Help with Novusun NVEM control card

[juninho-jesus]

Some issues found in my board:

- Homing / Limits -> The NVEM v2 controller can home two axis, the third axis get a "limit trigger" error. (Configured like the manual, just the positive limit trigger "X++; Y++; Z++;")
- Spindle -> Mine NVEM v2 cannot set the right speed in Spindle, I checked the VSO output, I was getting 10.37V in 24k RPM. When i set 15k RPM in Mach3, I get 14.1k RPM in the Spindle.
- Spindle 02 -> Very very slow ramp up. About 30 sec to get from 0V to 10V.
- Probing -> Just Impossible to probe with this board, it's even difficult to explain how the probe is erratic.
- SoftLimits -> don't work as well.

Was a little difficult to configure in Mach, but you have to "allow the program to get internet connection" it's a setting in Windows Firewall. Configure the IP Address correctly and boom, it works.

But these issues above get us crazy.

Plugins tested:
NVEM v2 is original, with "Lollete" stick.
https://www.nvcnc.net/pdf/Novusun.rar -> Downloaded here.
https://www.nvcnc.net/pdf/EC500-DLL_V1.rar -> Downloaded here (Told by DigitalDream that plugins works because EC500 is a updated of NVEM)

Hello, I am thinking of using a DC Motor Spindle. I want to use NVBDL+ as the Spindle Driver and NVEM as the CNC Breakout Board.
I want to control the Spindle Speed with PWM.

What is the appropriate connection between NVBDL+ and NVEM?

[punsg1]

Pls see the attaching file.
it is the DLL file, if you use the dll file pls follow the configuration of EC500.
Because EC500 is updated from NVEM V2,they can share the same dll file.

Welcome more questions.

i have problem with output port
what should I check ?

[miky4u2]

I haven't been able to follow this thread for quite a while but I see an EC500 came out and a DigitalDream developer suggested to use the EC500 driver on the NVEM V2...
My question is , is there anybody out there who has been able to use Soft Limits/slow zones and Slave Axis with either the NVEM V1, V2 or EC500 , or are they still selling those boards with un-fixed drivers ?
Have they even fixed the 'Limits Override' problem at all ?

Cheers
Miky

Buy this cnc controller: https://www.amazon.es/gp/product/B07...?ie=UTF8&psc=1.
I can't get the axis movement to work with the keyboard or with the mach 3 MPG module.
if I remove the Novusun.dll plugin it works, but the controller does not communicate with mach 3.

if you are connecting directly to the computer you need to change the network adapter on the computer to static IP 192.168.1.11

I still can’t get mine to connect.

Hi. Just received NVEM version 2 for 3 to 6 axis bought from Aliexpress. The shipping cardboard box was damaged and there is a big scratch on the CD and my PC just won't read the disk at all. I posted to the seller for the files but they do not reply. Is there a friendy person here who could post or have a download link to the latest NVEM Mach3 Ethernet driver and what ever other stuff there is on the CD? I have a commercial Mach3 so what I really need are the driver and manuals.

PS. I made a dispute to Aliexpress and they gave me tree days to reply and decide whether I take a $20 refund or ship the whole thing back for full refund. Shipping it back to China form Finland would cost 44€, so which ever choice I make it would be a bad deal if I can't find the driver and get the thing working. My first Aliexpress purchase, not a very promising start there.


Thanks,

Found the recommended EC500 driver and EVEM V2 manual from the manufacturers site https://www.nvcnc.net. I'm exited to see if this thing will be good enough in the end to replace my two parallel ports and two BOBs which limited the speeds of my servos.

So far Mach3 has accepted the driver and responds to Emergency input and Digitize inputs from EVEM inputs which I'm able to test on my drawing board with a Dell laptop. When starting I saw plenty of LAN traffic between PC and NVEM but no communication between Mach3 and EVEM and nothing worked. After completely disabling Firewall (for both Private and Public networks) communication started to work.

I have the NVEM V2s IP at 192.168.1.11 which is in the same IP address space my router uses so I wonder how that can work if the WIFI is enabled at the same time? (Can't test that as my Dell laptop automatically disables WIFI if LAN cable is plugged in.) Would like to hear about that if someone has the knowledge. Next step is to get things working on an old Win10 32bit PC for Mach3 and also get a new iHSV86 servo motor to run with EVEM.

Thanks churchile but I finally found the driver and manual.

Just a follow up for someone else struggling with these: Mach3 runs fine on Win10 32bit and NVEM seems to communicate fine too on wired LAN even with WIFI on at the same time. Will there be conflicts remains to be seen. As a plus with the 32bit Windows 10 2004 version I set up for this old PC with Athlon processor and 2G RAM, my age old Acad Lite 97 runs now fine on Win10 (!) and even Office 97 runs on it.

Hello
this problem happens to me:
I install mach3 and the profile for NVEM v2, copy the plugin in the folder and launch mach3 ....
I select the plugin to use and it tells me "Choose bin file"
but I don't have any bin file to load isn't it by chance that I have a broken installation cd ??
I am attaching a video of the problem, perhaps it does not find the correct firmware

HELP meeeeeeee !!!!

[Schifty1]

Hi Filusico,
To tell you the truth, I got fed up with trying to get the Novusun working. After about a month of trying all kinds of tricks, calling people, and getting no help from Novusun, I broke down and bought the UC400ETH (~$150). from CNC4PC.com. It works GREAT right out of the box, no issues what so ever. I used this breakout board with it. https://www.ebay.com/itm/5-Axis-CNC-...AAAOSwrFtaOM0E
everything working and the manual has all your Mach3 settings. I am using the CNC4PC software which works very well, and comes with the Ethernet controller, so no added expense there.
Bottom line, the faster you get rid of the Novusun, the quicker you will have a machine up and running.
Hope this helps.
Regards Schifty1

You can also get an AXBB-E for similar price as the NVUM, the difference is that the AXBB-E works.

I`m guessing you havent been checking to see what problems everyone has had with their NVEM controllers, seeing you havent answered any more questions. People should steer well away from anything you make, as you provide Sketchy diagrams at best, no proper info on port/pin configurations. None of your products work as advertised. I have checked my wiring on my MPG handwheel connected to my NVEM V1 so many times and I still cant get it to work. Half the links on your web page to drivers do not work, and yet you are still taking peoples money. How about proper support for the people who bought your original products??

[OlfCNC]

NVEM is a Chinese company and the producer of the AXBB-E and the UC400ETH is a European company.
They have no affiliation whatsoever, they are totally different companies on different continents.
The only difference between their products is that one works and the other doesn't .
My advice is the same, to stay away from NVEM, NVUM etc. controllers, they are Chinese junk.

Hi,

I have just gave up about NVEM Controllers and downgraded to Parallel Port (working FAR better than the novosun Controllers!), however just before i move one, i got some information and "tools" that can help those that want to keep working with Novosun.

On last days i have been talking with Shania, a after-sales support of dcnc.com, the manufacturer of these controllers, through sales@ddcnc.com. Very fast reply (same day or next one),
and i got these files:

-NVEM.bin
-NVUM.bin
-A Tool called NOVUSUN_GEN0728.exe, an executable that allow to connect diretly with a NVEM/NVUM Controller bypassing Mach3, showing some details about the current controller and allowing update bin files.
-3 New Plugins.

I really hope this can help who is struggling whith these controllers!!!

Last information is that DDCNC has discontinuated the NVEM/NVUM, being replaced by the UC300.
