Still struggling to get hand wheels operational.

Post by Chas »

Hi, i have modified the plc program as per Tom Blough's post of Sat Sept 5th but still no life in the hand wheels. I have rechecked the wiring and everything is as it should be. hand wheels are connected to axis 3 & 4 inputs. I'm guessing i'm missing a step somewhere in getting them to act for Axis 1 (Z) and axis 2 (X). Any suggestions greatly appreciated.
Report attached.
Thanks
Chas

If you made necessary changes in your PLC program source, did you then compile the new PLC program into mpu.plc?

Hi, er no I didn’t. Is it simply a matter of removing the standard oak src file and pasting in the revised one.
Many thanks

All the Centroid manuals are located here: https://www.centroidcnc.com/centroid_di ... nuals.html

This one will show the PLC compile and installation procedure: https://www.centroidcnc.com/centroid_di ... manual.pdf
Cheers,

Soory guys but still struggling with this. Have altered the Centroid Lathe-Standard-Oak-r4.src file and the MPU.plc file to match but still no joy. I believe the software brings up an alert when a change is made to the program but i don't see that so i assume i haven't made the changes correctly. i have noted that the mpg button on the vcp cannot be changed but that may just be that it only functions when a centroid handheld pendant is attached, i don't know. The handwheels are operational as if i switch axis 3 and 4 on i get readouts from both when i turn the handles. Very frustrating as everything else works great now. Report and copy of modified src file attached.

You don't edit mpu.plc in a text editor.

You edit your source file in a text editor, then compile it.

Suppose you have decided to name your new, revised PLC program source "Centroid-Lathe-Standard-handwheels_v3.src". Then, with a command prompt window open, and in the c:\cnct directory (so the prompt in front of your cursor reads "C:\cnct>") you would enter the command:

Code: Select all

mpucomp  Centroid-Lathe-Standard-handwheels_v3.src  mpu.plc

After you type the "mpucomp" command, then look to see whether the resulting messages include something like:

Code: Select all

Input file : Centroid-Lathe-Standard-handwheels_v3.src
Output file: mpu.plc
Compilation successful
... plus some statistics about program complexity and size.

If you don't see "Compilation successful", or the output file is not "mpu.plc", then your changes are not going to take effect.

cd c:\cnct
mpucomp Centroid-Lathe-Standard-handwheels_v3.src mpu.plc

Two different commands. First changes to the cnct directory. Second compiles the plc program.
