Mainboard v0.3 Power Check
I'm currently checking the mainboard, and ran across a small issue.
On the wiki (1) it says that only pin 2 of the MBED should have 5V. In my case I have also 5V on pin 10. On the pcb its clearly routed from 5V of the 7805 through R8. (The schematics pdf is too low resolution to be readable, but seems to agree).
So the question is if the above is correct or not. If not, the wiki should be updated.
The second question I have is about VSensor. How do I decide to use VCPU or 5V? (In my case, VCPU = 24V)?
Another question: My laser only has Xhome/Yhome sensors. If I wanted to add a Xend/Yend sensors, where on the pcb would I need to connect those?

Does someone have an answer to this?
