I'm not sure if I like this as it doesn't seem to allow any ES on the spindle.
To prove this, I disconnected the direction signal and it still worked as it had before. By the way, in order to get this all to work I had connected the "run" contacts on the V3 directly together so stop / start seemed to be controlled only by the step function (?). but when I tried this it seemed to spin the spindle at increasing revs - moving up by approx 20% each time. Now, I'm not over familiar with Mach 3 yet so I wasn't too sure on spindle calibration etc. This time the spindle fired up when I clicked on the spindle toggle in Mach 3 - ah, sweet success ! Lots of fiddling later and I was getting nowhere so I moved the plug to the 1st LPT port (Gecko was not connected during any of this routine) and re-configured the signals and pins. Testing the V3 showed that there was virtually 0 volts on the analogue output and the relay was remaining open. After telling Mach that there was a 2nd port and assigning the spindle step and direction signals to the relevant pins on this port, I tried to get the spindle moving but, alas, nothing was happening. Now I soldered just three wires to a DB25 male plug (step, dir and gnd) and connected these to the V3 board, plugged it into the 2nd LPT port and started Mach 3.

This went into the computer easily and Windows XP recognized it as soon as I had installed the drivers.
#G540 enclosure install#
After a couple of hours of soldering (?) and generally making a hash of things I looked at it from a different angle and decided that it was easier to install a second PCI parallel port card that I had on hand.
The next suggestion was to make up a short DB 25 male to female lead and take the two required wires from this. Firstly I opened the case of the Gecko G540 to see if I could isolate the signals from pins 1 and 14 - no luck there - it's all pcb and direct connections. This set up requires two signals from the parallel port to be fed to the V3 board. On the advice of Angel Tech, I obtained a V3 board from Roy at DIYCNC and a small 12v PSU from ebay. This is a follow up to my initial post for the benefit of any one else that may be trying to do a similar thing. Any replies need to be in a fairly simple format for me to understand. I should point out that I am NOT an electronic type person - any such references to electronic terms in the above are only what I have noted down in my research. Is anyone able to tell me if I can use this board in my intended set up to control spindle speed and, if so, what connections must I make to the isolator board (i.e G540 0 - 10v output and any other power requirments) and on which connection points? The problem is that the input to this board is a multi way ribbon cable. Whilst disembowling the black box I have noted that the signal feed into the Sprint 400 appears to pass from the Smartstep 3 board through an isolator board that feeds out through red and blue wires. My problem is that the Gecko G540 is only opto isolated up to 110v (for the US market) but the Sprint 400 "floats" at 240v and cannot be connected directly from the G540. However, my initial query is to do with spindle control.Īfter removing all the innards of the "big black box" I have identified the Sprint 400 (?) spindle control board and have spoken to the manufacturer about it's connections.
#G540 enclosure how to#
I have much to do with setting up Mach 3 (and learning how to use it ) and I may have further queries on things like home switches etc. So far I have managed to hook up the original steppers and got things moving using an XBox 360 wired controller as well as through the screen / keyboard.
#G540 enclosure driver#
I am converting a Novamill to Mach 3 and I'm using a Gecko G540 driver with 48v 12 amp PSU from CNC4U. Hi, Just got registered on the Denford forum and I'm looking for some advice or help.
