Program zero is too low?

[markj (Mark Johnson)]

After changing out the VFD spindle for the mini router, the bounds check message states the Project will plunge to the bottom of the machine (Z-); The program zero is 1.5mm too low. I don’t understand when both thickness and cut are the same 12mm. The file is only 2 toolpaths and attached. Any suggestions? Thanks

Is the mini-router shorter than the VFD spindle? Will the machine move to the depth you want?

That message uses the machine zero, the machines Max Travel parameters, and the envelope of the toolpath to determine if any point in the toolpath would place the machine “out of bounds”.

To work correctly, the “Bounds Check” needs to run AFTER the zero has been set. If you load the toolpath before setting zero, the message means nothing.

that makes sense, thank you.
