Teacup doesn't seem to look at the endstop signal

Anyway, in home.c, there are two errors in lines 82 and 88

Either the config.h for RAMPS 1.2 need to be change so only the *_MIN_PIN parameters are defined and/or lines 27-31 of the home.c code need to be rewritten so that the z is consistent with the other axes

My reason for doing this is to see if Teacup can execute G-code faster than Sprinter since it uses integer math.

i'm still bother by the fact that microcontroller/firmware can't seem to keep up with short segments. So far, I haven't seen an improvement when run without acceleration.

Without acceleration, stepper motors simply can't get up to their maximum speed for mechanical reasons, so if your motors move without acceleration you're far behind what's possible. More likely, communications over the serial line is the bottleneck here. Raising MOVEBUFFER_SIZE in config.h helps a lot, you can raise it up to the point where 90% RAM are used. "make" in the command line will report RAM usage.

marlin and sjfw have this capability, both based off grbl as far as I know

What else can you do without straying from the correct trajectory?

everything works great but shuts off after 30 seconds if I don't move any axis

With either or both heater turned on, it still turns off after 30 seconds.

I think eeconfig could be generalised to a runtime configuration system

#define STEPS_PER_M_X (5023*MICROSTEPPING_X)with
#define STEPS_PER_M_X 80368i.e., calculate the value manually and insert a single number only. It's a bit disappointing the preprocessor can't so this for us.
