I don’t think there is anymore except mine. Most Cnc’s here are Chinese. I bought mine from Germany through a friend who imports used machines. I used to live in Finland myself .
By the way, is it ok if I post my email address here so MarcoPry can contact me directly? I want to buy the used driver.
Cheers,
AB
florian ,
Yes that far 
You have no idea how helpful this forum has been so far. Each interaction on different questions is already a goldmine.
Thank you for creating and maintaining the forum. I've been following your YouTube as well.

Here’s the picture of my driver.
I’m not sure about the rules of posting a personal contact or PM so I can get the payment details. If there’s a direct message option please contact me through that.
Thanks

Hello mate.
I have some friend in Germany who can receive the part from you. Which one do you recommend, the refurbished one or the used?
Ab
Thanks mate!
I’m from Ethiopia 🇪🇹.
I know a good electronics repair shop( they repair laptops and other consumer electronics) if I give them an iSight of what needs to be repaired
I can have a friend buy the item from me from Europe as well.
Hello MarcoPry ,
First off thank you a lot for taking your time to help!
I swapped the drivers and the problem went to the swapped axis. I’m kinda relieved to have narrowed down the problem but I’m assuming it’s a big issue?
What’s the next step mate? Give me the good news first 
Cheers
AB
Mahoist ,
Thanks for your help. I did change constant 310 to 0 and it moved in the plus direction with out issue. But it got stuck when I tried to move it in the z minus and after restarting the hydraulics and try in the -ve Z, it gives out Z04 and I05 errors.
Here’s the picture of the axis controller
Hello bfgh , Bernhard,
I’ve checked the constants and they are a little bit different.
210,211,212(1667,50,50)
260,261,262(1389,50,50)
310,311,312(1667,50,50)
One more thing, when I lightly tap on the glass scale connector rod(not the scale itself but the round rod thingy) it gives out error Z07. I did this to see it the scale connection is loose.
Cheers,
AB
Alles anzeigenHello
The Error means Dynamik following error, maby something is loose (Pully to shaft cuppling), you can change the MC81 to C1 than you see the following error displayed in the Axismonitor distance to go when you jog the axis.
kind regards form austria

Hello Bernhard,
Thanks do your feed back. Yes I did that and PdVga had suggested to try out to move the axis manually and see some backlash but I nothing seems off in that regard. It was working fine until I tried to machine a slightly bigger stock than yhe z travel.
Can I take of the glass scale and clean it with alcohol? I’m worried I might not be able to put the scale back within tolerance as the place is really hard to access.
Regards,
AB
Any suggestions for error Z09 guys? I kinda stuck and hoping to get some feed back.
Cheers,
AB
Hello PdVgA ,
I hope you have a good holiday.
Any follow up suggestions ? Can I just remove the glass savages and clean it and try? I don’t want to ruin something that I can’t fix back. I’ve bought lens cleaners for this.
Cheers
Das hört sich nach großen Umkehrspiel zwischen Antrieb und Messsystem an. Stell mal einen Magnetständer auf den Tisch und die Messuhr an den Spindelstock. Not-Aus muss betätigt sein! Nun die Riemenscheibe am Motor oder an der Gewindespindel langsam hin- und herdrehen. Die Messuhr muss sich bei Richtungumkehr sofort mitbewegen, sonst hat der Antrieb Axialspiel.

This sounds like a large backlash between the drive and the measuring system. Place a magnetic stand on the table and the dial gauge on the headstock. Emergency stop must be activated! Now slowly turn the belt pulley on the motor or on the threaded spindle back and forth. The dial gauge must move immediately when the direction is reversed, otherwise the drive will have axial play.
Hello PdVgA,
I tried with a dial indicator( 0.01) resolution and the response is similar between Z and X axis.
When I jog at (0.001) increament only 0.005 mm, the following error(distance to go ) for the Z is 0.011 the rest of the the axes it’s 0.001.

