I am a Chinese small cnc machine company, I have 15pcs machine should be installed a PC-base cnc controller software, I think Mach3 will be good choice, but my client request the interface  should be siemens 840D interface  , I would like to know if who have modified the mach3 in siemens 804D interface?please contact me manager@yornew.com   thks a lot

Thanks a lot, I have contacted them, they have no siemens 840D screen interface

Hi,
a Seimens 840D is one of their top models, worth $20000 plus and annual licence fee for software updates.
Its as about as different to Mach on a PC as it is possible to be.

What is it you want....what are you trying to achieve?

Craig

I need a cnc software is installed in the PC(I think the Mach3 is this type software , the interface and screens of software should be same with siemens 840D, and the cnc mill machine is controlled by PC.
For my project is for education, so there are no enough budget to buy a real Siemens 840D cnc controller.

Hi,
if you don't have the budget for Seimens .......then forget Seimens.

Mach3 or Mach4 is a good low cost choice for CNC software on a Windows PC. LinuxCNC is a free open source
CNC software that runs fine on PCs with Linux (with real-time extensions) installed as the operating system.

Craig

Yes, I know those two software.but my client need Siemens 840D interface screen for teaching students, after training, student will know how to operate the Siemens 840D controller when he face to real Siemens 840D

Hi,
one of the major distinctions about Sinumerik controllers is their (Seimens) conversational programming features.
It is distinctly Seimens, no other manufacturer does it quite the same way.

If you want your students to be familiar with Seimens controls......buy Seimens.

There is NO other software that is the same.....other than some rip-off copy.

When looking up the 840D it is obsolete, Seimens ceased production in 2015. The 840SL is the current model.

If you are dead set on having Seimens control look at the 808, a much simpler and cheaper proposition.

Craig

I had used 808D, but my client can not accept

As Craig said,

you can have the look of a 840D (by creating your own screenset),
but never the functionality of it.
