Steps per rotation help

First, Happy New Year! I have a 90watt Chinese 6040 laser with a reci tube and Ruida controller. I just bought a roller rotary attachment, the one with wheels, not hotdog rollers. My problem is that I establish the correct steps per rotation in Lightburn, and with the same settings, the steps are different to achieve the same shape the next time I turn my laser on. This is with the same size tumbler. I re established the steps again, and each time, it is different. Not sure if it’s me, or my laser, or the software. Need some input please.
