Hi,
Just did a deep clean on our machine and noticed the coolant in the laser tube looks tinted yellow. Has anyone seen this before? Should I be concerned?

It almost looks like rusty water.

Are you sure it’s inside the tube? Yellow and brown gunk builds up underneath the tube, on the metal gantry it’s attached to, which you can see through the glass.

@dan84 yes its inside the tube. I noticed it after cleaning the machine. I take a piece of painters tape with a wife, and fish it under the tube to clean all around it. So it’s not the underside thats dirty and reflecting.
