The factory controller is junk, I have had to take mine apart 4 or 5 different times after minimal use to readjust the copper contacts. I run mine manually as I have never been able to get railroad and company soft ware to talk to the digital controller on the table. Really, just want something simple and reliable. Any help or suggestions would be great. Thanks.

When being used in analogue environment the signal control panel 72760 must be used (your case 1 think). This unit is mostly electronics Märklin provides no drawings and you will find none because of German law. You may get a faulty item from Märklin and they change it under warranty very easily unless you open it. Then the warranty is void. I don't have this particular item, but I use Märklin items since 1961. They produce high quality product but, true you may get a falty item (rarely) Are you sure you are not doing something wrong?

It tends to flatten out the copper contacts inside the blue box and so the deck won't turn. I have taken this apart several times and very carefully re bent them and the switch works for awhile. The turntable itself is a beautiful piece and I am really happy with it. The controller is junk in my opinion. I am running my layout with Railroad and Co. and for some reason that software just won't connect with the Marklin digital controller. So I figure 99% of the time I would be at the turntable anyway, why not just manually run the table. There has to be a easy way to make a controller for doing this and connect it. Thanks for your help. Charlie

One way to address the issue is to use the TT with a digital system. Frankly I don't have this TT but another Märklin one and IMO it is just a pity you can't use it that way Here is just a glimpse of my layout with a TT under complete control of digital and association with Rocrail. A few points: - the 74861 does not connect to "that software" but to your "Digital controller" (which one it is I don't know). I use now a CS3 after having used a CS2 since 2010 - If you use an MS2, yes you may have to upgrade to a more intelligent Central Station. I think some use those MS2s with a s/w like Rocrail but you need to add some non-Märklin devices - if you can take a picture of your flat sliding contact, may be we can help. Cheers Jean

Perhaps it would be best if you posted a photo of it, so we can identify it.

LDT has a decoder that seems to be better than the Märklin one: LDT decoders There are other decoders. At least one of them has sound and uses bridge travel control through the use of light. I don't remember the brand. I think other members use it and they can better talk about it. Miguel

It comes from a document by Ross Stewart in Australia, at http://members.ozemail.com.au/~...table_analog_control.pdf
