Conect 121 Lathe - The toy collection grows!

[m_c]

Spindle index sensor has now been connected, which has allowed me to adjust the spindle settings so the requested speed is more akin to the actual speed.

Prior to connecting the KBIC to the C23, I adjusted the spindle settings so that the C23 was giving 7V at full speed, as per the KBIC manual for voltage following mode. However, upon setting up the spindle sensor, I was only getting about 1500RPM at full speed, so gradually increased settings until the C23 was outputting 10V, which at the commanded speed of 2100rpm, was giving a true speed of 2069rpm.

I've also got the coolant misting solenoid wired in, but need to get a couple swivel elbows and some new air pipe to get rid of kinks in the pipe work.


Next I need to think about homing/limit switches, and what buttons I want on the front panel.

Ideally I think I'd like to add a Pokeys system and design a completely new control panel, but for now until I get some use out the lathe and figure out what will be good to have, I'm thinking I'll just wire up the existing jog buttons, and the solitary 'feed rate' button as a feed hold. The spindle control stuff I'll just ignore, as that's all controlled via Mach.
