General Mach Discussion / Downloading the Mach3 Tutorial videos.

« on: February 16, 2009, 09:30:28 PM »

Hi all,

Just wondering if someone can assist me, I have been trying to download the Mach3 Tutorial videos, but cant get them to work.

I would like to be able to use them as a reference while Im actually using the machine, but it is not connected to the internet.

Is there a way I can download them and watch them in something like Windows Media Player. The files I have downloaded dont have sound after I convert them.

Any help would be appreciated.

Thanks to those who helped with my MPG project. It now works fine.

Thanks again,
I have successfully got the MPG to work using the transistor system, I had trouble getting the correct resistor value to provide the values needed,  so I went back to the Tranny idea.
I am still having trouble with the Glass Scale, maybe I need to retest my circiut, but will spend more time on it later this month.
Thank you all for the info on Screen 4 etc,  and also for the ongoing help and suggestions from you all.

Hood,
Thanks, Yes I mean I dont even know what screen 4 is or where it is.
and sorry, but what 'Sticky' ?? has the OEM codes.
I feel like a dunce, but I dont have much to do with programs and such, I just use the machines.
Hope you can help,

rogerbsstt.

Sage,
Many thanks for your comments. I will check the transistors temp as I go, perhaps I will also try some other resistor values as a backup just in case of a problem with the trannys. The MPG data specifies the outputs at min -.5v at -1ma, to max 7v at 5ma on the signal wires A & B.
From what I see the Mach3 doesnt care if the signal is HI / Low or Low /Hi because in the MPG config setup there is no Hi / low choices as in other config inputs and I guess Mach3 just reads the changes.

One last thing I need to resolve is how do I get my glass scale encoder to display on the 4th axis DRO in Mach3. In a past response HOOD mentioned changing the 4th axis OEM code to an encoder DRO. He stated it can be done in screen 4. I have no experience with programming and cant find a screen 4 that show the DRO. Can someone please explain in simple steps how to do this.

Thanks Again

Sage, Hood,
Thank you for your previous advice, the 4K7 resistors gives a max 2.89 v Hi at the pin and .2v Low, and the unit works OK. but after checking the Hi / low volts as suggested, I tried using a transistor to replace the resistor. I used a CBC327 (TO-92h) semi-conductor, (sorry I really dont what the correct terrms are), connected the emmitter(E pin) to the 5v and the Common(C pin) to the board 13 /15 pins, the A & B MPG signal wires connected to the central (B pin). When I checked the Hi / Low volts I got 4.84v hi and .21v low at the board.
The MPG works the machine so I think this appears to be an answer to finding the correct resistor to raise the Hi v to over 3v.
Please advise me if you can see any problems with this set up.

Thanks,
I will check those values.

Sage,
right on the money. I fitted two 4K7 resistors across the 5v and 13 / 15 pins and the MPG now works. GREAT STUFF!
I can get a 1 step movement on the X axis of .0021 mm. I am stoked.
THANKS to HOOD and you for your suggestions.
Merry Xmas from Australia, and happy NEW YEAR to you all.

Gentlemen,
thank you all for your comments.
The CNC4PC C10 breakout board has pulldown resistors on all input & outputs according to their documentation.
I will try all the ideas offered in the next few days.I have a second parrallel port on the computor.
Sage, is the pullup resister you suggest a 4.7 kilo ohm value.?
Any further suggetions will be welcomed.

again Thanks

Hood,
Thanks,
I have a second port in the computer so I will try it,

Thanks
