The next change is to add the new M666 line before each first feed move to set the power level. I thought an Arduino would be a good choice because it has a built in USB to serial port, it is less cheap (less than $20) and it is open source. There are a lot of commercial Modbus devices like ModIO and the Automation Direct PLCs, but I wanted a cheaper home grown version. The devices typically communicate using a serial port or Ethernet. The remote device can then use the data registers to give information to the host or do a task when a register is written to by the host. Modbus devices are basically remote device that allow a host to read and write data registers. I thought it would be a fun experiment to try to enhance the control using a Modbus slave device. The normal spindle logic does not work well with lasers. It must only be on during G1 feed moves and must not dwell at any point or excessive burning will occur. A laser cannot do that because it does not retract from the material. On a mill, the spindle can safely stay on during rapid moves above the work and dwell at points without issue. It does the cutting and has an on/off state and power level (like RPM). The beam can be compared to the spindle of a mill. This is especially true when it comes to the beam control. People have used it to control a vast diversity of machine, but it has some issues when controlling lasers. Output port P1 port Open all 17 ports, which can be accessed with the optocoupler drive, 5-axis stepper motor can be controlled.Mach3 is a great program. Featured by Sharvi Electronics All the way through the optocoupler isolated 0-10V analog voltage output can be controlled with the corresponding analog interface converter to control the spindle speed. With this 5 axis breakout board, any 1-5 single-axis stepper driver controllers can be directly controlled by the PC via the MACH3, EMC2, KCAM4, etcĪll the way to the relay output port, control spindle switch.
