Hi,

this problem happens when my code is running canned cycles (as G83) and press the feedhold buttom.
My feedhold button executes this macro

'FeedHold
DoOemButton(1001)
While IsMoving()
   Sleep (100)
Wend
SetUserLED(2001,1)
 
This routine works great when holding during a G0,G1,G2 etc, but when feedholfing a G83 the movement actually pauses but the Ismoving() never returns false, and the loop never exits

Any clue about what can cause this behavior?

Thanks

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

General Mach Discussion / Toolpath representation of drill operation
« on: April 02, 2010, 04:00:36 PM »
Hi,

Im currently writing a hole wizard for my screenset that allows to create hole patterns.

I have notices that the toolpath is not very clear when doing just drilling operations. it just shows the vertical feeds and the rapid moves, but it is not easy to spot the drill position that way.

Is there any way to make the toolpath windows show something like a dotted circle at the bottom of the drill or anything that can help represent better the drill toolpath, specially when viewing from the top?

Thanks

General Mach Discussion / PWM to RS485 spindle speed interface
« on: April 01, 2010, 12:49:38 AM »
If anyone is interested, I wrote an AVR program for a ATMEGA48 mcu to read the Smoothstepper spindle speed PWM and convert it to my VFDs RS485 protocol.
It can read from 0 to max rpm with 50rpm increment.
It can easily be modified to fit other VFDs that accept rs485.

If you want it mail me to pamafe@gmail.com and I will send schematics and code.

Regards

SmoothStepper USB / Problem when stopping execution
« on: April 01, 2010, 12:33:32 AM »
I had this problem many times. I would like to know if everybody has the same issue or am I doing something wrong.
I have a smoothstepper running my router.

Lets say that I have my machine references and zeroed and I start the program execution. I notice that something is going wrong and cant wait for feedhold to compelte so I push STOP (not e-stop button, just stop) in the middle of a move. The machine stops immediately, but all references are lost. My zero position is lost, and machine coordinates are no longer valid. I can even trip into a limit switch if i jog.

My guess is that this happens because the stop tells the SSto halt immediately, but SS does not communicate back the exact position where it stopped so Mach does not know wjere it stopped.

Is this a known issue? Can it be solved?

Thanks

Flash Screens / My flash screenset with touch and wizards
« on: March 31, 2010, 11:05:16 PM »
Hi,

This is the screenset Im currently developing for my router. It has some wizards integrated because I preffer to program in Actionscript than VBScript.
The actual screenset is 1280x1024. There are many features im planning to add. Im currently working on the teach/mdi screen
Please fell free to make any suggestions and critics.

Thanks
Pablo

Flash Screens / My custom touch screen & Wizards
« on: March 31, 2010, 10:19:20 PM »
Hi,

This is the screenset Ive been working on to use with my router. It has some embeded wizards because i rather program them in actionscript than VBScript.
Its still a work in progress; I included the features I use most often.
Please feel free to make any comments and critics.

Thanks

SmoothStepper USB / Is there a way of feedholding faster with SS?
« on: August 30, 2009, 01:43:46 AM »
Hi,

Im doing some bench tests on SS and Match before installing on a real machine.
Running a simple demo code I have noticed that it takes the SS 3 or 4 seconds to feedhold when I press the button.
Watching the SS data monitoring window It seems that it empties the buffer before entering hold state.

Is there a way of telling SS to flush the buffer so it holds immediately?
Are there any OEM codes or commands that are specifc for SS?

Thanks

General Mach Discussion / movieclip over toolpath display
« on: August 27, 2009, 03:08:30 PM »
NOTE: I already posted in the flash section where this topic surely belongs, but since I dit not receive any replies I decided to replicate it here to see if It is read by the most experienced users to at least confirm that what Im asking cant be done

Hi,
I have tried to create my own flash screen for mach3 and found some problems I dont know how to solve:

1) Im using the smart labels toolpath_mov and gcode_mov as in Mach Nation to show gcode and toolpath. The problem is that they seem to be always on top, even when I put something on a layer above them.
What Im trying to acomplish is to display a dragable popup keyboard to enter values, like in Mach Ultimate Screen. Anyone knows how to create a movieclip that shows over the toolpath display?

2) I want to write my own flash gcode display, but I cant find any doccumentation about how to interface to mach (where to get the gcode lines from)

3) Is there any doccumentation out there that shows all fscommand arguments used by the flash plugin?

Thanks in advance 
Pablo
