All ERCT Coupler_Block_xxx versions have a design flaw in my testing. When a spool ends and the filament has a kink, it is capable of pulling the ptfe tube with it.
The Coupler_Block_xxx should have a built in bowden tube stopper. My solution for now is a reverse ecas with lock clip so it cannot depress and let the ptfe tube slide inwards.
Second issue is that the filament that was reversed managed to get exactly into the ERCT arm holes and get stuck. That zone of the arm should be solid, without any holes or the Coupler_Block entrance re designed so that situation would be impossible to happen.
The RC2 Coupler_Block_xxx entrance does not help inserting the filament. In reality it's still a pain in the ass to insert the filament. If it had a little extension downwards, the insertion would be easier and that sharp turn impossible to happen.
EDIT: expect maybe the Coupler_Block_Lite version ?? but that seams unpractical... Nope..
I reported this on discord https://discord.com/channels/460117602945990666/909743915475816458/1245146439353372752
But I'll repeat the post here.
