In 3D printing news, I have swapped the 0.4mm nozzle for a 0.2mm nozzle and now everything takes 4x as long to print, but, oh my word, the detail.

I am now in "production" for the PCA009 & GUV designs. I needed to stop tinkering and actually make some "final" versions.

Currently printing a GUV and 2x PCA009. 40 hours remaining on an estimated 60 hour job (although it tends to over-estimate, I'm expecting this to be more like 43 hrs total, based on previous.)

Top tip: get the design right first with the wide nozzle.

Today I learnt that Kadee #19 couplings are not long enough at 10.7mm for Accurascale Mk1 coaches where the NEM pockets are recessed quite a long way back compared to most other rolling stock I own. They couple up - just - but the buffers are almost touching and a rake of them won’t go around a 500mm radius curve (the tightest on my layout).

So I’ve ordered some #20 couplings (11.7mm) which I’m hoping will add enough length to give enough clearance. If not they’ll get used elsewhere and I’ll use magnetic couplings between the coaches instead, with a Kadee on each end of the rake.

All the other rolling stock I’ve added Kadees to have been fine. Most locos need #19 while everything else is fine with #18 (8.6mm), even the Syphon Gs which I thought would need #19.

A quick #ModelRailway update. Today I mastered the Digitrax hardware - got the LocoNet cables completed and tested, and the device ids all sorted out so now all the track blocks are predictably numbered. Also got everything hooked up and working on the second reverse loop.

Finally I broke out the windows laptop to program the newly installed points controller, and fixed some small issues with the configuration of one of the others.

Also worked out how to use JMRI’s LocoNet monitoring window to help verify that configuration changes were sticking.

Nothing really to see, hence no pictures today, but a good step forward.

The same layout also had two very well modelled cyclists going round the church. Very cleverly done with a hidden conveyor belt with magnets under the road surface, but what really caught my eye was being able to get the legs pedalling. #ModelRailway

There were also some good trains too. Particularly liked this layout which was of a fictional Welsh railway station with a typical Welsh narrow gauge railway next to it. The detail is superb. #ModelRailway

This is getting silly. I now have four Digitrax BXPA1 reverse modules. The first two I bought (on the left) have both developed an identical fault, the LocoNet interface has died. I’m hoping it’s a batch fault that has evaded the other two I now possess, the second of which has just been installed over lunchtime.

Plan is to stick the faulty ones in the post for repair - they have to go to Florida for that - and then sell them on once returned. If neither of the other two develop a fault in the meantime (I really hope I’m not foreshadowing, here…)
