CALIBRATION

Calibration is an essential part of setup. Do not attempt to cut with ArcDroid™ until the calibration has been done successfully. Failure to calibrate properly will result in low accuracy cuts.

For a video tutorial on calibration, please visit our youtube channel: www.youtube.com/arcdroidcnc

CALIBRATION TRIANGLE

Assemble the Calibration triangle according to the diagram shown.

Take note of the numbering and arrows on the triangle rails. They should be facing upwards.

Use the calibration points to secure the rails, with the points facing upwards.

If assembled correctly, the triangle will lay flat on a level surface with the numbers and calibration points facing upwards.

CALI BRA TIONSLED

The calibration sled is a tool used to guide the ArcDroid™ through the calibration process. Before using, it must be adjusted.

Place the sled on one of the rails, and check for fit.

Using a philips screwdriver, adjust the screws on the side of the sled until the sled can slide smoothly along the rail without rattling or wiggling from side to side.

PLASMA TORCH ATTACHMENT

A firm, straight connection between the plasma torch and the Arc Droid™ is required for best results. Loosen the nuts on the torch mount enough to slide in the end of the torch.

Insert the torch into the torch mout, and align the body of the torch handle to be approximately parallel with the torch mount.

Ensure the torch head is aligned vertically while tightening the nuts on the torch mount.

Tighten the nuts on the torch mount until a firm connection is achieved. There should be no wobble or flexing between the torch and the torch mount.

NOTE: Is is best to clamp the torch on the fixed part of the handle, not on the removable cap

ARCDROID ™

Place the machine on clean, flat and level surface. A workbench or piece of steel is ideal.
Ensure the Arc Droid™ and table surface are level.
Use flat surface on the top of the Arc Droid™ arm to check the level.

If possible, clamp the ArcDroid™ and triangle to the work surface so that it doesn’t move during calibration.

Place the assembled calibration triangle in front of the machine in the correct orientation, and clamp or secure in place.

Attach the stylus to the Z-axis plate and secure with the locks. Do not plug into the Arc Droid™.

Place the calibration sled on the calibration rail at position 1. The pointed end of the sled should point in the direction of the rail towards the Arc Droid™.

Plug the calibration sled into the connection on the side of the ArcDroid™.

To begin the calibration process, power the machine on, and access the routine via SETTINGS then CALIBRATE The software on screen will guide you through the process.

Tips for Calibration

• Gently maneuver the ArcDroid™’s arm so that the end of the stylus is directly above the cone on top of the calibration sled at position 1.

• Twist the knob on the screen to lower the stylus point until the point is centered inside the tip of the stylus. You may need to adjust the arm position while lowering the stylus.

• The stylus tip, calibration sled, and rail should all be firmly in contact.

• Using steady, firm pressure, slide the stylus and sled together down the rail to the next position.

• Note the numbered location and and arrow indicate the starting position of the sled, and the direction of travel.

• Once the stylus calibration is complete, remove  the stylus.

• Install the torch on the Z-axis. TORCH MUST BE OFF OR DISCONNECTED FROM POWER.

• Gently maneuver the ArcDroid™’s arm so that the cone on the top of the calibration sled is in contact and centered in the hole of the torch.

• Follow the on-screen instructions as before.
  

• The universal torch mount can be removed and reinstalled from the ArcDroid™ without the need to recalibrate, as long as the cutting head remains firmly attached to the universal torch mount.

NOTE: Calibration should be repeated each time the torch is removed from the torch mount.

Z-axis c

Z-axis calibration is done to ensure accurate height of the torch tip above the work piece. To complete this process, you will need a small piece of material of a measured thickness (3mm-7mm is good) to be a height gauge.

• Install the stylus on the Z-axis and plug the cable into the connector on the side of the machine .
  

• Power ON the ArcDroid™ and when it is completed booting, press the HOME button

• Move the stylus to a flat area in the middle of the work surface, and press ZERO

• Press TRACE Trace then Shape Then press the circle icon Finally press the button on the stylus and choose a small diameter circle roughly 10mm.

• Press SETTINGS

• Clear Z should be set to the thickness of your height gauge. Press OK

• Press EXIT EXIT to return to the main screen.

• Press RUN and the ArcDroid™ will run the program.

• Place the height gauge under the tip of the stylus and check the difference between the top of the gauge, and the tip of the stylus.

• Press Settings then Machine Settings

• Scroll down by pressing the down arrow, to find ‘Probe Offset’ and press it.

• Change Z axis value to reflect the difference in height between the tip of the stylus and the height gauge.

• Exit to the main screen and run the program again. Use the thickness gauge to check the updated height and repeat the process if needed.

CONNECTING A PLASMA CUTTER

WARNING
ArcDroid™ is not compatible with High Frequency (HF) plasma cutters. If you are unsure if your cutter is HF, consult the manufacturer of your cutter.

The ArcDroid™ uses a simple two-wire interface to turn your plasma cutter on and off. Depending on the manufacturer and model of your cutter, adding this wire connection may void the warranty of your cutter, and may result in permanent damage. If you are unsure about any step of this process, consult a professional.

Before attempting this connection, we recommend you watch the tutorial on our youtube page at www.youtube.com/arcdroidcnc

Some plasma cutters already have an interface for this connection which makes the process simpler. Follow the steps below depending on which connection type you will be making:

Yes, my plasma cutter has this connection

• Depending on the type of connector your plasma cutter has, you may need to modify it to connect to the ArcDroid™.
• The trigger port connectors are located on the back of the ArcDroid™.
• For a firm, reliable connection, attach spade terminals to the end of the plasma cutter’s torch switch cable and attach at the indicated connectors. Polarity does not matter for the torch switch connection. Polarity is important for AUX 1 and AUX 2 connections. DO NOT connect the torch switch to the other connectors. It may result in damage to the cutter, the ArcDroid™, or both.

No, my plasma cutter does not have this connection

• In order to connect your plasma cutter to the ArcDroid™, you will have to access the trigger switch inside the handle of the plasma cutter. Be aware that opening and modifying the plasma handle may void the warranty and should only be done by an experienced professional.
  Please watch the tutorial on connections before attempting to modify your plasma cutter: www.youtube.com/arcdroidcnc

• You will need 16-18ga shielded wire approximately 8ft (2.4m) and two spade terminals.

• Open the plasma cutter handle and locate the trigger switch.

•  The switch will have two contacts. These contacts must be connected in parallel to the torch switch connectors on the back of the ArcDroid™. It is not necessary to disconnect the existing trigger wires in the handle.

• Once the trigger wires have been correctly identified, they can be traced back to the plasma cutter unit and wires attached to their terminals.

• It is highly recommended to watch and understand the video tutorial listed above before making this connection.

• Once the wires have been attached to the terminals of the trigger wires, they are ready to be connected to the ArcDroid™.

• Attach the spade terminals to the free ends of the wires.

• At tach the spade terminals to the back of the ArcDroid™ at the location shown in the above diagram.
