So i checked all permutations,

the cable works with the provided floppy, but not with the Lotharek, so it must be either the ready signal, or another command
that the qx3 issues to start a read sequence. This signal is never acknowledged by the Lotharek.

this could be diskc,mton or sth else.

the device is connected by a non twisted cable, pin 1 of the fdc connected to pin one of the Lotharek.

i am about to give up....

already answered six months ago : Disk change detection not working -> Bad interface mode, or floppy ribbon wire n°2 broken.
And now i add : bad jumper setting (should be ID0-A+ID3-B here + use my cfg file present on this thread: http://torlus.com/floppy/forum/viewtopi ... 311#p11796) and/or wrong floppy ribbon connection (wrong way like this case : http://torlus.com/floppy/forum/viewtopi ... =28&t=3218).
If you are 100% sure about your connections and jumper settings, enter the embedded hxc menu to clear the eprom and try other pin 02 & pin 34 settings.

Someone else has tested and reported a working setup for the QX3.

viewtopic.php?f=18&t=3595&p=20330#p20330

For record here it is the working setup :

--------------------------------------------------------------------

Specific to the HxC Gotek :

Get a custom firmware with version >= v3.1.60.4a

https://hxc2001.com/custom_fw/

check the "Non gated mode" checkbox,
Set "Motor input line" to "Floppy Select Line".
Set "Motor ON - Ready delay" to 400ms.

Leave all others parameters as default.

Get and update the firmware.
Once your new firmware is flashed you may need to clear the drive internal settings to use some of your default settings : Press the right button at power up to clear them.

NOTE: The stock SD HxC Floppy Emulators firmware is fine. No need to update it.
--------------------------------------------------------------------

The config file (for all SD HxC and Gotek HxC floppy emulators):

-> Start the hxc software,
-> Menu Settings -> SD HxC Floppy Emulator settings
-> In the "SD HxC Emulator Interface setting" set the Drive A config :
Mode=Custom, Pin 2=nDiskChange 1, Pin 34=nReady,
check "Drive B input as Drives Motor ON",
uncheck "2 drives emulation".

If you want to enable the Indexed mode, check "Enable indexed mode"

Save the config file.

--------------------------------------------------------------------

SD HxC rev C/F/Slim switches config : Set ID0-A (1) and ID3-B (8) to ON.

Gotek HxC Jumper config : Place the "MO" jumper, remove all others jumpers.

Attached the pre-built firmware and config files.
