So have you guys had any luck, i just picked up one of these lathes as well, the controller is quite interesting things are hidden it seems in it.

It seems like There are a few on here that run these with no problems I need to get mine going as well but other priorities have temporarily pulled me away from this ,mainly a learning curve I think because mine are built well and do all the movements good just a little different than the controls we are used to such as Fanuc or Haas
Good luck with the new toys keep us updated as you progress

Did you have a post processor that works with any other cam software's, we're you able to find the d pro program? And what part do you add to your file to get the controller to accept it when loading a file?

Yeap I've found the D-Pro Software, it should be attached as a Rar file(It won't let me, so if you want it PM me or somehow give me an email address so I can send it to you). If you've got an earlier 15S/18S etc then you'll need the Dpro-TC software for an 840C controller, the Dpro-TD software is for the later lathes than run an 840D control & the Dpro-TM is for those lathes with live tooling/milling capability. I haven't got a post processor for any cam software as I've never really needed it, though it shouldn't be hard to write one. If needed I can post up a sample MPF program which you should be able to load

I wanted to let everyone know, we got the pc to link, got a file in, i tried it and it works lol, i have a post processor for fusion 360 hsm that does work, it took a little bit to figure it all out but shes up and running.

If/when I get some time I'll try again to post the D-pro software here or somewhere so that people can grab a copy

Sounds good or email me lawsonwelding at gmail dot com, Have you ever had a problem with the spindle knocking at slow rpms, like maybe the encoder is slipping, perhaps the belt needs something, over 500 its smooth as a whistle, under it starts making noise.

I can't say we've ever had a spindle knock at low rpm, we did have a problem where one of them wouldn't run faster than about 500rpm which from memory was one of motor contactors or something like that in the back of the cabinet. The only real issues we've ever had have been tailstock proximity sensors & then the displays failing or power supplies to the displays failing. Except for our 15s which started to eat 9V batteries, it seems there is a fault on one of the cards but Siemens can't tell us which one & want us to keep buying new ones until we find which one it is, I've just wired in a 9V power supply which keep the memory going unless the power goes out, which happens about once a year

Tried attaching the software here again, won't work, tried emailing it but also doesn't seem to work for most people. So try this instead DPRO_ENG

I am having a problem with the 840c external threading cycle, when i input a negative value into R24 the controller stops at the start point and will not run the program, if i input a positive value it runs the program but rapids back into the part. I have tried everything i can think of any help would be appreciated, here is a copy of some code, i have changed z values and distances from what i am trying to do just to dumb it down for myself.
