Martin-369195

I'm thinking of scrapping my first experimental layout with a new bigger, lighter version. This time I'd like to have a go with wire in tube for the points. I'd appreciate any advice or experience on this. What diameter tube, for example, and what diameter of wire? I've seen some little switches (levers?) somewhere a You Tube video - but can't remember where. Again, any advice or suggestions welcome. Martin

@96RAF - I did do that

Thanks @LTSR_NSE, I now have a long thread in DCC / HM7000.

Cross-posting from another thread for completeness: there have been previous reports of an issue where multiple HM7k decoders cannot be operated & only the first placed on track is. The solution for these situations has been to: • completely delete affected decoders from app. • remove affected locos from track & power off phone/tablet. • power everything back on again. • go through the linking process again. The decoders should then be able to be operated together. This didn't make any difference to the power car.

I've just tried the power car again with the same result. This looks like a call to customer support.

Ah! I've got the dummy car working. There's something amiss with the dialog that accepts the device reset passcode. I restarted the app on my phone I was able to link the device.

Can't get past the reset device on the dummy car using the device reset code from the email I've selected several profiles on the power car but none work.

I'm just working on the power car for now. I can only import Function Maps, not Loco or Running Profile...

I've now removed both the power and dummy car from the app by doing the following: Manage Device > Unassign, then Unlink & Delete Device Power Cycle Then delete device (also available from Settings > Engine Shed) Restart Android Device Then: Put loco back on the track Settings > Link Device > Start Scan Select the new device Locomotive Profile Detected >Yes (fetch and import the latest locomotive profile) But: Essential updates are required before using your device > Bluetooth Firmware, APROM Firmware OK, I'll update... And then: 'A problem has been detected with your device.' Manage Device > Sound Data / Profile ROM Mismatch Where on earth am I going wrong?

Thanks @96RAF, I'm familiar with MAC addresses - I use them all the time to reserve IP addresses in my router for my virtual machines. The DCC/Bluetooth bit I'm still learning. I don't use DCC, I have only ever used HM7000 android app and Bluetooth. There's some confusion around consists here. I'm not trying to consist the power and dummy car at all and understand that, at the moment, I can only run both ends of the loco separately.

So is the solution to unlink both locos, delete profiles etc and start again? I can give that a try but they both worked out of the box first time but then stopped working together (not as in consist) after I turned the layout off and closed the app.

Thanks @Rog RJ I've just tried changing the CVs but they're read-only. How do I change them in the app?

I think I've understood this but I'd appreciate some help confirming this. The long (4-digit) address is the MAC address so in my dummy cars case that's 7580 which I get from the DCC app showing HM7000_7580. I've used the 2mm association online calculator (here), and entered 7580 giving me a CV 17 of 221 and CV 18 of 156. These CV's don't match. 192/100 suggests they're default values. So, before I start fiddling with CVs and possibly making things worse, is it just a case of changing these CV values in the app and I'm good to go?

Both have a CV19 set to 0. Ah! They both have identical 17/18 CVs of 192 and 100 respectively. They are sharing the same IP address?

I'm experiencing problems with my new TT:120 Class 43 HST set. The set arrived Friday, placed on my layout, fired up the Android app, linked the power car and the dummy car as separate devices and it (they) ran beautifully. Saturday, fired up the layout for another session. HM7000 app recognized the power car (blue blue tooth symbol), but not the dummy car. I went through the troubleshooting guide with no success, powered the layout off and left it for the evening. This morning both units showed they were online and the dummy car responded to sound commands. But now the power car won't respond to sound or movement at all. If I place just the dummy car on the track the app recognises it and responds If I place just the power car on the track the app recognises it and responds If I place both cars on the track the app recognises the power car which responds, but doesn't recognize the dummy car. Going through the guide again: When I install a Profile to my HM7000 decoder, my locomotive no longer functions - doesn't apply as they both work individually. When I open the HM | DCC app, it crashes - doesn't apply either. I've checked every loco has a unique LOCO ADDRESS. I'm baffled... Any advice folks? Martin

Thanks @Fishmanoz I went through the troubleshooting guide with no success, powered the layout off and left it for the evening.

I'm baffled... Any further advice folks?

It arrived! And worked OK yesterday evening. Today, the dummy car won't play. I had this with the Scotsman and it was a faulty chip and ended up back at Hornby. I've unlinked the device but I'm not able to relink. Any advice? Martin

Mine has just arrived! 1.5 hours of work to go. I might finish early!

I only bought a couple of packets to join my yet to be built custom track to Hornby's set track. I'm not worried about purchasing more ... I know a dealer .... Martin

Hmmm. My pre-order was placed 29 January 2024 and 'Your BR, Class 43 HST Train Pack - Era 7 (Sound Fitted) pre-order has arrived at our warehouse and will shortly be prepared for dispatch.'' email arrived yesterday. I suggest you give customer services a call to find out what's going on. Martin

What is the right way to upload small videos on the forum? Is it possible or does everyone upload to YouTube and post a link? Cheers, Martin

The Hornby stock alert email thing happened - two days after my order of them arrived!

Thanks for the post, Moccasin. The Hornby stock alert email thing didn't happen. Perhaps the email queue is full of HST order emails...

When I've made further progress I'll post updates on a new thread. It could be some weeks though...

I watched Peachy's video(s) and I purchased Dapol couplers, West Hill Wagon Works couplers, some Hornby couplers and after playing with them for a while I agree with Peachy's observations: The Hornby couplers are cheap but you need a miniature crowbar to uncouple them manually. The Hornby uncoupler is OK but needs a hand of god. The WHWW are better and more expensive but snap together unrealistically. The Dapol couplings are very effective, very expensive and deliver the best, most realistic hands-free solution. But you have to hack the track so fitting them to curved track becomes an issue. I purchased some small 1mm x 1mm circular Neodymium magnets. I also needed some extra tools - ceramic tipped tweezers are a must! The first experiments were attempts to superglue the magnets directly to the underside of Hornby's couplers. This idea didn't work because these magnets are very small and don't have enough pulling power (0.02kg). Next up was 2mm x 1mm magnets (0.07kg) using the Dapol couplers. This is better - not perfect - but it is working. I need to try improving the location between the rails: I've ordered 3mm x 2mm (0.27kg) magnets so there's another set of experiments. I had a happy surprise result. The 1mm magnets attached to the Hornby couplers also seem to work with the 2mm magnets in the track, but the polarity has to be reversed. What I mean by this is that with the Dapol couplers the magnets in the track need to attract the pin in the couplers whereas with the Hornby couplers the magnets in the track need to repel the magnet glued to the coupler. The Flying Scotsman is fine. I've 'extended' the nano layout with some foam packaging in case of accidents!
