I need some help #350

Closed srmarkovic closed 2 months ago

srmarkovic commented 9 months ago

I made custom board for Atmega2560 grbl controller for my hobby machine. I used pinouts shown in the bottom picture. It worked fine with grbl/Mega. I need 4th axe so I tried your 5X grbl. It works fine, does homing, shows when limit switches (inductive with isolated 24V psu, shielded cable optocouplers and smit trigger circuits working beautiful) are triggered but doesn't halt doesn't invoke Alarm. I tried with "#define ENABLE_RAMPS_HW_LIMITS " and it cant send pulses it stucks or does something strange. Please help me. Where did I go wrong. Thank you. Here is my cpu_map.h GRBL Mega 6 Axis

/ I made custom board for grbl. I used next pins : Limit Z 12 Limit Y 11 Limit X 10 Mist 9 Flood 8 Spindle PWM 7

Hello! Just a quick (stupid) question: Did you think of enabling hard limits? ($21 - Hard limits, boolean). I think they are dsiabled by default...

Cheers Raphael

Cheers Raphael They are enabled.

When I don't use #define ENABLE_RAMPS_HW_LIMITS everything works and it is detected when limit switch is active (show RUN (x), RUN(y), RUN(Z) according to axe limit activated in BCNC or when it is not in run state and I ask $$ ) but there is no Alarm and machine continues to work. When I use #define ENABLE_RAMPS_HW_LIMITS there is alarm and machine stop when limit is activated but it loses steps jogging or stop or uncontrolled continue to go in one direction and do all kind of weird things and it is as it has no power.
