3DSolex PrintCore trouble-shooting anyone else?

[ultradryan 9]

I am having one 3DSolex PrintCore with one UM original core on my UM3, but I am just printing with the 3DSolex Core. I hope this is not a problem.

I bought a 0.25mm nozzle and a nozzle set with 5 other sizes.

First, my 3DSolex PrintCore kept clogging on the 0.25mm EVERLASTnozzle.

I hv changed line-width to 0.25 under finest profile settings with PLA filament.

The print speed is also lowered to 30mm/s.

Next, trying to isolate the problem, I change 3DSolex from 0.25 to a 0.4mm nozzle. So I can compare it to the original 0.4mm UM printCore.

Original 0.4mm UM printCore had been working just fine for weeks now, but when I switch to 3DSolex, under same settings and using same filament, print fails.

The nozzle will be clogged, fail to extrude filaments (printing in the air with nothing),  after the first few layers.

The first few layers looks fine though, but it clogs every single time.

Here are the settings that works well for the original UM printing core:

I tried adjusting the temperature, raising temperature helps a little, but not much.

The same goes to print speed, lowering it to 30mm/s wont prevent clogging after a few layers.

Here are the comparison:

It looks like there's under extrusion before clog, I am not sure about that.

would appreciate if anyone here could offer some help.

I really wanted to get that .25mm nozzle working, but first I think I hv to figure what is wrong with this .4mm core, I suspect it's the same problem.

Appreciate if anyone who are happy with their 3DSolex Print Core could share your experiences... Or should it be the problem becase I am using only one 3DSolex Print Core? and you guys usually buy in pair to get it running?

I really hope to get this fixed...
