We spent a good few hours with the Brother machine today & noted a few things whilst using:
- the automatic threader sticks in an in-turned position, obstructing the travel of the needle arm. This can be clicked back into place but it looks like there is a torsion spring that has come loose
- the needle dislodged from the holder multiple times throughout our use, whilst tightened well, on a low tension with a low weight fabric - i’m wondering if the tip of the locking screw might just need a little roughing up to increase the friction between it and the needle shaft?
- the bobbin carriage is not rotating freely all the time, meaning the lower thread isn’t always pulled up when threading, and at one point was actually obstructing the needle in its lowest position
TLDR - I think the machine may need a little TLC as everything was working nice and smoothly a few months ago. I’m very happy to give it a bit more time to try to get it back in ship-shape but this would be learning on the job so am a bit apprehensive with an expensive bit of kit!
