Y axis configuration

Hi, I've been trying to configure my Y axis on a bf20 type milling machine for a few days now.
I've read a lot on the forum, but I'm not able to configure it the way I'd like.

I understand that the Y axis, when the spindle moves away from me (or the table moves towards me) should be positive. That's what my Y axis does
I have an inductive sensor installed as a switch for both limits and home. When I search for home it goes to the negative side and I want it to go to the positive side.
I've tried HOME_SEARCH_VEL = 10.000000 and it goes to the positive side, but after home it always hits the hard limits when I get close.

Another issue is that I'd like to change the direction I move the table on the Y axis with the keys. When I press the up arrow I'd like the table to move away from me. 

#*** AXIS_Y *******************************
[AXIS_Y]
MIN_LIMIT = 0
MAX_LIMIT = 144
MIN_LIMIT = -144
MAX_LIMIT = 0

[JOINT_1]
MIN_LIMIT = 0
MAX_LIMIT = 144
MIN_LIMIT = -144
MAX_LIMIT = 0

Rename attachement keybingdings.py.txt to keybingdings.py
Place into your /config/ folder.

Hope this helps.

It works but i have had to change HOME_OFFSET
HOME_SEARCH_VEL
HOME_LATCH_VEL

for positive values and everything perfect.

I think the same thing is going to happen to me with the X and Z axes.

When I install the limit sensors
i will test it and comment.

thank you so much.

Yeah can be confusing those MIN/MAX, pos/neg, sensors, logic levels, it's endless. Took me a while to set-up my mill correctly back when I've introduced Lcnc to it.

Shout out if you're stuck. Pleasure btw, be safe and have fun.

Can you tell me with an example how to do a key remapping?

See bottom of first answer and the attached file there.

Yes, I did that. The file with the modification that the colleague made works perfectly. 


I am referring to an example of how the file is modified to reassign a key, so that I can reassign the keys that I need.

Not sure if you are aware of this but these are the only relevant lines in the posted file.

Everything else are comments as examples.
So basically you need to 'unbind' the keys you want to reassign and then assign the function.

Finally, I have all the axes set up correctly. I also managed to remap the X axis keys

Thank you all very much for the help.
