No.

Sorry.

It might still be possible to do what you want to do, though.

And you can indicate a way to? For example in a post i read you are able to run MDI command and at same time jogging an axis .... but I'm not able to .... I think you use touchy when I use axis.

these is right? and where is the trick? Because normally MDI can run in MDI mode not in manual mode .... or proble is all here? so MDI can run in manual mode but axis interfaces can't permit?

and in your opinion haluy interface can permit to run MDI at same time with jog operation? (obviusly not on same servo).

Well, first, what do you want to do? At a slightly higher level than you have described so far.

I would like to do a single assen with an MDI command .... and at the same time make jog movements (for example) with a second axis ... simultaneously or not depending on what logic classicladder decides ..... my CL it already makes both the MDI movement and the jog movement desired mon it is not possible to do the two movements simultaneously ..... one movement must necessarily be MDI or in any case gcode ....

actually I use axis gui ,,,,

I still have no idea what you are trying to achieve....
You have decided that the answer to your problem is to run MDI and jog at the same time, but perhaps there is another way?

Anyway, take a look at "external offsets" which allows jogging a moving axis.

x axis -> movement x0 f2000, x20 f1000, x25 f500, g4 p1, x0 f2000 m30


y axis -> y0 f5000, y-50 f3000, y0 f5000, m30

I would like to run these two routines at any time regardless of whether one is active or not. Both must end once started. It must be possible to start a routine even if the first is running.

as you can see the second routine can be a jog movement because it only makes a back and forth movement of the same quality ..... so the request for 2 gcode .... or to start an MDI and simultaneously use the jog.


To start the whole thing I use classicladder .... only today I can't run the two things together.


I had also thought about eoffset .... only that I need a sim_encoder because in reality I have nothing to "chase". In addition it is complex to set for a forward and backward movement (it would take 2 eoffset to "swap" one for the forward and one for backward movement) so that I am looking for an alternative solution.

an axis is a 50N (small) press (x) and an axis is a translator that moves an object back and forth. The two are not related so they cannot fit on the same gcode.

So is it clearer?

thanks & regards

sim-encoder is actually of very little help.

What I think you would use would be simple_tp to send an accelleration / velocity controlled path to a waypoint, and then conv_float_s32 to convert that position command into counts to be consumed by eoffset.

Or use extrajoints, and control directly with simple_tp (or similar)

and on ini file extra_joints can be declared as normal joint?

Any how seems the right suggest .... thanks a lot.
