Hopefully the "ABS like" resin might glue with mek and it's friends....
Amazon have done their stuff and the Elegoo has landed. Not deterred by a torrential hailstorm at the very moment the van pulled up outside.
All beautifully packed. Now all I have to do is work out what all the bits and bobs are for -- and not muddle up the ones for the washer with those for the printer. The one I do understand is a pair of genuine Xuron flush cutters, a surprising and welcome inclusion in the box of bits.
I have to find somewhere to install the printer where I can shut the door on it and open the window, to keep the pong under control. The machine includes an air filter and fan, which is intended to absorb the fumes. But I doubt it will be very effective, and it certainly won't be every time I take the lid off.
I think I shall clear a space for it in the computer graveyard. I may be gone some time.
But first a boiled egg.
I use servos to operate all my turnouts using MERG software.
I have had no problems at all.
I use a small pcb mounted on a 3D printed servo mount .
This PCB contains the servo driver and a relay to provide frog polarity switching.
The two end points for the servo and it's speed can be set very acurately and the relay changes over half way between the the set end points. Other versions of this use solid state switching instead of the relay

The printer arrived today, two days earlier than expected.
BTW, I understand you can use denatured (meths) rather than isopropyl alcohol. Denatured is much cheaper and easier to get here.
Hi Martin,I went for the machine with an air filter because I don't get on well with solvent fumes. I prefer soldered track construction with cosmetic half-chairs mainly because I can't stand the smell of MEK/butanone for fixing functional chairs.
That's a great way to use servos. You should not have any issues with interference when the driver is that close to the servo. It's the long wires between the driver and the servo that can cause problems.
These are chairs and other fittings for an A switch...
Is it worth using a screened twisted pair, with the screen earthed, between the driver and servo if it has to be a lond run?

Is it necessary to use supports under the sleepers or can they be plonked right onto the build plate?
