I'm happy it works for you. The problem seemed to start happening to me when I put a fairly new spool on the printer. I haven't actually compared the two spools, but maybe it was because the new spool was wider or narrower, or had a smaller or larger hole. In any case, I have redesigned the triangles, and I'll print the new ones over the weekend.
In other news...
I've fitted three lights to the bottoms of the top frame of the printer. These light strips come with adhesive backing, and are the right length to fit neatly into place. I've wired them to run off the 10A 12V supply for the heated bed.
I've also added a 4-relay module to my Raspberry Pi 3 (running Octopi). I'm using 2 of the relays at the moment... one to turn on/off the lights, and one to turn on/off the heated bed. The third will control the 12V power to the printer itself. The fourth relay is spare. The reason for this (and the lights) is that the printer lives out in my garage. I watch it via the RPi's camera. In any kind of emergency, I'll be able to turn it off remotely. Also, I'll be able to turn off the heated bed (hopefully automatically) when the print finishes. I want to turn the lights on/off remotely so I can look at the printer without leaving the main garage lights on. Actually, whilst the lights + camera work OK, the colour that the camera shows is very blue. Maybe "warm white" LEDs would give a better colour? To make the relay board and RPi3 work together, I had to change the RPi 5V power supply... 1.6A wasn't quite enough, and the Pi would reboot each time it turned a relay on .

Nice looking design. But if I'm going to change extruders, I'll have a flying extruder above the effector.

A quick question for people.... What's the largest size object you've successfully printed?
The reason I ask is that I'm struggling to print my redesigned spool-holder triangles. The problem is quite consistent and repeatable... when I print more than about 70mm from the centre of the bed, a motor skips. It appears that beyond about 70mm, there's too much force needed to move the head. Sometimes a belt tensioner breaks, and I think this was what caused my carriage lugs to break too. (I'm not making my belt tensioners any stronger, since they're easier to replace than a broken carriage.). Whether a motor skips (and which motor skips) depends on the motion of the head. Given Delta geometry, this means that subsequently, actual print height may be above or below the previous print height for the same layer). And of course this wreaks havoc on print quality.
Looking back through this thread [forums.reprap.org], I see @tidehunter apparently printing quite a bit further out than 70mm. How is that working for you?

Thank you very much!
Some good ideas for me to work on.
- Obviously Zonestar have never actually tried to print 180mm across, otherwise they would have run into this issue. I'll look into this tonight.
- I have curvature issues too. For the time being, I've just added layers of tape to the bed so that it is curved to approximately the same shape as the nozzle path. (This works reasonably well, but does make the bottom surface of prints quite ugly. Fixing it properly is still on my to-do list... I'm also planning a borosilicate sheet. How did you "correct the curvature effect half millimeter per half millimeter"? Have you seen this page? I intend to use that as a starting point... hopefully it will be good enough to solve everything.
- Will look at reducing those... thanks.
3b. I knew that, but keep forgetting.- Yes, I've noticed that too. And that an end-stop will trigger at slightly different positions. I'm thinking about removing the metal blades from the end-stops so that each carriage presses the button directly. Also thinking about making the end-stops adjustable so that they can be levelled. Incidentally, don't have any loose belt sticking out above the carriage, as that can trigger the end-stop.
Some good news: I have (I think -- I very nearly got them right on the first attempt ) finished the design of some mounts to attach the LCD to the 2020 top frame. They're very straightforward and connect to the same mounting points as the existing acrylic legs... you use a couple of M3 screws and boat-nuts to attach them.
