#Using grbl controller with raspberry pi upgrade#

LightObject has a few ready-made upgrade kits with different models of DSP with different levels of capability. A lot of the DSPs on the market are ethernet capable, so you can have your machine running LaserCAD, LaserCut, or RDWorks away from your laser, and send jobs to it via network, or on USB keys.

Replace the controller with a Chinese DSP: This option is probably the most expensive, but the most 'plug and play' - You'll install a controller that makes your laser more or less a standalone unit.

Ripping out and replacing the guts isn't very difficult from a mechanical standpoint, as these machines, by and large, aren't complicated to work with. If you want to use alternative software, your only option is to replace the brains of your cutter.

To Digital Outputs, I2C/SPI, Spindle Control, CNC Control: BB1.There isn't unfortunately anything aside from MoshiDraw and the relevant Corel Draw plugins that will talk to the control board in your laser.

I2C and SPI Controls for expansion (via M-Code controls).

Custom Acceleration Scaling (custom M-Code control: M100), allow in-code changes in the acceleration parameter for each axis individually.

One application is driving PPM devices such as RC Servo motors (M-Code control: M67)

Eight (8) Digital Inputs (wait for input M-Code control: M66).

Eight (8) AUX TTL outputs (M-Code control: M62, M63).Separate input pins for positive and negative travel limit switches for each axis, allowing the use of active high optical photo-interrupters (typical GRBL systems have both limit switches on one input pin).Running at 921600 baud-rate (115200 firmware available). Multiple connectivity options: USB (onboard CH340), External UART, WiFi (ESP-01), or Raspberry Pi Zero W (WiFi).Default is 10KHz PWM at better than 14-bit resolution : 24000 steps in the 0 to 5V range. 240MHz timer for flexible PWM output control (Spindle or Laser).Smoother Acceleration/Deceleration (0.2 ms accel/decel step).Up to 550KHz pulse rate for each axis while under 6-axis coordinated motion, 750KHz max pulse rate when running 3-axis or less (more than an order of magnitude from 30KHz for Arduino based GRBL).With CAT-7, cable length of up to 10 meters has been tested. CAT-7 is recommended for longer cable run. CAT-5 and CAT-6 cables can be used where the shield connection is not required. Wiring through flexing cable carriers (chain) is simpler with industry standard flat CAT-7 cables. Connections for each axis go through one RJ-45, featuring 9-pins (including shield) allowing more flexible setup for larger systems with longer cable runs. The hardware design for the F46 features 12 RJ-45 вЂњethernetвЂќ connectors for connection to all peripherals.

With a 32-bit Arm Cortex-M4 core overclocked to 240MHz, the STM32F407VET6 (192kB RAM, 512kB flash) brings professional grade CNC control to the world of GRBL. The GRBе…ѓ2 firmware is a fork from GRBL version 1.1f, running on the 32-bit STM32F407VET6. The F46 is running GRBе…ѓ2 (an upgrade from the popular GRBL firmware running on an Arduino 328p processor).

With the faster pulse rate, more advanced stepper drivers can be used (featuring up to 256 micro-steps/full-step) without sacrificing feed rate. Applications include CNC, Pick-and-Place, and Robotics. Additional controls are available via I2C and SPI. Advanced features include: high pulse rate (550+ KHz), additional PWM (8X), digital inputs (8X), and digital outputs (8X).

The F46 is well suited for complex CNC or Robotics where motion control requires more than 3 coordinated axis of motion.
