  • Is the reset pin only used for firmware updating? If I was to use something other than a pi (either UART directly or USB->(FTDI/CH340), can I get away with just TX,RX, Gnd, and VCC.
Yes, the reset is just for uploading via the Arduino bootloader.

  • I'm wondering why 3.3v and 5v are needed, and if I wanted to make a custom adapter board this would be very useful
3.3V is for the level converters with the RPI (3.3V) and the ATMEGA328 (5v).

The ATMEGA is running at 5V like most GRBL boards are

HI. If latest version of your Arduino CNC Shield is compatible with the TB6600 Stepper Motor Driver.

Thanks.
TB6560 seems to work better....

Re: Quick test with TMC2209 drivers

Hello, I just received the 3.51 board earlier than expected :-) and did some tests with the TMC2209 SilentStepSticks from Watterott with Trinamic drivers. They also fit on the CNC shield. As it turned out, it works without any problems together with an Arduino Uno R3, grbl 1.1 and standard NEMA17 s...

Tried the plug change, it had no effect what so ever.
I must point out that I made no changes to any connection, I just replaced the board and connected the drivers.
Am I missing something.
Is the current set on the drivers? Are they powered? .....

Re: Layout for 3.51

Just received my shield, and noticed the PCB is now at version 3.51 and doesn't quite match the layout shown - I assume the 'fuse' and resistor are no longer required? Or have been replaced by the SMD components? Other than that I guess the assembly instructions are the same? Regards Chris Yes. We ...
