Emco F1 CNC modernización (retrofit)

Thank you, very interesting ! If I may ask one more question: do you control the enable input via software, or do you enable with a physical switch connected to a relay ?

Hi Eddie

Yes, it is a relay switch activated by the control board.

Hi Hugo,
Okey, thank you for your answer. I don't really see what i will need the enable signal for, why can I not just keep it enabled by keeping the original jumper wire?

Oh, and did you not ground the spindle motor to the GND port, next to EN port? Did you connect it elsewhere? See image of how I have connected mine so far. It works very well by using the potentiometer that it was supplied with, but I have yet to try it with PWM from Linuxcnc.

The spindle can be permanently turned on with the jumper wire, but it will rotate from the moment you turn on the router, which is not convenient. Instead of the jumper you can put a switch and turn it on and off manually. But if you want the spindle to turn on and off via LinuxCNC with M3 and M5, the relay option is the good one.

I have the entire structure of the milling machine connected to GND, so the motor is already connected to GND. I have the power connected to GND (green-yellow cable). All control signals I connect with two wires: GND + signal.

You were right about the spindle staying on without an enable signal
I was just given a 5V reed relay from a buddy of mine, which I connected to the spindle enable signal from LinuxCNC and ground on my HobbyCNC board (and EN and GND on the motor driver). Now I have spindle control! I've also got the steppers going, so very soon I will be able to test some machining.

Thanks for all your help, again!

Hola compañeros.
Os comento como coloqué la pantalla y el teclado ya que por temas de espacio quería que estuviera todo integrado a la máquina. No me convence demasiado, pero por el momento lo tengo así hasta que vea claro otra solución.

Puedes usar pantalla táctil y usas la version Beamicon2 touch.
No hace falta mucho el teclada ya... y raton/trackpad puedes olvidar totalmente.

Gracias Ingolf, miraré la versión touch que me comentas.
Aprovecho para poner un video de un par de mecanizados con la máquina tal como la tengo ahora.
