The A10M hot end setup ...

[millenium7]

I hate this stupid nozzle setup for a number of reasons.
- It oozes horribly - as bad as my Volcano setup with a 0.8mm on it. Always have to grab multiple blobs and strands between prints
- Despite lots of oozing, there's a huge amount of resistance in the hot end, resulting in stripped filament and clogs
- Proprietary nozzle....... WHY!? Makes zero sense, I want to use 0.6mm or 0.8mm nozzles
- Huge pain to remove and clean
- Replaced the stock one with a new one from Geeetech, still sucks

I'm yet to print a single dual colour object on this printer, my first nozzle clogged really easily, it was a massive pain to pull it apart due to the design, I clean it all out and try again, again it just clogs on one of the hot ends. So I printed with it on just 1 extruder for a while, quality was pretty average due to under extrusion - the extruder gear would slip every so often
So I bought 2x Trianglelab BMG knockoff extruders to massively up the driving force. Problem is the stupid nozzle design has so much resistance that now instead of slipping i'm just stripping filament

Now I notice there is a little filter/strainer in each hot end, can I simply remove that? That would massive reduce the resistance
If I can't find a magic pill for this damn hot end i'm gonna throw it in the bin and run 2x E3D V6 clones with a traditional dual extruder setup instead. This is way too much hassle, more than a month and not a single print to show for it

Do you have a link to other nozzles that work with this hot end? 0.4mm is way too small for me, I want to be able to print large scale objects with embedded text, quality is nowhere near as important as speed in my case

As for the hotend being utter garbage, i've made some progress. I noticed there were plugs of plastic in both hot ends, the included PTFE tube is ever so slightly too large and wasn't seating fully. Removed the plugs by heating up an allen key, holding it in place for a minute then pulling the plugs out until I got solid metal to metal contact. Replaced the PTFE tubes with new ones.
Still stripping filament and getting jams though. Trying to print the included lizard is impossible, both nozzles jam. I'm using regular PLA and even upped it from the preset of 195c to 205c, no good. So now i'm printing at 250c instead and it's working

I rolled my own firmware from stock and built it up. I'm wondering if 250c on the printer is actually closer to about 200c in reality, maybe the thermister value is wrong? I'm using a value of '1' in Marlin 1.1.9 is that the correct value for this thermister?

NOPE! Even after cleaning the hot end yet again, ensuring I have a perfectly flush PTFE tube and PLA at 250c the stupid thing still jams halfway through printing the test lizard. Total crap setup, gonna throw it in the bin. Not worth the cost in time and mental sanity. I wish I never bought this printer

oozing and stringing is terrible and I cant find a solution
