Hi all!
;currently tested (little by little
because I didn’t have much spare time right now…) and I have found at
least 3 bugs in the current design of the ControlPCB.
These bugs are easy to fix, but I’ll update the electronic design in order to have a bug-free PCB.
The bugs I have seen so far are:
- Solder
pads for the Power and Switch terminal blocks are in the incorrect
side. Quick fix: Solder it through the hole or applying some solder
paste in the solder pad before introducing the terminal block. - The
Tool control pin is currently connected to the Mega’s pin 40 which is
not a PWM pin. Quick fix: separate the Tool wire from the ribbon cable
and connect it to a free PWM pin (for example: pin 7). - LEDs are
too bright. I have to check the values of the resistors since the leds
are so bright that them can hurt the eyes. Specially the USB one. Quick
fix: Probably a higher value of the led resistors will solve this minor
bug.
Except for that bugs, the PCB works well.
I will upload soon the fixes, the grbl version for this board aaaaaand a diagram of the PCB connections.
Best regards!
