The new carriages work, and I have gained 30mm with the flipped design. I also seem to be able to print via USB now, thanks to a new cable. (should always try the obvious things first)
The carriage is designed for Bosch Rexroth/Motedis aluminium extrusion, but could be tweaked for other makes. I am using the following fittings with mine....
M3 x25mm Socket Head Cap Screw & M3 Nut (Wheel tension adjustment)
M3 x 20mm Hex Head Screw & M3 Nut (Belt adjustment, If you don't have a M3 hex bolt, a normal SHCS will probably work if you glue it in place.)
4 x No 4 x 1/2" Pozi Flanged Self Tappering Screws (Fixings for rod carrier/carriage)
3 x M5 30mm Socket Low Head Cap Screw (to replace the M5 screws supplied with the mini v wheel kit)
2 x M2 x 6mm Socket Head Cap Screw (to hold the belt loops in place)
Regards,
Les
Oh, I might try this someday... I always wished to have a mechanical way to apply force the the belt instant of using my arm
I also need to use this new effector... if I can find a way to print ABS without heatbed and/or have my new printer !

It maybe that all that is required is a tube with a larger, maybe 6mm, ID. As everything is held in tension by the spring the end of the tube may be a suitable 'housing' for the ball

My heated bed turned up from Aliexpress today, that's much quicker than I was expecting. Not sure if I could print on it directly though, it looks a little domed when I hold a straight edge on it. It also looks like I could drill a hole in the middle, between the wire connecting points for a thermistor, as there is a small area clear of tracks. Now I just need a bigger PSU and thermistor.

Les

E3D Online do the Semitec thermistor's which are quite good and I got some LED supplies of Ebay 12V 400W 32.6 amp for just over £20

Depending on how good your soldering is you could use these :-

They aren't too hard to solder and it saves drilling a hole.

I just stuck it to bottom of bed and the reading is exactly the same as my infra red thermometer

Thanks Doug, Ooznest have the thermistor and I want some other bits from them too, so I'll probably just grab it from them. I have had 2 x 12V supplies already from Ebay, I would like one without a fan, the largest being 300w (£17.20), which should be plenty for my setup.

I did think about SMD but don't think it's practical for this situation.

Did you use thermal glue?

Usual way is to use Kapton Tape.

I have just installed a heated bed in my cherry pi.I have a big enough power supply to run it,But im finding that 5 minutes into a print the screen dims and the motors stutter and then the printer stops,Do you think this is a heat issue.

Gentlemen! I think I'm back in the game. I've had a little break and now have funds to attempt it again.
Can I ask, have there been any major design changes? Andy, has the thingiverse still got files compatible with most of the kit I received? I think I need to get new carriages, rod carriers, effector assembly, filament feed assembly and the smaller top pieces to get things running (the end caps I can print once successful).
I know the carriages almost have to be made from PLA (so they have flex for adjustment, around 33% fill?) and that the effector needs to be ABS for rigidity.
There were a few things I know I could have done better originally so I'm confident build #2 is going to be successful!

Don't forget to drill the hole in the Z tower to allow the wires from the hot end and the extruder motor to pass through to the front v slot. ...The position of the hole depends on how big your filament spool is and, therefore, where the extruder sits on the rear tower. The hole is drilled just below the extruder.

Has anyone else had issues printing the effector (non-magnetic one, of course) hosted on Thingiverse? This is the one titled "Z_Probe_Effector_J_Head_Non_Magentic". I just had someone off 3DHubs try to print it, but it's failed on what I think are the loops for the bolt which holds on the fan. When I import the model into Solidworks it says there are over 2,000 errors with faces, which it fails to heal.
I'm sure it's just my bad luck, as usual, haha.
EDIT: Your build is looking really nice gowen! Keep it up!

So just my luck? Hahaha. I'm sure there's nothing wrong with the model, just might be a random error, possibly localised to Australia!Quote

You shouldn't have an issue. All the models I posted to Thingiverse were checked in Nettfab first. No one else has reported a problem. I print the effector in ABS with a 0.2mm layer height and 33% in fill

Does seem awesome but didn't seem to do anything? Solidworks still found the same number of face errors in the -fixed file?
