Z Axis Controller Replacement
(I have elaborated on the control system used in this project over on instructables) The Z axis control on the Lasercut system has some features I don't really like. It's slow when you're trying to go large distances. You have to be right at the top menu before you can enter Z mode, but the top menu and the one below it are both identical so you end up pressing escape before hand just to make sure. Once in Z mode pressing escape does not get you out of Z mode, only pressing Z again does. Holding the Up/Down button for 3 seconds switches to a faster speed but this typically occurs once you reach the exact spot you wanted to be in and the Z zooms out of the desired position. You can't adjust the Z axis while the program is paused, meaning you have to stop, adjust and restart whereby you double cut a series of lines. If you don't datum the Z axis, which it doesn't do automatically, the Z doesn't even run continuously. Check the end of the vid
