I would like to add a small display to ramps (http://www.ebay.com/itm/0-96-I2C-IIC-SPI-Serial-128X64-White-OLED-LCD-LED-Display-Module-for-Arduino-/201428440360?hash=item2ee6121528:g:MOYAAOSwv0tVeD0N)
Here I would like to show remaining buildtime from CW ...
Is this possible to do easily?
Or does it require a whole lot of programming / rewrite of both CW and Marlin FW.
I was thinking a custom gcode command to set and display the time.
(If I can retrieve the buildtime from CW that is)
You can discuss various control electronics here. RAMPs, Arduinos, Motor Controller boards & etc...
