As seen in the french section, 3D solex has a new heater block available.

@GR5 do you know what material this is? is it some kind of coating? can't imaging it to be stainless steel... as this has poor heat conductivity?

I could tell you but you asked @gr5...

Yes it's some kind of coating, not stainless steel it wouldn't make sense as you said.

The block is still made of brass but coated (maybe @swordriff could tell us more about it).

[swordriff 119]

It's a multilayer coating with chrome on the outside! - yes inside it is a brass alloy.

steel would be impossible to use, since its thermal properties are horrible.

@swordriff I'm quoting you :

 

We have reached the limit of the UM2+ CPU. With for instance the Bondtech.se - feeder you will print so fast that it starts making square circles.

The CPU itself cannot issue commands fast enough!

Can you give more informations about it ?

[swordriff 119]

SQUARE CIRCLES: when you print much faster than 300mm/sec, the cpu cannot cope- reading all the gcodes and positioning the x/y fast enough- so it starts skipping steps and seems to miss gcode lines..

of course, it is very rare that you have an object which can be usefully printed at such speeds, but they do exist, I guess.

reaching this limit with a stock um2+ is difficult since it cannot melt the plastic fast enough.

What parameters did you use with your bondtech ? 300mm/s sounds crazy...

[swordriff 119]

0.4mm, LH 0.15 , 320mm/sec. And corners are NOT beautiful..
