allin1dc MP11 probe help with pictures

[cncsnw]

The simplest way is probably to add a line to InitialStage in your PLC program, to invert INP769.

See https://centroidcncforum.com/viewtopic. ... 19&p=47777 and scroll down.

Is there a way to connect a 3 wire hall effect / magnet to a Allin1dc spindle encoder input just to display RPM in CNC 12.

Not really. A circuit would be needed to convert to encoder - like signals. The software readout may not work with 1 count per revolution even if you did that. There are links to very low cost encoders on the forum. One of those would be a better choice.

I have inverted the probe input 769 to NC and tried a simple probe that is 2 wires, now when I run a probing routine the machine does touch and back off numerous times then fails the probing routine. I also tried the code below but couldn't get it to compile. I tried MEM30 and other MEM positions that I thought were unused but no luck.
Out of the whole retrofit this probe stuff is kicking my butt.

You have Parameter 155 set incorrectly.

Parameter 155 should be 0.

What code is that?

[craigc]

Thanks for your help. I feel dumb. Here is the code I was trying but maybe I don't need to bother now.

;...
MechanicalProbe IS INP769 ; N.O. probe: 1 = tripped, 0 = idle
;...
ProbeDetect IS INP771 ; N.O. detect: 1 = present, 0 = not present
;...
ProcessedProbeTrip_M IS MEM30
;...
ProcessProbeFastStage IS FSTG1
;...
;========================
ProcessProbeFastStage
;========================
; Report probe trip if the probe is connected, and tripped
IF ProbeDetect && MechanicalProbe THEN (ProcessedProbeTrip_M)
;...

I don't see anything glaringly wrong with the PLC code fragment.

If I recall correctly, your PLC program does have some other definition for MEM30, but that usually just generates a warning, not a compile error.

Perhaps you tried to insert your new stage and associated logic in the middle of the definitions section, instead of down in the program section?

[craigc]

Thanks for looking at the code. I will correct the input 155 first and see if it works correctly then try the probefaststage following your help.

I will try and post my findings to help others as well.
