I can use the CNC shield ver3 with estlcam, but how I can set the "home" for dremel and the "home" for laser?. For cut and engrave a panel I must assign two "home", one for the dremel and one for the laser and with repetier this is impossible (I think), and estlcam don't work with Ramps 1.4, how I can resolve my problem ( use of dremel and laser with the same tool). The problem is that the "center" of the spindle is different respect the center of the laser.

For this I use a support on the Z axis, where I installed the dremel together with the laser module. There’re 4 slots in the board for stepper motor drive modules, can drive 4 stepper motors, and each step stepper motor only need two IO port, that is to say, 6 IO ports can quite well to manage three stepper motor, it’s very convenient to use. I use MPCNC with a Dremel and with a laser module for cut and engrave acrylic panel. CNC Shield V3.0 can be used as drive expansion board for engraving machine, 3D printer and other devices. The movement on the axis are ok (if with repetier I move the axis X for 100mm, the mostly move the axis for 10 cm etc.), but If I connect the Ramps and program it with the function "arduino mega" in estlcam, the stepper don't work. You can watch a video on YouTube posted from GrblGru 5 axis CNC and this is link GitHub - gnea/grbl-Mega: An open source, embedded, high performance g-code-parser and CNC milling controller written in optimized C that will run on an Arduino Mega2560 for 3 axis they are both working with ramps 1.4 board.

Second associated problem is that the code seems to run twice when I try to use the serial monitor in Arduino Web Editor. The ramp's work perfectly, I use it with Marlin firmware, Aspire and Repeiter and it work very fine.
