M09 Turn Off Coolant Sooner

[Gcode66]

What is the best way to alter the Generic Fanuc post to turn off the coolant on the same line as the retract to Clearance Plane at the end of a tool cycle?

I dont think you can place it directly there as it would involve the pzout variable and it might output a coolant code on every line there is a Z, however I placed it next to the M05 which is the line right below what you wanted and this is on a separate block.

pbld, n$, sccomp, *sm05, scoolant, psub_end_mny, e$ <------- added scoolant here

The code looks like

N124 Z.2
N126 G0 Z.25
N128 M5 M9 <-----M9 before the move home !
N130 G91 G28 Z0.
N132 A0.
N134 M01

There are a good number of CNC systems that don't allow more than one M-code on the same line.

Double check.

 

For machines with under-powered coolant pumps I've created an M09 custom M-Code alias

that has a 1 or 2 sec dwell to ensure the coolant is off on the return home.

I do the same in reverse for the M08 to make sure the tool has a sufficient coolant wash

as it begins the operation.

The MPMaster Post Processor outputs the code where we need it. I'll look into how they're doing it tomorrow and see if the code can be added to the Fanuc post. Having (2) M codes on 1 line was a concern of mine. I'll double check our machine manuals and see if it's supported.

I hardcoded an M09 into the pretract postblock. Doesn't hurt a thing.

Find the line Greyman shows (below) and add this line just above it.

pbld, n$, "M09", e$

 

pbld, n$, sccomp, *sm05, scoolant, psub_end_mny, e$ <------- added scoolant here

 

 

You may also want to add that line to the null toolchange retract postblock as well. (pretract0)

Problem solved and forgotten about in less that a minute!

+1 K2csq7™, Our machines have no problem with two M codes on the same line, now our HAAS lathes a different animal. I had no need to hardcode my M9 as our machines support it, but what K2csq7™ did above works for those that need the code in that format.

Thanks! That'll work.

BOOM..... HEADSHOT!!!

ROR!!!!

MPMaster is a WAY better post than MPFan.

 

Just sayin'

[Gcode66]

Agreed. I've subsequently modified the MPMaster post to suit our needs and ditched the MPFan.
