M574 X0 Z0 Y0 S0 ; Define active low and unused microswitches
what does this actually mean in plain english please?
or where can i find this sort of thing?
I have NOpen switches so S0 is right?
does X0 mean its unused so I should have X1? indeed 1 for all of them?
really this stuff doesnt explain anything…..

http://reprap.org/wiki/G-code#M574:_Set_endstop_configuration
I just found this page recently, and everything is spelled out pretty well there
Parameters
Xnnn Switch type for X axis
Ynnn Switch type for Y axis
Znnn Switch type for Z axis
E Select extruder endstops to define active high or low
Snnn Logic level
Example
M574 X1 Y2 Z0 S1
This defines the type of endstop switch or opto sensor that the printer has for each axis: 0 = none, 1 = low end, 2 = high end. The optional S parameter defines whether the endstop input is active high (S1, the default) or low (S0). Intended for use with boards that provide a single endstop input for each axis that may be used for either a high or a low end endstop, such as the Duet. Supported by RepRapFirmware. On delta printers, the XYZ parameters refer to the towers and the endstops should normally all be high end. For the extruders endstops, S0 is for active low and S1 for active high. M574 E S1 select active high (used when endstop is a Z-probe, needed from v.1.14) - for all extruder endstops -
Have a look at the M574 description:
http://reprap.org/wiki/G-code#M574:_Set_endstop_configurationThe S parameters says if the endstop is active low (S0) or high (S1). Active high, normally closed, are safer as most failure modes result in them failing as triggered. Assuming you have active high end stops this example will use S1 but you need to check what you have.
So if you have endstops on X and Y, but a probe not an endstop on Z, and the endstops are triggered at X Min and Y Min then you would use
M574 X1 Y1 Z0 S1
Or if you have endstops on all 3 axis minimum then:
M574 X1 Y1 Z1 S1
If you have endstops at Max instead of Min then:
M574 X2 Y2 Z2 S1
You should also check M208:
http://reprap.org/wiki/G-code#M208:_Set_axis_max_travelAs that is useful for setting what Max (and Min if <0) distances each of the printer axis are.

So I have Xmoving and homing perfectly.
Y moved fine but when I hit home it moves the wrong way, back towards the rear of the printer and not forward.
I cant see how to fix this, so how do I fix this please?
-
I have set M208,
M208 X190 Y190 Z170 ; set bed dimensions ssj
-
programming, i knew this would be the hard part ;(
-
ok so homey.g was 200 when it should have been -200
So Y is now good.
Z moves the right way, (up) but ignores its end stop switch, ho hum, led lights so switch and circuit are ok.
so Y has stopped doing the fast initial movement….weird.....so Y is now broken....odd
-
Ok so the web config tool's default was a probe and not a switch removed that so Z is done.
-
So to "fix" Y I set the -200 back to 200, tried it, was backwards again. Set it back to -200 and saved and its works. I am finding this behavior odd, buggy in fact.
-
Ok so basic homing is probably fixed, really the config tool was more of a hindrance….imho.
anyone have some good tutorials i can watch / read please? thanks.

read through the entire reprap.org wiki, it has a lot of information.

I'm really feeling your pain with this….I really struggled with all this having never seen anything like it before.
It's a matter of taking a deep breath, asking a few questions here and going through the wiki slowly from start to finish.
Problem is (and absolutely no offense meant) is that David and the guys do this so much for a living that they have trouble "dumbing it down" for beginners in the way they describe things. You've just got to ask again...they probably roll their eyes, but you can't see that happening on your screen and they don't start shouting, so it's all good.
Mine's (converted Zortrax) working a treat, and I'm just printing up a matching set of bits (fan shroud/cable chain mounts/etc) and it's done and dusted.
Web interface and wifi is awesome.
You'll love it when it's all done.

The web ui is just neat. I understand, as a linux admin used to command line stuff sometimes users seem to ask, silly Qs. Sort of got used to it, its just hand holding until their confidence builds. There is just so much info to take in it overwhelms at times. The docs seem to reflect their assumptions a lot, typical developers, live and breath something then get confused when users flounder a bit, LOL. Hard to do as I do it in work so I know.
Its also some considerable nerves, I spent a lot of money for this board, I dont want to bugger it!Anyway I am also documenting this and taking pictures on how to do it so it will be available and critiqued I am sure!
