I’ve continued to edit this post, as I find answers to my own questions… I have italicized my most recent updates.
Got through SV04 setup, and have the pizza model in two colors with very good alignment, Yeah! I do have some remaining questions about some of the options.
- When Save is offered, I should use it to save any updated values, right?
I think I have that right. It’s just that I did not notice this step in the instructions.
- What is Initialize EPROM and when should it be used?
Sounds useful, but I didn’t have the nerve to select it. What does it initialize the EPROM to, factory settings, calibrations to zero, write current calibrations to the EPROM for permanent settings, or something else ?
Found that Initialize EPROM restores stored default values. So if this is selected, the printer needs to be set up again.
- What is Auto Z-level and when should it be used?
Sounds useful, but didn’t notice it used in the instructions. Is it measuring tilt of the X axis, to the bed? Does it then adjust the Z steppers to zero out the tilt? Or save the offset with auto level values? Seems redundant with auto leveling.
The Auto Z-Level feature levels the X axis by adjusting the right and left Z stepper motors based on the BL touch measurements. Seems to me you need to be sure that the bed is level prior to Auto Z-level.
