Arduino Uno R3 + Arduino Motorshield Rev 3 + Grbl
Posted: Sat Feb 21, 2015 11:12 am
Hi,
New here and thanks for an excellent resource.
We've decided on a dlp printer as a possible project in our makerspace and have a spare Arduino Uno and the official motorshield Rev 3 with a NEMA17 stepper. I was wondering if anyone has played around with this config for a z-axis control for a dlp type printer?
Grbl firmware assigns the pins D12 and 13 on the Uno to the spindle. Would it be as "simple" as editing the pin mapping in Grbl and compiling & flashing to the Uno to use the motorshield?
Or is there a more straight forward way using this type of config? We're hoping to use Creation Workshop as the eventual control software.
Any comments, suggestions and advice would be greatly appreciated.
