Did you check that all the small plastic thingies that mark installed tracks are still in place?
Maybe the load of the old loco was so heavy that the bridge of the turntable touched one of those and pulled it out of place.

Hi Fernando
I think many issues come fom the very flimsy structure of the TT:
- Märklin redesigned the support of the TT (now a ring instead of 6 small Z-shaped holders
- you started having problems when a heavy loco was used
- many other complains from marklinists

I think, one way to correct this is to prepare a thick plywood (15 mm?) support round with cut-outs (for the motor, etc) and ears (for the threaded rod supports) to come into contact of the bottom of the pitt.

The whole support plywood plate is to be attached to the main layout board by means of six threaded rods and nuts so that the support can be solid and precisely adjusted.
This is a general disease of most turntables. I have a 7286 (Fleischmann / Märklin) with similar problems but far less than on this new Märklin TT.
On this TT, the bridge's weight rests with the outer circular rail and this is where the TT needs the most support

Another thing to do is to re-initialize the TT (In case an electrical contact glitch caused the decoder to lose its data.

And of course check the presence of all these small tabs for optical detection that may be extracted by the TT when ere are too large mechanical constrains
If they are all in place, don't touch them.

Cheers

Hi Fernando
Assuming you have a CS3
- you must start with a back-up of your CS3 for safe-keeping
- then you select the EDIT tab (top right of screen
- then select edit article list on the drop-down menu
- next find where your DS is located (Drehscheibe or Turntable -TT - in German)

Here is the same on mine (but with a different TT model 7286)

- Select it and delete it.
- If you azre in MFX, the TT will register again. If it does not then return to the main screen, select the EDIT tab and then, in the drop-down menu, select "Discover MFX items like here



- then select edit TT (click on the TT symbol and then push the RIGHT ARROW (bottom right of screen)



- Pushing the arrow you get this screen



- before re-initiailizing the TT, position it to the position you wish to be track 1 using the upper field "Correct Track 1")
- once, this is done, then push "Start Programming"
- The TT will then scan for all track positions (whether there is a track or a "concrete border") each time emitting a different sound for tracks or for borders.
- when this is finished, you must leave this {programming} screen by selecting CLOSE.
- now, when you select the TT, you will see your TT exact configuration and you may drag the TT image to the wished position and the TT will follow.
Here is the video from Märklin but in German so you may correct potential mistakes I have made because I don't have this TT but another one



I hope this helps
Cheers
Jean

Jean,

Disassemble the TT, check if the pukos were correctly placed, everything is correct. I reinstalled the TT and followed the steps you suggested. Nothing worked, even the configuration shows places to stop and in those places it did not change the puko, a disaster. I wrote to Marklin and after a few days they replied asking me to send them the TT. It's frustrating, the TT is not exactly cheap and it has worked for me for very few days. By the way, Marklin answered me that using the TT with such an old and therefore heavy Loco should not cause problems.

Thanks Ross. This Morning I wento the my Marklin Dealer and they will send the TT to Marklin after Christmass, Marklin do not accept any shipping during this peiod.

Hi,

it is impossible to turn the wheels!!! Nothing is blocked. The gearing does not allow this. Worm gear! Most of the new models have this- for many years.

Did Marklin give you some information on what was wrong with the TT ? I had to send mine back for repairs like you did and I want to compare notes
.

Regards
Greg

Try this time by use DCC protocol when you add turntable to the CS3.
By the way...turntable should handle with heavy locomotives without the problems.

Märklin recommended by use DCC protocol when you shall program and change value in some CV adress.
Similar same way when you use digital signals.
I never use MM protocol when i did found out more easier way by program with the DCC protocol.

You can use MS2 as control for the turntable too.
I did not said if i have turntable.
I did just recommended what Märklin too suggested.
You can always try by use DCC protocol too with the turntable via MS2 or CS3.

But you are not the TS who has the problem.
I did just suggested to other that they can use DCC protocol too with the turntable and i found out more easier way by use DCC protocol which also Märklin do recommended too.
You can program to DCC via mfx in the CS3.
The reason why i like DCC is just because possible by use other digital system by use DCC with Märklins turntable.
Severals other Märklinist do have similar same problem like TS and i am not surprised cause of bad quality by Märklin.

Where do Märklin recommend this for the turntable? This question has been asked before in this thread, but so far you ignored it.
You do not have that turntable, as I understand it.

Theoretically the turntable can be operated in DCC mode using an MS2, but it is not possible to activate DCC mode of the turntable using an MS2.
Thus DCC is not a simple option for turntable owners who only have an MS2 as a controller.

I did checked after Trix turntable and it has same decoder like Märklin.
Trix turntable are set at DCC but can also change to MM by use CS3 via mfx protocol.
I am glad that i didn´t bought Märklin turntable since there are not 100% good product.

Hi everybody,

I'm really frustrated, having recently installed again the TT it has suddenly blocked up there is no way for it to move.

I have done everything to unblock, reinstall it, etc. It has been blocked because I have inserted a very heavy machine, the first loco I had, which is from 1965 and digitized. I have contacted a Marklin Spain Technician and he has confirmed that this product is having many issues, has confirmed to me that when we use a very heavy loco and since the pukos to detect tracks are made of very thin plastic, the plate sinks due the weight of the loco a few millimeters and it blocked the TT.

Marklin Spain requested to me to send the TT to them, they will try to unblock and avoid to send it back to Germany.

Marklin Spain has designed a plate to prevent the TT from sinking due to weight. In the following link you have all the details:


https://www.marklin-spai...icializacion-de-esta.pdf

The document is in Spanish but there is a lot of photos with the description of the plate.

I planned to install this plate

you are right, but......

You are right
