Hello Kreider,



I don't see what defines "SV_PLC_Function_xx."



You can find what each SV_PLC_FUNCTION_XX does from the CNC12 PLC Manual starting on page 121. Typically these functions are very specific functions to command the motion control board and/or CNC12 to "Do Something". What each ...

My question is, can I modify the file acorn_universal_template.src and still use the wizard for changes going forward, and the wizard will compile my special PLC program along with any changes made in the wizard?


Hello!

To answer your question directly, Yes!, but it is nuanced. I would ...

I’m working a 12-12 shift today so I won’t be able to do that until tomorrow but I’m assuming this is just the laser gcode and does not do anything about the y delay in 5.3?


Correct i do not think this will do anything to the delay, still looking further into that. Provided G-Code should remove ...

Please Try V5.30, It should contain the fix for this.

I have an electromechanical brake on the spindle motor, and an electrical resistive one via the VFD, but the VFD one doesn't really do anything as the mechanical one engages and stops the spindle so quick. I'd like to just use the VFD one for the first 2-3 seconds after an M3 command, then have ...

When I select the Advanced I/O Configuration button to create this custom preset, it does not show that there is an expansion board and generates an error when I try to create or export the presets.


Hello, can you be more specific on the error that the wizard gives you? Maybe a snip or screen ...

Okay, I took some time to take a deeper dive into this, and followed the trail of G65's. There's an error on lines 183 and 188 of "touch_plate_cycles_select.cnc". It looks like it was just a copy/paste, forgot to change it kinda thing. On both lines, the axis label assignment for Y (axis 2) was y ...

Thank you. I will run that first thing tomorrow.

Now we just need to Parameter 42x that adjusts the Y delay

After looking into it more, The Change in the Y ZigZag file may correct the issues with the delay for Y-Axis.

Hello,

Could you try running this version of the file that is attached.

Hello, I have the same question for the Allin1DC control. I tried the Acorn PLC modification but it is not working.


For Allin1DC, the logic is a little different from Acorn. If you are using the Spindle Brake PLC for ALLIN1DC (Centroid_ALLIN1DC_Mill_SpinBrake-r5.src) then you should have the ...
