This requires both a variable speed motor and a matching speed controller for it. ģ Introduction One very nice feature to have on your CNC machine is the ability to control the spindle speed from your CNC control program (Mach 3). Conventions used Indicates a note for parallel port users. Nothing can ruin your day faster than having a piece of metal being hurled at you by your machine tool. Secure all stock to prevent it from becoming a projectile during machining.

However, it is best to also have a manual interlock switch in-line with your spindle motor to ensure that the spindle cannot accidently be turned on when you are changing bits. Safety Tips Some controls like the STDR-4C will automatically power the spindle when commanded to by your controller (Mach 3). We strongly suggest that you avail yourself of all the information available for the components you re putting into your CNC system and understand how they will all interact. In reality the only person who can keep you safe is you. While we make every effort to provide in depth and accurate technical information we cannot make any guarantees about their applicability to your particular application. The laser power is controlled by Pules Width Modulation, PWM, which is generated by the ESS this is switched on and off by a gate.1 Soigeneris AN-01 Using the G540 VFD Output V.3Ģ A word about safety We at Soigeneris take pride in providing high quality components for small scale CNC systems. To help others to get their laser connected to an ESS and Mach4 here is a bit of a guide. Recently Andy from Warp9 has incorporated some macro codes in the ESS to manage both vector and raster laser burning which has taken some of the processing load off Mach4. Around this time I purchased an Endurance Laser 10 watt+ and with the help from SmoothStepper and Endurance community got it going on my machine. I then discovered the Wrap9, the SmoothStepper developer, was working on improvements for controlling lasers. Then I found that Mach4 had M63Px and M63Px designed especially for lasers, these turned the laser only when there was movement and off when movement stopped so I moved to Mach4 for my laser. Because of this delay, I started using M11Px and M10Px to turn the laser on and off and this was working fine. One of the very early lessons was that there is a delay with the laser coming on after an axis move and going off once the movement has stopped when using M3 and M5 to control the laser. My initial laser was a 3.8 watt from Jtech which helped me learn about laser control. This uses a SmoothStepper to control the movement of the axis and run under Mach3. I started with a CNC Router Parts, now Avid CNC, Pro4896 router kit I built a few years ago.
