Mach4 General Discussion / Re: G-code execution from screen button.
« on: October 08, 2017, 11:58:38 PM »
Hi zarass,
just one other thing....your machine pics are great but because they are embedded in the text they open and download each and every time
the post is opened.

A better method for pictures, particularly detailed high resolution pictures is to add them as an attachment. They show up then as thumbnails and the
reader of the post can download and view as he wishes or not as the case may be.

When posting with the text window open you'll see 'Additional Options...' to the lower left of the panel, click on it and you can browse to any file
including jpegs that you wish to attach.

Hi zarass,
had a couple more thoughts that may help you along. I don't know what screenset you are using, my one is now somewhat personalised but is
still very close to wx4.set which is  one of the standard sets that ships with Mach. Given that it is personalised I've given it a new name.

If you note the five buttons just below the DRO block <DeRef All Axes>,<GoTo Work Zero>,<blank>,<Machine Coords>,<Distance To Go>. I don' know about you
but I only use <GoTo Work Zero> and <Machine Coords>. Because the screen is that full of stuff already what I would do is reuse the unused buttons and
the one unassigned one for the three buttons you require. Cheap and Cheerful, Down and Dirty is my motto!

Actually adding buttons and LEDs and things is quite fun but you don't really have much room to play with. I've found you have to shrink a lot of existing
buttons and other elements just to squeeze in another button or whatever it is that you want.

If that sounds Like a reasonable idea to you then its just a case of using the screen editor to change two buttons to your preferred name and assigning a name
for the one unused button. You would need to clear any event script or functionality of the two buttons you are re-purposing.

Hi,
what sort of PC are you using? What version of Windows is it running? Have you run DriverTest.exe?

Hi,
the resolution of the display in the link is 0.1 foot and an accuracy of 20 thou? Does that sound right?

Hi,
Mach has a variable that it uses as its commanded speed, even if you don't set its still there.
Just as an experiment try setting S to some funny number, 15995, for instance. If this number
crops up on Machs screen then you will know whether its using the index and measuruing the
speed or just reporting the programmed speed. It can do both.

General Mach Discussion / Re: problems with machining holes and Z axis
« on: October 08, 2017, 05:03:35 PM »
Hi,
yes its calibrated, thats not your problem. You need to shift it up and down a small amount repeatedly to see if
the Z axis is gaining or losing steps. Leave the calibration as is and do the test I suggested.

Hi,
if the 'steps per' are being correctly saved then calibration is not your problem. You have an issue with the Z axis.

Run some tests, without a workpiece:
<zero z>
MDI g0 z10
g0 z0
g0 z10
g0 z0
g0 z10
g0 z0

The Z axis should move up and down 10mm. Do it do so? Does it end up in exactly the same place it started? Note
I would expect the DRO to go back to zero but if the axis is faulty then it may not physically return to where it started.

Hi,
on your motor tuning page when you set the 'steps per' and so on are you hitting <save> as you exit?

Hi saschko,
Mach may not have control of the speed and you or your program may not have specifically issued an Snnn command but there is a variable
inside Machs core that it will use whether you chose to update it or not.

Hi,
two preliminary things to be done.

1) Set up a folder somewhere on your machine that will have the three Gcode files. Your buttons will be calling these files so they will
need a fixed filepath and the files themselves need a unique name.

2) You need to set up three buttons on your screen. Exactly where you put them is up to you. If you are not familiar with editing the screen
then you need this:
http://www.machsupport.com/wp-content/uploads/2014/05/Mach4%20Screen%20Editor%20V1.0.pdf
For ease I would put them in the same 'container', means that you don't have to chase all around looking for the code. Given that you are
modifying the screen you should save it as a unique file so when you update Mach the standard screen set doesn't get overwritten.

Once you have these two items in hand then the event script of each button will be populated. Two instructions likely to be of use are:
Code: [Select]
rc = mc.mcCntlCloseGCodeFile(
number mInst)
and:
Code: [Select]
rc = mc.mcCntlLoadGcodeFile(
number mInst,
stringFileToLoad)
