If so, should I introduce 3 new uint32 variables

z_counter and z_steps

G28 M117XYZ ;reset internal coordinates G1X100Y100F8000 ;some move G28 ; go home M117 ; print coordinates G28 M117 G28 M117Here is a conversation:
> G28 < ok > M117XYZ ;reset internal coordinates < ok X:0,Y:0,Z:0 > > G1X100Y100F8000 ;some move < ok > > G28 ; go home < ok > M117 ; print coordinates < ok X:-10,Y:-23,Z:0 > G28 < ok > M117 < ok X:2,Y:-1,Z:0 > G28 < ok > M117 < ok X:0,Y:1,Z:0Increasing ENDSTOP_STEPS improves accuracy significantly.
dz_um = (dz_steps*((1000000L*100)/STEPS_PER_M_Z))/100;Maybe there is a better way?
next_target.target.F = MAXIMUM_FEEDRATE_X * 2L;I know that the correct feed rate will be computed later, but on my machine this causes (e.g.) G0X200Y200 to move (after short acceleration) very slowly with a strange sound. Moreover, using aforementioned M117, I can show that no step were loosed. Removing "*2L" solves the issue. I suspect, there is a overflow somewhere.

In which units MAXIMUM_FEEDRATE_* should be, mm/min?

I just remembered earlier warnings for microstepping on Z, which can cause problems generating enough interrupts. is that still a problem?

Absolute E commands? Teacup stops working when this reaches 4300mm or something. Relative E commands work better.

Absolute extrusion means if a requested E move is to small for the extruder stepper to take it gets added to the next move
