Re:Hardinge CHNC 1 Lathe

Hi Dan,

I'm not there yet, It is all moving but I need to work on the PID tuning and figure out what I need to look at on Hal Scope.

I'm closer than I've ever been.

The X axis belt came in today so I got that up and running and homing so things are progressing nicely.

Well I made some good progress this morning and have the tool turret up and going.

I've attached my ladder file for those interested in how I did the ladder logic.

SWEET! I actually made some chips on the Hardinge last night. It's not ready to run completely but close.

I've made a lot of progress on the CHNC and have made a few parts and some not so good parts as a learning experience. While scrounging through a machine graveyard I found a control panel with a bunch of AB selector switches in it. To my suprise there were three 4-position selectors. I installed them near the MPG and used the original legend plates even though I don't have a Y axis... this setup works so much better for quickly moving the turret to a touch off position. The only thing that does not work in this photo is the Feed Override Knob as it is a binary type and I can't figure out how to use that with EMC2. It sure would be nice to have it working...

Hello John, what do yuo mean when you say this
"The only thing that does not work in this photo is the Feed Override Knob as it is a binary type and I can't figure out how to use that with EMC2".
Is the Feed Override Knob digitally coded in BCD or GRAY ?
If is coded as I say maybe you can decode it with ClassicLadder and manipulate the value for the use into an hal file,
