When I cut the holes for my PVC fence I put them about half an inch too close to the front of the machine.
When I clamp there is not enough space for the back of the clamp. I will make some more appropriate pieces to serve the need but in the meantime I use some measurement blocks to fill in.
Thanks for the heads up. I haven’t done that but I could see myself doing it. It’s always cool to see people post their mistakes online to help others.
