The following G and M codes are supported by the Control Interface. Click on the Command name to get more information and examples with the command.

You can find more extensive examples on G-code in the [[G-code examples]] page.

== Comments ==

Writing comments in your g-code can be helpful in keeping track of each line. Comments will also let you "comment-out" a line, so that the line is ignored.

To comment out a line, add a % sign to the start of the line.

The TechnoCNC interface will ignore all lines that begin with a asterisk *, open parentheses (, percent %, and forward slash /.

Remove the motor

2012-05-08T18:31:07Z

Efeldman:

To remove a motor:

* If the motor to be removed is the Z axis, [[Chock up the Z slide]] so it doesn't drop when the motor is removed.
* [[Lock out power]] to the machine.
* Disconnect all cables going to the motor

If the motor is connected to the axis by a belt:

* Unscrew the motor from the mounting plate
* Remove the motor and belt

If the motor is connected via direct shaft coupling:

* Unscrew the bolts that hold the motor to the machine via the coupling housing
* Pull the motor away from the machine

This section will be expanded with images and more instructions shortly.

Plasma Troubleshooting

2012-04-24T18:56:41Z

Efeldman:

== Plasma Posts for CAM ==

Use a standard Post processor for CAM software. The techno software interprets standard techno gcode.

Be sure the plasma pre-preprocessor has been implemented. Press and hold the preprocess button and make sure that plasma is on the active side of the pre-preprocessor list.

== Consumable replacement ==

Replace all consumables at once, make sure the new ones are a matched set, rated for the amperage they will be run at, and installed as per the manufacturer's instructions.

== Work lead ==

Be sure the work lead is attached to the part to cut and not only to the table.
If the work lead becomes separated from the part being cut (either not attached or cut free), several issues may arise, including torch not starting, intermittent torch errors, premature consumable wear, poor cut quality, etc.

== Air Requirements ==

The air pressure set at the torch must be set properly (consult the proper pressure for the material being cut in the manual

The air flow must be at least as high as the torch minimum (consult the manual, it is typically at least 6cfm. Techno has a flow meter that can be borrowed to test if necessary)

The air must be clean and dry! Employ air filters and water separators/dryers. Keep in mind that some dryers restrict flow too much and could result in too low of a flow.

Marking pulleys is used to determine whether or not the pulleys are slipping on the motor or ball screw shafts. Drifting pulleys can be responsible for [[Drift_test|machine drift]].

'''Step 1: Mark the pulleys in one of two ways:'''

'''NOTE: THERE IS A MARK ON BOTH THE PULLEY AND THE SHAFT INSIDE THE PULLEY.'''

'''NOTE: MARK BOTH PULLEYS IF PRESENT - THE MOTOR SIDE AND THE BALL SCREW SIDE. IF THERE IS ONLY A SHAFT COUPLING, MARK BOTH SIDES OF THE SHAFT COUPLING.'''

[[File:marked shaft end.jpg]]

[[File:marked shaft side.jpg]]

'''Step 2: Run the file or perform the operation that would cause the drift issue.'''

'''Step 3: Check the pulleys. If the lines no longer line up, the pulley has slipped. Remove, inspect, replace if necessary, and reassemble properly to prevent this from happening again.'''
