Mach4 General Discussion / Re: lua error or is it
« on: September 14, 2017, 06:53:42 AM »
Hi,
I found testcount in the PLC script:
Code: [Select]
testcount = testcount + 1Reading the remaining code the script uses testcount variable to do certain setup tasks on the first pass of the PLC script
and not subsequent passes.
The fact that it passes the first time its run without error suggests that all is well. On the second pass however testcount has mysteriously
been corrupted and is now considered to be a nil value. What gives? Is there code in your PLC script which overwrites or otherwise corrupts
testcount? As you can tell LUA is still new and mysterious to me as well!

Hi,
I know what you mean, it does make it hard when the manual is so out of date.

It must be said that Artsoft have forged ahead adding new features and fixing bugs etc. While updating the manual is important it is a house keeping
chore rather than development which secures new customers and supports existing customers.

As an example, I don't know whether you've had a chance to look at the new PMC feature, a ladder logic programming tool, it's brill! All in all given limited
resources I support Artsoft's pursuit of development even at the expense of documenting what we've already got.

Another aspect of this issue is that the motion controller plugins can and do make entries in the .ini file and can be said to be part of Mach4 setup but
are in fact provided by the motion controller manufacturer not Artsoft at all. I can only claim to have any real experience with the Ethernet SmoothStepper
and the vast majority of the Mach setup is actually automatically made when you configure the ESS plugin. Warp9 do keep a pretty up to date set of
instructions which in effect covers 80% of Machs setup as well. My understanding is that other manufacturers plugins may emulate the same but in other
cases much less so requiring you configure the plugin AND mach4. Given the wide variance in treatment by different plugin manufacturers I can see
why Artsoft see the whole 'documenting setup procedures' as a challenge its always going to lose.

General Mach Discussion / Re: mach 3, motors will not run
« on: September 13, 2017, 11:07:23 PM »
Hi.
OK, the 'excellent' report doesn't mean that much, the real value of the test is the variance in pulse timing.

Do you have an Estop button on your controller? I imagine you do and if it works then the controller is
talking back to Mach which is good news. Do you have a manual for your control box?. Does it require
a charge pump signal? Do you have access to the DIR pins, useful to probe with a multimeter.

Hi,
kool, you got somewhere to start. I'm assuming because you don't mention a controller that your'e using a
parallel port.

Have you run DriverTest.exe. Do so and post a screen shot if you can.

Hi Dwayne,

I'm dumb as a Brick when it comes to programming
rather suggests that using Mach4 for all that stuff would be a challenge for you, it can be done if you have the fortitude for it and
you will get a real blast of satisfaction when it comes together.

and need multiple operators
No matter whether you use Mach or a PLC you don't want multiple operators fiddling with it so I don't think 'user friendly' is
really a decision making input.

In recent times a feature called PMC which is a ladder logic programming tool has been added to Mach4. It may be of interest to you.
Check it out.

General Mach Discussion / Re: Mach 3 keeps freezing
« on: September 13, 2017, 03:02:02 PM »
Hi,
USB is quite susceptible to noise, keep it as short as you can. Ferrites at each end help but adding one in the middle breaks  the 'antenna' length.

If it still gets on your wick buy an EthernetSS, they do much better in noisy environments.

Hi,
what sort of PC and what OS are you using?

Do you have an external controller or parallel port?

When you jog or MDI do the DROs change?

Does the Estop button work?

Have you downloaded the Mach Installation Manual and more importantly have you READ it? If you have may I suggest READ it again.
Second suggestion READ it a third time!

Mach4 General Discussion / Re: Another RefAllHome question
« on: September 13, 2017, 02:49:25 PM »
Hi,
looks like your sorted.

As I commented earlier you have lots of inputs available with the ESS and really no need to combine limits and homes the way we
did with PP.

Hi,

'Why does mach not back up after contacting limit'? Home LED activates at contact.
Mach4 backs off a home switch, not a limit switch and the LED does not operate on contact.

The LED activates when the homing sequence for that axis is complete, that is the axis drives until the home switch operates, the axis stops and reverses
direction and backs off until the home switch deactivates, travels the required offset distance as assigned on the Mach Home/Soft limits page, the machine
co-ord for the axis is zeroed and finally the LED is turned on.

Confirm on Configure/Plugins/ESS/Pins Config that the input you are using for your string of home switches is assigned the correct port and pin with an appropriate
name like 'home'. On Configure/Plugins/ESS/Input Signals the Motor 0 Home, Motor 1 Home and Motor3 Home should all have the same signal  'home' assigned.
On Configure/Plugins/ESS/Homing page set the approach and offset speeds.

Mach4 General Discussion / Re: Mach4 modbus plugin problems
« on: September 13, 2017, 03:59:42 AM »
Hi Keith,
haven't had any problem here with an earlier build.

I'm trying to replicate what your are doing:
1) Configure/Plugins/Modbus
2) Click Add NEW Modbus Connection icon top left
3) Name, Description and Type <Next>
4) Enter Serial Com properties, check 485 <Next>
5) Confirm <Finish> or <Cancel>


I have these three screenshots of 3),4),5)    Do they match what you see?
