Post by: inglis93 on March 27, 2020, 10:13:37 AM

hi everyone i am new here i don't normal join forums but i am at my whits end with soft limits i have tried every combination off setting i can find nothing is working so i am hoping you lovely people can shed some light on what i am doing wrong.

so here goes.

ref all home goes to bottom left and z goes to max up travel all homing switches are working perfect all dro's reset everything is good.

in homing and limits settings x and y are soft min 0 soft max 1000mm
z axis is -142mm min and 0 max  auto zero is on for all axis

z is reversed

i have also tried swapping values between - and +

i have turned off a axis is angular and rotational soft limits as suggested in another post online still no help

all i get is machine out of limits for soft limit activation

any help would be greatly appreciated thanks

if you go to diagnostic page you can see Machine Coords.
if one of These is out of the range you have defined in Config -> homing/Limits
you are not allowed to turn softlimits on, that is what the errormessage means.

It could also be a, b, or c axis out of limits. Make sure they are zero referenced. There is also an error in mach3 that will do this. To get out of it, you have to make a,b, and c linear axis (uncheck angular in config). Then in homing and limits, make sure they auto zero. Then reference all home. Also make all your x,y,z softlimit max .01. You don't want your machine "0" to be on the soft limit.

Post a picture of the machine with all axis at the home position.

Is the machine on servos or steppers?

If its on steppers swap 2 wires on the axis motor and turn off reversed option.  You will have to swap the homing too.
