EllaNis Report post Posted December 8, 2020 Hello all, Could anybody clarify to me if the stitches are correct on this PFAFF 1245, please? It is the first time for me when I use an industrial machine, I bought it second hand, imported from Germany. I have no experience with this very powerful and high speed sewing machine, but I am determined to learn to use it . Here are some pictures with the machine and the stitches. In my opinion, they are not right. I would like to have the straight stitches. Can you please advise me what to adjust, if this is needed? The second concern of mine is the speed, omg, it flies!! Related to the speed reduction, I read some posts in this great forum that there are also servo motors that could reduce the speed. Is there any other simpler solution, beside "feathering" the clutch pedal (as I read in one post) and replacing the motor, to slow it down? Thank you in advance!

Sonydaze Report post Posted December 10, 2020 It looks like you have a LR needle in it. The LR needles cut the hole on an angle to cause the zig zag look. Change the needle to a dia point and you should get straight stitches. Quote Share this post Link to post Share on other sites
SEWTRONIX Report post Posted December 10, 2020 I made a custom table to test all sewing heads and got the table and motor from Weaver Leather. A servo motor will do you good on speed control. Needles and presser feet should give you varied stitches. Try changing those out. I tell customers to change the feed dogs, throat plate, and presser feet after 200 hours of operation.

Constabulary Report post Posted December 11, 2020 (edited) how many RPM makes the motor - 1400 or 2800 I guess. If 2800 thats super fast and I would not even try to modify the motor. I´d buy a servo motor and if you want it even more comfortable I´d add a speed reducer as well. Reg. stitches - I´d try an S-Point needle Check the attached file. It gives you an idea of seam appearances when using different needle points.

Pintodeluxe Report post Posted December 11, 2020 I agree the type of needle makes a difference how the stitches look. Also make sure the needle is inserted correctly. The eye of the needle should be oriented true left-to-right (not diagonally). Good luck with it! Quote Share this post Link to post Share on other sites
