I added an air router to my printer and moved the end point. How do I modify where my impression zone begins?

Posted · I added an air router to my printer and moved the end point. How do I modify where my impression zone begins?

I added a metal piece to the structure of my Anet A8 with the propose that the new air rowter don't crash whith it, in this way the x axis end point sensor stops there. It works, but the printing area moved 20mm. Everything I want to print appears 20mm moved, before I only ran the piece 20mm outside the printing area in Cura and it was printed as I wanted, now it is not possible to do this.

 

How can I modify where the print zone really is?

    It's all about the build plate size and the Home Offset X value.  In Cura, the build plate size is in the machine settings.  in the printer the home offsets are changed using M206 and then saved to memory with M500.  When you change the Home Offset, you effectively move the build area because the printing 0,0,0 changes.

     

    A picture or two would be good.  It's hard to get a feel for what you need to do.

    Hello, thanks for answering. I did not receive the email with the notification.
    I attach images for a better explanation,

     

    This is how I plan printing.
    x = 0
    y = 0
    z = 0

    And this is how it prints.

    x=20

    y=0

    z=0

    Since i moved the point where the end point touches, the entire print shifts 20mm to the right.

    I think this is similar to what a dual extruder machine has to live with.  You have an offset between the nozzle and the router bit.  When the machine is set up as a single nozzle then the router is wrong.  When it is set up for the router then the nozzle is wrong.  What software are you using when you router?

     

    Post 2 pictures of the printer.  One with the print head in the Home position on the left and one with the print head as far to the right as it will go.  I need to think on this.

     

    These are just musings...

    You may end up adding a second printer to Cura that is the router configuration.  The first printer would be the FDM machine.  I think your going to lose 20mm of the width from the build area no matter how you end up configuring the machine in Cura (or any other slicer).  The important part will be that whether you are printing or routering that the machine head moves to the max limits without crashing into anything.
