    How old is your Consew?  Does it have a servo motor or older clutch motor?

    I have a 206RB-5 with servo and I installed a 45mm pulley on the motor shaft and it's plenty slow and easy to control.  I have no need for a speed reducer or larger handwheel.  Nor do I notice any jerkiness when starting.  If I ever feel the need for slower sewing than the really quite slow already speed, I just crank the handwheel by hand.  Of course it also takes a bit of practice and experience to be gentle enough with the foot pedal and in the beginning (my first industrial machine) I thought it was way too fast.  Now I usually keep the servo speed several clicks up from the slowest and rarely need slower.

    No offense but are you new to an industrial machine?  And could your machine have a clutch motor instead of a servo?

    I thought I replied earlier from my phone but it didnt go through, or if it did alteast I cant see it.

    No offense taken. I am new to relatively new industrial machines, I am a hobbyist. Its def a servo motor, i installed it myself. My other machine singer 111w has a clutch. I can feather that and sew slow. Idk if its maybe my servo motor (its a cheaper amazon one) its either on or off, it reminds me of my old kx85 dirt bike:lol:. Even if I use my hand to control the motor actuator there is no adjusting the speed other then slowing the speed on the control panel. It isnt to fast on its lowest setting, but I would like to just have more control sometimes, like I can on my clutch motor slowly lower that needle.

    Has anyone found a larger handwheel that fits this machine? I am looking to slow the machine down (i am already on super small pulley, but the mahcine still feels jerky IMO). I cant find much info on what flywheel will fit this machine. I seen some people in other threads have done it, but I couldnt find any info.

    My 206rb-1 seems to be only getting around 4SPI at maximum when the manual says around 2.5 should be maximum. I believe it has something to do with the presser feet timing. I have tried to reset it according to a video I seen on youtube where you loosen the flywheel depending on thickness of material, then lower needle to the material and loosen the 10mm and retighten, but it still seems like it is way shorter then it should be getting. Anyone have any info on how to properly time / set these feet for the lowest maximum stitch per inch?

    I agree.  I used to do all of my printing in ABS because I was concerned about strength but after changing over to PLA I have to say I don't see a difference in strength but PLA is way less problematic to print.

    I'll probably  be switching over to PETG filament as its somewhere between ABS and PLA.

     

    I been printing with PETG, it really isnt that hard. People made it seem like it was goiung to be so much harder then PLA. I basically upped the temp and its pretty damn good. Any idea what size pulley the OP posted is ? Cura is making it huge when I load the STL.

    About a decade ago this was a major problem when the main leather machine companies began shipping digital servos. They started up at between 100 and 200 rpm with nothing between zero and starting speed. Leather Machine Company came up with a clever hack that let the motor start up controllably. It was a piece of clear plastic that was printed with a variable density that was placed between the light source and the photocell. One of those was connected to the speed control lever (I forget which). As the pedal was moved from the off position the density of the filter changed much more gradually than the original light beam shroud. It took a little manipulation to find the right spot to tape it down. Once that was done the motor would slowly speed up and was controllable down to under 1 stitch per second with a 1:3 speed reducer. I installed the filter on the servo motor that shipped with my cb4500 and left it in place for about 3 or 4 years. Then it began developing a dead spot and it had to go. So, I bought an analog servo motor, with a simple knob limiter. It is still on the machine after 6 years and lets me sew as slow as a 10th of 1 stitch per second.

    I have the same motor on a long arm walking foot machine. It has a 2" motor pulley, no reducer, and the balance wheel has a 5 inch diameter pulley. That machine sews as slow as 1/2 stitch per second if I keep my foot steady.

    I have a sailrite monster flywheel onone of my older machines, I wonder if that will fit my 111w

    I recently swapped from my TacSew clutch to a servo motor. I am wondering if there is a way to slow the motor down, I don't mean the RPM - I am using a servo and it drops to 100 RPM, but I mean when I hit the pedal it feels like the motor is either on or off, no real feathering like I could on the clutch motor. I was hoping there would be a way to adjust it so if I lightly hit the pedal the machine would slowly crawl? the TacSew  clutch motor was tuned pretty good and I was able to feather the peddle and get a little needle movement at a time / a single stitch (unless I goofed and hit it to hard) which is kinda what I am hoping to get
