[Grbl_Esp32 Issue#516] Limitless motions

Hello, I am planning of using Grbl_Esp32 to control 6 stepper motors for a dosing machine. I would use relative distance movements, where distance corresponds to the dose.

Grbl seems like a good choice because it is capable of handling several axes in parallel, but there are a couple of things that worry me:
– the motors will always move in the same direction, could this cause problems with the coordinate system, like overflows in the counters?
– there is no need to handle limit switches or other additional functions which are normally found in a CNC machine, how difficult is it to disable all checks in Grbl?

Of course I could try it, but before embarking in the project I would like to get some advice.

Thank you very much
Giovanni
