    the arrows are showing table movement, and as we all know it's the tool movement we look at.

    Ah, yes, that makes sense. I am used to 3D printers and my own previous mill where the head moves, not the table.

    Can someone please explain this to me?

    Look at the image below, this is the wiring diagram and shows that the 24 PSU (down the bottom) is fed from 110V, correct?




    Then here is a photo of the same 24V PSU, take a note of the 'jumper' on the bottom right. What is this set to take as AC input voltage, 220 or 110V?



    So, if there is a jumper, its 110V, if not 220V?

    The way I read it is if you want to run the tx on 110V then leave the link in. leave the link out if you require it to be run on 240V.
    Have you measured the o/p voltage? ..Clive

    That's my understanding too. There is no jumper, therefore its set to 220V.

    I wired it directly last night as I wanted the CS Labs controller to stay powered, even when the 110V drops out for whatever reason. So I connected it to 220V and a bit later, the PSU greeted me with some smoke. I should have measured the voltage prior to connecting up but there is no jumper, I checked this, which means 220V input is OK.

    Clearly not .... Maybe both of us have the wrong way of thinking of this link / jumper. Just to confirm, that pic was taken before anything was changed and shows all wiring as it was. There is no jumper / bridge. I checked the unit again this morning before coming to work.

    There must be a jumper in there somewhere. Ill triple check tonight. If you look at the manual too, it confirms what we both believe to be correct. I see no jumper ....

    It's hard to tell due to the clear plastic cover, but I'd say there's a little metal bar going up and over the plastic divider between the terminals.

    Yes I was going to say put an ohm meter across the two terminals and see if it is in fact a dead short.

  9. #89
    Yep, will do that. All hindsight now, need a new PSU.

    Sorry wasn't ignoring you I went out last night.!
    Ok well looking at the manual the Motors use Resolvers rather than Encoders and the Drives simulate encoder output so resolution will depend on how the drives are set.
    The Ratio is simply if there are any pulleys or gearbox's involved. If not then ignore.

    Goto Homing and Limits and Click reversed.
