    MillPlus Control Need Service Manual

    Hello all:

    We have several DMG machines with MillPlus controls (version V420) and it is getting harder and harder to find repair technicians. I don't want these machines to become orphans, they are still mechanically sound. Anyone have the Service Manual for this control? We need to start documenting them so we can repair them ourselves.

    Hi Dan

    I don't now if this is what you are looking for. This is the controller manual for millplus 420-500
    http://www.millplus.de%2Fpdf%2Fuserm...,d.bGQ&cad=rja
    I have a DMU 50 V with millplus controller (currently malfunctioning, An other thread) and a lot of documentation to it. If this isn't the document you are looking for a might have it in hard copy. I can scan the necessary document to PDF for you.

    Ok, we weem to have that one too. Our control is version 420. We currently have two problems.

    1 -- The machine has bad reversal spikes (not backlash) in the "y" direction; the specs for the control say that it can compensate for reversal spikes, but how to do it would be in the manual given to technicians.
    2 -- We bought a machine that somehow has lost the linear compensation values. It used to be the values were input as parameters, but now they are input as a file; there is a procedure on how to do this, but again, this is information that only the service technician would have.

    With all the changes in the DMG organization, you can't find anyone anymore that has the slightest idea how to service a V420 MillPlus machine. Which is unfortunate, because when they run, they are fantastic.

    Hi Dan

    This is at best only an educated guess. Have never tried it myself. I am still learning how the system works myself . What I can surmise when I read the documentation I have is that it is a combination of response time of the servo and backlash to reduse reversal spikes.
    Here is a link to an article describing the procedure on a Fanuc system. Other addresses for the parameters. But I think that the approach is the same. Adjusting Parameters After a Ballbar Test
    To the machine I have, I got a CD with the number of programs and a disket with some files. Including a file called CM.CM The file contains all the settings for the machine, including linear compensation values. The file should be in the System folder on the machine. I don't know If you can copy the file by using the CdsLite program that is on CD or if that program only is transferring milling data to the machine . If not there is always the possibility off removing the drive from the machine and connect it to a PC and transfer the file this way.
    I have a PDF document that lists the machine parameters for Millplus V40x and the CM file for my machine for comparison if that is any help to you.

    Hi Tobias

    Do you still have the PDF document, Finally got the CDS Lite software fromm Heidenhain but I don't know how to transfer a program from PC to the control, I guess s a parameter problem.

    We use CIMCO DNC-Max to drip feed via Moxa units since the software has been optimized to work with them. Using this approach you can get the fastest transfer speed possible via RS232. If you setup your drip feed properly as well as your path filtering in your CAM you will likely never need anything else for the machine. We routinely run our machine for more than 10 hours non-stop using this setup and it works very well. On the older Philips/Grundig versions of this control it is pretty much the only way to run them on large programs.

    Dan (Dullfig), can you please contact me? I have access to plenty of documentation on the Millplus controls but I also would like to get feedback on how your v420 install went.
