I managed to get a new Pfaff 335 straight from the factory, with a servo motor, couldn't be happier, sews like a beast. But there's two issues. First one is my lack of experience. The manual says I shouldn't be using a needle larger than 69 (or 100 metric) but I doubt it's anything more than a recommendation since the machine can sew through 1cm of vegtan easy. I tried the 69 polyester thread but when I sew 10oz leather straps and belts it's just too thin to look nice. So I took a look at some guides and saw that for that particular oz. (3-4mm) I should use thread size 138-277. Is it safe to use on my machine? Or in other words, would you use any needle you can properly mount or just follow the manual and stick to 69? Saw the same Pfaff 335 in Hermes video and they used at least 2x thicker thread on their watch strap... Anyway, more important issue, my servo. I always read the manual so I'm certain I've used it correctly. Problem is, when I choose the program that should be the slowest one the machine runs like crazy. So I thought maybe it's not the motor, maybe the pedal is too sensitive when it comes to switching between the 'programmed' and 'full speed' modes (press lightly for the former, press all the way for latter). So I always end up sewing by pressing and lifting my foot completely, which is obviously annoying and wrong. Is there a guide for adjusting the pedal sensitivity or something else that might help?

I have a Cobra Class 18 with a speed reducer and Brushless Digital Servo Motor on it. I have sewn on it for a year, now and feel that I am ready to speed up the motor but cannot remember the sequence to program the motor to run faster. Does anyone know how to do this? Thanks in advance. READ MY ANSWER IN THE POST BELOW. HOW TO PROGRAM THE SPEED ON THE DIGITAL SERVO MOTOR.

Hi Everyone So I purchased a Typical DC 20665 heavy duty machine yesterday. The machine really performs great and it is stitching perfectly. The only thing I need some help on is in regards to the motor. At the dealer they had the machine setup with a clutch motor (model: DOL12L, 1/2 HP 4P) which works well. I do actually want to servo motor for the control and energy saving as electricity in South Africa is quite expensive. They then installed a servo motor which I am not sure of the brand but on the label it said 300W - 700W if I remember correctly. With the servo motor the machine would start the first stitch through the really thick layers of leather, so they had to hand crank the first stitch. Due to this they recommended I keep the clutch motor. I unfortunately did not have the time or the patience to stand there and have a long conversation about the whole motor issue so I decided to go the the clutch motor. Now I am thinking that maybe they could have fitted a more powerful servo motor, but I have no idea what the difference is between all the servo motors. Obviously I can call them tomorrow and ask to change the motor for a servo, but what do I actually ask for? Is there a wattage rating or something that I need to look out for? Any advice would be greatly appreciated!

I'm having trouble adjusting the speed on my servo motor I got with my Juki-Lu563. It's a Nick-O Sew model #NKS-4000. [imgur](http://i.imgur.com/hhYJ8L9.png) I can't find a manual for this and Nick-O customer service doesn't seem to have much knowledge of the issue. When I turn it on, the display just reads zeros and then the exterior diodes (idk what they're called) create a rotating circle going clockwise. The servo works, but I can't adjust the speed. pushing the arrows does nothing. When I got the servo, it didn't have a fuse, so I had to replace it, but other than that it seems fine. I would appreciate any help! Thanks,

My 441 clone has an old Ho-Hsing HVP-58 motor on it that I pulled off of another machine. It's got plenty of power, needle positioning, and what seemed like a useful range of adjustments to pickup speed etc. The problem with it is that its low speed setting is still 200spm, which is a bit too fast for me. "No problem!" thinks me, "I'll just put a smaller pulley on it". No such luck. I replaced the 100mm pulley with a 50mm pulley, got a new belt to go between the motor and speed reducer, and tried it out. It runs at exactly the same SPM. The problem is that it's too clever for me. It's not getting its rotational speed from the motor, it's getting it from the NPS unit on the shaft on the machine. In addition to the usual needle-up and down position sense wheels, it also has a speed sensor wheel so the net effect of putting the smaller pulley on is that the machine runs at exactly the same speed but the motor is whirring away much faster. *sigh*. Time to save up for a dumber motor.

I have an old Singer 31k15 Machine that was handed down to me from my grandmother. The machine is is good condition and still sews very well. However the clutch motor in it moves way to fast for detailed leather sewing. I'd like to pick up a servo motor for it, but I can't seem to find any solid info on which I should pick up. I've looked at the Techsew 550 motors, but am not sure how well they'll mate up to the machine I have. Anyone have any recommended motors they've used on the 31k15's, including where to get them. What modifications did you have to make to install it? I'm using fairly thick leathers so I'll need something with decent power, and I'd prefer something that can run very slowly with high tq. Any input would be appreciated! Josh

Decided to change some things up here and getting rid of a few machines. With these 3 machine you can cover all of your sewing needs. First up is a Cobra class 3 that includes a few pounds of thread, some needles and the heavy duty roller edge guide. Comes on the standard table with servo motor. Asking $1600 for it. Next up is a Highlead 618 walking foot machine. Will include several packs of needles, some 1/2 pound spools of thread, lots of bobbins and several feet. Have a extra bobbin casing and extra set of feed dogs. Machine is mounted on a table with servo motor and thread rack. Asking $875 for it. Last is a Singer 31-19. It is mounted is a long table with servo motor. Comes with a ton of needles and silicone pots. Asking $200 for it. All machines are located in Southern Indiana. Willing to drive a few hours to deliver for a slight fee to cover gas. Otherwise these are for pickup only. Shipped only if you arrange for packing, pickup and shipping.

Hi, can anyone here help advise me in regards to which is a good quality servo motor. Sewpro, Enduro, Sewquiet, etc. I plan to use it on a singer 51W55. I would like to be able to sew 1/4'' thick leather slowly. Thanks a lot

Hi, I just acquired a Consew 206rb-1. I paid $500 for the head, motor, and table, and it works great. However, I need more control. I am looking for some suggestions for a good servo motor that will work with this machine. I'm a school teacher so it can't cost an arm and a leg . Thanks.

I have an Adler 867 coming very soon. Can anyone recommend the best motor to put on this machine? It currently has a clutch motor attached. I have a Juki dsu-145 that has a reliable 5000 on it. (Not yet modified like I have read on forum.) It's ok...just looking for something better. Thanks in advance! Also I see the 867 has a pressor foot lift of 20mm. Should that be enough to sew my collars that are at max 5/8 inch thick? Note: a 1/4" of thickness is padding. So, its not like sewing thru 5/8 of all leather.
