Mach4 General Discussion / Re: how can i use my own lua libraries in mach 4 ?

« on: April 24, 2018, 10:39:13 AM »

any lua/dll module/library that is located in the 'modules' directory that conforms to lua 5.2 can be loaded at run load time, see the screen load script:

--Master module
package.loaded.MasterModule = nil
mm = require "mcMasterModule"
   
--Probing module
package.loaded.Probing = nil
prb = require "mcProbing"
--mc.mcCntlSetLastError(inst, "Probe Version " .. prb.Version());

If the module extension is different than .lua then change your load path to search for that as well.

package.path = path .. "\\Profiles\\" .. profile .. "\\Modules\\?.lua;" .. path .. "\\Modules\\?.lua;"

LuaJIT is a compiler.  Mach4 runs it's own compiler to compile all lua, mcs files at each load and I don't believe you can just include the compiled module in the modules directory, but then again I haven't tried.  Good question though.

I'm not sure if the sci modules are 5.2 compatible.

Mach4 General Discussion / Re: mcCntrlGcodeExecuteWait fail

« on: April 23, 2018, 12:31:51 PM »

When I first started coding with Mach4 I put everything in the button mouse up script.  I generated a line of gCode and then ran mcCntlGcodeExecuteWait for each line.  I was told that was wrong that I needed to generate a string consisting of lines of gcode separated by newline characters.  Which I did.  I then started getting a huge amount of code included in the screen button scripts so I created a module to reduce the amount within the screens.  I then thought I should just write macros that called the module's functions and create the string.  That's when I ran into this 'new' limitation that nobody seems to know the answer to (lua defaults to 4096 characters for a string which this example doesn't exceed).  No one knows if this is due to a look ahead problem or a line limit with mcCntlGcodeExecuteWait.

So I thought that I would just run the macro to generate and save it as gcode file, load and run it.  No can do.  Can't load a gcode file while running a macro (error: not now).

So I am back to button scripts that generate the gcode file, save, load and start it.

Mach4 General Discussion / mcCntrlGcodeExecuteWait fail

« on: April 09, 2018, 01:19:25 PM »

I have a macro that generates a string of gcode listed below.  If I pass that string to mc.mcCntlGcodeExecuteWait(inst,s) it executes to the x1.320 then skips the rest of the gcode in the string and executes the remaining macro code after the mc.mcCntlGcodeExecuteWait(inst,s). Is there a limitation as to how many characters/commands that can be included and executed in a string with executeWait?  This code executes as a gcode file so I know it is not the code.

Code: [Select]

Mach4 General Discussion / Re: Lathe Problems with Mach Motion Wizards, Is this Gcode Good?

« on: April 09, 2018, 11:08:05 AM »

While manual editing of the output works you can eliminate this by selecting the in-feed option every time.  While the GUI shows something as being selected, like 'Flank In-Feed, Constant Depth', it will always output a k=0 value unless you re-select an option each time.

Just one of many flaws in the turn cycles wizard.

I think this may be time to open a ticket with NFS to determine if it Mach or motion control related.  sorry I can't help more.

I'm surprised that the threading code ran at all.  the N0085 G76 contains a k value of zero which is not valid.  Are you running hobby or industrial?

M98 calls a subroutine not a tap/gcode file.  The subroutine is defined after.the main gcode(m30) and starts with the letter o followed by the same numbers that follow the p parameter in the m98 call.

Your m98 is calling p02

You don't have a
o02
You have a

Mach4 General Discussion / Re: How to setup Auto Zero button in latest version of Mach4

When you load mach it re-compiles all scripts and macros so if you have checkProbe() defined in any other file that contains an error mach will not compile correctly.

Move any files with the code you are trying to debug to a directory outside of your mach directory.  Start mach.  If you still get an error like the 'failure while running chunk something else is wrong.  If not then:

From Operator->edit/debug scripts select any m???.mcs file.  Then when in the editor select file->new.  With notepad cut and paste the code into this new file and hit F7.  Now you should get where the offending line of code is.
