I am looking for a DMU 50 post for the Siemens 840D controller and can't seem to find it. Anything helps!
Solved! Go to Solution.
Thanks for raising your concern via Forum.
There is no specific Milling post for 'DMG DMU 50' with Siemens controller in HSM post library.
I think Siemens SINUMERIK 840D post in HSM library would be reasonably close to your machine NC program. You can download the same in below link:

Change the kinematics of the post to suit DMG DMU 50
1. Search 'onOpen'
change the kinematic of post from this:
if (false) { var aAxis = createAxis({coordinate:0, table:true, axis:[1, 0, 0], range:[-120.0001, 120.0001], preference:1}); //var bAxis = createAxis({coordinate:1, table:true, axis:[0, 1, 0], range:[-120.0001, 120.0001], preference:1}); var cAxis = createAxis({coordinate:2, table:true, axis:[0, 0, 1], range:[0, 360], cyclic:true}); machineConfiguration = new MachineConfiguration(aAxis, cAxis);
to this:
if (true) { //var aAxis = createAxis({coordinate:0, table:true, axis:[1, 0, 0], range:[-120.0001, 120.0001], preference:1}); var bAxis = createAxis({coordinate:1, table:true, axis:[0, 1, 0], range:[-120.0001, 120.0001], preference:1}); var cAxis = createAxis({coordinate:2, table:true, axis:[0, 0, 1], range:[0, 360], cyclic:true}); machineConfiguration = new MachineConfiguration(bAxis, cAxis);

I have a post that I've modified extensively for our 1st generation DMU 50s. The only thing that isnt working yet is automatic probing
Any way you can DM me the files? Thanks! I’m hoping everything from the first gen to the third is roughly the same!
yeah just change your B axis limit because I believe yours goes more negative than the first generation. and change your home positions
Hi
Does it work in 5 continuous axes ???
I also have a DMU50 sinumerik 840D -5 continuous axes and I am interested in a processor station that runs in 5 axes
Yes sir. Check to make sure you don't have the 3rd generation DMU50. If you do, then the B axis negative limit is greater, so you'll have to change that. But it's an easy change. A word of caution however: always try to program continuous 5 axis toolpaths to avoid over-travelling in the negative B. Doing so will either alarm out when you go to post, or trigger the rewind logic which can be used but I personally have no experience with it and I added that code to the post manually. So whether it works perfectly or not is questionable
Hi
I tested the postprocessor and it works.
Exactly the 3rd generation DMU I have.
How to change the negative stroke limit of the B axis
Did you ever figure out how to edit the home positions to the correct ones and extend the b axis limits?
