" tab
7 CNC PC: Verify machine moves using the jog keys (arrow keys) Be aware of machine position prior to jogging. Keyboard jog must be enabled.
8 Plasma Torch Power Supply: Verify compressed air line is connected and pressurized Reference your plasma torch manual for air pressure and flow rate requirements
9 Plasma Torch Handle: If equipped with a torch lock, verify this is set to "ready-to-fire" position Applies to Powermax 45XP machine torches. Note: Torch will need to be test fired once after switching from locked to ready-to-fire, to prime torch
10 Plasma Torch Power Supply: Set power switch to "ON" Machine is now ready



2. Plasma CAM Checklist

Procedure Remarks
1 SheetCam: Create new or Open your plasma ".job" file
2 SheetCam: Import vectors for this job as "new part" Verify your new part is selected
3 SheetCam: Select the correct tool from the tools list for your material type and thickness Avid CNC provides tool tablestool tables for your specific Hypertherm torch model
4 SheetCam: Create new "Plasma Cut" operation Operation > Plasma cut
5 SheetCam: Choose Contour Method Outside offset is typical for jobs with a mix of closed/open profiles
6 SheetCam: Select the layer that contains the vectors you want to cut
7 SheetCam: Configure lead-in and lead-out settings Edit individual start points which do not conform to global lead-in/lead-out requirements
8 SheetCam: Press OK and verify cutting preview shows a clockwise motion around your outer part profiles Enable Cut Reverse Direction if cutting preview needs to be reversed
9 SheetCam: Run the Post Processor and create your GCode file Ensure you use the AvidCNC Mach4 post processorAvidCNC Mach4 post processor

3. Normal Plasma Operations

Procedure Remarks
1 Machine: Load material onto water table and attach grounding clamp Ensure grounding clamp is directly attached to your material and has a solid connection with bare/exposed metal
2 Plasma Power Supply: Verify cutting amperage setting This will match the amperage of you tool from SheetCam
3 CNC PC: Verify THC (Torch Height Control) is enabled Torch Height Control toggle buttonTorch Height Control toggle button on Mach4 screen
4 CNC PC: Load program (G-Code) using "Load G Code" button
5 Torch Mount: Verify torch mount is fully engaged with magnetic alignment features in base plate
6 CNC PC: Zero X & Y on the front left corner of where you want your job to start
7 CNC PC: Zero Z with torch approximately 0.25" above work surface
8 CNC PC: Press Cycle Start button to begin cutting program Note: Wear appropriate eye protection. See your torch manual for proper shade level
