Strange behaviour: Lower power at low cutting speeds

I was cutting some thick material so had the speed very low (8 mm/s) and power at max. The tube was only pulling 10mA instead of the 25mA it should have at max power and so wasn’t cutting through the material.

When I brought the speed up to 15 mm/s it was pulling 25mA as it should.

The power was continuous (long, straight cuts).

I never cut this slow before so don’t know if it’s normal for the power to be adjusted when cutting at low speeds. Is there a setting that controls this? I went through the machine settings but didn’t see anything relevant.

These were the cut parameters:

Thanks. It was doing the same thing in RDWorks so I didn’t think it was an LB issue. I’ll try changing that parameter…
