CNC Foam Cutter Easy Axis Direction

Always make sure your control and the drivers are not powered on.. you would probably blow the driver if you ever forget to power it off... remember the motors are energized when sitting

I don't know if this a stupid question or what but if I don't use limit switch in that case can I use homing option for my stepper motors?

You won't be able to Home the machine but when you power on that will be the zero origin for all the axis. So you you just use Go All to zero Hope that helps Keith

Hello, I am currently building a 4-AXIS Arduino CNC Foam Cutting Machine. However, I'm encountering some issues. The issue I am facing is that in the GRBL Software, only 3 Axis are showing. The U axis is missing. Do you have any idea how I can solve this issue? It would be great if you could assist me with this. If you are interested, please share your contact information. I would be glad to connect with you.

Follow the instructions here with the latest firmware and software.rckeith.co.uk/grbl-hotwire-mega-5x-for-cnc-foam-cutters/ The U axis is for the older firmware and software
