Thanks zealous.
I tried it and I think it will work.
I had thought of something similar but since LED805 does not activate when feedholding in a canned cycle I discarded it. But now I found that feedholding in a canned cycle does not allow to jog, so it may actually work

check the config/port and pons/motor outputs
to see if your dir and step pins are enabled and correctly configured?

check if by mistake you press the online/offline button?

General Mach Discussion / No feedhold led during canned cycles?

« on: April 07, 2010, 11:39:32 PM »

Hi

I have a led on my screen that is on when the machine is in feedhold state.
For this purpose im using OEMLED805

I have notices that it works when im cutting a part, but when I press the feedhold button in the middle of a Canned cycle like G83 the execution pauses but the led does not turn on.

Is this a bug or am I doing something wrong?

Thanks

Hi,

Im writing my own screenset in Flash.
When a part is feedholded,  I jog off and then return before continuing.
Im aware of the usage of the remember and return oem buttons,however the "preparational move" screen is not enough for my needs (specially because is not made for touchscreen) and I would like to replace it.
For this I would need to access the Remembered position, either via a DRO or a Param.

Does anyone know if this is possible? I think no dro exists that holds the remembered position, but maybe there is an internal parameter that im not aware off.

Thanks a lot for your help
Pablo

Flash Screens / Re: My flash screenset with touch and wizards

I did some research about nesting and found that it requires to implement some algorithms that look pretty difficult, specially for actionscript.

1) Finding the centroid of each nested part
2) Find a No Fit polygon
3) Recursive genetic algorithm for the sorting sequence.

For the time I have now I dont think i can make it. Maybe i would try to write something in C# and invoke it from flash using fscommand.

In the meantime, I added a wizard list feature to the screenset so instead of running only one wizard generated code at a time, they can be added to a list an run all toghether.
They can also be deleted from the list, and when clicked they get you to the line of code where that particular wizard starts

The following image shows one surfacing operation followed by three circular pockets

When you say that change their value, does this affect the toolpath result or is it just a rounding issue on the dros?
What happens if you return to the run screen? The values remain changed or they return to the previous values?

Maybe you can override motor speeds setting this parameters in a macro. Never tested it.

"VelocitiesX" = X MaxVel from motor tuning page (SetParam as units/second. Mach will multiply X60 for display in motor tuning as units/minute.)
"VelocitiesY"= Y MaxVel from motor tuning page (SetParam as units/second. Mach will multiply X60 for display in motor tuning as units/minute.)
"VelocitiesZ" = Z MaxVel from motor tuning page (SetParam as units/second. Mach will multiply X60 for display in motor tuning as units/minute.)

Thanks for your comments

There are a few thing that would need changes before I can share the SWF

1) The ref button runs a routine to square my routers gantry. I have to change it to an external macro so anyone can replace it for their own
2) My router does not have auto tool changer.
    I have all my tool information entered into my cam.  I dont want to keep it duplicated and synchronized in mach. So I changed my cams postprocessor to make it send tool information to mach. This way each time a new tool is needed a flash popup appears that shows a picture of the tool with its requested parameters such as material, diam, outside holder length, etc.

3) For the auto tool zero, the plate location is currently hard coded to my machines position


About the nesting and writing wizzards (billman311)

Both would be very nice, specially the nesting one, I use it all the time.
I would need to learn some more about opening and processing dxf files (or maybe I can nest directly NC programs by rotating and offseting them)
 I will add it to my wishlist

Thanks for your comments

As soon as it is properly debugged I will make it available to the Mach community.
I have to make some changes to make it more customizable
What wizards do you think are the most commonly used?

So far I added

Surfacing
Straight Cut
Circular Pocket
Rectangular Pocket
Drilling

General Mach Discussion / Re: Toolpath representation of drill operation

« on: April 02, 2010, 06:22:20 PM »

I found a way that at least partially solves the problem
I use the block delete feature. I make the wizard generate the code with arc movement to show the drill and then on the run button I enable the block delete

This are the pictures of the drills as shown this way





Thanks
