I have an M2E printer, and I'm going to upgrade the firmware. I want to be able to test it a bit before I run a print, and was planning on using Pronterface. I've installed it, and set all the parameters I can find. If I click on the three "Home" buttons on the jog control wheel, all three axes go to the right place. The +/-X and +/-Y commands all work as they should. HOWEVER, I have no "-Z" option available on the wheel, and it's currently stuck with the platform down.
Any idea what I'm missing? As long as I manually raise the platform after the firmware update, I can still check that everything runs in the right direction, but I'd like to get this fixed for he future.
Thanks!
