When the cycle start button is pressed (2010 screen set) it turns green, is that a detectable change like an OEMLED etc?

Trying to find a way of knowing if code is supposed to be running or not without looking at spindle led's etc.

Hi Hood, good point.

Looking at it from the compiler fault view, maybe better in the macro pump after all, as a self contained monitor but if we suspect the m3 will not be called so no led's to monitor, what would it look at?

Just trying to find a way to avoid editing the PP if there is one. I have several code sources - sheet cam, fusion, vectric etc.

Whatever you do, try to run without backlash comp - it can cause more issues than it fixes sometimes, jerks and steps would be two of them.

I was chasing an off-sized result for some time when it turned out to be the tool slightly worn.

Maybe as simple as this?

m3.m1s

DoSpinCW()

If GetDRO(1010) = 0 then ‘DRO1010 is spindle power meter
  msgbox “Spindle Failed To Start”
  Call DoOEMButton(1021) ’no spindle so go into reset
End if

Is it ok to add code to the m3/m4 macros?

Seems some people get that problem and others, like me, never do but now I have said that ::)

Anyway maybe adding this to your macropump would help, it should stop the machine if the spindle is 10% out from commanded speed.

Finally got round to adding this code in but then realised the high-speed spindle has no encoder so no feedback of real speed or lack of. :(

Maybe i need to look at a simpler fix like spindle power DRO = 0 after maybe 1s delay therefore spindle can't be running??

Not sure how to code a short delay, I guess i need to add some logic like "If M3/spindle is ON and PowerDRO=0 then fault" but needs a delay maybe to allow spindle to ramp up?

Would this be better added to the M3/M4 macros so "spindle start" -> "check spindle running" -> "ok or fail"

I will have a play when i summon the whatnots to go out in a cold shop and stand at a keyboard ;)

The fact that the led goes out / comms is lost when you turn on the controller seems to tell me there is a fault loop somewhere.

If you disconnect the UC100 from the board, does the LED stay on?
Disconnect all the inputs/outputs from the board then power up, does the led stay on?

if you can get the pc/m3 communicating ok to the UC/BOB ok, then try connecting just the E-Stop circuit, then test, then gradually build up until it fails.

Sounds like you have a USB issue, maybe even an earth-loop, was this machine running or is it new???

because something is telling mach it is not possible to come out of reset.

check  stop buttons, power to breakout board, connections, look at settings screen to see if any led's are on etc.

No worries, its always the simple things that get us ;)

sounds like maybe the units are set for inches and the code is expecting metric or the steps per unit are totally wrong.

check the units setup first then verify the calibration / steps per unit setup.
