Re: Portable Appliance Testing (PAT Testing)

It should be noted that the Health & Safety Executive have recently issued guidance on PAT testing which basically syas that it's a waste of time. It is advising UK businesses to re-assess their PAt testing regime as millions of pounds are being spent unnecessarily. For once I applaud the HSE for th...

Re: Novamill spindle speed control from Gecko G540

After a lot of help from Angel Tech I've now got Mach 3 operating the Novamill's 3 axis and the spindle stop/start and speed. Eventually I had to break out three wires from the parallel cable to feed to the V3 board that, in turn, feeds the spindle control board. Whilst it's all working nicely, I'm ...

Re: Novamill spindle speed control from Gecko G540

Once again I thought that this was a basic error and things would be spinning soon - wrong! I had convinced myself that I had not set the 2nd port correctly so as soon as I got home I checked in windows device manager and, sure enough, it had allocated a different i/o range than Mach 3 had assumed. ...

Re: Novamill spindle speed control from Gecko G540

Hi AT, I'm not at home until Thursday so I can't check the computer 2nd port but I did wonder if I had completed it correctly. I've just checked on a copy of Mach 3 that I have on my laptop and I note that in the config ports and pins menu Mach has already assigned a port address for 2nd LPT, irresp...

Re: Novamill spindle speed control from Gecko G540

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. On the advice of Angel Tech, I obtained a V3 board from Roy at DIYCNC and a small 12v PSU from ebay. This set up requires two signals from the parallel port to be fed to the V3 board. Fir...

Re: Novamill spindle speed control from Gecko G540

Hi Angel tech, I've been following a number of your forum submissions and was hoping that you might pick up on my query. I've spent a couple of hours looking at the DIY CNC site and in particular the V3 board. I didn't think that the V4 was applicable. just as I thought I had got it sorted in my hea...

Novamill spindle speed control from Gecko G540

Hi, Just got registered on the Denford forum and I'm looking for some advice or help. I am converting a Novamill to Mach 3 and I'm using a Gecko G540 driver with 48v 12 amp PSU from CNC4U. So far I have managed to hook up the original steppers and got things moving using an XBox 360 wired controller...
