General Mach Discussion / Re: Software Great, CNC Machine doesn't move

« Last post by Cyscrofer on January 08, 2026, 12:39:41 PM »

hi Dickey,
You're awesome. I just discovered that about the same time you posted it.

The Mach3 software didn't come on a disk. I was direct to download it here:
http://www.machsupport.com/downloads.php

I installed it, but the card driver, NcUSBPod.dll, isn't to be found in the Mach3 folder.

I googled NcUSBPod.dll, but not sure I've figured out how to find it yet. I found this page which may be the manufacturer. This page is mostly in Chinese, I'm downloading a 72mb thing now from there which seems like it might include this dll. It's a 2-hour download. whew.

General Mach Discussion / XHC MKX IV-II 4 axis board

« Last post by Cyscrofer on January 08, 2026, 11:37:41 AM »

Hi guys i need help before i reach for the 2lb hammer

Ive built a machine from scratch and fitted the XHC 4 axis board and running the old faitful Mack3 still

Sadly cant afford the Mach4 just yet

Ok so i get the dreaded Find No XHC NcUsbPod! error up

Ive hunted for three days for a suitable file and so far all i can find is dead end links or Pluggins that dont work.

looks to me like China stopping the Mach3 stuff and removing all the old files forcing us all onto Mach4

Can anyone please send me a copy of the Pluggin ive two that actuall dont crash the Mach3 software however niether allow the board to be found

Ive got the slow flashing light and ended up shorting the Estop out to give me a high constant signal as im lead to believe this can stop it working  also removed the probe which is a potentional

sadly never got a CD with any driver files on it so blind before i even start

also got the WHB04-6 MPG which is faultless and trips the Mach3 perfectly just cant see the card through the USB port

Installed Mach3 5 times now and about to give up

Its doing my tree in

can anyone help please?

Thanks and a happy new year to you all

Love reading the comments

cheers

Mach4 General Discussion / Re: Mach 4 Hobby Non-Business Use

« Last post by Steve Stallings on January 08, 2026, 10:45:48 AM »

Mach3 and Mach4 products are sold through the "ArtSoft" entity. Over the years this entity has been a freestanding company in Canada then owned by Art Fenerty, a division of NewFangled Solutions, LLC in Maine and now a division of MachMotion (aka Edge Solutions, LLC) in Missouri.

The word "license" in the context of software can refer to three different concepts.

A "license agreement or EULA" which states the rights and responsibilities of the buyer and the seller. It can be in the form of a signed contract or in the form of automatic effects such as proceeding to use a web site after notice is presented or opening a physical package with a notice on it. ArtSoft currently and historically has not used a formal "license agreement". Statements made in marketing materials or on a forum do not constitute a "license agreement".

A "license key" which is a mechanism to protect a software product which is designed to not operate fully if the license key is not present. This is the method that ArtSoft has traditionally used to protect their software. Mach3 license keys, when applied to the software, will show the buyers name on the startup screen so that it is possible to see if the name matches the user who presumably purchased the software. Mach4 utilizes a more robust mechanism that verifies that the license key matches the signature (PCID) or footprint of the characteristics of the PC for which it was issued, otherwise Mach4 runs in Demo mode.

"License policies" are restrictions presented or implemented outside of a formal "license agreement". These policies are often stated by the seller in their marketing materials and other documentation. Policies may interact with "license keys" to achieve control of usage. The "license key" for Mach4 is an example of this. A user of Mach4 Hobby is allowed to have up to 5 active "license keys" at once for Hobby use. If you already have 5 keys active, the license server will not generate a new license key until you deactivate one of the old keys. The license server also monitors activity to detect abuse of new key generation and may enforce management approval before more keys are generated. Mach4 Industrial and some optional software will restrict users to only one active license key at a time.

One policy that is stated in ArtSoft materials is that for commercial use (making money by using the software) the user is expected to purchase one "license key" for each machine that is engaged in commercial activity.

ArtSoft also suggests in its marketing that Mach4 Hobby is targeted at hobby users, but has never stated that commercial use of Mach4 Hobby is a violation of "License Policies".

General Mach Discussion / Re: Mach3 Slave running faster than primary with same tuning

« Last post by meiniecost on January 08, 2026, 04:28:25 AM »

The main cause is inconsistent settings, especially Steps per Unit, between the main and slave axes in Mach3.
Ensure that the motor tuning, microstep on the TB6600, and slave axis settings are identical; reverse the motor direction in Mach3 instead of swapping wires.
After synchronizing these parameters, both motors will run at the same speed and in the correct direction.

That's probably all you can do as Mach3 is now out of support for 10+ years. Save a copy of your xml file before uninstalling.

and a software license can include a copyright restriction, but can include any other condition that the seller wishes to enforce... and the buyer wants to agree with. So go READ the license agreement... its not in the FORUM or up to the FORUM to determine what the licensing agreement states... all you need to do is read it. If it doesn't state anywhere you can't use the s/w for a specific purpose, or if there are specific conditions for the use of the s/w, then you are free to do whatever you want to do with it ... within the laws governing what you are doing however...

Ok.. I tried to hold myself but I simply can't... first there is no legal expectation, limitation or liability in DESCRIBING what you expect your target audience to be... none.. zero...zilch... so when they state they expect HOBBY to be for anyone not engaged in certain types of work, they are simply stating that they, the developer, simply expects that anyone using HOBBY doesn't expect much in the way of warranty or support.. since most businesses expect their purchases to function and be supportable, this isn't whom they expect the end users will be. When you purchase the product, the sale will either include the license agreement and limitations, or the seller must make the license agreement available, since this is the ONLY contractual agreement between the seller and buyer. So when they indicate you can only run on one machine, its done so you can't figure out a way to 'clone' your pc, and run the license to operate multiple machines, but only at the SAME TIME!!!! YOU could use your license on a single pc to run many many machines... but only one at a time (I am not actually sure that's a part of the license agreement). You actually don't have to run a machine at all... you could never use G-Code and write all sorts of wacky code in the background and make a audio recording. the license only stipulates that you can only run a single license of Mach4, on one pc at a time. So I have no idea who or what you are... but you should either HIRE a lawyer (if you are one, find someone else), go to Law school, or go to your local library and do some basic research on License agreements. Damn....

General Mach Discussion / Mach3 metric to inch occuring during program run.

« Last post by AlanETM on January 07, 2026, 08:24:41 AM »

I am running Mach3 under Windows XP and its been running successfully for many years.
A problem has now occured where on starting a program run with a tool change setting at 50mm and work surface at zero the machine runs to z50 and immediately on stopping the Mach3 dispaly goes from 50 to 25.4, thus losing the datum setting.
I have done a number of restore settings and run previous successful programs as air cuts but they all do the same.
So I have concluded the fault is within the Mach3 software.
I have registered a Ticket with the help desk but as of writing this  I have not had a reply.
Is it worth reinstalling Mach3?
