The Lasers adopted for FABOOL Laser Mini are following 2 types;
- 1.6W diode laser 450nm (PL TB450B) from OSRAM Inc.
- 3.5W diode laser 445nm (NDB7K75) from NICHIA CORPORATION
Laser diodes are constantly kept cool by Heat Sink and Fan to prevent increase in temperature. Also a cover is installed to block the light from laser.
<Axis>
Fabool Laser Mini employs V-Slot Linear Rail(20 x 20mm) and Delrin Mini V Wheel from OpenBuilds for its axis. Thanks to the V-Slot, the number of parts decrease and makes the structure simple. Plus, the expansion of axis makes the processing area broader. The standard size of processing area is 300x230mm.
<Control Panel>
We adopted STM32F205 microcomputer from STMicroelectronics Inc. as main CPU for the Control Panel of Fabool Laser CO2/DS. PC and STM32 are connected with USB and communicate G code in serial communication system.
Except for microcomputer, the lasers are equipped with 2 A4982 drivers from MicroSystems Inc. and MCP4461 digital potentiometer from Microchip Technology Inc. for setting up the power for driver. MCP4461 is set by G code in I2C connection via microcomputer. The output of the laser is controlled by STM32, and the power is adjusted by PWM.
Kicad from open-source PCB CAD software is utilized for the Control Panel development.
<Firmware>
Open Source Laser Engraver Software Machine
The firmware for Fabool Laser Mini is developed based on GRBL(http://bengler.no/grbl). We implemented following function on the firmware.
- Laser Carving
- Power Adjustment for Motor Driver
- Switching ON/OFF of Laser Output
We adopted Eclipse and OpenOCD for the firmware development.
<Software>
Fabool Desktop, the software for Fabool Laser Mini processing, operate on Windows and Max OS X. The software imports SVG, DXF and other image datas and control processing by sending G code to the Control Panel of Fabool Laser Mini. SVG and DXF are processed along the outward form (vector processing), and image data is processed by horizontally scanning like as the whole data is filled and plastered ( raster processing ).
The programming language is C++, and the library is Qt5. The development environment is Qt Creator.
If you bought or going to develop a laser engraver with Arduino boards and GRBL firmware, here is a small but important configuration that significantly affects your laser process results.
GRBL is an open-source firmware that runs on an Arduino for converting g-code commands to the motion control of CNC machines. The controller was primarily developed for CNC milling, controlling the spindle rpm, which is known as spindle mode. The laser process has almost the same control loop, except for the tweak of laser power. Therefore, laser mode has been introduced in GRBL v0.9 or higher. You need to correctly configure the GRBL settings when installing the firmware to your machines.
What is the difference between laser and spindlemode in GRBL?
The planner moves the laser point to your defined coordination and tuning the PWM power of your laser diode in both laser and spindle modes. So, what is the principle behind that makes them result differently?
The main difference between them is how the spindle/laser output is controlled with motions. In the spindle mode, every time a spindle state (such as M3, M4, or M5) or spindle speed (Sxxx) is altered, the controller temporarily stops the feed motion. This gives time to allow the spindle to speed up/down. However, if it is used to control a laser, the staying leads to scorching, uneven cutting depth, or bumpy engraving marks! The laser mode prevents unnecessary stops whenever possible and adds a new dynamic laser power mode that automatically scales power based on the programmed speed along the path. So, everything is nice and smooth with the laser mode in GRBL. The detail of GRBL V1.1 laser mode can be found from GRBL v1.1 Laser Mode · gnea/grbl Wiki.
Enable laser mode in GRBL
Assuming you know about how to send a command to your machine with a GRBL sender, enabling/disabling the GRBL Laser Mode is super easy. You just need to change the value of the profile $32 in the GRBL setting.
- To Enable: Send GRBL a
$32=1command - To Disable: Send GRBL a
$32=0command
Upgrade to GRBL v1.1
There are two major reasons for the firmware upgrade. The first interest is to enable speed and power overrides in real-time during the laser process. The override function is a new feature of GRBL v1.1 while GRBL v0.9 does not.
The second important consideration is to enable the safety door setting for the emergency cutoff of laser power. The laser source does not power off while the step motors for the XY movement are de-energized in the HOLD mode of GRBL v0.9. A stationary laser point can cause serious safety issues, including laser and fire hazards. Upgrading to the latest firmware enhances the safety of the system. Crysis 2 working serial key.
