3. The bit should be sharp. Pine is a strange wood with those alternating hard
and soft bands which tend to show up any flexing in the JGRO when cutting it.
I an not sure about your TCNC settings as I use Mach3.

1. I will try slowing down the plunge. I cut at about 20"/min but had the plunge set to 5 or 6 ( can't remember). I will try 3-4 tomorrow.
2. Looks tight.
3. Yes, I seen some flexing tonight. I agree pine is strange to cut. You can hear the router bogg down then speed up. I tried cutting circles with scrap MDF and still seen some flexing.
Thanks for the tips. I will try adjusting the plunge setting tomorrow.
