We use these and would be "shocked" to find milling is faster than these drills. http://www.iscar.com/Products.aspx/CountryID/1/ProductId/10146

I agree X5 did help this, but if your not planing to upgrade to X5. Then just restart you computer. When I noticed it getting real bad I would just restart my computer. Just closing mastercam and re-opening it does not seem to help. A computer reboot is what I always did (couple of times a day )

Couldn't agree more, its not like this is a fancy feature or something its just coolant. By the way I don't consider that a rant, we have been patient long enough. Its time to fix the coolant for good.

Do you typically go to the coolant page each time you create a operation?

That's a new one for me too.

Are you selecting the tool by typing in the tool #?

My coolant works just fine as long as I go to the coolant page and just "view" it, don't change anything, just go to it. I guess I will just have to wait till the next release if it is a bug. Could not use X5 because coolant settings would not stick, now I can't use X5 MU1 because coolant won't come on unless I view the coolant page. I say this based on the information I have been able to gather to this point unless I am missing something. So much for maintenance.

Was wondering where you have them set in your post? I have tried both "before" and "with" neither seems to work. I also seen a topic where you were having trouble and you ended up having to change the v9 setting in your defaults file. I have already done that as well.

Are most people using v9 coolant? Those that are using X style coolant how do you have yours set?

Going home for the weekend, hope everyone has a good weekend. Thanks to everyone for all the help so far, hope to get this solved so I can use X5.

It is now on the ftp site under X5 files, called V77.Z2G M8 - FLOOD M7 - AIR BLAST M77 - THRU SPINDLE AIR M26 - THRU SPINDLE COOLANT

I have flood coolant, air blast, thru spindle coolant, and thru spindle air.

There are pcan, pcan1, and pcan2 but is there a certain place they need to be? I can't use v9 coolant if I have 4 coolant options can I?

After looking at my post I do have the command "scoolant" in start of file part of the post. Changing the coolant to "before" does not help. It seems to just do it when there is a new type of operation performed. As in if I use a circle mill toolpath and it is third in line to be posted, but the first time I used circle mill in the part it won't turn it on. But, if I have another circle mill toolpath just after the first one it will turn the coolant on. It does this with all the different toolpaths types. Why does X style coolant have to be so hard to use? I just started using X5 because the first release won't even hold the coolant settings and now this.

Looking further it seems it does not turn my coolant on for the first operation of any type. Ex: the first contour cycle, first drill cycle, first pocket cycle, etc. The second cycles always turn coolant on.
