V3A extruder, which thermistor in Marlin

Post by 9alfred99 » Tue Apr 25, 2017 5:16 pm

I have acquired an M2 that was unloved. It is actually a pre-production order unit, so it is one of the first. It has the V3A extruder with the wrapped nichrome wire. The previous owner had the Rambo board go bad and acquired a new one, but never used it or even loaded software on it. I have loaded Marlin and it works. But, I don't know which thermistor profile to specify. The only info I can find is it is a "glass bead" thermistor. So, which part number is it?

I'm pretty sure it's #1 in the table.

I also have a handful of V3b components I'd mail you for the cost of shipping.

Thanks for the offer, I' ll keep it in mind. actually I am in the process of converting over to E3D from Reprap Champion.
Already printed the new parts from thingiverse. The big problem I have had is "stringing". Plus, Th ability to use different size nozzles.

Again, thanks for the offer.

For what it's worth, if you stick with PLA or ABS, the V3a is (still!) one of the better performing hotends on the market in 0.50mm size. The long throat allows you to slam ungodly amounts of plastic through it.
