1 CNC Milling Engraving machine G4030A Instruction manual

2 1. Safety notes Every machine controlled by computer (PC) can be really dangerous for human life and health. Comply with bolow rules and use Your common sense while working with the machine: NEVER do any additional jobs while the power is connected to the machine (like material clamping). If You are clamping the material, check if the E-Stop button is pressed (machine locked) NEVER put Your hands close to the moving parts of the machine. There is a risk of accident and/or machine damage ALWAYS make safe the place of using the machine and keep children and unauthorized personel away from the machine. It is not a toy! ALWAYS work only with efficient machine, use only efficient tools. ALWAYS use safe holders/clamping tools for holding the material. For this purpose use only intended equipment TRY to use simulation software, to prevent possible collisions of tool with holding elements. If simulation software is not available, try to run Your new G-Code with minimal speeds. ALWAYS connect Your machine to efficient electric net, which MUST has safety wire. USE personal safety equipment: safety glasses and equipment lowering the noise. NEVER use gloves! 2. Machine s general purpose Milling Engraving machine G4030A is designed to engraving, milling and cutting parts from materials like wood, plastics, engraving laminates, plexi, light metals (aluminium, brass, bronze, silver, gold). Because of using hight speed spindle, there is no possibility for hard metals milling (except hard metals engraving). Machine can work in 2,5D and full 3D mode. This manual will not cover the machining knowledge itself. 3.

3 4. Mach3 configuration In the below table You can find configuration datas for Mach3 s Ports&Pins setup. While configuring the software just use the corresponding pin and port number. Pin Function Port 1 Port 2 1 Out A Step A Dir X Step X Step - 5 X Dir X Dir - 6 Y Step Y Step - 7 Y Dir Y Dir - 8 Z Step Z Step - 9 Z Dir Z Dir - 10 INPUT 1 servo error X++ 11 INPUT 3 Y Home, Y++ E-Stop 12 INPUT 2 X Home, X++ Y++ 13 INPUT 4 Z Home, Z Relay 1 Spindle - 15 INPUT Relay 2 Flood - 17 Out 4 (ChargePump) active with 12,5kHz active with 12,5kHz LPT GND Description in the table presents LPT side port pinout. Pinout for machine inputs (Centronics36 pin connectors) is corresponding to standard parallel printer cable. Signals description: Step step signal for one axis drive Dir dir signal for one axis drive Input 1-4 inputs for e.g. limit switches Relay relay output ChargePump this is the function of Mach3, which allows to use/move machine only if the software is running correctly. On the input of ChargePump there must be correct signal, with proper frequency, generated from Mach3 (12,5kHz). All two mainboards, built in the machine control box, need this signal to be active. Servo Error used for servo error output/input from servodrives. This output is connected directly to Mach3 s input (throught optoisolator), and stops Mach3 when in any drive an error occured. (needs additional brain for Mach3). 5. CNC Programs (G-Code) This manual will not cover G-Code description and generation. 6. Postprocessors

4 If You have any CAM software, You can get some posts from Mach3 developers site Working with machine 7.1 E-Stop safety button E-Stop button located on the front of the machine is NOT SOFTWARE DEPENDENT. Pressing it You are cutting the servomotors power supply. It is second safety, because the machine will not run without ChargePump signal generated in Mach3. After pressing E-Stop button it is recommended to do re-referencing machine s zero point. To un-press this button, turn it in CW direction. 7.2 Turning on power To turn on the power, set the main power switch located on the electronics box (at the rear side) to position 1. Caution! Turn power On, only if the machine s E-Stop switch is pressed (machine locked)! 7.3 Machine s zero point routine After power is switched on, the operating system is loaded (and so Mach3), its time to set the machine s zero point. Doing this, the machine will know where the zero point is located and will allow to use material s offsets (G54, G55 and so on) and tool length sesor. To set machine s zero point go to Tooling menu and press REFER All Home button on the touch screen. 7.4 Material s offset (material s zero point) Most of machining strategy works with relative material s zero point. Offset is difference between machine s zero point and material zero point. To set offset, choose one offset from Tooling -> WorkSpace and press needed work offset. To set axis offset touch the field next to the axis (in Active Work Offset frame) and type 0 from screen keyboard and press Enter. Do the same with other axies if needed. To physically set the axis to material offset, use Jog Wheel (control panel) or go to Setup -> Jog Menu and use screen arrows. 7.5 Running/Stopping spindle rotation The machine is equipped with automatic running/stopping spindle function. Caution! Be extremly carefull when changing tool in the spindle collet. Running the spindle manually is possible by pressing button Spindle on the control panel s front. Pressing this button second time will stop the spindle. Spindle has set some delay to give it time to reach its nominal rpm (depends of spindle type). Running the spindle automatically is possible by command M3 and M4. Normally M4 command is moving spindle in CCW direction, but some spindles are not left-rotational, so both M3 and M4 are running the spindle in CW direction in this case. To stop the spindle use M5 command. Both from inside of G-code and from MDI line spindle can be controlled. 7.6 Switching Flood/Oil fog function On and Off Machine is equipped with automatic cooling system (air or oil fog). To use oil fog check the oil in the container at the rear of the machine. Set oil dose with valve. As cooling factor You can use oil etc. Do not use water and water based factors (corrosion). You can also set air flow, by turning the screw located on the air filter. Air cooling can be switched on similarly as spindle operation. Pressing Flood button on the control panel will swich flood on, second press will switch flood off.

5 Automatic switching Flood works by using M8 command. Turning Flood off by command M9. 8. Turning power Off (machine) To turn off the machine set the main power switch to 0 position. Make sure, that the operating system was closed properly. To do this go to screen Main menu and then press Shut down button (press Accept when asked about shutting down system). 9. Maintenance Maintenance jobs are mainly greasing of working parts (linear slides etc). If the machine is not used for longer time, it is need for protection against the corrosion. You should protect ballscrews, work table, etc. You can use popular greasing fluid like WD40 or similiar. For more informations contact us at: info@cncdrive.com Found a bug in this manual?
