I have purchased one of the new technology 'N-motion' cnc controllers.  I purchased this partly because it appears to have been endorsed by the Mach3 / Artsoft people. I also want this as I am using closed loop stepper motors with the hybrid servo drivers.  in order to connect up the drivers I need the connections that are available on the Nmotion controller.

In the installation manual it says that it is necessary to download and install the 'Nmotion.zip' file which contains the file 'usbmove.dll' a customized .dll file that has to be loaded in to the Mach folder.

The problem is - NO ONE tells you where to get this file.  I did some searching and the best I found was a Chinese version that was on a non-translatable website.

I am VERY upset that the Artsoft people would endorse such a product when it isnt properly supported.  Even the user manual is difficult to find but I finally did get a copy of that, but no .dll file

Can anyone on the forum help me out here and give me link as to where I might get this file?

Hi,

I purchased this partly because it appears to have been endorsed by the Mach3 / Artsoft people

I don't recall seeing anything about this board and certainly not from Artsoft/NFS. Where did you get that info from?

I am not aware of any endorsement for this product by Artsoft - sounds like a bit of deception by the vendor in the sales description of the product.

Ideally you should contact the vendor or manufacturer of the product you have purchased for after-sales support but as others have found that support is sadly lacking in the cheap far-eastern products.
However, I have attached a copy of the usbmove.dll which I hope will enable you to proceed.

Tweakie.

I am sorry you have had a hard time with that motion controller, but it is not endorsed or supported by Newfangled Solutions.

Hi pstenabaugh,
where abouts on the globe do you hail from?

Thanks to everyone who has posted on this issue.  I cant find my invoice for this item, however I recall when I purchased it last year, the seller was advertising the Artsoft logo, so I assumed that those folks had checked it out, or tested it and were supporting the product, but perhaps not.  At any rate, one place where it is currently available is this place... https://www.thanksbuyer.com/upgraded-nmotion-mach3-6-axis-usb-cnc-motion-card-interface-adapter-for-engraving-machine-servo-step-motor-45150 .... this guy also retails on ebay as well.

Doing an ebay search for 'nmotion mach3 cnc controller' yields several places in China for this unit.  Be careful though as prices vary quite a bit. This controller will handle up to 6 axis machines, which is what I purchased for about $170 US last year.  I see it now for $153 US plus shipping.

I purchased this as I am installing some closed loop stepper motors (with built in encoders) and the matching hybrid servo/stepper drivers.  I initially started out with an 'NVUM' controller but couldnt get it to work properly as it kept killing my USB port, so I would have to reboot to get it going again.  10 minutes later it would die.  I checked some blogs and found others that were having the same problem so I looked for something else and found this nMotion controller.  I contacted them initially and they confirmed this controller would work properly with the hybrid motors so I bought one.

If this works it will be great as there is a full - error checking closed loop - between the motor and the driver, via the encoders, so supposedly there are not more missed steps.  There are several suppliers for these motors in China, but if anyone is interested, then email me and I will give you my contacts.  These motor/driver combos are approximately $120US per kit depending on the motor size etc.  Make sure you order a matched set.

I am sequestered in Calgary, Alberta if anyone is from this area. Please feel free to PM me.

If/when I get this beast operational I will post back my results.

Thanks all.

Hi,
funny, I've been running open loop steppers for four years and haven't missed a step since I tuned them
in except when I've been trying to do something really dumb. Must be a Northern hemisphere quirk....this
missing of steps.

Craig

Same here, no missing steps ever except for when I do stupid. However I just machined a stainless part that took 2 hours and the center hole is perfectly round and NOT concentric with the round housing all cut at the same time! However I suspect a loose coupling between a motor and ball screw as the culprit. Missed steps would have been way more random.
