I have a couple questions regarding this change…
I have the new Taz 4 style hardware installed on the Z axis. Is the only firmware change needed the z steps per mm from 800 to 1600? Is there something else?
Secondly, when I attempt to upload the firmware with modified settings, they don’t seem to save on the Rambo. The sketch compiles and uploads, the rambo restarts but the old settings still exist following the printer power cycle.
I am running Windows 8.1 with Arduino 1.0.5. The computer recognizes the rambo board on port 8. Everything seems happy but the settings do not stick.
Any ideas out there??
