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.
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.
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.
