My omtech Polar has a digital read out on machine that shows a number with “mA” (assuming correlated to power) the slower I go the lower that number, regardless of my “min max” power settings. I cant get it above 20 on the read out. Its been awhile since ive used mine.
I feel at one point I turned something on or off that gave me more manual control to that. I cant get through 1/4 birch with multiple passes. (Gets close). Tried many different feeds/speeds power.
I think you are confused about the readings.
mA reading is power required to do what the machine is performing currently. When you slow the machine it requires less power to do whatever task you have applied.
I am going to assume you are using 1/4" Baltic Birch. It is difficult to cut through because of the glue used and how the material is manufactured.
Not familiar with the Polar. Do you have a supposed output of 40W? You will likely need slow speed such as single digit with 80% power. I have a 60W OMTECH.
I cut 1/4" with speed of 7 and power of no more than 50%. High power settings (80%-90%) will shorten the life of your CO2 Tube.
Be aware my answers here are assuming you have a CO2 laser.
Others on the forum can probably help you more than I.

TY Ferg. mA and lasering is still a little foreign to me. It is a 50w CO2 yes. So I do understand slowing it down requires less power. I’m curious if there is a way to manually control that. Example I slow it down a little but force the same power?
