Is Axis Mapping possible?

[akeller]

Hello everybody. Here is Alfred - another restless retired SW engineer who has started playing with Hobby CNC and has discovered Auggie. I just assemblied my motor controller with PoKeys57CNC controller and have successfully configured my XCarve (from inventables.com) in Mach4 Demo.
Now I have my first question:
Is it possible to map and configure the X/Y/Z axis to a different motors then 0/1/2, which seems to be the default in Auggie. Silly enough, i wired my Z-axis to motor 0 on PoKey, and the X-axis to motor 1.
Regards, Alfred.

Hi Alfred:

  At present ..no. Though its not something that would be hard to add , I havent gotten there yet..

Another question, perhaps same topic.
Where, how and whether is it possible configure a master slave axis, becaus on my cnc i provided 2 motors for the x axis. Is it in pokeys config or can Auggie do this for me. As newbie not quite sure, even not as I looked just at the setup video.

Hi :

  Kin of part of the same thing, now that someone has asked for slaving and mapping, I will aim
toward it. Cant promise when but Ill see how it fits in..

Thx

Hi Art,

perhaps you need not to program everything, if it is possible to make a work around by scripting.
I am too unaware to know just now, but if I would make a new panel with the special Jog Buttons, which pulse two axes e.g. axis 1 and axis 8 simultaneously? Do you think, that is possible, then you have not to deal with such item in Auggie programming directly.
That would be a more flexible way, because I could assign what I want for my machine. I wonder only, whether this is a way to go. Dont put to much effort in this topic, if we can solve this.
Other more ugly walk around would be to map 2 axis by hardware, eg. fast contact doubler.

NOT ugly to do it in the hardware ....
I have to correct myself  ;)

Its more easy than I thought with posteps: I checked the driver chip, its a Texas DRV8825 like today used in many stepper drivers. The advantage is, that it has an open collector output for pulling down in case of error and 100k input resistance for step and direction, so to make a clean 2 Motor axis you simply can put 2 connectors parallel on one ribbon cable coming from pokeys. The error output willworke, even also the inputs. Cabling should look like this:

Pokeys:          Postep X1        Postep X2
1-------------------1----------------1
2-------------------2----------------2
.                        ...                     ...
.
.
10----------------10----------------10

I will use crimp connectors and crimp them onto the ribbon cable.

WARNING: Please wait for electrical checking, I will answer in the next 6 hours, because I have to do some mechanical work first. I then will post some Photos.

To Alfreds problem: Why dont you swap the 2 connectors??

[akeller]

My problem is solved - as you suggested - by swapping the motor connectors on the Pokey.
I had also to swap the motor configuration because X and Z have different u/unit on my CNC.
I was just spoiled by Mach4's option to map axis to motors, but i agree that this is not the most wanted feature in Auggie 
Thx, Alfred.

Hi Art. Just stumbled across this post.

I re-configured my machine. Previously I jumped the second Y axis motor to the same driver. Under this setup Auggie worked.

Now I have a slave motor for the second Y axis and moved the mapping "out of numerical order" due to cable length from the stepper drivers to the board.

x=0
y=1, slave 2
z=7
a=3

I don't think it's possible yet to set the Slave Axis in Auggie or? Or change the default motor mapping from I assume X-0, Y=1, Z=2?

At the moment I cannot get Auggie to work with my current setup.

Any chance you have done any work on this? (Based on comments you made previously in this thread)

Thanks,

Scott

Hi Scott:

Hmm, I will have to more deeply dive into Auggies code to refresh my memory to
answer this. I have a recollection of code I added that allows any axis to
be any other axis, but I cant recall the specifics or if I turned it on in the
release. I use Auggie for photos and such and run it on two different machines
but I haven't had to remap on either one so I cant really recall the
specifics.
I will be away from the code as I have to enter the hospital for surgery
today and will not be back for a week or so. Remind of this question when
I return and I will post the details of what's possible. As I roughly recall
there is a script command or something to allow you to remap..
Is there any reason Augie wont run on your current machine? If its
a problem related to crashing or something let me know and Ill
see if I can help you there as well.

Thanks
Art

Thanks Art. Good luck with your surgery! Hope all goes well.

Currently Auggie won't run on my machine at all. The Z axis won't move, X axis moves when it shouldn't and only 1 y motor will fire. The setup runs fine in Mach4.
