I even noticed that the software limit is not working properly in the controller(or maybe I do all wrong as usual) when I enable the software limit and setup all the traveling limits, the machine do the zero properly, and then the axis start traveling to the setup limit and stop, no other chance to move the machine then, what I'm doing wrong now? Thank you for any help you can give me before I throw the controller in the bin and buy a professional one

There was something like " ignore limit when home" in the limits menu? Plus i have programmed there to retract 10mm back, i think that was the default.

Now there is an situation where when homing overshoots the 0 and enters in the soft limit zone. What it does then is start to go into the another direction towards the other end limit switch.

Hence generally i find that it's a good practice to disable SOFT LIMIT when homing and then enable it again once homing is done. Or lower the speed of homing so it will stop on time. problem on a big machine like mine, cause you have to wait a lot. Or enter 2-3mm negative soft limit, but problem is that at 4mm it already will hit the sensor.

So i disable soft limit, home and then again i enable it. Anyway, i don't switch off the machine all day long.

On the first machine i have done i had the limits so that they will not interfere with the gantry, but on this one i decided that perpendicular position will give me better accuracy.
