====== 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)
