Move Z Sensor Position

Hi All,

 

 On my Tronxy X5SA Pro, I plan swap-out the stock (PL-08N), Z axis sensor for one that detects at a greater range to use a glass bed.

 

 The problem with this, is that the sensor also detects a greater range around the side.

 

 This may involve having to reposition the sensor on the other side of the carriage, making about 60mm inwards on the Y axis from where the stock sensor normally sit's. This may then make the auto level not detect on the back of the bed, as the sensor will be over hanging the bed.

 

 I've had a quick look in Cura, but I don't see away to tell Cura that the sensor's position has change, or even to create a new profile with an offset.

 

 Is there anyway to do this, or a work-around?

 

Dizzwold.

    On the one side there is a switch, and on the other side there is something acting as the trip dog.  It is often easier to change the trip dog.

    Here is the fix for my Ender.  The gray clip is easily removeable so I can take the glass off and go back to the magnetic pad.  The narrow finger sticking out on the bottom of the clip is the piece that hits the switch.  The thickness is the difference between the glass, and the magnetic pad.  With the clip in place - the switch is tripped about 3mm short of where the actual frame piece used to trip the switch.

     

    Cura doesn't know or care where the build plate is.  Cura does need to know how big it is.  I don't know on the Tronxy but the Home Offset numbers usually set the local 0,0,0 and then when the gcode comes into the printer, that's what is used as the origin for the print.  I suppose you could go into the machine settings and make the "Z" Max 3mm shorter.  I didn't bother and I don't think Mr. Spock is going to show up and yell at me.
