Ok so hopefully I can make this simple:
Material: 3mm Plywood (Bunnings) Yes I am aware this has glue throughout and is not good quality but I do not have issues with large pieces only these 40mm circles)
Cutting multiple circles
Historically 3 cuts standard to cut through
Lately it does not seem to want to cut through in 3 cuts, so I have added an additional cut but it it now seems to be burning the edges at 4 cuts.
If more screenshots required of settings happy to do so.
Hopefully someone in this forum starts typing frantically as they have the magical answer !
Any suggestions welcome
