M8 Coolant Issue

[Anonymous]

I'm having an issue with a posted program not turning on the coolant with the M8 command. I'm using Fusion 360 and a Siemens 840D Controller. the post has the M8 command but will not turn the coolant on automatically. I can turn it on manually and it will shut off for the automatic tool change but will not restart unless I turn it back on manually. The post I'm using is - Siemens SINUMERIK 840D / Siemens 840d. Any help would be greatly appreciated.

Are the tools in your tool library set to use flood coolant? Or is the program posting a M8 and the control not honoring it?

As a test put M8 into the MDI, by default the M8 is in the post if this fails, try M7.

Yes, it is loaded into the post but does not turn the coolant on. All the tools are set up for flood coolant in the setup.

Using M8 in the MDI the coolant works just fine. I tried using M7 in it's place in the program and that did not work either.

if there are set up in the tool definitions, make sure you have the latest version of the post. There is a comment on the change log on 4/1/2019 that there was an edit "Fixed potential coolant output issue. (#87)". The first section of the post to check would be,

The post I'm using is just as the screen shot you posted, the date however of the revision is 09-06-2018. Not sure how to download/upload a new post revision but I'll take a look at it.
