Endstops are ignored

overdrive · August 2017

Hi
I have tried every possible configuration but I can not get the firmware to honor my endstops. They show up as H or L when I press them and check with M119 but the printer will not stop movement when the endstops are hit. Only when homing are the corresponding endstops honored.
Please help.

Here is my endstop section:

Firmware is any dev v1. Even tried it on the latest github code downloaded today

So G1 X-50 F600
does not stop while G28 X0 works?

#define ALWAYS_CHECK_ENDSTOPS 1
should make sure that G1 would stop in that case, also the move it self should already be prevented being outside of print area.

My specific concern is when the printer is started and it homes, the bed moves up by 10mm and homes x,y,z. if z is already at maximum it still tries to move 10mm up even if the endstop is hit. My understanding of the function of an endstop is to stop movement irrespective of what the command is unless the movement is supposed to be in the opposite direction. Pressing any endstop and telling the printer to move will result in that movement.

Not sure but you might be getting a conflict by having both hardware and software Z-max endstops enabled.

if you have a hardware endstop defined as true the corresponding software endstop should be false. If the endstop does not exist as hardware it is a software endstop. a M119 should show a high when the endstop is hit.

I guess you have no hardware Z max endstop so this can in deed happen. You can choose to not go up with z on homing to prevent this. The other solution is to reduce z length by that value so even at z max you could move 10mm up. Problem is when enabling printer it doe snot know start position so assumes z=0 and software endstops will not work at that position. They only work after homing.

Will update the firmware and test again
