My employer has aquired a used Multicam 3000 CNC.

We are attempting to use it to cut panels out of Duraplate. The plate is just under 1/4" thickness.
Galvanized steel .0160" sheet on each side with a composite core of .2042" inside.

Our panels are created from Autodesk Inventor file masters, and saved as .dxf files.
We then are using EnRoute software to create files for the CNC. All the information needed for the router is saved to each file.
Spoilboard surface (has been fly cut) is good. Table vacuum is good. Panel is on the table and ready to go.

We connect a wired calibrating 'puck' to the CNC. Surface is set. Max depth is set. File is selected and and then run.

An EMC601604 1/4" carbide four flute endmill bit is used.

Cuts through first steel layer and through the core, but it will NOT cut through completely on the second steel layer.

We have to stop and increase depth incrementally through the control pad too many times.

Then eventually it will cut through, but then into the spoilboard.

Something somewhere is not calibrating correctly.

Is there data setting cached in the CNC's drive we're not aware of holding it up?

Calibrating puck defective?
