Hey guys,

I have a question in regards to adding in G & M codes after posting your BC code. For instance, I have to enter an M code in for the Haas thru spindle coolant On/Off. How can re-sequence the line numbers so they are in order if I have to manually add code? Thankfully this step was toward the end, so I manually re-keyed the line line numbers in. I tried with Predator and adding a sequence number but it just added a sequence number that was already used and also out of sequence (see below).

Example: M88 to turn on TSC

(TOOL #10 Badger UNC 5/8-11 Hand Tap)
N499 T10 M06
N500 T13
M88 <-------- NEED TO ADD A SEQUENCE NUMBER BUT HOW TO YOU RE-SEQUENCE AFTER YOU ADD? This would become N501 the next line needs to be N502 and so on.
N501 G90 G54 X1.5 Y2.1275 S98 M03


Predator did this:

(TOOL #10 Badger UNC 5/8-11 Hand Tap)
N499 T10 M06
N500 T13
N510 M88 <------ OUT OF SEQUENCE AND N510 IS ALREADY USED
N501 G90 G54 X1.5 Y2.1275 S98 M03



Thanks for the help.

If you delete a block of code does your machine run what's left without errors?
If so could you modify your post to change the line number increment from 1 to 5 thus leaving yourself gaps in the numbering for line insertion?

[The Engine Guy]

Couple of ways to fix this, either go to your Milling Job settings and set the Posting numbers to 10 instead of 1, that way all your lines of code will be 10 digits apart ie N500, N510, N520 etc, that gives you spaces in between to insert any modifications required, I generate all my code this way, make for a much simpler life

Probably the best way is to modify your PP so that it outputs the M88 for you correctly by using an "Advanced Posting" PP, if you can`t do that then if you are using a HAAS VF PP go look at blocks :-

706 Coolant Mist Code? "M07"
707 Coolant Air Code? "M07"
708 Coolant Oil Code? "M07"

You should be able to change one of the "M07" commands that you never use to the "M88" for example the 706 Mist block, then you can set all your Through Tool Coolant tools with the Mist option, that should then automatically produce the M88 whenever you choose a Through Tool Coolant tool

Or you can just select the Mist option on your tool information area in any given feature

Hope that is of some help to you

That is a good plan
but the haas don't need sequence numbers
that just for the guy running the machine to have a place to jump
into a program. why would they jump in at a M88 line?
they will jump in at a safe start point

If you only need one coolant on at a time, Rob's solution is by far the easiest way to go about it. You can use the drop down menu in the feature for coolant options and it should post the correct code (never tried it myself).

The other alternative is scripting the output, also as Rob mentioned

I assume you don't want it to come on all the time so you're going to need add an Advanced Posting tab to all of the features you want to use it on, or create one "shared" posting page as explained in the Documentation folder of the BobCAD-CAM Data Vxx folder:

.CustomDrillCycles
All Mill Hole Drilling Operations
.CustomMilling
All non-hole Milling operations (2 Axis-through-Multiaxis)

Add a checkbox (TSC On) in the .CustomMilling/.CustomDrillCycles file so that you can use a program_block_x call in the post to read it right after your tool change or in Block 4 (null tool change). Probably in multiple places, really.

Then I would add the TSC off (M89) manually (hard code it) at each tool change and at the end of file. I don't think you need to be fancy and set a conditional off switch, if you are using TSC for a certain tool you'll probably be using it throughout the use of the tool.

The program_block_x is probably going to be pretty simple. Something like an if/then statement. If checked then output M89 else donothing. I always do the "donothing" or something similar just to test the script. Once you are sure it's going to work you can always delete it out later. Or not, it's just a simple one line comment.

Hi guys,

Didn't even realize I had these great responses. For some reason, I don't always get the email alerts when someone posts. In this instance, I only had an alert from 'magicniner' above. I guess I haven't tried it without sequence number on my added code as mentioned by WILDMAN2. I could test and see if the Haas errors out.

Great ideas. Rob, both ideas are great. Either would satisfy my needs if not both. As a test, I changed the Oil "708" to be an M88 and sure enough it posted just as I needed it. The only thing I would need to do is manually add the M89 to shut the spindle coolant off like SBC Cycle said.
I guess I could certainly do a combination of the 2 ideas by change the sequence number increments and change the 708. The only caveat is if I wanted to do TSC & flood the same time. As a test I did this:

708. Coolant Oil code? "M88 M08"

It actually did post both coolants as you can see: N05 G43 H1 D1 Z1. M88 M08

I only need to manually add the M89 prior to the next tool change. The M09 does post on its own to shut off normal coolant.

