Replacement Cooling Block for Micro Swiss All Metal Hotend Kit for CR-6 SE

I'm really pleased with Microswiss for the way they dealt with a faulty item. Their customer service is top notch and they back their products. I feel assured when I purchase their products for 3D printing.

I'm new to 3d printing. I have a creality cr10 smart, bought used. I upgraded to this hot end because at some point, I want to print other material than pla. Currently, I'm having an issue of clogging when I change filament. I didn't have this problem with the stock hotend, but I'm also pretty new to this. It's hard to know if it's me or the hot end. Aside from that, I purchased the high temp block and titanium heat break to go to 500C. All in all, it works well. Only issue is what I mentioned earlier.

*UPDATE: Once I properly leveled the bed and adjusted my z offset, and ensured the nozzle is cleared out, the printer runs great. We'll chalk it up to operator error. Heats up to 500C without problems (make sure you're thermistor is rated for the high temp.

Quality product...all metal and no problems with fitting and now i have found the brass compression sleeves that came with this hotend i ordered the extruder too! It keeps that PTFE tube in place and much easier to use than the original setup. I was thinking of modding mine to use them then the xmas sale so i had to get the extruder.
