Mach4 General Discussion / Re: Signal Number Definitions

« on: February 18, 2021, 11:54:38 AM »

I am very new to Mach4 and Lua so am undoubtedly going to ask some very naïve questions.

Can I replace this code:
Read_Signal(1142)

With this:
Read_Signal(mc.MC_SPINDLE_FWD)

I am new to Mach4 and am trying to get modBus working for my Hitachi VFD. Nothing like biting off a difficult problem to start with. PMC is what generates that number. I see that in this section of code: "return mcSignal(1142)". What is the appropriate way to access that signal?

That post did not have the answer I was looking for, but it was very informative. Thank you.

Mach4 General Discussion / Signal Number Definitions

« on: February 14, 2021, 03:55:00 PM »

Where can I find the definitions for the Mach4 signals?

I see the following in Lua code: return Read_Signal(1142)

I need to know which signal 1142 is associated with.

What is the Prep. Distance used in the touch probe setup? The description in the documentation does not tell me much.

Mach4 General Discussion / Do I need Hobby or Professional?

« on: November 30, 2020, 11:55:57 PM »

I am planning to upgrade my Mill software from Mach 3 to Mach 4. I need to determine if I need the Hobby or Professional version.  Here are the 3 needs I have that I am not sure will be supported by the Hobby version.

1) I have custom z-height setting code with buttons that I added to the screen to run the custom button scripts I wrote.  Will I be able to add buttons to the screen and implement new code to do this?

2) I have encoders on both gantry motors so I can detect a motor stall and then issue an e-stop to prevent significant racking.  I wrote this as a brain in Mach 3. I realize Mach 4 does not have a brain, but will I be able to write code to read encoders and issue an e-stop command?

3) I have a custom wizard for cutting dovetails. Will I be able to write my own wizards?

Brains Development / Reading Spindle RPM via Modbus

« on: November 28, 2017, 12:08:56 AM »

I am using a Hitachi x200 VFD and I have a brain set up that controls the direction and speed of the spindle. I would like to read the RPM of the spindle and display it in Mach 3. I did not write the brain I have and know little about Modbus. I would be glad to purchase a plugin if available. Does anyone know of a plugin or can you point me in the direction regarding how I modify the setup to read back the RPM?

Mach support solved the issue. I need to run the program as Administrator. Never had to do that before. Not a big deal for me, but for shops with multiple employees I can see how they may not want to give Admin privileges to everyone running the machine.

I think I would do a clean install of Mach3 and enable modbus in one of the default profiles to see if the issue still exist.

That was a very good idea. Unfortunately it did the same thing. I tried to make sure my machine was clean of anything previously installed so I uninstalled Mach, deleted the entire Mach3 directory, and deleted any registry entries that had Mach3 in the name. The clean install using a default profile did the same thing. I am running version 3.043.062.

I would appreciate it if someone else would try temporarily enabling Modbus on the Ports and Pins configuration screen. Then close Mach and try re-opening. Will you have to kill Mach in task Manager or re-boot to get it to start? The reason I am asking is because all of my machines have had my XML file on them and I want to make sure that something is not hanging around. If this happens on someone else's machine, I can be pretty certain it is a Mach problem and not something to do with  my configuration.

Thank you in advance,
Kent
