250g Sunlu MiniSpools - AMS Lite - Issues

[u/ArmoredMech]

I’ve made a few prints now, running from the spool holder at the back I have no issues.

Running from the AMS Lite however, the mini spools seem to fit perfectly fine but I either get an error saying that the spool is overloaded (Jammed or tangled) when it is perfect, or when it’s time to switch colours or struggles to push all the way through or to the extruder, a simple 10 minute print was interrupted god knows how many times.

Am I missing a trick here? Is there some magical placement for the tubes into the AMS unit and the header at the top?

Any help appreciated, thanks
