The DUO 008b pump I have seemed to have a problem with it's thermal protection.
After about an hour it switched off, but sometimes it just switched off randomly.
I replaced the thermal protection switch (a relay with a PTC), and I replaced the off switch. Worked fine for 5 hours continuously after that:

And then.. after a two hour bake out at 100 deg. C, cooling down and pumping for about 3 hours until 4e-7, my TPH270 started to make an unfamiliar noise, the pressure went up, the noise got louder...
Goodbye TPH270... I don't know if I can fix it. It's probably the bearings.
But I did finish two 3d drawings for presenting the idea of the "octavio". Using FreeCAD wonderful program, really free and open source, not completely bug-free, but easy to work with, also tried wings3d but that was much harder.
