Mach4 General Discussion / Re: Start Mach4 in Screen Editor

Ok.  So I made a copy of the Mach4GUI and just put the property of "/e" in the line and it allowed me to open into the screen editor.

I must have really screwed something up.  It still won't open and tells me that I have something wrong with the PLC Script.

C:\Mach4Industrial\Mach4GUI.exe /p OD_Grinder/e

Here is the path that I'm using.

Still Lost.
I cannot use "/"  while renaming anything.

I'm in industrial, but I assume that should still be ok.
Also, I can't figure out how to get this to work.
Do I rename the Mach4GUI?  Or rename my profile?

I have messed up my PLC script bad enough that Mach4 won't open.  I can't remember how to open Mach4 in the editor mode.  Anyone remember how?

Tried to enable some PMC code and it really didn't like it... so now I can't open Mach4 even if restore a previous backup.

Thirdly, G28 - that moves back to the home switches, right? Is there a way to programmatically set a user-defined home position?

You can use G30 instead of G28.  Populate the System VARS#  5181-5183 (5181 = X 5182 = Y 5183 = Z).  You put in the Machine Position you want it to go to into these variables. 
It is best to have homing on your machine since this is where it will go every time. 
It won't go to the home position unless you leave the #VARS 0.00

Mach4 General Discussion / Modbus communication status

« on: July 30, 2021, 03:45:47 PM »

I'm wanting to monitor the status of my Modbus connection. 
Under the Register Diagnostics my Modbus rc shows 2 when there has been a loss of communication -1 when it is stopped and 0 when it is running fine.

How can I check the status of the Modbus?
local ClickState = mc.mcRegGetHandle(inst, 'Click/rc');
local ClickRC = mc.mcRegGetValue (inst,"Click/rc")
I've tried both of these as well as variations of this and other API calls with no change.  It all returns 0. 

Am I using the right API or do I need to do something else or add something to this?

Getting the backlash out mechanically is absolutely the best way to do it.  Removing backlash in the software is just like a bandaid... it just masks the problem.
If you have a good quality ruler, use that for your calibration.  Get an extremely fine point tool in the spindle and move it from 0 to 20 and try that.  It should get you pretty close across 20" of travel.

If you have the ability, calibrate it to a longer length.  The longer, the more accurate.  I use a dial indicator to calibrate axis on our machines, but I always check to be sure it moves further accurately.

Mach4 General Discussion / Re: Mach4 Homing and Machine Coordinates

« on: July 14, 2021, 11:32:05 AM »

I think your issues lies with you hitting the zero buttons before homing the machine.
That will cause your work coordinates (offsets) to change if they don't match the machine position. 
Since you don't have home switches, you should move to your desired "Home" location like you have been doing; then hit ref all.  Then you can set your work coordinates (Hitting the Zero Buttons). 
The soft limits don't care where you home the machine since it is all relative + or relative -.   What it does care about is where the program "thinks" it is relative to the soft limit position.  So if you zero the axis before you home the axis, it will update the work offset (the position shown in the dro) to reflect the referenced machine position.

So try this:
Open Mach4
Move the table to your "Home Position"
Hit Reference All
Zero your Axis

See what you get once you do that.
