I put mine back  together already. Those screws are behind a fan and heatsink that has to be removed and on my machine I also have to remove the pressure spring on the extruder. I did not notice but did he say he lost both? CTC to my knowledge was/is pushing only dual extruder printers. The feed tubes are both inserted through a six inch long aluminum block then each locked in 0lace with their own set screw. So just measure the other one while it is apart.

I have the same machine just the metal version. They are a 2mm screw and require a 1.5mm hex key. I just measured mine since I was moving my defective extruders nozzle up for know.

Not to doubt your measurements, but if you're right then you have a completely unique set screw, which seems like a terrible waste of time and money on the part of CTC.

1.5mm hex just doesn't fit onto a 2mm set screw (the hex corner-to-corner is larger than the thread's minor diameter). Please check both those numbers? I really don't want to see the OP get sent off to special order a freaky microscopic set screw when they could have bought something in a hobby shop... smile

Anyone know which of these it would be?

it goes from 1.4 to 1.6

I've not received those blocks yet, since coming from China sad

Tin

They are much smaller than an M2. I would say more like an m1. It is the same size as the one on an extruder gear.

you could always get a new heat-block with set-screw, on eBay.
for about $2.
Sorry, I don't know thread size, but I do have some heater-blocks on order myself,
and could check size when I get them, if you still need it then.
