Hi
Corona Basement Cleanup ;-)
lots of CNC Stuff around AND a VERY OLD nonfunctional PFAFF sewing Machine
so i always need Batches to sew on Names or Logo this costs 30USD a pice or wait 150+Days from Bangladesh for 5USD

Why not building a Stichmachine myself XY with Digital in to get needle up Sig
lets do it and here is the first test result SMILE



the machine can do only 200stitches per min on a max 15mm steplength in Continues mode
BAD thing it has no Auto Cut off to go from contour to contour but it can do the 90% job i need
AXIS 2.7.11 on ubuntu 12.04 Fujitsu 7111
TB6600 24V China 5Axis BOB
G-code 2D Cad Gcode via Python script Wide and Steplength within MAGIC comment to choose
