The VFD is capable of spinning the motor in reverse but as supplied the CNC controller had not provided that capability i.e. The second output is an analog control voltage and is used to control the speed. One is a simple digital (on/off) signal that is connected to the VFD Fwd input. The breakout board outputs two signals to the VFD. Pin 17 turns a motor relay on and off and pin 1 has a pulse width modulated (PWM) signal used to control the spindle speed. From the information I had to hand there are two signals from the PC that are used to control the spindle. This is the area that was hardest to nut out. It seemed much improved over the default values without missing steps during movement. This was something I didnвЂ™t spend much time experimenting with. Other motor settings I played with were the maximum travel rate, 1200mm/min for X and Y, 400mm/min for Z and the max acceleration of 8mm/s^2.

The pulse/mm setting is dependent on 3 things, the stepper motor (200 steps/rev), the ball screw (4mm/rev) and the drivers micro step setting (x8). A little fiddling with the motor config and a ruler determined that there were 400 pulses to the mm. Once these were entered I was able to move the machine around. From memory this was on pin 14 and was active low (I am no longer at my uncles place). Changing the input to active low fixed the problem and I could happily push the E-Stop and see the Emergency indicator light in the diagnostics panel. I immediately got a warning about an external condition.

A bit of trial and error identified the signal coming in on pin 10. I decided to track down the emergency stop input by using the diagnostics screen and the ports and pins config page. The next stage was to connect the parallel cable and power up the controller.

With the parallel port driver installed and the newer Mach3 configured I was able to get the multimeter needle to move.

During installation of the latest version I encountered my first bit of luck, the system asked me if I wanted to install a parallel port driver. The current version is 3.043, a little more up to date than the version I had disks for. After some minor reconfiguration and testing I was still unable to get Mach3 to toggle the parallel port pins.ДЄt this point I took another look at the Mach3 downloads page. It needs to be the 32-bit version so an operating system downgrade was performed and Mach3 v2.58 re-installed. According to the Mach3 requirements page this wonвЂ™t work. According to the mill documentation pin 14 was meant to be an ENABLE signal but clicking the RESET button in mach3 made no difference to the voltage level on the pin. Poking around the PCвЂ™s parallel port with a multimeter I was able to measure 3.3 volts on many of the outputs, pins 1-9, with the ground connected to pin 25. After taking off the cover I found a TX14175 parallel breakout board (BOB) and four stepper motor drivers, model TX14207. It connects to the PC via a parallel cable. The CNC controller is generic Chinese, the beige one with a sloping front panel, variable frequency drive (VFD) controller, 4 channels (X, Y, Z and A) plus an emergency stop. No amount of jogging or config change would make it step. It had been supplied with Mach3 v2.58 but whilst the software installed ok and the controller powered up, the only thing it would do is power the stepper motors and вЂholdвЂ™. Unfortunately he hadnвЂ™t been able to get it going and it had been sitting idle. Some time ago he had purchased a Chinese 6040 CNC mill on eBay: This trip was a little different, this time I was able to make a contribution to one of his projects.

This trip was no different, me being led on the obligatory workshop tour as my uncle filled me in on the status of his various car restorations, instrument making projects and machine tool acquisitions. My uncle is a mechanical genius and a visit to their property is always enjoyable. This week I spent some time with my aunt and uncle.
