Juki 2010q makes 2-3 stitches after I let off the pedal or press needle down button

[The_Last_Unicorn]

I haven't sewn in a few weeks. I oiled the machine and turned it on to do a small project, but I noticed the machine is taking longer to stop sewing. It used to simply complete the last stitch or one more stitch. Now, if I let off the pedal, the machine makes 2-3 full stitches before it finally stops. The same thing happens if I press the needle up/down button. Has anyone had this happen before?

I have the Juki 98E, but I've not seen a lag in stopping. That has got to be frustrating.

My only suggestion is to unplug your foot pedal and clean it. Of course, a foot pedal problem wouldn't explain the "needle up/down" problem. Perhaps some fuzz is "upsetting" the internal wiring.

Oh no. Now it's even weirder. The needle up/down button now randomly decided whether the needle ends up or down. Same with regular stitching - might end with needle down or needle up. The cut thread button just makes the machine make a few stitches, and doesn't cut the thread at all.

Edit: gonna try and give it a thorough cleaning. I'll make some calls to Juki and/or a repairman tomorrow to see what's up.

It may be something with the foot pedal. My older machine did something like that and it was the connection in the foot pedal.

Keep us posted. I think giving your Juki a good cleaning may fix the problem. It's a mechanical machine, so dust bunnies in the wrong places can wreak havoc.

Actually this machine is not a fully "mechanical" machine. It's missing some functions of what we consider to be "sewing computers," but some of the functions and features are controlled electronically. The only thing missing really is the control of more than a straight stitch. We tend to think of "straight stitch machines" as being mechanical.

The speed control, needle up/down, thread cutter and foot pedal are all electronic controls with circuit boards, sensors and stepper motors to perform these tasks. Who knows where the problem lies, but the symptoms mentioned are most likely the result of a failing electronic component. Leave it to the Jukiman.

I hope it's fairly new because Juki only warrants electronic components on these for two years.

Thank you for explaining this! You've answered some nagging questions I've had about the Juki. What you've said makes complete sense and answers my questions. I apologize for my mis-statements.

Last night, I emailed the online store that I bought the machine from. I got a call from one of their technicians this morning and he let me know that my machine is still under warranty (yay 5 year extended warranty!) and that it does sound like a problem with an electronic component. Glad I saved the original box, because I'm going to send off my dear Princess Juki to be repaired.

In the meantime, I'm going to be using my backup machine, a Brother cs6000i. I won't be FMQing anything larger than a pot holder, but I'll still be able to piece and applique.

I'll update this thread as I get more info about the repairs. Maybe it will be useful to someone who has the same problem in the future.

I'm so glad to hear that you are still under warranty! You must feel quite relieved.

Yes, please do post an update. I'd love to hear what happens.

I heard back from the technician that it was the motherboard all along. I asked what seemed to have caused the malfunction, and he said it may have been that I oiled the machine a little too much, and some of the oil got on the motherboard. Also, they just sometimes go bad. Everything is fixed now and it's already on its way back to me.

When and how much to oil the Juki 2010 has always been a little confusing. According to the manual, you do a few drops in each oil hole after every 8hrs of sewing time. Back when I did that, excess oil would seep through the buttons and the rubber feet on the bottom of the machine. I scaled back to one drop or maybe two instead, but it seems like that was also too much. I must have been oiling too often in the end. It's harder to quantify sewing time when it comes to piecing because I stop to cut apart and press my units.

I oil mine every three bobbins. Normally just one drop per hole.

Bubba - I'm going to try that from now on. Do you use the Juki Defrix oil #1, or a different brand of machine oil?

My Juki is already returned home. It's in perfect working order! What a relief. I bought the machine from Sew Vac Direct. Honoring the warranty and getting the repairs done through them was quick and hassle-free. I'd definitely recommend them if you're looking into buying a machine online

Glad your machine is fixed & working wonderfully now. My first Viking went out just a few days from the 5 yr. warranty period. It was the mother board. The LQS replaced it at no charge. Whew, saved by the bell! I was instructed when I bought my Vikings to never oil them. I do use the machine oil for my Baby Lock Tiara II table LA. Very sparingly, maybe every 3rd bobbin.