SBC, you obviously know your post modifications But you are correct, we don't want TSC all the time as not all our tooling supports it. I may need to personally get with you to help me out. It sound like that is another great long term solution.

Thank you, much appreciated. The solution I tested is pretty much effortless. In all honest for the little code that I would ever add in the near future, changing the sequence number to increment by 10 instead of 1 and do a little data entry, would be fine. Didn't even know this ability was possible.

[Rotax91]

By the way, I haven't physically tested this yet to see if you can have 2 M codes on the same line: N05 G43 H1 D1 Z1. M88 M08

The post notification emails only trigger for the first reply to your subscribed posts since your last visit to the forum. So if you get a email notice, and visit another section of the forum, it resets and will send you a notice with the next post to that thread.


The way bobcad has gone about making their post processors is by far their best hidden feature in my opinion. They are the easiest post processors to edit that I have come across. Its saved me quite a bit of time in hand edits, being that I can easily tweak the posts for each machine.

And if you have support, and need your post to do something obscure, their team can do just about anything you can think of. My CNC at home was setup to output the spindle speed 0-100%, rather then the RPM output. I had bobcad make me a post that did the calculation for my spindle speed. I later found out that I could change the min/max RPM settings in my CNC Controller, so I no longer need the custom post.

Hmmm, that will be interesting, I don`t have any experience of HAAS controls so maybe you can have two M codes on the same line but it isn`t normally allowed on any control that I have come across so far

OK, I have done a little bit of work on a simple Advanced PP for you, I`m not very good at this, really needs SBC on it if he has the time

It does work here on my V28, but as I don`t know what version you are running (It`s probably in a post somewhere that I haven`t read properly ) I haven`t uploaded the BobCAD file

Anyway I`ve attached thePP and the two Custom files in a Zip file, all you should need to do is to open the Zip and simply copy and paste the three files into your MillPst Folder in whatever Version you have.

You can then open a new BobCAD drawing and set the PP in your tree to the new Custom.MillPst and road test it

All the files you can open to view and edit in Notepad but always remember to just "Save" them, don`t do any "Save As" just for safety

You can alter any PP (A copy of your HAAS one if you like) to output as the attached PP by just typing in any number/text you want to appear in your code line.



I have also set up an M89 to cancel the M88 and it should work, if not then you might need to hand edit a little However if it is anything like my machines the unless the M88 command is already "Active" in the control it should ignore the M89 without any errors

See the code below for a couple of pockets one with a finish and one without and a drill cycle, when you use the PP it will create an "Adv Posting" tab in your feature where you can select the correct type of coolant for every different tool

Hi Rob,

I really appreciate you taking all that time to help me out. This is great stuff. I see you got to post both M88 & M89. I want to try this out ASAP. I know where the Custom.MILLPST files goes but what folder do you drop the other 2 files into?

A little while back, I made a modification to my post with some previous help. That change was to do a next tool precall. Made the cycle times quicker having the next tool on deck. I should be able to incorporation that code into your post.

By the way, I do have V28.

THANK YOU!!!

[The Engine Guy]

All three files need to go into the same folder, ie your V28 MillPst folder, they have to be all in the same folder for it to work

So that would be C:\BobCAD-CAM Data\BobCAD-CAM V28\Posts\Mill for most PCs

Hope it works for you, it is one I had from a few years ago that I have modified to suit your requirements, not sure now but I think it was originally done by either SBC or Al, I can`t take the credit for the original, only the mods

Just got time to look at it Rob, it works beautifully!

Rotax91,
If you need both coolants on at the same time you could add more conditions to the drop down menu such as "TSC On, Coolant Off" or "TSC On, Coolant On" and then modify the Case statement accordingly. However, I am in doubt about whether they can be on the same line in the Haas Control. I don't have the TSC option on any of my machines so I can't test it.

If that is the case, you may need to re-add the normal coolant_on line somewhere in the Tool Change and Null Tool Change sections of the Post and control it normally in the Wizard dialog. It would probably be just fine if you added it right after the program_block:

n,program_block_1
n,coolant_on

Very easy and simple script to follow. Good stuff!

EDIT: To my knowledge it may have been our old friend "The Bird" that gave us all examples of how to use scripting. As soon as we had the ability to script our posts the first thing I asked for was an example of a simple coolant on, coolant off function. Coolant used to be hard coded into the post and there was no way to selectively turn it on or off. I run plastics as well as steel so that made it very easy to control without having to have two posts.

FWIW I rarely use much scripting in my post anymore. The posting engine is now very mature and handles just about everything I need. But when you need it, you need it! Glad everyone is making use of this awesome feature.
