Servo Motor Mod: Diy Easier Speed Control

[particle]

It really is pretty quiet. I've been using 277 top and bottom, and have bought white, natural, brown and black and most recently Henna from Weaver. I decided to stop offering White because by the time I form, oil and seal, the white thread gets a tad muddy looking and is VERY hard to differentiate between white and natural. So, now I just offer natural. Weaver's 277 natural (It's not really called Natural if memory serves) is a tad darker than what I was buying from Tippmann - it actually has more of a tan color to it. I think my machine came with 3, maybe 4 bobbins. Can't remember off-hand. Thread colors are pretty limited once you start getting up that thick. Some people dye their own thread. I'm not ready to go down that road just yet....

Eric,

Thanks for the info. I'll check with Weaver.

Hello all,

You can add the Consew cs1000 to the list. Works perfectly! Used a hand drawn gradient.

At first: Thanks for still having this great video up on YouTube! Very well done!

I just got my first servo. A Enduro Pro SM645-2P with Positioner.

Regarding this modification, I want ti know whether anybody has done this with a motor with needle positioner? This motor does have tow light paths and it is not possible to offset the light breaker how it is shown in the video.

Cheers

Yes you can modify a needle positioner servo, it is not as easy to do as a standard servor, but not too difficult. Check out the following link for instructions.

Gook Luck!

Great! Thanks for that Link. I have been on this blog, but I did not saw this. I will try this next weekend, if my tow kids give me some free time. How do you like that 645P1 Enduro motor? are you happy with it?

Cheers

So, if I have a clutch motor on my old Brother DB2 B755 am I stuck with what I got?

I shot a little video last night of me sewing one of my pancake holsters using the post-it-note mod shown in my previous post above. What you can't see in this video is that I now have FULL use of the entire range of motion on my foot pedal to control the speed. Granted, with this particular color of paper an the amount of layers I'm using, I can't make full range of the maximum speed of the machine. But, 22-23 (out of 40) is still pretty fast for this type of work - much faster than I need to be using. Honestly, if I was able to utilize the entire speed range from 1-40, the pedal would be twice as sensitive as it is now (with the post-it-note mod installed). So, even though I can't use the full range of speed, the pedal is effectively twice as controllable since it's half as sensitive as it "should" be (to utilize the entire speed range of 1-40 over the same foot pedal range of motion).

Oh my goodness, that's almost like cheating! No wonder my stuff looks awful. What kind of machine is that and what kind of thread was in that video? Beautiful.

Thanks! It's a Cobra Class 4 from http://www.leathermachineco.com/. The thread is 277 Bonded Nylon.

it in responce to post #27

I have almost identical model to the one SWFLholsters have linked in post #28 http://image.made-in...or-CF-400C-.jpg and it has an optical sensor.

Optical slot sensor located inside of the enclosure and control lever interacts with it directly.

In my case this servo works very smooth and has plenty of torque even at 1 stitch per second and i did not need to make any adjustments.

I do not think I can get it to work any better.
