Need software for a Singer Futura XL400

needle tension not tight enough

There is very little posted about error E10, except this. It indicates the machine is broken.

My Singer XL400 gives me error 10 saying the hoop size is wrong no matter...

FWIW, there are a lot of complaints about this particular model. Hopefully, it is still under warranty...
...

If it's new, take it back immediately! You'll end up with it in the shop more than your home. Go to a local sewing machine dealer with a repair shop. They can tell you which brands are reliable, and will fit your needs.

bobbin thread is too high pressure or too low pressure on teh top adjustment!

remove bobbin and turn tension screw about 1/8turn left (anticlockwise) check if still grabbing, if so - top thread turn about 1/4 turn (at embroidery ir should do automatically, but sometimes need kick...).

check if it is still grabbing on the bottom, do it grab during straight? zigzag? double zigzag? if do not - setting on the pattern need to be look at. if it tangle as well on these three - need definitely servicing...

follow manual how to adjust.

I owned an XL-400, and now own an XL-550 and Quintet, which all run on the same software. Could you be more specific about the problem you're having?

I have a feeling that you received the basic Futura software, as well as a second CD with the add-on software like AutoPunch, and THAT software refuses to install, giving you a message that the basic Futura software hasn't been installed. It has, but XP has not yet installed the drivers into Windows. What you need to do is after installing the basic Software, you need to plug the machine into the computer and turn it on. You will get a message, "Installing new Hardware." Bring up the Futura program once and then close it, and NOW you will be able to install the add-on software.

Before any Singer Futura embroidery software will open, your machine must be on and connected by USB cable to the PC. It serves as a dongle. Many high-end programs require that a USB plug called a dongle be inserted before their program will open; connecting the PC serves as a substitute for that.

I don't why you need a patch for Win 7; the software was created for and works on Windows XP, Win 7 and Win 8 without alteration. However, there IS an update patch available at the Futura support site, www.futura-support.com. Click the My Machine model link at the top, select your machine, and then select Software on the left, and you can download the patch.

check the wattage on device and on converter if compatible and capable

You did not indicate which operating system is used on your laptop. If you have Win Vista, 7, or 8, there is a patch that you can download from singerco.com, find your XL400, go to software and download the patch (should go to your download folder) . Next go to the Control Panel and uninstall the software. Re start your computer. Turn OFF your anti virus software and install the Base Singer software. Next, go to the download folder and double click on the Futura patch. Plug in your usb to the singer, then laptop, and turn on the sewing machine. At this point you can Launch the Futura software.
1. Turn on Computer
2. Plug in usb from XL 400
3. Turn on XL
4. Launch Software
Hope this helps - 8)
