Hi,
I have understood that it's a Xilinx but exactly which one ?
Could anyone tell me ?

Hi,
It seems that on linux it's supported a more cost effective board :

Does anybody has an ideea if it was any intention to implement a driver for this board in Mach3 ?

Finished Plugins for Download / Modified Video plugin
« on: August 09, 2008, 05:49:40 AM »
Slightly modified Video plugin. The web cam is mounted next to Z axis and takes care of distance between cam and spindle.

Hole application has been done to drill on a CNC pcb made using toner transfer.
Explanatory article can be found at http://www.dioda.ro/News/article/sid=21.html

General Mach Discussion / height scan map - engraving, pcb routing
« on: July 14, 2008, 10:19:50 AM »
I have seen this height probe sensor  :

http://www.boenigk-electronics.com/web/en/tools.html

and their cnc controller has also the capability to load a height scan map and compensate the Z axis.
Sometimes I do some pcb engraved and I have few friends which are engraving workpieces with irregular surface .

Such option would be very useful. Anyone has any ideea if this exist or how could be done ?

Hi,
I would like to enhance the video plugin and to add some offset values when the webcam is aside from the drilling machine.

I have tryed to wrote something like :

#include "CMyScriptObject.h"
CMyScriptObject scripter;

scripter.SetParam("X",0.001);

not working ?
what it should be ?
from where I should find those info ?

General Mach Discussion / Video Window plugin Issues
« on: April 06, 2008, 05:38:05 AM »
Hi,
I have mounted an web cam next to spindles to ease the finding of x0 and y0 coordinates.
I have found the following :

A. critical issues :
- image mirrored on X axis
- on mouse move the movement on Y axis is inverted

B. issues acceptable for a while :
- some times the arrow keys are not working
- when you check the mouse move the arrow keys are not working also
- doesn't remember scale settings

I have made a small video of my trials :
http://www.youtube.com/watch?v=ChmmySgO4kM

Is any updated version available ? Does anybody has available the source code for this plug-in I would like to try to enhance it.

Regards,
Daniel

General Mach Discussion / Arrow Keys +Ctrl +Alt +Shift
« on: April 04, 2008, 11:05:39 AM »
Hi,

In a previous version of Mach 3 the combination of any Arrow Keys + Ctrl or Alt or Shift was giving a different behavior on jogging  speed (smaller/greater speed or single jog step )
On newer versions this is not working anymore.
It is a matter of xml config file or this functionality has been obsoleted ?
I have tried a combination of an xml config from an old exe to a newer exe version but without clear results.

General Mach Discussion / USB output board instead of printer board
« on: August 03, 2007, 03:28:55 AM »
Hi,

Very soon the Parallel printer port will disappear (from laptop's is already gone).

I have seen that Mach is supporting only two external output boards : G100 from GeckoDrives and  ncPod.
Unfortunately both of those are expansive and their schematic and firmware closed.

Did someone considered to use a simple output board like this :
http://www.olimex.com/dev/images/PIC/PIC-USB-4550-sch.gif
http://www.olimex.com/dev/pic-usb-4550.html
 or even better http://www.olimex.com/dev/sam7-p256.html (SAM has a much higher amount of ram and 60mhz clock ).

Those chips have usb connection and their price is around few euros.

I would like to try to implement a very simple board like this having following functionalities :
- receive and send data trough usb port
- store received octets into a circular buffer
- send this data on a timer from buffer to output pins

This will ensure that data doesn't depend on variable transfer ratio of usb port.

If someone it is willing to help me and it is able to write the plugin that will drive this board please help.
I'm intending to make available for free the schematic, the firmware and most important to run the tests until is running.

Also if you have experience please tell me what could go wrong with this ideea !

Daniel

General Mach Discussion / Interfacing Mach3 with an external program
« on: April 12, 2007, 08:13:49 AM »
Hi,

Please tell me if there is a way to integrate Mach3 with an external program like is Dinamic Data Exchange ?

I would like to be able to open another program on same machine and to send movement commands to Mach using a protocol like DDE.
I have multiple applications for this functionality. One of them would be an advanced optical edge finder for example...

Daniel

General Mach Discussion / Stepper's spinning with glitch'es
« on: January 28, 2007, 11:12:31 PM »
Hi All,

I have installed Mach3 and I was trying to move my stepper motors (from HPLJ3) and drivers made with A3977 (like those from www.pminmo.com or CNCZone ).

I have configured and it seems to "work".
The problem is that motors are not spinning smoth (I don't know how to tell you because my english has only few words) sometimes are stucking for a very short time and after that they are continuing to spin normally and some other times are speeding up more than normally.

I have looked with an oscilloscope on parallel port and I have seen that the computer is giving the step signal in this way.

I have started Task Manager, I have ordered tasks after CPU time and I have seen that when steppers where stucking in the same time top 3-4 processes where changing between them. I have killed some processes wich I have seen that where consuming some processor. The situation has improved a little but not enough.

Could somebody tell me if this is normal and this is the way wich Mach3 normally works ? What I should try more ?

Regards,
Daniel
