Retrofitting Deckel FP4ATC

My original Maho wiring diagram was wrong for the EXE wiring. I also had to try other pin outs. IIRR Heidenhain seemed to always use one of two pinouts, and the other one worked for mine.

Hi Mbrandt,

I have the EXE 257 411 01 and I have documented the wiring from the D-Sub plug of the EXE to the MESA 7i97T.

Best regards

Hartwig

Have you looked in the bottom beside the battery. its a normal place for the upgrade modules ?

Hello! 
Finally the wiring for the EXE and Mesa that worked for me:
I also dont need a extern  12V supply.

Mesa name  /   EXE Pin and colour
1 QA0         /     9  braun
2 /QA0        /     14 grün
3 GND        /      3 grün-weis
4 QB0         /     1 grau
5 /QB0        /     4 rosa
6 +5V          /     2, 6, 10 grün/braun
7 IDX0        /     7 rot
8 /IDX0       /     15 schwarz

And finally the references work! I only can drive the joints very slowly to find the index. Is there a way to drive faster? The index is only 0.001mm wide. sometimes it wont pick up. 

I also milled the first pices! It works great!



I have already recived the 7i74 und the 7i84U´s for the extentions.
On the weekend i will hook up these so i can use the diffrent gear for the spindle. 

Really a cool milestone to make the first parts. Congratulations.

On my Maho I have:
HOME_SEARCH_VEL = 0

HOME_LATCH_VEL = 10

HOME_FINAL_VEL =15

Thank you!

I have already tried a bigger LATCH numer but it would just miss the index. Currently I usind 1.

Mabey I just leave it like that.

And what speeds would you recommend to cap the machine? I currently use 4 m/min. Is it recommended to go higher?

My Maho was originally only 1,5m/min with the Phillips 432. I have it set to rapid at 2,5m/min, and it is fast enough to crash before I react.

Hahahaha thats defenetly the case with 4 m/min.
I will propably leave it as it is.
Originaly it has also 4 m/min.

Hello everyone!
I am currently connecting my two 7i84U and my 7i74 to my 7i97T. 
But i have a few problems with it. 
Can someone please send me the right firmware for that config? I have tried a few and it wouldnt work. Also the encoders stopped working after the new firmeware. Does anyone have a solution for that? The 7i74 and the 7i84U has power. And the leds work.
