Where can I buy a Janome 11000 programme for my machine

Yes, the upper thread tension on the Jan ome MC 11000 SE can be manually adjusted. To do so, start by loosening the tension dial on the back of the machine until the tension is light enough. Then slowly turn the tension dial back up until you reach the desired tension.

get manual here:

you said it has been in the shop twice do you think that may be they did not check the circuit board out I think it might be in the timing or the board

screen is digital? may need new battery for screen power

Thanks to floraq803, we have our 11000 working again. The needle threader was stuck in the down position. We turned off the machine, and turned the wheel (which controls where the needle is) until the needle threader bar was straight (approximately 1/2 way between the needle being all the way down and all the way up). Turned on the machine and the threader came back up again. Now back to sewing.

I believe there is a new download to make these work with windows 7.

Go here and scroll down to "customizer 11000 v 1.50" or which ever program you have.

High Shank Machines are all the Janome Embroidery models MC 8000, MC 9000, 10000, 10001, 11000, 200E, 300E, 350E....etc
If yours is not an embroidery machine, it has a LOW SHANK .....the higher shank allows for easier access for the embroidery hoop.

When you backed up you probably only backed up documents. The executable files that make the program work are in program files and folks seldom back up program files. It was pre-installed on your pc? How weird. I believe the only thing you can do now is to go buy Customizer 11000. Check ebay and the yahoogroup sewitsforsale to see if there are any used copies. It's not an expensive program, and frankly, you don't NEED it if you have Embird, which does all Customizer does plus more.
