I finally solve my duale motors on my Y axis. But now when I try to work with my cnc it's like my work area is not set correctly because wen I send some draw to the cnc they give me error on the hard limit! the CNC goes on the oposite way of my drawing!
Do you have any clue how to solve that? I try with carbide create pro and easel but I can't figured out
Top left would not be normal.
You may have to tell GRBL that is where you want it with the limit switch mask as it is normally front left.
See "homing switch direction invert" S23
It is a mask that has bits to set the direction where home is.
Dont forget also to make sure you have enough "pull off" from hitting the switch.
3mm is a good starting point and can be reduced slowly from there until the results become erratic. Then increase them just a small amount again.
From the existing pics it look like you are going to home upper left but until you set the mask.
It will try to home to lower left.
You need to set $23 to 2
You can also set the travel direction for the steppers and invert that in GRBL as well if it helps with your orientation.
There is a similar mask available for that with $3 explained in this pdf.
It is normal to mount limit switches at the extremities of the travel btw so the Y limits would be mounted on the frame. Not a critical thing but a point to remember for future.
What software are you using as CAD itself is not always a sender.
In CAD software you can usually define the X, Y, Z, origin but it may not reflect the settings of the machine.
