see [Hardware - Maslow CNC Forums](https://forums.maslowcnc.com/c/hardware-issues/8#:~:text=Added%201%20Metre,calibration) for a way to extend the belts. That method assumes that the extensions stay flat (do not angle up from the ground) ---

Thank you. Good to know there is a limit. I know that the belts would need to be longer to do whole cuts, I was just trying to get the thing working at all even for a small area. Bought some wood today to make a frame. I don’t have space where I can glue permanent anchors or store a big frame easily so that I why I am trying to figure out something else. This seemed easy. Nope. ---
