ignore limit switch do not work was created by wbeppler
hello,
if my machine moves to a limit-switch i can not drive free by "ignore limits".
i only connected my pos and neg switch to only one input and i did try
net z-pos-limit hm2_5i20.0.gpio.061.in
and i changed to
net z-neg-limit hm2_5i20.0.gpio.061.in
both time same problem.
my 1st question:
if i'm on pos-limit, i only can travel to neg-direction ?
my 2nd question:
is it necessary to cut the hardware-wire of the switch to free my axis ?
is the "ignore limits"-button (i hope i write it correct because in german the is a "Grenzwerte aufheben") connected to a output where i have to connect a relais to cut the limit-signal ?
how to manage this problems ?
thanks
wolfgang

If your limits are shared program something like this
net both-home-x <= parport.0.pin-10-in-not
net both-home-x => axis.0.home-sw-in
net both-home-x => axis.0.neg-lim-sw-in
net both-home-x => axis.0.pos-lim-sw-in
This way EMC knows you have only one switch and will allow you to jog in any direction to get off of the switch.
