Title: mach3 connect 2 Z axis
Post by: komar1970 on October 18, 2011, 07:44:12 PM
I just started to build cnc router with 2 Z axis , Please tell me how I connect the 2 Z axis to work separately. My  cnc driver  is g540

Did you ever get a single axis to work correctly on your mill using the G540?  ???
Now your venturing onto a 4th / different machine.

not, it seems that it is not possible I have no more power, to annoy myself I have submitted myself, with gecko g540 I worked already 4 years , and never the driver worked well.

 I know that someone will say (This guy just does not know how to set the cnc machine!) This is not true! , For 4 years there is no possibility, so you did not learn what's come on in this.
Is there any problem, but I do not know what , and the worst part is that no one know what the problem is

I want to check once more g540, so I decided to build this cnc router with 2 Z axis. the only problem I have is if I will be able connect the 2 Z axis separately
I mean 1 to Z axis and the second to A or to B  i dont know

what are you building, any why?... and I see that as a programming nightmare.

MACH3 only has 1 z axis. IF you want to build duplexed version you are on your own.

ok I see that there is no other option, it means I have to disconnect from one Z axis  motor cable , and connect the other motor. I am building a cnc router with plasma ,on one Z axis  will be plasma on the second Z axis spindle.
and that is why I wanted to work 2 Z axis separately.
does this mean? after working with plasma, machine will have to go to zero, rewarded the cables and start the spindle axis?

Then your not using a ROUTER your building a dual headed plasma cutting machine. That I would think you could do with one Z axis head and two digital height controllers. But your on your own with that.

Maybe you could create two separate profiles.
One for Plaz, and one for Rout.
Then you would only need 1 Z axis.
Just jog the one you are not using clear of the work area.
Possible ?

YNN,
  I think maybe you misunderstood.

I mean 1 z per config.
Sorry for any confusion :)

also thought so myself , but I saw what plasma is doing how it comes out . I thought it better to spend a little more and do  on the other side secend  axis

bad only because you can not do 1g-code for everything

I'm building a router with 2 Z axis.
I plan on using SwapAxis() during toolchanges, based on the tool number. Numbers under 100 will use one spindle, and numbers over 100 will use the other. I think you also need to use G52 for the second spindle offset. SHould be able to handle this in the M6 macros.

It can be done, but there possibly be a lot of macro programming involved, and as was mentioned, you'll be basically on your own.

MACH4 is suppose to have multi z axis support.

Just hafta wait, (;-) TP

I wrote to someone, he has Emc2 and controls the two axles

Now it's 4 years, ??? and another machine, and using who knows what computer , BOB, etc you are using. ::)
Frankly, if you haven't solved the other three machines, or even addressed what was suggested in the other posts.....
you will end up at the same place only with a more complex situation to deal with. Then numerous posts and time will be spent trying to help
you and you won't do what was suggested.  :( Thus no closure on anything and the story will continue. Probably will go onto a 5th machine and start all over. ;)

Doesn't seen all that different than running a drill or impact marker on a separate Z axis.  If the second Z axis ends up being "A" then just use A instead of Z in CAM when you want to command that axis.

Another way is to put the secondary tool on a slide with an air cylinder and use an output to control the cylinder.  Air on and the tool moves down and below the plasma torch.  Air off and the tool moves up above the torch.  With the secondary tool in the down position, it becomes the active tool.  With the secondary tool in the up position, the torch would be the active tool. Either way, you're using normal Z commands on both.  You'd have to apply an offset to any code intended for the secondary tool, but that can be done in CAM.

you know what the problem is in my English, I can not write properly. I wonder all the time on the gecko 540 I know this driver, I do not want to buy next gecko 540 , I just want to check it  ,surely my next driver will g203v and c11


I will not  pushing money into something which can not be set

which is not to understand  ,  I know the plasma gives the dirt because i  will bulid 2 Z axis

Guess I should have said: "I never seen that statement", sorry for missing that detail.
