This is not an answerable question. It is like asking "exactly how far should I depress the accelerator pedal in my car in order to travel at 65 miles per hour?"

Each laser cutter is slightly different. The efficiency of the mirrors and lenses, the alignment, the performance (and age) of the tube, tube temperature, and uniqueness of the power supply will all come into play.

You will have to experiment and find the best settings for your laser.

Sorry!

Are you sure of the material that the heat transfers are made of? Be sure they are not PVC. I do not have much hope for cutting thru the material and not the backing sheet BTW.

Clearly you missed the point of Jeff's post. Your Laser is unique and the power settings at X % are only a guide if they come from others. The power curve to percentage is non linear just to make things harder.

As to your last post refer to what I have tried to add to Jeff's.

Best thing to do with a new material is 'test it' then carefully look at and 'record' what you see go up or down slightly from that point changing only ONE THING at a time and see if it is better or worse. Changing more than one thing at a time will send you in well over 50% of cases on the wrong path not an improving one.

Videos of this sort might help you along the way with your specific T Shirt job. https://www.youtube.com/watch?v=Vh14QfykTLM
