This simple tutorial employs and explains the main functions of the Techno CNC GCODE Interface by running the sample program, 2box.nc. If you have any difficulty with the tutorial or are just learning to use your machine, we recommend reading the manual completely before proceeding.
Note: This Tutorial was written assuming you have already setup the touch pad and have a tool loaded.
Start the Interface
From your computer’s Start menu, choose Programs/Techno Servo Interface.
The Techno CNC Interface Main Menu appears:
Note: This tutorial is written assuming your X/Y Machine Orientation is set to the Interface default setting of -1 If this has somehow been altered, go into SETUP/SYSTEM and make sure the X/Y Orientation is set to -1.
Home the Machine
Press Home. The home menu appears. Press All.
Zero the Z-axis
Prop the touch pad on top of something high enough so that your Z-axis zero position is well above the table surface (see picture below). Do this to ensure that the tool does not travel into the table surface. The prop height is supposed to represent the height of the material to be cut. After you zero the Z-axis, remember to remove the prop.
Jog your tool over the Touch Pad.
Note: Prior to Zeroing the Z-axis, we will test the touch pad and see if it is working properly. Follow the Steps and Warning below.
The Test
Here we will start the Touch Off Process. The Z-Axis will automatically travel down to the Touch Pad. If the Touch Pad is working properly, once the tool comes into contact with the pad, the Z-axis will retract immediately. Our test involves the user manually bringing the Touch Pad up to the tool during the Touch Off Process as the Z-axis is descending (see picture below). When you lift the touch pad up to the tool, if the Z-axis retracts, then the pad is operational. If the Z-axis DOES NOT retract, then IMMEDIATELY press the ESC keyboard button to stop the Touch Off Process. Then, check your touch pad setup before returning to this tutorial.
Press Touch Off Z Zero Position. The Z-axis will automatically descend.
Manually lift the touch pad to the tool and then gently touch the pad to the tool.
Note: If the Z-axis retracts upon contact, continue to the next step. If it does not retract, check your touch pad setup before returning to this tutorial.
