Software Feature Request: spindle speed adjustment

[avp]

Hello,
sometimes I manually adjust spindle rpm while a job is running. I find that the + - rate at which it adjusts the rpm is very quick.
It would be nice to be able to adjust the rate at which these buttons work. Sometimes just a tap will be too much, a slower rate would be nice.
Any thoughts?

I agree Bill and I think the new USB board that they are working on will even have an analog input for a pot to be even more adjustable. I think the current jump now with just a click or tap of the + or - VCP button is 10% of it's current speed with is usually too much. Don't quote me on that but I think I read that somewhere in one of the manuals.

From a sample PLC program:

Code: Select all

;------------------------------------------------------------------------------
;          SPINDLE OVERRIDE CONTROL
;       Jogboard (-, +, and 100% keys),
; Keyboard "ctrl" + "<", "ctrl" + ">", "ctrl" + "/"
;------------------------------------------------------------------------------
IF SpinOverPlusKey || KbIncSpinOver_M || SkinSpinOverPlus_M
  THEN SV_PLC_SPINDLE_KNOB = SV_PLC_SPINDLE_KNOB + 1
IF SpinOverMinusKey || KbDecSpinOver_M || SkinSpinOverMinus_M
  THEN SV_PLC_SPINDLE_KNOB = SV_PLC_SPINDLE_KNOB - 1
IF SpinOver100Key || KbSpinOver100_M || OnAtPowerUp_M || SkinSpin100_M
  THEN SV_PLC_SPINDLE_KNOB = 100

So, as long as the key is held down, the override percentage increases or decreases at a rate of 1% per scan of the PLC program.

Since the PLC program scans approximately 50 times per second, the override percentage will change at a rate of 50% per second, in 1% increments.

To make it change slower than that, you would have to add logic (perhaps similar to that which adjusts the feedrate override, in "KbOverride_W", using a timer) to prevent it from changing in every scan.

You could try just putting in a fractional increment, but I think SV_PLC_SPINDLE_KNOB is an integer value, so that probably will not work.

I offset it with slowing the feed rate and one affects the other with spindle speed. I do agree having a slider, or way to go slower would be nice.

Try using the WPG Pendant's wheel. Works as fast (or as slow) as you desire.

that's what i do.. love it can't live without it! set to SPIN and turn the MPG wheel.. easy peasy

Yes, true.
Didn't think about that.
