Adding a 20% feeds button to VCP

[suntravel]

. I am working on Keith right now. I think he is close to caving in.

What can I do to help? I am usually pretty good at convincing a businessman to spend programming dollars to implement a free service that may reduce sales of one of the more popular accessories.

Choose the easy way and convince his wife that he needs a WMPG to get faster out of the shop to spend more time with her

You got that ass backwards Uwe. She would pay extra if I spent less time with her!

Slow Joe with some funny redlight is done.

Copy the files from the ZIP into your \cncm\resources\VCP\Buttons\aux13 folder

;--Feedrate Override Section
;------------------------------------------------------------------------------
; Feedrate override works as follows:
;
; 1. The PLC reads the 8 bit value of the FeedrateKnob_W directly (0-255)
; 2. The PLC scales this value to a 0-200 value (0-200%) by dividing by
;    the knob value by 127.5 and then multiplying the result by 100
; 3. If keyboard jogging is enabled, the PLC
;    determines whether the operator is using the keyboard override or
;    the FeedrateKnob_W to override the feedrate by watching which was changed
;    most recently.  The most recently changed value is saved as
;    "FinalFeedOverride_W"
; 4. Parameter 39 in (From the "params" screen in CNC12 software) stores
;    a value which the PLC program must use to limit the amount
;    of override applied to the programmed feedrate. This value is specified
;    as a percentage.
; 5. The PLC limits the override percentage by reading parameter 39 and, if
;    the feedrate override percentage as read from the knob is greater than
;    parameter 39, it sets the FinalFeedOverride_W value to the value of
;    parameter 39.
; 6. Once the override percentage has been determined and limited (if needed)
;    The PLC send this value up to the CNC12 software by setting
;    SV_PLC_FEEDRATE_KNOB = FinalFeedOverride_W
; 7. CNC12 reads SV_PLC_FEEDRATE_KNOB, factors in its own override based
;    on parameter 78 (see operators manual for more info on parm 78) and then
;    returns an override value to the PLC in the system variable
;    SV_PC_FEEDRATE_PERCENTAGE
; 8. The PLC reads SV_PC_FEEDRATE_PERCENTAGE and (typically) echoes the system
;    variable to SV_PLC_FEEDRATE_OVERRIDE which the MPU11 uses as the final
;    determination of the feedrate override percentage.
;------------------------------------------------------------------------------
; 1. The PLC reads the 8 bit value of the FeedrateKnob_W directly (0-255)
; NOTE: BTW = Bit To Word
; BTW reads the specified number of bits (if none is specified it defaults to 8)
; starting from a bit location and writes them to a word with the starting bit
; location being written to the LSB of the word used.  Below, BTW reads the bit
; values from JpFeedOrKnobBit0 to JpFeedOrKnobBit7 and writes them into to the
; word "FeedrateKnob_W" which sets FeedrateKnob_W to a value of 0-255
;------------------------------------------------------------------------------

I am watching and trying to find videos on how to implement what you given me. I really really don't want to trash my system!

Just make a copy of your cncm folder before and maybe a fresh report.
The you should be able to restore anything if needed

[suntravel]

If your NP++ is setup like in the TB294, ad the lines and hit F6 to compile.

Restart the CNC and go on.
