G-Code, CAD, and CAM discussions / G38.4 or move until probe is NOT active...

« on: June 17, 2022, 08:37:05 AM »

Hello,

I need to trigger on the probe becoming "inactive" for a move. Normally I would just use G38.4 like the following;

Code: [Select]

G38.4 Z5.0 F20
Mach4 doesn't seem to support this though. At least none of the docs say anything about it.

How do you trigger on the probe going inactive in Mach4?

Mach4 General Discussion / Re: Fusion 360 In-Process Inspection

Yes.  I've got OD Grinders that I made the code for that utilize all of those; I'm using Mach4 industrial on those machines.

OK, so it's really upgrade (which my OEM is stepping all over me anyways, time to break that cycle of frustration) and start implementing these sub programs until I can find my lazy space!

I had a boss many years ago who told me, "I only hire lazy programmers." I asked why and he replied, "because if I keep asking them to do the same thing they eventually give me a script and tell my to f-ing run it myself."

Same thing applies here...

Mach4 industrial supports G65 sub programs.

I can make all the sub stuff myself all day but the IF, WHILE, GOTO, is that also supported in Mach4 Industrial?

In-process inspection is just the killer app. I would so love to get this on my smaller machines.

Ahhhh! G65 is a sub-program. That might be what you are talking about. And that would be easy enough to write if Mach4 supports it.

Code: [Select]

N70 G65 P9812 Z-4.175 X50. R6.35 Q10. H1. M1. S1.
So that is parameters to a sub-program already present on specific machine you are using. In this case it is a outer/inner edge measurement in Fanuc system.

Here is some stuff with custom Func commands I suspect! Looks like the file operations is custom code;

I couldn't find the stuff I did back a while ago when Autodesk gave me credits for the plugins but the standard work offsets probe is the same kind of stuff, minus the 2000 lines of ifs, gotos and whiles.

So take a peek at this file and that is exactly like the full inspections.

If Mach4 Industrial does the conditionals then I will buy more credits and get a nice inspection going and post the gcode. See how hard it would be to write the post processor for Mach4.

Chad,

Thanks for the response. The probing routines are actually written out as g-code from Fusion, I don't see any macros in the output. It doesn't look like (as I have read the code so far) there is anything out of the ordinary other than a whole lot of gcode conditionals and expressions. I can see the code when I used the Haas or Func PP.

There are GOTO and WHILE and IF and all of that makes Mach4 Hobby go barf. Expressions are also though out that. So the gcode seems to have Autodesk's probing routines and the data collected is either written out to a file and/or terminates the job.

All of the actual probe gcode is boiler plate stuff and supported by Mach4. If I just cut those parts out everything compiles in Mach4. Its that WHILE and GOTO and IF [#100 EQ 0] THEN #100 = 1 (Avoid dividing by zero!)

Is that sort of stuff supported in Mach4 Industrial?


Thanks,

Mach4 General Discussion / Fusion 360 In-Process Inspection

Can Mach4 (maybe Mach4-Industrial?) perform Fusion 360's in-process inspection? I have Mach4 Hobby and maybe my OEM post processor is just incomplete?

I see all of the commands are supported with the exception for conditionals and that appears to be in Industrial. If I upgrade to Industrial is there a post processor for Fusion that supports the inspections?

This would be a huge advantage for my shop. Especially with all of the aircraft parts we produce. The ability to programatically QA would be a huge money saver.

Thanks!

Mach4 General Discussion / Is there a way to disallow M03 for specific tool numbers, like the probe?

« on: June 11, 2022, 10:16:10 PM »

My little probe has a wire, I am just not cool enough I guess.

I can make the tool change pause and ask the operator to connect the wires or disconnect when unloading. That part was easy. What I am afraid of is there will be a script that will try to machine with the tool number that is the probe.

In my case, the master tool is tool 1 thus the probe is tool one, right? I never want to start machining with my probe by accident so is there a way to check before M03 is executed to see if tool 1 is loaded and abort?

Right now if I execute a script that tries to machine with tool 1 it will ask me to hook the wires up and then it will check if the connection is closed and if so, proceed merrily along to tear up my wire and probe by spinning it up to 24k RPM. I imagine it would make a serious mess.

Thanks!
