General Mach Discussion / Problems with "ref all home"
« on: October 06, 2013, 01:28:33 PM »
Hi, I been working on this for days now, and I am loosing my mind.

I know this is going to be something so simple and stupig but I cant figure it out.

in short,

- when I hit the "ref all home" button.  the Z axis traveling down slowly (as I assume it should)
- I hit Escape to ignore that axis, and want to move on to the X or the Y, but what is happening, is after hiitting the ESCAPE the first time, the whole thing stops moving, it never moves on to the Next axis.

In the online video, "homing, limits and offsets" the person doing the video shows how its showing his Y in reverse, hits escape, and the X is in reverse.  he never mentions anything about the Z.

so, for me, I am perplexed, its only the z that is moving.

anyone please,  put me out of my misery!

Hey gang,

I am sure this isnt really the place to post this but, it kind of is.

What I am looking for is a site, a guide, multiple sites, multile guides,  stuff you found that helped you ...

I am looking for a start to finish, newb / intro  here is what you need to do to get from design to chips.

I have seen a similar video for a plasma cutter, (i will post it later)  I am looking to share other information.

who knows maybe we can get something stickied if we collect enough information.


I am reading tons, watching tons of video's and learning curve could be  bit easier if I could find it faster.

that said I am loving this stuff.

post your tidbits, maybe even suggest "a'ha" moments you had.

ie:
 -how to zero.
- how to make the letter Z on a block of ...
- what software got you to ....
...

Thanks

Very cool, thank you.

here is the information as I have it :

General Mach Discussion / Question about the Scale of my DRO.
« on: October 03, 2013, 10:07:03 AM »
Good day,

I have question that I cant seem to find anywhere, I am sure its something I am doing, but You guys are the people to ask :D

so, I am trying to set my soft limits, (in metric) and I suspect my bed can move about 1000mm left or right..

but when I do so, my DRO says its moved 4.19

I suspect that the scale is wrong, or its using imperial to measure.

I am pretty sure its moving about 7-10 inches, but I am pretty overwhelmed with all the options, I was hoping you guys could help me out here.

Hi Menglor,

I would use 6 limit switches and it will make no difference to Mach3 operation if they are connected to separate inputs or if they are all connected in series to just one input - they can still be used for homing and limit.

Tweakie.

I guess what I need to do is  change the pin numbers for x ++ , x--, x home, y++ ...  set them all to pin 1?  if I understand what your saying, this seems to be the logical choice.


I am a software tester by profession, man I would soooo HATE to have to write a test plan for this thing,  its SOOO many things to play with :D

so in my Continuing research, I think I may have figured out where I goofed!

I found this article:   http://www.cnczone.com/forums/gecko_drives/75368-g540_wiring_diagram_dummies.html

now, I realize this is kind of what I am trying to achieve, but it confused me because they only used 3 switches (4 if you count the A axis)

But I used 6, but after thinking about it, I am wondering Did I need to use 6? or is 3 enough, and just using the Soft limits in Mach 3 to not let it go over other end?

Good day all,

I been lurking for a while, even fixed a few problems using the forums, but This one has me kind of stumped.

I still havent cut anything yet, I am done my conversion, and I installed my limit stops, but after watching one of the video's, I think I want to change it.

I was half hoping someone here has done it, or can point me down the right path.

My hardware:
 - X2 Clone
 - G540 Gecko controller and 3axis steppers
 - cnc Fusion x2 kit.

So basically, I have wired up my mill using 6 limit switches all in series in a NC State, so if any trip, the whole thing stops.  and that more or less works.

But after watching one of the video's,  I got the impression I might get better control and better zero'ing capability if I wired up the switches independently.

But as far as I can tell, I believe the Gecko only has 4 inputs (at least that I can tell) and I need 6 to do it properly.

is it better to wire up the 6 switches independently? or can I achieve this zero'ing capability differently?
