Speed changes power not power?

I *have a very strange issue
In both lightburn and rd works the speed changes the output power of the laser ? I have a rebuilt 6040 ten high laser upgraded with a Ruida controller. I installed a milliamp meter and now to the wired issue
If I say cut a circle 10 mm sec at 40 % power I get 5 m/a if I up the power I still get 5 m/a and not a deep cut at 10mm a sec , however I changed the speed from 20mm a sec to 20 and noticed the m/a read 10m/a
If I put the speed to say 80 mm a sec the m/a meter is off the scale and power output is great and cuts much deeper
Any one have a damn clue what’s going on
