FlowTech™ Hotend for Bambu Lab X1 and P1 Printers

I was really looking forward to using my Flowtech hotend in my Bambu Labs printer farm and in my other printers (Voron's). I ordered an initial Flowtech hotend for a P1S along with several different CHT and Hyper CHT nozzles. As soon as mine arrived I was a little concerned because it did not arrive with a sock. I mounted it in my P1S while a waited for a few packs on socks for it to arrive.
The sock's for my Flowtech arrived a few days later. I put the sock on and tried calibrating but it wasnt printing as well as I thought it should. I ended up swapping out my .4 nozzle it came with to a .6 Hyper CHT nozzle using the printed torque tool which came with the hotend. I was a bit concerned through because it didnt feel like it the little plastic tool was tightening the nozzle enough. I tried printing a speed test, I hit start and by the time I stopped the print enough filament had squeezed out of the hotend block that it had ripped through the sock and had embedded filament into the plastic toolhead cover and destroyed the extruder.

I have witted to MicroSwiss support but have received no response, while I am out of pocket a few hundred dollars for the hotend and the nozzles I cant use, as well as another $250 for all of the replacement parts the hotend destroyed. I hope MicroSwiss support gets back to me at some point or I am just out $520.00 USD because printing a plastic torque wrench may save money but in the end it throws so many variables (what temp are you using the tool, what temp has the tool been through to get to you, ect..) that this sort of thing is going to happen to a lot more people..

If you are actually looking at these MicroSwiss I have sent you pictures and requests for help - it would be really nice if someone could respond.

It is doing great. It is part of some upgrades that I have done to my printer mostly around the filament head area. I am having nothing but great results with all my prints.

I got my hotend on the 8th it was printing ok for a day or two. Had some failed prints then it had a complete failed print with filament all around the heat core and nozzle was melted in stuck

No matter what I tried I can’t get this to print without error. It either throws errors to do with heat or fan or something else. Often it won’t even start the print, if
it does it eventually fails. I’ve gone through and
changed so many setting with the help of articles, their website and using AI, I change back to the Bambu nozzle that I replaced and no problem. I really want the Micro Swiss to work, I love the features and hate changing tha Bambu hot end. I’ve tried more than 1 Micro Swiss hot end as I order replacements and no difference. I’m at a loss and really I think they could do a much better job of explaining if and how to set up your slicer setting differently, this has been tough to understand for sure. There is likely some user error here, but if I can’t figure it out, I wk def how many others struggle with it. The cuple hundred dollars is sitting in a drawer.

Clogged on first use, never worked once. Save your money.
