Connecting Laser to miniRambo setup help

It still works for me,

#define Z_MIN_PIN 23
#define Z_MAX_PIN 10
#define SPINDLE_LASER_PWM_PIN 10”

We don’t have Zmax enabled so it doesn’t look for that pin. The physical zmin pin (probe) will now be Zmax signal. Z min will be your laser pwm.

I have these setting:
#define Z_MIN_PIN 23
#define Z_MAX_PIN 10

// Z Probe (when not Z_MIN_PIN)
//
#ifndef Z_MIN_PROBE_PIN
#define Z_MIN_PROBE_PIN 23
#endif

#define SPINDLE_LASER_PWM_PIN 10

So now I plug my Z Probe into the Z Max and my laser PWN into the Z Min S, right? Can I reconnect my LCD also?

Thank you so much Ryan.

You should only have to change the pins file. Nothing else. We shuffled the numbers but in terms of config it still thinks it is zmin.

We moved and sent the post office a forwarding address.

I just downloaded V1 Mini Rambo Marlin code, made the two changes I think are necessary, and it successfully compiled for me. I changed these two lines:

#define X_MIN_PIN                             -1
#define SPINDLE_LASER_PWM_PIN                 10  // Hardware PWM

I’m not sure why you were getting the timer/counter error message.

Thank you both for your help.
@robertbu That is what I changed yesterday. I don’t know why it wouldn’t work either.

@vicious1 It worked!!!
