Sorry for this ridiculous question–I’m a beginner.
I have been experimenting/learning on 2” thick material and have done okay with that. Now I am trying to work on some 1” thick material and the CNC is cutting in the air–not the material. I have changed the material thickness where it allows you to do that and I am using a touchplate to find the 0,0,0 point at the top of the material, left corner but it still cuts the air not the material! I know there must be a ridiculously simple fix….
@kedge Hey, we all started somewhere. Welcome to the forum.
Which machine do you have?
Are you using gSender?
which touch plate?
Which CAM software?
I have the LongMill 30x30. I produce the drawing in Rhino, then I put it through SheetCAM and then to gSender. I am using the older touchplate.
@kedge Unfortunately, I don’t have any of those so can’t be of much help.
But I can offer this:
If you manually jog so that the tip of the bit is at the material surface (or whatever surface you zeroed to), does the Z coordinate in gSender say 0 ?
If yes, then I’m guessing your problems originate with your CAM software.
You could always run your g-code through https://ncviewer.com/ to see what it’s going to do.
@kedge What size tool are you using on that 1" material? I am asking only because, if your router is high in the clamp, you may be bottoming out your Z gantry, which will throw things off. Been there, done that.
Thank you so much. I’ll check on that.
