I have a Frister rossmann 504 and the zig zag has sopped working. I can see the needle swing a tiny amount but it only gives a sort of wavy line rather than a proper stitch.
Can anyone help please.

Hello Pat,
The finger is probably not on the camstack properly, you need to take the top off the machine to check, at the very worst the camstack may be cracked and if it is then the machin e would be scrap unfortunately because the cost of repair would far moire than the machine is worth, you can adjust the camstack by undoing the screw on the bottom of the stack and noving it up or down.
