hIo, rc = mc.mcIoGetHandle(inst, "Sim0/Input0")
ioinf, rc = mc.mcIoGetInfoStruct( hIo)
rc = mc.mcIoSetDesc(hIo, "Input0 test desc")

-- this code not saving changes to profile

Mach4 General Discussion / Encoder -> Updetae Planner

« on: July 28, 2023, 12:36:43 PM »

Configure/Control/Aux Positions/  Updates Planner

What is it mean "Updates Planner" ?

I did not notice that the inclusion of this checkbox would affect anything.
Can this be used for position correction by optical linear encoders

Mach4 General Discussion / noticed two problems with MACH4

« on: July 15, 2023, 07:55:27 AM »

I have two computers:

Work computer with CNC machine:
Windows 10 x64, Integrated video card, Mach4 v5157, ESS v298

home laptop:
Windows 7 x64, integrated and optional graphics card, Mach4 v5157.

Settings and scripts on Mach4 are the same for both computers.

1) First problem:

In PLCScript,
this code

Code: [Select]

local ActiveWindowText , rc = scr.GetActiveWindowText()
mc.mcCntlLog(0, tostring(ActiveWindowText), "", -1 )
prints the name of the active window to the Log, and in Windows 7 this code works without problems.
But in Windows 10 it works with glitches. It looks like the scr.GetActiveWindowText function is not limiting the string length correctly, and writes after the correct text any rubbish. It would be nice if you fix this, or add a new function scr.GetActiveWindowTextLength()

2) Second problem:
On Mach4 on Windows 7, if you check the CheckBox "Use a frame to draw the tool path? (Restart required)"
then the ToolPath graphics window stops responding to the mouse wheel, that does not change the magnification.
On Windows 10, I don't remember if there is such a problem. If so, I'll write about it later.

Mach4 General Discussion / Quick way to update lua scripts in Mach4.

« on: October 04, 2022, 03:12:14 PM »

I found a way how to quickly change the lua script of Mach4.

At first I wanted to write a complete description of how to do this, but then I got too lazy and decided to just post the source code. I think you will understand.

If anyone decides to review this method on YouTube, I will only welcome.

Mach4 General Discussion / Re: Serial-rtu Modbus baudrate up to 1000000kbps!

« on: October 01, 2022, 04:11:35 AM »

As far as I understand, modbus has not yet been brought to the ideal?
For example, it looks like the function
"Write multiple registers 32bit (0x10)" does not work in bit packing mode. And "Write multiple registers 16bit (0x10)" works.

Mach4 General Discussion / Re: Serial-rtu Modbus baudrate up to 1000000kbps!

« on: October 01, 2022, 04:02:48 AM »

The serial speeds are actually coming from the MODBUS library we use.  I'll ask them to see if they will make it customizable.

There is a possibility to use non-standard baudrate.
I already use these settings now and it works.
[Machine.ini]
Baud=1000000
