Like Marji said it can't be influenced by the digitiser.
The machine usually slows down when the pantograph has to make large movements and goes as fast as the top speed you've set when the hoop has to be moved over smaller distances. I just stitched out a butterfly and the machine stitched at a nice and steady speed until it had to do the wide satin stitch for the body.
Speaking of wide satin stitches - the maximum width for those slightly differs for various brands of machines, up to some 12 mm or so, and that is something a digitiser has to take into account as the digitizing software may have other limits.
Logically, there have to be speed changes. The needle just goes up and down, it's the embroidery arm holding the hoop that changes it's direction and location. So, straight stitching will be faster than a zig zag, and up/down/ or side to side movements will change the speed.
You can set the speed on your embroidery machine, which means that the speed you set is the fastest it will go. The digitizer can't control the speed at which the design sews out, that's not part of the digitizing process. But your machine knows when it's sewing out certain kinds of stitches, and will slow down as it needs to in order to do the stitch properly and not "trip over its own feet" so to speak. I'm just always amazed what these smart machines "know", their little computer brains are amazing! Hope this clears it up for all of you, hugs, Marji
I have been wondering the same thing. I have noticed a few times that my machine has increased its speed suddenly while stitching an embroidery design which was going slower up to that point. Sometimes thIs sudden speed increase creates a problem, is there something we can do to avoid this happening? My machine is a Husqvarna-Viking Topaz 30.

It seems to me, on very good designs is when I notice it, it's like it won't let you go full speed ahead when it's a delicate spot. I don't digitize, so I don't know.
Lidiad, as I said above, the type of stitches actually dictate the speed of the machine. I have had that problem with some designs, they are doing a complicated area slow, and then come to a strait running stitch and go 60 miles an hour! One thing I have tried is to slow the machine itself down. Since it's already doing one part slow, that part can't really get any slower. But if you make the "top speed" slower, then it might not go so fast when it comes to the easier part of the design and speeds up. It will still speed up, but if you have the machine at a slower speed, it won't speed up so fast. I hope you got that. Good luck, hugs, Marji
Sewing speed is controlled by your embroidery machine...there are usually settings to set the number of stitches per minute...my Ellisimo has settings from 350 to 1000 stitch per minute...depending upon the design and the thread, etc., you set the speed.
Yes, I know that, mine has several speeds that way also. But it seems to me that some designs slow down and speed up on their own in different parts of the design. Maybe it's my imagination!
I don't think it's your imagination "bowlds" as it happens to me too. Love Chris
I think it is the type of stitches it is doing. If the stitches are short it is faster but the long stitches take longer to cover the space.
I stop my machine when it does this and slow it down till i am happy. I have found that a suddern change of speed can cause the needle to break when embroidery on thicker projects.
