My Janome memory craft model 9000 sewing machine is now sewing at one slow speed. The quality of the stitch is good but too slow what should I look for?


Your speed slide sensor is bad. Your local repair shop can fix it. There is a chance it's the foot pedal. If it's still slow when you sew without your pedal, then it's the sensor.

Brother pe-770 f05 speed sensor error - How to fix?


F05 error, speed sensor. I fixed successfully 2 of those. Speed sensor is located on a small board, under a protective plastic, located over the main front board. Remove front panel and bobin winder assembly. Remove the 2 screws of the small board. Remve CAREFULLY the small bord. Under, on the main shaft, are located the needle positionning sensors and the wheel of the speed sensor (left wheel on the shaft). The speed sensor is located on the board itself, it's very small. Clean carefully both the wheel and the sensor with Q-Tips and alchool, reassemble the whole thing and it should restart.
While U are there, take a thin nozzle oiler and lubrificate all the suppots of upper and lower shaft, all the needle bar mechanism and rotary hook central shaft and gears WITH VERY THICK oil. Needle bas assembly is the most critical point. I have 14 of those machines, almost all of those seized there before I learn how to lubrificate it. Also seized on the bottom shaft and on rotary hook pin

How to oil brother PE 770


Brother says it should not be oiled but having 14 of those, I know that it has to be done but a Brother technician will not do that. OILING the machine may cause F05 speed sensor error. See how to solve it under this label.

U need to remove the complete front plastic panel. 3 screws on the top (2 lower the handles, 1 at upper right. Remove 1 screw at the center bottom of the rear panel. Remove both left top/ bottom panels (1 screw each) then the horizontal bottom left panle (2 screws). All the balance is fixed with clips.

First undo the 2 clips under the machine than carefully unclip everywhere. Front panel have 2 wire assembly attached to main board. Regular one is easy to remove. To remove the flat one, send down the upper part of the attchment on the main board.

Don't use reg. thin white sewing machine oil, it evaporate. Use SAE 80 (differentail type) oil or something like taht. Lubrificate all 4 lower shaft supports, rotary hook gears and central pin (from the top, under the bobbin case). Then lubrificate all the upper shaf support and especially all the needle bar mechanism. U need a good light to see upper needle bar support. Lower needle bar support support is the most critical point.

I have a Brother PE 770. All was well, fairly new machine and whipped stitches out correctly. All of a sudden it is shredding the top thread and it almost seems the bobbin is not catching. Would this be...


here are some suggestions to try
it's may be the needle, it could be bent or blunt

it is possible that it could be the timing,,,, but first try changing the needle & try rethreading the
machine the top thread & bobbin also

make sure the bobbin is in the bobbin case correctly & that the bobbin case is correctly inserted into the machine correctly

check to see if there are any burrs on the needle plate
clean out from under the needle plate
also make sure the bobbin area is clean from lint or loose threads

I have a Singer Futura CE-150 and it keeps stopping due to "Thread break error" but the thread and bobbin seem okay what could it be?


Either upper thread is not passing through thread sensor area or sensor is broken.
Second possible reason is that if design is not optimized the sporadic speed change provides thread breakage error even if the thread is not broken physically. Make sure your software is updated to optimize it automatically (Futura main menu->Help->Live Update).

My emroidery carrage reads the wrong hoop i have done every thing the manual says to do but it still tells me the small hoop is in when


When using either hoop you should place the frame on the carriage before you send across the design as there's a sensor in the carriage. Also when you send across the design and it asks you if you want the design optimised for speed you must always say YES. If this doesn't work then i suggest sending the machine to your local agent as the sensors may be faulty.
