====== Juki DLN-415-2 Industrial Sewing Machine ====== ====== Ask Jacob for training ====== HIGH SPEED, SINGLE NEEDLE, NEEDLE FEED.\\ LOCKSTITCH INDUSTRIAL SEWING MACHINE\\ EQUIPPED WITH AN AUTOMATIC UNDERTRIMMER\\ Owner: Jacob\\ Location: G14\\ State: Functioning, but lacks proper access control/bells and whistles ==== To-do list! ==== * Reassemble * Fully clean * Get missing screws for Feed Dog (Potentially feed dog cover screws too) * Feed Dog - Screw 1/8-44 L=6.4 * 2 * Feed Dog Cover - Screw 11/64-40 L=8 .5 * 2 * Get new oil * Build new spool holder (Spool rack too) * Learn to use + write documentation ==== Ideas for future ==== * Access control, for safety + training reasons' * We need new boards, however we may need a bigger relay as the standard ones are 10A, and the machine can run up to 13A * Modern speed controller for motor * The type of motor we have is a [[https://en.wikipedia.org/wiki/AC_motor#Permanent-split_capacitor_motor|Permanent Split Capacitor motor]] so we'd need a VFD for best control, a voltage divider could work too but not as well. **Not needed, but instead I should adjust the motor so it's easier to run at slow speeds** * Motor brake * In theory not needed, as the machine only operates when the belt is engaged with the motor, but the motor does keep spinning for a while when off. * Reverse engineer snipping mechanism * I'm pretty sure it's just an actuator, and I think the wires are broken out? It //should// be as simple as sending some juice down the line. We should map that to a button instead of the intended mechanism (Full pedal press) ==== Documents ==== Manual -> {{ ::ddl5522.pdf |}}\\ Usage Manual -> {{ ::juki_dln-415_better_usage_manual.pdf |}}\\ Parts List -> {{ ::juki_dln-415-partslist.pdf |}}
