Hello,


First of all I want to tell you that I am kinda newbie in this segment so be patient with me. I bought a year ago from a friend a pcb cnc from Cirqoid, a company that stopped the production kinda left this machine without support. It supports Cirqwizard the CAD program in order to make my PCB, but it has some limitations and I start to become nervous when using it. I want to upload on it a free open source firmware so I can use other CAD programs and also to make use of the autolevel function. The processor which is on it right now is a STM32F407. The problem which I don`t know for the moment how to solve is the closed loop magnetic encoder control. It has some magnetic bands along the axis and with a reader it gets the position. Can you suggest me a firmware close to what I need.

I will give any other details needed. In fact I don`t know exactly what is important to write down in order for someone to give me a piece of advice.

Alex.
