Build Thread Mach3 to Acorn

[ShawnM]

My plasma table homes the torch outside the water table and after it homes I have it move the torch just inside the water table and set X,Y and Z zero at this location. This is all I have for a homing file on the plasma table and it works every time:

M92/Z L1
M26/Z
M91/X L1
M26/X
M91/Y L1
M26/Y
g53 x4.5 y1 z0
M26/X
M26/Y
M26/Z

Another issue I am running into.

At m6 I want the prompt to change tool. That does happen
THEN - I want the tool to go to Auto Measure. that does not happen
AFTER auto measure I want to return to G54 X0Y0 and continue program - Not going to auto measure so this is moot.

report_80F5B521CAF7-1109215356_2025-01-09_12-52-36.zip

to do this you edit the M6 with the actions you want.
I tried a few different mfunc6 formats from this thread - they all look similar

do you have a fixed TT? or a moveable one?
FIXED

do you plan on retaining a tool library or do you always want to measure and remeasure at every tool change?
Remeasure every tool

On your homing issue, it's strange that I've never had that problem in 6 years of using a similar homing file. I tried yours on a small benchtop machine, and it happens to me as well. The only way I can get it to work consistently is to set the axes home with M26/ first, and then do the G91 followed with another set of M26 at the end. You could use this for both initial home and reset, or just use it for the reset macro (mfunc59.mac).

For your M6 question, there's no mfunc6.mac in your report to look at.

Code: Select all

;Perform Homing commands
M92/Z L1
M91/Y L1
M91/X L1
M26/X/Y/Z
G91 X.25 Y.25 Z-.25
G90
M26/X/Y/Z/A

I will try this


mfunc6.mac is not in the main folder --- system? ATC folder

So the homing worked

M92/Z L1
M26/Z ; needed to be here
M91/Y L1
M26/Y
M91/X L1
M26/X
G91 X.25 Y.25 Z-.25
G90
M26/X
M26/Y
M26/Z
M26/A

Reset home worked once, but I will test a few times tomorrow
It does make sense to rezero

- you have to create the mfunc6.mac file. by definition mfunc6.mac is a custom file.

if mfunc6.mac doesn't exist CNC12 performs the default M6 action.

and yes place mfunc6.mac in the cncm directory so CNC12 knows that you have a custom M6 set of instructions and will use it.

[cnckeith]

are you setting part zero with the TT? i.e. are you always setting the spoil board to Z0 or the top of the part?

here is some m6 code for Tool Touch Off, adjust it as needed.

if you configure CNC12 with the Wizard for Rack Mount ATC (with zero bins) the Wizard will generate this code for you in the M6. i use it to do most of the work and then edit the way i need for a particular workflow/customers request etc.. you can do the same. copy the mfunc.mac that it makes,
then just put the Wizard back to "None" in the ATC setup menu, write settings, and then go back in the ATC menu choose "Yes" to Custom (M6) in use. so it won't overwrite your custom M6.

Thank you Keith - that answers a lot.

I have a little job to do this morning and will try some stuff later today.

[Leo Voisine]

This is certainly a huge learning experience for sure.

Right now I don't have a problem ---yet --- but there is for sure a learning experience.

[cnckeith]

fyi..that TT code is made so it works with any setup, yep looks intimidating..but you could of course 'hard code' those variable values for your particular setup, that makes the macro a little less scary.

for others reading this. here a link to the Centroid macro programming guide. https://www.centroidcnc.com/centroid_di ... amming.pdf

[Leo Voisine]

I have the macro programming guide.
I have created Family of parts macro programs before, so I am not too much intimidated. The language is a little different than in Fanuc but it is similar

I am working on my Mfunc6.MAC and so far it is working great - EXCEPT - it is not adjusting for the height of the tool setter variable 71. I can see the correst number in 71. Using the Auto Set to set the tool it works, but not in my Mfunc6.MAC

I don't know how to
1) Look at the Auto Set macro to compare the differences
2) Look at #106 - or any user variables

mfunc6.mac