Hi PdVgA ,
Thank you for following up mate.
I’ll check with the exact following error for the Z axis tomorrow. As for X and Y axis, the error fluctuates + - 0.001. The Z axis is quite high. And yes the motor rotates for the Z axis when manually jogged. But it freezes up trying to change direction after manually jogging the Z axis.
Cheers
Alles anzeigenBewegt sich die Z-Achse (Spindelstock), wenn Du eine Achsrichtungstaste z+ oder Z- betätigst?
Bitte kläre erst mal, ob das Messsystem der Z-Achse überhaupt und in richtige Richtung zählt!
Dazu
- Hauptschalter Ein
- Not-Aus betätigen
- Z-Achse von Hand an der Riemenscheibe oder Motor nach hinten bewegen
Die Z-Anzeige muss den Betrag in Plusrichtung hochzählen (auch ohne Referenzpunkt)- Z-Achse von Hand an der Riemenscheibe oder Motor nach vorn bewegen
Die Z-Anzeige muss den Betrag in Minusrichtung runterzählen (auch ohne Referenzpunkt)Zum Vergleich kannst Du das auch mit der X-Achse machen.
Danach machen wir den nächsten Schritt.
***
Does the Z axis (headstock) move when you press an axis direction key z+ or Z-?
Please clarify first whether the measuring system of the Z-axis counts at all and in the correct direction!
For this
- Main switch on
- Activate emergency stop
- Move the Z-axis backwards by hand at the belt pulley or motor
The Z-display must count up the amount in plus direction (also without reference point)
- Move the Z-axis forward by hand at the pulley or motor.
The Z-display must count down the amount in minus direction (also without reference point).
For comparison you can also do this with the X-axis.
After that we do the next step.

Hi there,
Thank you for reaching out. I did try to move the Z axis manually following your instructions and it does reads correctly both in the positive and negative directions.
Thanks,
Ab
hi,
please add your machine Eplan number and your software version to your signature please,.. because there were too many machines made by maho..
there could be several issues
- loose glass scale
- problem with the 3TRM2 axis controller
- problem with the measuring card
Hi there Florian,
I’m stuck mate. Any suggestions?
Thanks

Alles anzeigenHi,
just an idea, did you check your wire connection to the scale? If you said macine was working before to "low" position in Z axis...??
Perhaps is your scale broken cause of that...don´t know scales of your machine but i think you have Heidenhein glas scale,i have old one philips..
So check your wire conectors and readhead on scale NOW,i think you desk (Z axis) is still in lower position...
Then you have to move by hand your axis up,think you need two person to swich off break for Z and at the same time hold and turn on motor axis upwards somewher in the middle..
Then brake again befor axis fall down!
Then check your wire and connector or/and display if there is some change...
This is only as try,don´t know exactly if i´m right,and take care of your self......
Regards Tomi
Hi Tomi,
My Z axis is in the horizontal. Just looking from the outside, the Z axis scale cables seem fine. Besides, when i manually tap the connector to the glass scales, it gives out some reading. When the machine is in Idle mode, the X and Y axis flicker 0.001 but not the Z axis.
Some one suggested in this forum or CNC zone that cleaning or changing relays for the axis seemed to work. Do you know which relay/contactor corresponds to the Z axis.

Hi Everyone,
This is a repost on the english section.
I need help with error Z09 on my maho MH600E2.
Should i remove the glass scales and clean the insides? I've enabled constant 81and, X and Y shows a slightly fluctuating 0.001 but not Z. When i sometimes get success and move the axis on manual mode, the Z is way off like 0.124 or something similar. I was running fine a day before this happened as I was face milling a slightly oversized stock (470mm on the Z axis as the axis limit is 450mm)
Thank you

Greetings florian
Incase this helps, the day before it displayed the error, I was face milling a little over sized material in the Z direction (470mm) without issues .
Hi Florian,
Than you for reaching out. I'm not quite sure if I've updated my profile correctly due to language barrier.
My machine is Maho 600E2/5.2 ,Serail number 64903 ,Software version 6603.602/04.
I hope this help.

Hi Everyone,

I've come to this forum via google search. I've tried to follow some of the conversations via google translate and tried most of the suggestions but the error is still there.

Thank you for taking the time to read my problem in English 
Any help is appreciated
