Steps per mm, in Configuration.h of the firmware need to be cut in half.
Perfect. I’ll try it as soon as I get home.
Thanks again,

And likely yes, you have A4988 drivers instead of DRV8825. The former will only do up to 1/16th stepping and the latter support 1/32.
That’s what I was hoping it was. I just wanted to be sure it wasn’t an error on my part. I’m doubting I would notice a difference in resolution with that small of a difference, but if I ever needed to, I will get the correct drivers. Those are what started my little fiasco in the first place.

Hey guys.
I just wanted to thank everyone for the help. Cutting the steps per minute in half seems to have fixed everything. It was pretty exciting seeing it draw in the correct scale right on to the foam board.
The more I read up on drag knives the more I think tangential is the way to go. Once someone has an easy plug and play firmware, I’ll give it a shot.
I ordered a 1/32 end mill and need to pick up a router and print the mount and give routing the foam a try next. It would be cool to get some planes cut out and glued up for when the wind stops around here and see how they do.
The end goal was to rout the parts for the Low Rider out of aluminum to build a cnc plasma cutter, so I’ll work my way up to that starting with some wooden stuff until I get some confidence.
Anyway, thanks again to all. I’ll post a pic of the plans it drew out from my phone.
