If there is a reset button on your usb drive, then hold it down for a couple of seconds. This may reset the usb, may not be the problem, but works for me.
Also try'Virtual Floppy Software', 3 programs that will format the USB stick (miltiple 720KB, 1.2MB or 1.44MB partitions), Viewer & image writer. Also the machine is fussy about the files - you probably want a really basic 'DST' file (the DST output from PE Design is viewableon my BAS-411) try running your DST file through 'Embroidermodder'I have Goteks in my 416, my 415, and my 423A but to my knowledge the principals behind them are the same. I would assume it has to do with one of the two things below.
Was this in the machine when you purchased it? Reason I ask is because as retarded as this sounds, when I swapped the drives into my machines, I had a similar issue. Ended up finding out that the ribbon cable in the machine has to be plugged in upside down so the notch on the cable isn't aligned with the notch in the drive. This may be Gotek only.
How are you formatting the USB disks? The Gotek drives require me to format the drive using a program called Batch Manage Tool. I have no idea if that program will work for your drive, I would assume Richpeace has their own. Check their website. If not look for Batch Manage Tool 1.4 on google and DL that. It would make a lot of sense to me that since it is just a program to format a USB drive to think it is a Floppy disk, you could use this for your drives also.
God Speed!
I have a 416 that just had the floppy go tits up in the middle of an order. Now that I have to replace it, I was thinking of replacing with the GoTek. Is there a specific jumper setting that needs to be used for the Brother BAS 416 machine? The drive that was removed has the complicated jumper sets on the back and I tried two other drives that took no jumpers and they failed to work.I have Goteks in my 416, my 415, and my 423A but to my knowledge the principals behind them are the same.
