General Mach Discussion / Re: Another NetMos 2nd paralell port thread

« on: July 07, 2007, 08:29:08 PM »

Hi,
Sometimes it happens, that address in the device manager is not the same as in the bios. I have had similar problem ones, and when I changed the value at bios settings, everything worked fine. Remember, that's the Windows.

General Mach Discussion / Re: Simple toolchange position

« on: July 04, 2007, 07:25:18 PM »

If I understood you, you want to get the spindle to the proper position for the tool change and then continue the program? There is option at the settings screen where you have to enter tool change position. Then you have to enable tool change in the config menu. When g-code find T*, program stop and you have to press 'go to tool change location" button, then your spindle shall take desired position. After you change tool, pres cycle start and that's it.
Hope this help
Cheers

Off course you have to connect battery gnd to the lpt pins 18 - 25, as this is the way of closing current loop.

Hi,
I have similar problem with LPT. As I set the address in device manager, I didn't check it at the bios settings. I have lost few hours until I saw that the address at bios differs from the same at the device manager.

General Mach Discussion / Re: Only one direction pin! Please help.

Hi Jolbe,
You have to separate dir pins, not just step pins. And one suggestion, you should use pins 2-9 for step/dir control, because this pins can sink and source much more current (10 times) than pins 1, 14, 16 & 17. In many cases these pins can not supply enough current for activating optocouplers at the input circuit of controllers and you may have just one direction, or losing steps. If you have opto's at the input of driver, they need approx. 10mA, witch is too much for LPT pin 1.
Cheers

Thanks Brian.
 I would like to play a little bit with VB, as i am closed to C++ and assembler, so i think that it wouldn't be a problem. ModIO is my definite choice, but i have to do in next few days, and w/o it this time.

General Mach Discussion / Mach & Multi Tool Head

« on: June 03, 2007, 07:30:49 AM »

Hi,
I have to retrofit some old Biese Rover 7 which has boring head with 7 tool holders. These holders are mounted on the head and are pulled down/up by pneumatics via 7 control signals. I was wondering What is the best option for control this function by Mach3. Is there possibility to define tool change macro so it can output BCD Code to Outputs #4-6. Then I could build BCD to 7 segment decoder and so on, control 7 tools.
The second question is for feed override button. I have reed that there is possibility of connecting encoder directly to LPT port, and enabling this function?

Cheers

General Mach Discussion / Re: Message line="Safe Z turned off-ignoring safe z move" but it's not turned o

« on: May 19, 2007, 08:10:48 PM »

I think that I saw an option somewhere (but can't remember where) to select between absolute/relative Safe Z position, so if you select it to be relative, the problem should be solved, and tool should be raised above material for the safe z value first, then go to y0, x0.

P.S. It would be nice if somebody could remember where is this option.

Hi,
Thanks for a such quick answer. Yes, I know where to find G & M code list for Mill, but it differs from the TURN codes.
