The Mazatrol protocol is pretty special, and it takes some effort for software companies like ours to write that code. That's why it's not cheap. If Mazak had their way, none of the DNC vendors would have any software available. Mazak has never published the protocol, and all the DNC companies who offer Mazatrol software have done it without Mazak's cooperation. That's not easy. I seem to remember a cheap-o cassette recorder that Mazak offered for $2000 back in the 80's.

Free V24 Dnc Software. 2/11/2018 0 Comments. DNC software for easy RS232 CNC file transfer - great value for machine shops of all sizes. DNC software for easy RS232 transfer and dripfeeding to CNC machines, using real or virtual serial ports, USB to RS232 adapters, direct TCP/IP wireless RS232 and FTP. Watch32 do not host or upload any. 1 month free. Rating is available when the video has been rented. This feature is not.

That's why several DNC vendors tried so hard to offer an alternative. Our PC-DNC Editor does both G-code and Mazatrol for a list price of $595.00. If you want it for less, then make us an offer and we'll listen.

The link for a free demo copy is: The operator's manual is at. Hey Pi how do you use hyperterminal to transfer an nc file? I saw that it will only accept.ht files, It would not allow me to open a.nc file.

Select 'send text file' and it will send them. Most people running mazak mills use g-code and not mazatrol.

Cimco and predator also send mazatrol files. Camware by mazak also works well. Pc-dnc is not the only software capable. All these packages are on my hub and membership for unlimited access to download all of them is less than what dan charges just for pc-dnc.

Yt. So far I have the demo's for: Dan's PC-DNC as linked above Thus far I am testing for GUI and ability to save to multiple directories. Haven't yet hooked up to the machine. Opinions thus far: Dan's seems easy to use and allows easy selection of file to send. Allows send and receive to/from multiple directories. ExtremeDnc seems easy as well.

DNCMax doesn't seem to allow different store directories. I guess I'd have to save to one place and then use Windows explorer to put the file where I want it. Ezatrol, it may work, but the GUI is terrible. It's written in VB6, wonder if they ever heard of the Common Dialog control, or that cancel means abort? Also, did they ever hear of HTML Help Workshop?

Psychomill, how would I tell if my control has that option? For reference, I don't run the machine, I am just in charge of finding a way to eliminate the Greco box and floppies. Bryan, The various DNC vendors all use different file formats for those Mazatrol CMT files. Some save them as pure binary files, others save them as hexadecimal numbers in ASCII. Some save the checksums in the file, some do not. We've tried to write our software so most of the 'Brand X' files can be sent OK to the CNC, but there's no guarantee that your CMT files would be compatible with our PC-DNC Editor. Almost every week, we get a request from someone who has a bunch of Mazatrol CMT files saved by some obsolete DNC system, and we ask them to send us a sample of those files.

Generally, we can make our software open and send those file formats. At the moment, I think we have about 95% of the 'brand X' systems covered. If you have this problem, send us a couple of sample files and we'll work on it for you. Dan has some good points there.

On top of that though, if you already have files saved in 'native' format, then all you need to do is to send the programs back into the machine. Then when downloading them from the machine, just use the tape I/O to save. Now its in the 3-digit format. Its worked on everything I've run so far from M(T)32, M(T)plus, and Fusion.

Its possible (like Dan said earlier) that the older controls won't output thru Tape. So I'm thinking this might be the case with the earliest versions of M32 and older (M1 and M2). Used to use Griffo software years ago but got away from it (No real reason, Griffo is good stuff). So any programs we had still in native format, after it was loaded and ran, we just saved it as an NC file thru the Tape I/O.

Mazatrol is way too easy to use and program to have to justify 'offline' programming for us (and many other places I've worked at). Especially on lathes since you can probably program a dozen parts at the machine while you're running one. I don't care for Mazatrol on the mill so we don't use it there. The test is simple.

Just have them output the Mazatrol programs thru Tape I/O (be sure the settings are correct) and see what you get. If you get something that looks like a bunch of macro routines with 3 digit g-codes, it should be fine. Then to test that, just upload this program back into the control and see if the Mazatrol program looks correct. Pc-dnc is not the only software capable. All these packages are on my hub and membership for unlimited access to download all of them is less than what dan charges just for pc-dnc. What exactly are you charging for? If its the free demo versions of the software, then I guess it would be classed as legal,but taking advantage of someone who'll pay for free stuff, Or are you distributing cracked or modified versions of commecial software for much less than the manufacture's price?
