I am Y connectors to run the two point motors in crossovers from one controller. I am finding them less reliable than single points. I often have to operate them a number of times to get a clean change. Is there any solution to this other than using a separate controller, with the same address, for each point motor?

You need to ensure that both motors are very accurately set up to ensure their range of movement is simultaneous.  This enables you to set the movement on the controller to the minimum and ensures that neither motor is driven hard against the stop.  This can cause sticking.  There are some who would also suggest adding an omega to the linkage to minimise stress on the motor but I found that slackening the screws off just to allow a very small amount of movement also helped reliability noticeably.

They are tricky to set up and do require thought and patience but they can be made to work reliably and smoothly.  I also had challenges when I removed the spring as this allowed the blades to slacken out of their pivot and caused the tie bar to rub against the next sleeper, again causing resistance and unreliability.  If you go down the path of introducing some mechanism to hold the blades in position you may again find increased resistance causes unreliable operation.  I ended up using two semi-circular pieces of plastic cut from below sleepers and glued onto the next sleeper to the tie bar kept the blades in position while offering the least resistance.

Hi

Thank you for this. I had read many of your points in other responses and I understand what you are saying. They are not easy to set up. I have spent a lot of time on them and have them all working but then I come back to them and the odd one is failing again. I do find sometimes that replacing the cable solves it. Also for ease of originally installing ( sadly age mobility issues) the cables are on the long side. I am wondering if I am on the border of their operating maximum and that is the reason for the problems. That is why I am wondering if using two controllers for each crossover would be the answer.

Ron, I have the same issue, admittedly now pretty infrequent as I have learned a lot since I started to play with them, but I would still not consider them reliable enough for automation.

There is no doubt about it that using two seperate channels of a controller would be less demanding in terms of precise installation.  You could then of course adjust them independently and then assign them the same address so they would still work simultaneously as a crossover with the only downside being that you have used another control channel which could be seen as unnecessary expense. 

I'm sure I saw a post one day from DCCconcepts stating a maximum number of extension cables to ensure a continued reliable signal so hopefully someone can confirm.

B, I agree completely with you. Yes I was going to number the controllers so the crossovers would still operate together. I don’t really want the expense of additional controllers but I will get very frustrated if they keep failing. Although I have been building the layout for 18 months, I have only just finished track laying and cabling and having trains running. By the way can you buy the controllers without the point motors? I have only seen the packs of 2,6 or 12 point motors and controllers.

They are certainly not listed on the web site as individual items but there again everything has been out of stock for some time now.  I would speak to DCCconcepts and see if they are prepared to sell individually and when they anticipate seeing stocks again.

The control boards are not available separately, sorry. It does take some care in setup for crossovers, and a slight softness in the mounting will help. By the way, the linkages should stay semi flexible, so please don't be tempted to make your own out of wire heavier than those supplied (0.2mm), as it will make it much harder to get right. Also be careful that linkage ends cannot catch on track-bed or board.

Hi Richard

Thanks for this. I am aware of the issues you raised. I believe my intermittent problem is not physical but electrical. They all work fine but then from time to time, particularly with the crossovers, they will fail to operate or will decide to move over a different range. I normally make no change to the motor but replace the cable and it works. That is why, with the long cables
I am using because of the way I have installed the controllers, they are working at their extreme. And also why I am considering splitting the crossovers between two control boards with the same address. If I do that I need more controllers and it is unfortunate I would need to buy the point motors, that I don’t need, with them.

Regards
Ron

Hi Ron

Did you call and talk to Mick or John - they may have some insights that will help
