    This sound familiar was same here but in an other sequence and other controller NVEM v2 4 axis instead of NVUM.
    I had your second problem first after 1 day of playing, I noticed the communication led (green Ethernet) on the NVEM blinked much
    slower as when working. Contacted the seller with a movie attached and received a new one but had to wait 5 weeks
    as nomore available from the EU warehouse.
    The second NVEM works like a "charm".
    Meanwile I purchased a spindle
    Aircooled 2,2 Kw 3phase 300Hz 18000rpm collet ER25 (didn't find ER25 400hz 24000rpm as aircoolled and ER25 was main goal, was not easy/cheap to find in this setup)
    Huanyang 2,2 Kw inverter mono phase 220V
    The spindle is controlable from Mach 3 with M3 and M5 commands without external relay as mentioned befor,
    just have to check if rpm is displayed correctly with external hand rpm unit

    Grammatical errors are for free as google translate was helpfull

    I had the connection issue too and wasn't able to fix it. I asked the seller to send another one...
    This board are really lame. The second one worked 10 minuts and gave me the bin file error.
    Do you have the bin file or now how it is called. I've looked trough the internet but I only found borken links.
    Please if you have the bin file send it to me!!! It is the last try I give to this board.

    Re: Help with Novusun NVEM control card

    Hi all
    not sure this is the correct place for this post
    My first time on this forum and can not see where to start a new thread
    I have NVEM ethernet controller, having problems setting up the spindle
    It is a DC motor type, so all I need to do is switch a opto isilated relay to turn it on.
    Can any give some advise on how this is done and maybe a wiring diagram.
    I have every thing elses working OK this is the last thing to get going

    Befor I got the vfd and spindle I used a fixed speed AC router, I switched the router by a 24V auxiliary relay board from Aliexpress as I operate the NVEM at 24Volt
    https://www.aliexpress.com/item/4001...27424c4don1PpV
    It can be done easier but I like to have it safe as the NVE(U)M is a delicate board to mess up.

    NVEM S-axis

    GND connect -24V from power supply and also to DC minus on relayboard
    VSO connect to +24V from power supply
    Index not connected
    Out 1 connected to IN on relay board
    Out 2 was not connected as no need to rotated CCW

    Mach 3
    Setup in config Spindle setup
    M3 for CW output 1
    If use of CCW M4 output 2

    Output signals
    Out 1 port 2 Pin1
    Out 2 port 2 Pin2

    You can also use other outputs but need VB to write macro
    for activation as no buttons available in Mach 3 fot those outputs

    Hope this could help but all connections at your own risk.
    All these info here I found on the net but took me some time
    to have it work properly.

    Re: Help with Novusun NVEM control card

    hi guys I have original nvem bin, and novosun flash tool, can share it, send me an email 540lab -at- inbox-ru
    But I have to say, that I killed my NVEM with attempts of fixing bin problem. It was working fine out of the box, apart outputs, and when I needed them I decided to load EC500.dll plugin as written before by DigitalDream stupid developer, and immidiatly had a bin-file problem.
    Throwed nvem to real bin and ordered SmoothStepper (ESS), so wish you the same. I only sorrow about nvmpg, it wasn't that bad, hope to connect it to SmoothStepper.

    thank you,
    Bin the piece of garbage and buy something else that has ACTUAL existing support.
    ESS or UC400eth or something like that.

    The Nvum Boards work fine and are just as good as anything else in the price range, if you mess with programing the Board then this can happen to any Board that is programmable

    Try it with the ESS or any of the UCCNC products and the same thing will happen

    Re: Help with Novusun NVEM control card

    I have been using one if these for a while. Shame the dev doesn't fix the issues.
    I got most working. But 2 things won't.
    Backlash basically won't work. It will apply almost infinite acceleration so end up skipping steps. That's because mach3 uses the acceleration time for the mpg for backlash. Which is an odd thing to do anyway.
    So the mpg contole and backlash all have instant responses. And the timer setting does nothing on nvem v2.

    The other thing I can't get to work at all is the spindel index. I can get the hall effect to work on other inputs but these won't register it spinning. The index input I have tried everything and just can't make it trigger.

    No idea what else to do with it now. I have an old PC with parallel and may just go to linux cnc. Getting a mpg connected is the bit that worries me with that however.

    Has anyone got a spindle index to work out of this board?
