For now just a unorganized pastebin to document things that don't fit the mastodon account.

Rotary Engraving
Get the rotate engrave tool and put it in the lasercutter (in a way where the wide side faces you). Align it to the X axis of the lasercutter. Connect the two cables to the two plugs on the upper right side of the inner workarea (labeled 'rotation'). Flick the Axis Y/Axis U switch on the side of the lasercutter to the 'Axis U' position. Turn the lasercutter on. Test if everything is working by moving the y axis. If the rotate engrave tool moves you're good to go. Move the laser over the object you want to engrave. Be sure that you are exactly in the middle of the object on the y axis. If the laser hits the object, press reset, the laser will move the z axis down. Repeat as many times as needed. In the driver software, enable rotate engrave in the 'Output' Tab. Set circle pulse to 7600 and enter the diameter of the object. Enter the speed an press 'Test'. Ensure that the object does not fall after rotating 360°. Proceed as you would normally when engraving.
Reverse Engineering
Driver (LaserWorks aka RDCAM)
Nope.
Communication Protocol
The protocol can be used in 3 ways.
- USB
- Network
- By saving the job to a file in the driver.
We didn't get the net- to work (haha) so we are using USB right now.
Setup Messages
Before sending the job to the lasercutter the driver sends and receives a few preflight messages. We are unsure if the change when using the Network but they are omitted when saving a job to a file.
