Just got my new Consew 206 rb5.
Very nice machine but the servo motor is very sensitive.

My issue is there is about 1/16 -1/8" between 0 and too fast.
Are they all this way?
Ive seen videos of people stitching so slow and smooth which is a big part of why I went this route.

What can I do to slow this thing down?

I can back it down once I get going but there is no way I could sew anything but a straight line as is.

Its the Consew 550 motor

[Kra z Bill]

what is the speed set on??? turn the speed down. to it's slowest setting.

[IvanD]

Install 45mm pulley on motor. This is cheap motor, doesn’t start slow, not enough power

[miket]

Bill, it is same on all settings. Only difference is top speed.

Ivan, it has a 75mm on there now. I figured a pulley change would slow it down. I assume a new belt also.

Whats a good motor that gives you control to go stitch by stitch?

I have no issue upgrading and selling this one.
I want this machine to work flawlesly.
I am a newbie so the slower more controlled the better.

[BigRig]

@miket , It is possible you have a flawed motor. It sound like it is getting too much juice.

[miket]

Not sure bigrig.
Its my 1st servo.
Im gonna call the dealer tomorrow and see what they say.
Been googling quit a bit and it looks like smaller pulley or speed reducer will take care of it hopefully.

[Revv Up]

Shouldn’t need to change pulleys, sounds like something’s wrong with the motor or the controller.

[IvanD]

Smaller pulley will make a lot of difference for sure. Then, practice will make even more difference. For upholstery you do want to go faster, not stitch by stitch. You can always just crank by hand if you need it very slow.

I got this one (link doesn't open at the moment)

It's powerful, very good control, they come with 50mm pulley already and have needle positioner which is very handly

[miket]

I do mostly marine canvas and binding on inside curves is still tricky for me so I need to go slow and be able to maintain a consistent speed. It takes both hands to feed the assembly so I need to be able to maintain speed control with my foot.

I totally agree I need more practice also.

Gonna try pulley 1st since its the cheapest and easiest and may be all I need.

Thanks for the link

That isn't normal. That motor should be able to crawl stitch by stitch. Have you adjusted the speed control knob on the front of the motor?

[miket]

John,
I have adjusted the speed control knob.
It is not a dial type where you can fine tune it.
It has settings and it clicks into place at each setting.

The machine was set up by the seller and tested so I guess something could have happened in shipping but everything looked fine.
Not sure what is going on. It works greay everywhere except down real low.

@John

I spoke with the dealer who sold it to me and set it up.

He said being new the machine is tight and will loosen up over time which will make it smoother.

That and what Ivan said about it being a cheap, weaker motor make sense to me.

He also said a 45mm pulley will help.

Of course noone has a 45mm pulleybut I did find a 50mm so I am hoping this will fix my issue.

[Revv Up]

On my both of my controllers I’m able to dial the speed down, does yours allow you to slow it down there.

[miket]

This is the one I have

I had the same issue with the motor that came with the Juki machine I bought new. If you turned the motor down it wouldn't start and the pedal was more of a on off switch than a pedal. I ended up switching pulleys and it helped some but still wasn't how I wanted the machine to operate. Ended up purchasing this

It has a digital speed readout instead of a dial. I'm much happier with this motor. I'm still considering putting a speed reducer on, I actually have one sitting ready to go on but as heavy as it is I'm curious if the motor will be able to stop it on command or if I need to put it on my lathe and take some weight out of it first. Sometimes is take a little trial and error to get your machine to operate how you feel comfortable operating it.

@SmokinSCustoms
Thanks for the reply
Are you able to dial that motor down to sew stitch by stitch?

Why are you considering a speed reducer on it?

I have ordered a 50mm pulley to see if that helps.

[Kustomizer]

I have an older SewQuiet 5000 and can go stitch by stitch. Here is the newer one. https://reliablecorporation.com/product ... servomotor

I guess it depends on your definition of "stitch by stitch" I wish there was an easy way to upload video's on here to show exactly the speed I'm talking about. You can "bump" the pedal and it will pretty much turn the machine 1 full stroke. I'm still considering the reducer just due to the fact the motor has a lot more speed in it and if the reducer was on the machine I would have a lot more range to work with as I could always let the motor run faster. Electric motors really like to run wide open anyways, when you start restricting them with resistors they generate heat and loose efficiency. At least that's what I've always been told.

You may want to try another machine at your dealer that uses that same servo motor and see how it is at the low speeds compared to yours. I don't buy the dealer's explanation that it's a machine breakin issue unless your machine is super stiff or something and the motor is trying to generate a lot of torque initially to overcome that. On some of these older servos, they are using an optical sensor on the pedal lever which has poor sensitivity between full on and full off. Some people have modified them changing the interrupter blade that interrupts the sensor to produce a better gradient on the low speed settings. You can find that online in some other forums. I've done that on the full digital consew servo motor and it really helped. The newer consew servos seemed to have improved that speed control. If you don't want to tinker, maybe try the Consew CS1000: https://www.amazon.com/Genuine-CSM1000- ... HCVAAWK0D5
