Hardinge CHNC II+ Hickory LeadShine EL7 Retrofit

Not quite right, but if you do not have a jog panel pendant or console, and you never use the keyboard jog equivalents, then your fix will work just fine.

I would have swapped SkinJogAx2Plus_M_SV and SkinJogAx2Minus_M_SV between the two lines, so that the upward-pointing jog buttons in all three contexts do a minus jog, and the downward-pointing jog buttons in all three contexts do a plus jog.

Once I have set home using M26/X/Z can I just use a G28 to return there without messing up my home setting.

Yes. G28 just moves the axes to the designated location, relative to the already-set machine zero. G28 does not change your machine zero.

Thanks Mark, I do have a wireless MPG if that will make a difference.

I saved a copy of the original, so would I need to go back to that original version and just swapped the two you mentioned, or just move the two I currently have swapped back to where they were and swapped the two you mentioned?

I did tear it all down for now it once I get it in the machine I want to get it all correct.

I was most confused in the beginning because in the original version the plus’s and minus’s were all mixed up between the two lines, but not so when I looked at Axis1. I tried to match Axis1 but the two I swapped were the only ones that seemed to make a difference.

Thanks Gary

Those sections of the PLC program do take a little consideration.

First, remember that it is initially based on the hardware jog panel and keyboard jogging, where keys have fixed addresses: the jog key in the center of the jog panel that points up (Y+ on a mill, X+ on a lathe with rear-mounted tools, X- on a lathe with front-mounted tools) is always INP1089 (or JPI33). The up arrow key on the keyboard is always SV_PC_KEYBOARD_KEY_87.

Second, note that there are several lathe configurations to be supported, preferably without having to have a different PLC program for every one:
1) Horizontal lathe with rear-mount tools: Z- left, Z+ right, X+ up, X- down (the default)
2) Horizontal lathe with front-mount tools: Z- left, Z+ right, X- up, X+ down (selected by adding 2 to parameter 1)
3) Vertical lathe with the carriage on the right: X- left, X+ right, Z+ up, Z- down (selected by adding 4 to parameter 1)
4) Vertical lathe with the carriage on the left: X+ left, X- right, Z+ up, Z- down (selected by adding 4+2=6 to parameter 1)

So the purpose of the four separate jog key stages is to map the presumably-fixed jog key addresses to the desired functions for the machine, according to the value of parameter 1.

If you compare JogKeysNormalStage with JogKeysInvert2Stage you will see that axis #1 (Z) jogging is unchanged; and that, for axis #2 (X) jogging, the references to jog panel keys (Ax2PlusJogKey_I and Ax2MinusJogKey_I and keyboard equivalents (KbJogAx2Plus_M and KbJogAx2Minus_M) have been swapped. The USB MPG jog keys (UsbMpgAxis2JogPlus_M and UsbMpgAxis2JogMinus_M) do not need to be swapped, because those keys always say "Jog -" and "Jog +" respectively, and are not laid out in a way that is specific to machine geometry.

Thanks Again Marc, understanding what those words represent better definitely helps me. I will get it changed as soon as I get it set up again.

Thanks Gary

To save a little space and make it look a little cleaner I am planning to overlap the end of the output relay boards when I mount them. There aren’t any traces close, does anyone have any thoughts or see any issues with that?

Thanks Gary

i've seen others stair step stack them to save space as well

Hello, I have a Centroid DP-1 probe and searches both here and Google turn up nothing at all. It’s sort of like it doesn’t exist. I was wondering if I change the touch surface if I will be able to use it with the Hickory to set lathe tools?

Thanks Gary

It is difficult to find information on that probe in general it seems. I found the manual for it but that is about all.

There may be some issues with lower spring stiffness causing inaccuracies when using a touch probe meant for tip down vertical use in a horizontal arrangement. We only recommend TT-2 or TT-4 for horizontal use. I am not entirely sure if that applies to the DP-1 but I can at least warn you.

Making some progress and getting ready to start landing wires on the inputs and output relays.

Thanks Gary
