Y homming fails
I have a 235/235 bed, but for the moment I can only use X 235 / Y 193.
I have attached the file printer.cfg where we can see that I have set the dimensions of the bed and the endstops positions.
I can do home on the x and z axes without problems, z tilt works without problems, but on the y axis I can't make it work in any way.
When I run the y home command, it randomly hits the endstopswitch as if it wants to go further as if it didn't exist, or the bed lowers a few millimeters and then gives me the error from the attached print screens.
I tested the endswitch by hand and it appears that it is triggered, I can move each axis in the correct direction....
Can someone help me and looks in printer.cfg and tell me what I'm doing wrong?

position_min: 45.4 # Y dimensions 193mmyet in your picture you can see it is trying to go to 45.350 instead of
position_endstop: 45.5 position_min: 45.4 # Y dimensions 193mm position_max: 235it should be
position_endstop: 0 position_max: 193and then you need to move your Y endstop so that it triggers at 193

This is my situation
yes, you need to adjust the max of Y. the bottom left in your printer is 0,0
thank you very much for clarifications 🙂
I made the suggested changes, but now when I run the Y home command, the bed lowers a few millimeters, then the attached error appears, without moving the Y axis.

if I manually push the Y axis until the endstop is triggered and then run the Y home command, I get this error

screenshots don't help, you should always upload your full printer.cfg after making a change for us to help
the bed is supposed to drop a few CM so that the hotend doesn't hit it
this is the actual printer.cfg
did you physically move your Y endstop so that it triggers at 193?
yes, I think it's drop 15-20mm
the homing sequence doesn't know where you are in Y. So it tries to move towards Y max (in your printer.cfg 191) until it hits the endstop. Once it hits the endstop it knows it is at Y max. If it doesn't hit the Y endstop after moving 191, it will throw that error
This is my y endstop

at this moment if I run the command y home the Y axis does not move at all, the z axis goes down and then the error appears
from what I understand where the endstop is now is 0, and on the opposite side is 191. Shouldn't the y-axis go to 0 instead of going to 191?
no, it homes towards Y=max not Y=0
just saw this
position_endstop: 0.1this is wrong, it should be
position_endstop: 193
yes, now it works perfectly 🙂
Thank you very much
