Hi,
    Thanks very much for the interest in my issues and your comments.
What a fantastic medium this forum is when some one in the UK can have a problem with their hobby and people from all round the world can chip in, offer support, and share their experience. What a small world.
Many thanks to all.

Hi Craig,
             I run a homemade cnc lathe off the same control box and so I have to swap all the leads and plugs about when I run that and plug them in to all sorts of extension leads etc. This problem occurred after I had just used the lathe and had plugged every thing back in to use the router.  This morning I took all the plugs out and made doubly sure that the VFD was definitely plugged into a totally different socket.  Hey presto, it has been working fine for 30 minutes.  As you rightly say, some sort of interference issue but I am just grateful that at least the VFD & motor appear not to be damaged.  Hopefully it will continue to run ok
Many thanks for your time and advice.
Jacko

Hi Craig,
            Thanks for the reply. I haven't made any changes to the machine. I now  remember that I have had the problem for a while as this has happened before, albeit to a lessor degree. I managed to get away with it by plugging in the VFD in a plug socket, on its own,  a fair distance away. This seemed to cure the problem but I have noticed recently that the machine was sometimes not repeating a tool path. Now I think that there may have been an occasional "twitch" whilst working that I hadn't noticed causing the machine to "jump" This problem just seems to have gradually got worse. I did notice that it was far worse when building up to speed.  When it reached the required speed it hardly "twitched" I might just try plugging it into a completely different circuit in the morning to see if that has any effect.  I also think that I need an electrician!! You wouldn't just like to "pop" in tomorrow would you?
Many thanks
Jacko

Mach4 General Discussion / Huanyang VFD problems?
« on: January 27, 2017, 01:21:38 PM »
Can any one help with this please. I have had the VFD, which drives a 1.5kw spindle , for a year or so but when I start the spindle up now all the stepper motors start "twitching" and they can  move the spindle quite a long way. This even happens without mach being  loaded.  I assume the VFD is faulty unless there is something I'm missing. Anyone experienced this? Any suggestions?
Thanks
Jacko

hi,
 I attached the xml file but cant see that post on the forum.  I had previously attached some jpegs aswell which although it said that they had been sent i cant see them anywhere.  It previews ok and gives a message that it has been sent but cant see them anywhere. Have you seen them? - dont know  what i'm doing wrong if you cant see them anywhere.

Sorry for the confusion.  Untill today I had no trouble and could run the script which i had loaded a few days ago.  This morning the PC starts ok but just wont start Mach 3. The opening mach 3 screen screen appears briefly then  the afore mentioned dialogue box appears over the top and wont go away.  When i press ( ok ) or the close ( x ) button on the dialogue box nothing happens.  When I Control alt delete it tells me that mach 3 is running though.  And so in answer to your question it is to help me get mach 3 running  again please, if poss.  I had just assumed that it was something to do with the new script that I had put in, as it has never happened before.

I have been trying to attach stuff but  that doesn't seem to be working, However this is a link                 http://www.instructables.com/id/Mach3-Zero-Probe-Tool/ for the script.   i typed it in manually !!!   It sort of worked ok but I think the pin / wiring is stopping it working 100%
