Lose work coordinate zero at the end of NC program

I have had this before but it just went away???

I am using fusion 360 to Candle to arduino board to gemitsu 4030.

I complete an NC program.

The bit stops where the NC program shows it should stop.

Candle sends a message "Job Complete".  Unless I click okay all I cannot jog the machine.

The only key that releases it is reset on Candle.

When I hit this I lose the zero (XYZ) the reset to machine coordinates.

No matter what I have to jog the machine to reset the Z coordinate after the tool change.

Right now I have to reset XYZ  which is of course introducing errors.

What is happening????

It doesn't quite sound to me that this is a Fusion issue, but possibly a machine controller issue. The "Job Complete" likely only pops up when the controller reads the M30 line, which is the end of the program. Have there been any software updates for your controller, and are there user forums for your machine where you could ask about this issue?

Yes i have asked them about this issue.

 

if i could tell fusion to stop and return work xy zero.  I could hit reset then rezero xy (two clicks). Then jog as required for bit change.

Oh, that's an easy enough thing. 

To test, put a G54 X0 Y0 right before the M30 (in the g-code). Once you confirm that does the trick, we could modify your post processor to automatically include that line

Tried easel to see what happens.  

it does not send a job complete message at end of job

it returns to work xy zero z3.8

i click pause abort.  And jog is operable work zero maintained

 

thisbwould also work fine

Okay looking good.  

So I installed the g54 x0 y0....I also deleted M5 and M30....in the hopes that it would work just like easel.  That is not send a job complete message then I could hit pause abort and ready to go....

But it still sent a job complete message and locked out jogging. so I hit reset then unlock the set xy...

Jogging enabled, xy zero retained.

However the bit trace did not show the move from end of cut to G54 x0y0 (suppose a nice to have).

I also changed the Z15 just prior to g54x0y0 to z10....just cause this is where i normally put the z when restarting...

 

So what are the next steps to get fusion to put this in the gcode automatically....

 

Also candle appears to be working normally as always.

Which post processor are you using, so we can provide you with accurate steps to modify for the behavior desired?

Is this the end result you're looking for?

G0 Z15
M9
G28 G91 Z0
G90
G54 X0 Y0
M5
M30

Yes that works

 

i would also like to possibly remove m5 and m30

Message 13 of 21

To what end? The M5 turns off the spindle and the M30 finishes the cycle and sends it back to the start of the program. If you're running multiple pieces, how do you propose starting the job over?

First I only have a router plugged into  the wall so i manually deal with that.

Second the M30 is not resetting the program in candle (neither does easel)...

So I have to hit the reset program button in candle anyway...so suppose it doesnt matter really

I guess if I was using a wcs origin to run another job on the same stock with the same tool...it would be handy...depending on what candle would do???

right now I just copy the body or component in design and in manufacture just do all the tool paths...

I only have a personal license...I make skiis so I just do everything for one pair of skiis at a time.

so yeah i guess I just need the g54 x0 y0...

Well, that makes sense. Give this post a shot, this should be the result you get:

G0 Z15
M9
G28 G91 Z0
G90
G54 X0 Y0

K I think i go to post library and import file from my downloaded cps file...

Then I go to machine library and change post to this file...

Then create a nc program and read changes to gcode?

 

Here goes

Et voila

Cant thank you enough for helping me through this....what program language is the post processor written in???

Don't put the file into the generic post library, it will be overwritten at the next update. Rather, turn on Cloud Libraries and upload it to your Assets folder. Otherwise, your steps are correct

It's just JavaScript. I'm not the handiest when it comes to making edits, but I can muddle along okay-ish
