Hi Buchanan,

Not a dumb question at all.

Quote
One thought occurs to me: last night I left the workshop in a hurry. I just flipped all the switches off on  the power board, didn't shut Mach 3 down or the computer.

It is as you suspected - Mach3 saves it's settings to the .xml file on shutdown. If the shutdown is not completed correctly Mach3 will load a previous .xml file (settings) on  next start-up.

Another dumb question . 

I come to start my computer this morning and I thought to check my motor tuning.  What do you know , but my pulse width has reset to 0 uS.  Well, perhaps I did not save the settings , so I do this.  Then I thought: I will test this out. So I restart my computer and  and check my pulse width again and it has reset to 0 uS. Now i must be getting old, grumpy and suspicious. I check out all the changes Tweakie recommended and they have all changed back to the old settings. I am now just as old but more grumpy and suspicious.

So I reset all the changes back to Tweakia's  and I  start to restart my computer. This takes a little long to do, so, rather than restart , I shut down Mach 3 and reopen it. Now  all the changes remain correct.  So I then restart my computer, now everything  remains correct.

I am now old , grumpy suspicious and baffled!

Is there a proper procedure to make sure all settings are saved.

Hi,
the TinyG will not work with Mach, 3 or 4.

The principle activity of Mach is a Gcode interpretor, secondarily but still importantly, it is an IO program. In the early days when the parallel port
was the only option for hobbyists it also provided the code for the PC's CPU to be the motion controller. These days most people use an external
motion controller like the UC100 or a Smoothstepper. The parallel port still works and is free but it can be problematic and restricts the choice of
PC's you can use.

Probably the cheapest way forward for you, if you wish to go the Mach track at all, is a UC100 or a PMDX-411 and a Gecko G540.
The UC100 or PMDX-411 are motion controllers, they plug into a USB port on your PC and produce output signals on a DB25 plug familiar to
anyone who've used a parallel port in the past. They are about $100. The Gecko G540 is a combination stepper motor driver and breakout board.
It accepts signals from a DB25 socket, just perfect for the UC100/PMDX-411, and has four DB9 plugs for four steppers and a bunch of screw terminals
for home/limits/spindle etc. The G540 can handle 50V, not earth shattering but quite enuf to make your steppers take notice. You can set the motor
output current by soldering a resistor of the right size into your DB9 plug, easy. The G540 is $300. As I've said before and others will endorse Gecko
make reliable gear, I'm sure you can find cheaper but I doubt you'll find better.

With these two items and the licence cost of Mach you are looking at an investment of about $600. You might wangle a way to do it cheaper but probably
not by much and certainly with less manufacturers and forum support when it comes time to get it to work.

The advantage of Mach over the software that you've already tried is that the Gcode programs which run it are 'industry standard', or at least as standard
as it gets, it copies Fanuc Gcode, about 80% of the industrial market. So you could go to a half million dollar machining centre and see and understand the same
code that runs your router at home. Also all the CAD/CAM programs which are used industrially you can now use. Be warned a lot of them are VERY expensive,
Mastercam, one of the oldest and most capable CAM programs costs about $20,000 and $2500 a year! There is a new player out there though which is transforming
the hobby CNC scene, its called Fusion 360. It is a CAD/CAM program written and maintained by the Autodesk, the same company who bring us AutoCAD and
HSMWorks two very capable and expensive bits of software, but Fusion 360 is free! Even better than free is its damn good too. Even if you decide not to go Mach3
you can still download and fiddle with Fusion 360.

You'll have to decide whether Mach represents a good investment for you. You can download and experiment with Mach3 and Mach4 without cost. The Demo versions
are fully featured but can only do tiny little jobs before you have to reset it. My personal preference is Mach4 being the new and developing version.

I have no idea what a smoothieboard is...I have Mach thanks and don't need any of the pretenders!

Thanks Craig.

The nema 23's that My router table uses seem more then adequate but I guess if I wanted mad speed I would need something bigger then thenema23's and  tinyG. What I like about the tinyG is I can control the amps going to the motors right from the board. You raised a few more questions though. The tinyG setup I have uses ChilliPepper to send the gCode to the tinyG and for me that is bad since it requires internet access or a nerd genius to figure out how to download some files and tweak those files to work offline. So would mach3 or mach4 even work with the tinyG? Keep in mind all I have is laptops from windows 7 to windows 10.

I also have a smoothieboard I can use for one of the upcoming projects. Am I correct in assuming it too is a motion controller and 4axis driver?

That has been run from the screen_load_script.

From the menubar click on operator and then screen editor.
Once in the screen editor you will need to highlight the top of tree in the top left of the screen then click on the lighting bolt icon in the box below it, you should now see the screen load scipt.
you will find the part of the script that is doing the msg box on line 58 if you are using the stock wx4 screenset.
