Can I use two Uno CNC shields instead of building the Thor-specific PCB? #100

I did not try yet but I think this is possible, right? if so it saves a whole lot of time to mill the PCB with a CNC

Hello Daniel,

Yes, it should be possible, as common Uno CNC shields are capable of controlling up to 4 stepper motors. Back in time, I did something similar using 2 RAMPS Shields. You just have to keep in mind, that when sending the degrees of motion to the joints, you will have to split the communication into 2 parts. Probably one for the first 3 joints and one for the last 3.

Anyway, before you think about machining the PCB, take a look at the Thor Control PCB. You can order it from PCB manufacturers (PCBWay for example) and it doesn't cost much money, the only thing is that you will have to solder the components yourself.

Thanks, you are an angel. Will try!
