I have had the lube pump housing apart and can see nothing that looks out of the ordinary. I have disconnected the pump motor from the cover and again tried to M3 but the same thing occurs. Just thinking out loud - is that to be expected as there is nothing connected to the wires or is the issue wit...

Thanks for your help so far. I have had a look at what could be causing the shorting out of the SGR SRR and through a bit of trial an error I have narrowed it down to wire 31 that comes out of the SGR. Without this connected the machine will connect with VR Milling and on M3 (Spindle Forward) wires ...

I tried removing the spindle drive supply fuse (F1) with no joy. I did notice though that when measuring the voltage the drop occurred across the ESR along with the SGR and GIR not sure if this is significant?

Has the machine been moved? Yes it has and hasn't worked since it has been re-sited. Check the pins in the harting plug on the connector on the back of the machine. I have checked what I think is the harting plug (the large interconnect between the rack/power supply and the Triac) and have reseated...

Thanks for your suggestions. I guess there is an issue with the stepper motors not receiving any power hence being unable to home. there are 3 fuses located on the rack base plate, just to the left of the orange stepper connectors I have checked the three fuses as suggested by blatter and all three ...

When it's powered on,estop is out and you're connected to VR milling, you will not be able to spin the stepper motors by hand. I have just checked the stepper motors and they can be spun when the machine is powered, the e stop button is not active and the machine is connected to VR Milling. I guess...

Thanks for the really prompt reply. I have removed the stepper motor from the x axis and have been able to rotate screw on that axis without a problem. I have tried the z axis but as you say I think that has a brake applied. The motor doesn't get hot as such but when I rotate the spindle on the moto...

Many thanks for the responses. I didn't realise that receiving emails up responses was unchecked by default! Denford Admin - how do I go about checking that the drives are powered up? I have tried pressing the Axis Limit Switch whilst trying to home the machine without success. I have also checked t...

Problem with Denford Triac PC circa 2001no ATC. We are currently having a problem whereby the PC connects to the triac but is unable to get a response to home all. We are using VR Milling 2.25.3.917 via an RS232 cable. When trying to home the machine the co-ordinates on screen move as normal but the...
