I just (finally) added a Gotek to my main A2000 setup. Now I'm trying to move the Chinon FB-354 that was DF0 in that system to my spare A2000 as DF1, with an identical FB-354 as DF0. I am having no luck to get these drives to work together. I've tried multiple jumper configurations, switching the cable positions, open/closing J301 on the motherboard. I'm not able to locate documentation for the FB-354.
Does anyone have a similar setup that works? My main system has the Gotek as DF0 and a Matsushita as DF1. The Matsushita has a different jumper config than the Chinon, so I can't use that as a reference.
Any help would be greatly appreciated!

I take it you have the required twisted Floppy cable?

I have a twisted floppy cable. Two actually. The original that came with the system and a longer one that I picked up from amigakit. I tried both. Both drives independently work as DF0 on the end cable connector (with the twist) with this jumper configuration (shorted across 5 & 6) as long as there is no drive on the middle (no twist) connector.
1 2 3
o o o
{floppy connector} o ---
4 5 6
Documentation I've found is mixed. Some indicates the pin layout is horizontal, some vertical. I've tried shorting across 4 & 5 and also vertical 2 & 5 to try to set the drive as DS1. Multiple other permutations as well.

Thank you for the follow-up. I did find that post, but links were dead and I was still stuck. Driven by a coffee and OCD, I finally figured out the problem (late) last night. There was a bent pin on the corner of the DF0 drive. The pin was hiding under the cable connector. Crazy that DF0 worked when I disconnected DF1. Here's what I ended up with for two FB-354's:
J301 on A2000 MB: Jumper set
FB-354 on DF0 is at end floppy connector with the twist. Jumper config:
1 2 3
o o o
{floppy connector} o ---
4 5 6
FB-354 on DF1 is on the middle floppy connector with with no twist at the connector. Jumper config:
1 2 3
o o o
{floppy connector} --- o
4 5 6
Lesson: Check every single thing and check it again. Thanks again for the replies. Oddly, I tried this configuration with the Gotek on DF0 and could not get it to work. The Gotek is happy in my main A2K, so that is a problem for another day.
