I hope someone out there has run into this issue. I have a Roland EGX-350 that I bought new. It has less than 200 hours on it. It was working fine Sunday morning, but when I finished one job and started the next one, it would no longer engrave past/deeper than Z0. It is like it isn't getting the pressure/depth instructions from the Roland Engrave Studio software any more?

It engraves just fine with the nose cone... but that sends no depth/pressure info to the EGX-350. I get no error messages - it just engraves the air right above the material. No matter how deep I set the depth/pressure it engraves exactly the same - never going any deeper that Z0.

I have swapped laptops to ensure that wasn't the issue (Windows 7 and Windows 11) - have the same results. I have turned the engraver off/on. I have tried a variety of files - same result. I have reset Z0 multiple times. The EGX-350 has the latest firmware. I am using the latest version of Roland Engrave Studio.

What am I missing? Thanks in advance!
