Hi Alex! Sounds like an interesting thing to do :) Do you need full control over the needle (i.e. coordinated moves), or do you want to let the needle be driven by a single motor in continuous motion and synchronize the X/Y movements to it? In the latter case, you would only need position

Hi Philipp . You point to the right direction. I need a full control over the needle movement because I have to start the X-Y movement before the needle is at top position . This is mainly related to the speed needed for the sewing cycle . As early the enable for X-Y movement is triggered as fast
