Paste your configuration file to the SD card.Optical door alarm You should : Format your SD card ( as FAT32 ) Paste the most recent firmware file on your SD card. Sometimes SD cards get corrupted, and it can cause all sorts of weird and difficult to understand problems. Because of a change in the pin-out in grbl version 1.1 (pin 11 and 12 are swapped), the spindle-pwm signal can be found on the Z+ pin. The CNC shield V3 for Arduino Uno was designed for grbl 0.9.

The following information refers to cheap (counterfeit?) boards that are available on ebay for 12€ to 15€ (including shield, arduino, A4988 drivers and USB cable).

Note: internally the PWM range goes from 7 (0.5 ms pulse width) to 38 (2.5 ms pulse width), which results to 32 possible different servo positions (probably less, because the regular range is from 1 ms to 2 ms). The pulse width range is 0.5 - 2.5ms." (Duty cycle it then from 3% to 15%). If a different frequency is required, this may be altered by editing the cpu_map.h file."Īdapted grbl: "This is a special version with servo support (swichable in config.h) The PWM frequency is set to 61Hz (prescaler 1/1024). Regular grbl: "By default, the spindle PWM frequency is 1kHz, which is the recommended PWM frequency for most current Grbl-compatible lasers system. The duty cycle is then just in the range of 5% to 10% - not suitable to control a spindle or laser.

By default, the PWM frequency is set to 1 kHz.This means the pin for the output of the PWM cannot be changed. The pulse width modulation (PWM) for speed control of a motor or power control of a laser, is generated via a special pin function (hardware PWM) inside the ATmega328 (the microcontroller of the Arduino Uno / nano) on pin 11 (PB3, OC2A). More information here: quick-guide-to-setting-up-your-machine-for-the-first-time The product of $10x and $11x must stay below 1800000 to avoid pin frequencies above 30 kHz.Į.g. Note: a too large number for $10x (steps/mm) and $11x (max. The main settings are $3, $10x, $11x (x=0,1 or 2 depending on axis) to get the stepper motors running in the correct direction. The screenshoot shows the initial settings after the installation of grbl. Check the grbl-Wiki for more information. Now the buttons inside the GUI are enabled and the stepper motors can be controlled.Īfter pressing "$$", grbl lists the stepper motor settings, which must be adapted for each machine. After successful connection, grbl sends a start-up message "Grbl 1.1h ". Start GRBL-Plotter and select the correct COM-port for the controller.
