Hi,
Ethernet SmoothStepper (ESS) by Warp9TD, US made.
Craig
For every one who have the same problem with very slow rising and falling voltage on spindle control output.
You need to change one of the capacitors on NVEM board.
Originally selected capacitor (red circle) was 100µF 16V smd. I've changed it to 1µF 50V (electrolytic). I didn't measure how long it takes to reach 10V, but now is mater of 1-2 sec. or even less.
I recently became the owner of my second Novosun NVEM V2, the first lost Ethernet communication, received one new in warranty.
What a nightmare to find out the ports. I like to share my findings.
For some strange reason I had after a while to reinstall the bin file, WHY? (found the appropriate on the Lolette site www.https://www.nvcnc.net/nvem.html)
Input ports are all on port 1
E-Stop,Probe, all endstops where also activate
Output ports all on port 2 and negative
Managed to activate all 10 outputs, for all outputs above 4 you need VB programming to activate.
out 1 = CW
out 2= CCW
out 3= mist or flood
out 4= flood or mist (don't remember)
I will now swap the USBCNC to the NVEM on the machine
Don't have to connect a VFD as I use a normal router I switch with a 24V relay on outport 1 and GND1
operated by the command M3 and M5. Flood and mist where possible to switch on the Mach3 screen.
Will report more later.
Hi guys!
Unfortunately, I read this forum very late. I bought this controller - Nvum v2 4axis ... and am now trying to get it to work.
1 problem - after 30 minutes of work, the controller has lost the bin file. I found the bin file and restored it to work.
2 problem - after an hour of work, the controller stopped connecting to the computer!
I think the firmware is lost.
How can I restore the firmware?
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.

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
Hi the bin file was there
https://www.nvcnc.net/nvum.html
for some reason the link does not work anymore. Let me know if you solve it as i need the bin file as well but cant find it anywhere .
Hi Drulo,
Would you happen to have a bin file that seller sent to you? I'm looking for the bin file for Nvum v2 also. Thank you.
Is anyone have a nvum v2 bin file that i can download? My stopworking after update the firmware.
thank you,
to. IANR23
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.
I'm also looking for the .bin file for EC500/NVEC400, someone have them?
Hello. I also need .bin file for UC300 https://www.nvcnc.net/uc300.html, i try to update firmware with .bin file from here https://bulkman3d.com/resources/ (this is were i bought the controller) and now stop communicating
with computer. Does anybody know how to reset to factory this controller.

Please delete this one.
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.
