V-Core Pro lives again (-:

@Corexy Yes sh*t loads of problems - take a look at my blog. But I'm only using Mosquito heat breaks - everything else is home made (it's a 6 input, single nozzle) - and it's "everything else" that I've had problems with.

The heat breaks themselves are super efficient and tiny compared to anything else - (really important when you are trying to get six of them into hot block).

I did use the Boron Nitride paste but only because they supplied it to me F.O.C.. TBH, I use Loctite LB8065 on heaters and cartridges so I'd probably have used that instead if I hadn't been supplied Boron Nitride. Technically they are both release agents but they both work as high temperature thermal paste. Boron Nitride is better around heater and thermistor cartridges because (I'm told) it's a good thermal conductor but a very poor electrical conductor.

One handed nozzle change is doddle and makes life a hell of a lot easier if you are in the habit of changing nozzles.

I can vouch for that, because 40+ years ago I used to make waveguide CO2 lasers out of it. CO2 lasers require an electrical discharge through a gas mixture, but that gas mixture must be kept cool or the laser doesn't work. So I needed high thermal conductivity to allow a water cooled heatsink to carry the heat from the discharge away - and good electrical insulation to contain the discharge.

No worries,

Any updates on the v-core?

I'm planning a bit of a new/minimalist approach to the 3 point bed leveling on mine.

I fixed the heater block orientation and shortened the heater cartridge cable. I printed the part cooler from the tool changer set and am waiting for the 4010 radial blowers to arrive.

Im using the BMG Mosquito with a Magnum on my VCore Pro. @Corexy

I am still hunting for a durable surface that would work with IR-probe.
I have some black copy of Buildtack, but it holds too much and even a slight hit with hot hotend runis the surface.

But the V-Core pro is great!

And Bl-Touch is not an option? @OBELIKS

OBELIKS

Maybe, with a different cable. It would need to be shielded

@OBELIKS mamorubot PP plate works well for me.
