if this is too awful to read due to the text blocks please let me know and i can throw them into paste bins.
So, as it says in step 1 of section B here, https://www.v1engineering.com/wp-content/uploads/2016/01/MPCNC-laser-add-on-walk-through-Rev2.0.pdf
youre supposed to change the pin from d9 to pin 44. the pins_RAMPS_13.h file that the guide originally calls for no longer has any pinouts, so i went to where it was calling for the pins, pins_ramps.h and i changed the designated pin for the fan from
// Heaters / Fans
#define MOSFET_D_PIN -1
#define RAMPS_D8_PIN 8
#define RAMPS_D9_PIN 9
#define RAMPS_D10_PIN 10
replacing the 9 to a 44
this didn’t work when i tested it.
when i went back to look and further explore the file, i found
// M3/M4/M5 - Spindle/Laser Control
#if ENABLED(SPINDLE_LASER_ENABLE) && !PIN_EXISTS(SPINDLE_LASER_ENABLE)
#if !defined(NUM_SERVOS) || NUM_SERVOS == 0 // try to use servo connector first
#define SPINDLE_LASER_ENABLE_PIN 4 // Pin should have a pullup/pulldown!
#define SPINDLE_LASER_PWM_PIN 6 // MUST BE HARDWARE PWM
#define SPINDLE_DIR_PIN 5
#elif !(ENABLED(ULTRA_LCD) && ENABLED(NEWPANEL)
&& (ENABLED(PANEL_ONE) || ENABLED(VIKI2) || ENABLED(miniVIKI) || ENABLED(MINIPANEL) || ENABLED(REPRAPWORLD_KEYPAD))) // try to use AUX 2
#define SPINDLE_LASER_ENABLE_PIN 40 // Pin should have a pullup/pulldown!
#define SPINDLE_LASER_PWM_PIN 44 // MUST BE HARDWARE PWM
#define SPINDLE_DIR_PIN 65
do i no longer need to fuck with the pinout lists? seems like it is controlled here but i cant figure out exactly what its doing, and more importantly, which pins to use.
i looked in config.adv of the current marlin dualendstop firmware that ryan gives us, and i find
- Spindle & Laser control
- Add the M3, M4, and M5 commands to turn the spindle/laser on and off, and
- to set spindle speed, spindle direction, and laser power.
- SuperPid is a router/spindle speed controller used in the CNC milling community.
- Marlin can be used to turn the spindle on and off. It can also be used to set
- the spindle speed from 5,000 to 30,000 RPM.
- You’ll need to select a pin for the ON/OFF function and optionally choose a 0-5V
- hardware PWM pin for the speed control and a pin for the rotation direction.
- See http://marlinfw.org/docs/configuration/laser_spindle.html for more config details.
#define SPINDLE_LASER_ENABLE_INVERT false // set to “true” if the on/off function is reversed
#define SPINDLE_LASER_PWM true // set to true if your controller supports setting the speed/power
#define SPINDLE_LASER_PWM_INVERT true // set to “true” if the speed/power goes up when you want it to go slower
#define SPINDLE_LASER_POWERUP_DELAY 5000 // delay in milliseconds to allow the spindle/laser to come up to speed/power
#define SPINDLE_LASER_POWERDOWN_DELAY 5000 // delay in milliseconds to allow the spindle to stop
#define SPINDLE_DIR_CHANGE true // set to true if your spindle controller supports changing spindle direction
#define SPINDLE_INVERT_DIR false
#define SPINDLE_STOP_ON_DIR_CHANGE true // set to true if Marlin should stop the spindle before changing rotation direction
anyone have any luck?
