== How to use the rotary axis attachment ==

* disconnect the Y-axis stepper driver (far right corner of the laser).

* place the rotary axis rig on the bottom of the laser. Align it with gantry (in Z and Y directions).

* connect the rotary axis stepper to the driver.

* in RDWorks software, go to File >> Vendor tools > Motor > '''Y axis'''. Press "Read" to read the settings from the laser. Press the Step size menu under "Contrl Mode". Enter 157 (100*\pi/2) in the lower (Measuring length) field. Press "Write" to upload the settings to the laser. Original settings are backed up at Desktop/Laser backup and on Github: https://github.com/Technariumas/LG1390N-laser-cutter

* Adjust speed settings (note the Y-axis) -- the workpiece can rotate too fast and fall off if the speed is too high.

* Insert your workpiece, focus the laser on the topmost part of it.

* Frame, check and burn.

* Reset the settings back.

* ''' ATTENTION: The laser head can hit the rotary rig if the laser is moving. Always be careful with laser homing/origin. Once set up, do not turn off the machine before using it. Once you turn off the laser, remove the rotary rig before turning it on again.'''
