General Mach Discussion / Re: 2nd parallel port card issues

« on: February 02, 2010, 07:10:56 PM »

Unfortunately, I threw away the box and the cards don't really say anything. The driver says "Multi-IO adapter".
Also make sure that in the Ports & Pins configuration you have enabled the inputs & outputs and that the right port port number ( 1 or 2) has been entered. It should be the same as the one you have enabled.

Make sure you also checked the enable port box.
Also, to make sure it is the parallel port. Try using the diagnostics tab. Ground some input pins on the 25 pin connector and see if the LED's come on.
I'm also using cheap parallel cards and they work. I bought them at Compusa.
Are you sure you typed 0xCC00 ?

Good luck

Mach3 and G-Rex / Re: Driving a galvo head with Grex possible?

Maybe you can create a macro. I believe with the VBScript you can define a time as small as you need. It could be like an M150 and in could be something like:
x=time()
while time()-x < .004
wend

General Mach Discussion / Re: Turn on off without stopping

Wil,
I scoped the signals. With the regular M3 and dwell set to zero, the spindle output turns on 0.5 seconds before the first motor pulse.
With M11 the spindle output turns on about 1.5 msec before the first motor pulse. This is with a 25000 Hz kernel speed.
the P1 after the M11 or M10 refers to the output it controls. i.e. P1 controls output1, P3 output3, etc.
Thanks to iggy for all your info.

Hood,
What makes you think I didn't do a search before posting my question? Of course I did! But in the 2 posts I found I couldn't find an answer.
I f you don't want to help please don't bother answering with silly answers.
Anyway between me and othe member of the forum we are figuting out how these misterious M10 and M11 work.

Regards

wil,

The laser beam is about .008"at about .050" from the work area.
I think the M10 & M11 commands should work. The laser is RF driven, so I expect it to turn off almost immediately (microseconds) after the signal goes off. I'm going to try the M10 commands. I'm also going to scope the signals to see how everything really works.

Thank you. But that is not it. I already have all dwells set to zero.

General Mach Discussion / Turn on off without stopping

« on: April 22, 2008, 04:15:12 PM »

In another post I saw people talking about commands M10 and M11. For example: M10P1.
I seem to understand it has something to do with turning on something and moving without a delay.
Would anybody be so kind to explain what those commands are and how are they supposed to be used?
I'm using mach3 to control a laser cutting machine. Right now i use M3 to turn on the laser and M5 to turn off. I also use the PWM output to control the power of the laser. It works OK. except, there is a little delay from the laser turn on to when it starts moving and also a delay from when it stops movint to when the laser goes off. For instance:

S50
M3
G01 X5 Y0 F40
M05
M30

I would really appreciate any help.

Regards

Mach SDK plugin questions and answers. / Re: New Plugin Available - XBox360 Controller

« on: March 30, 2008, 05:56:29 PM »

I've installed the xbox plugin. But when I start mach3 it says: "plugin defective"
I am using a Logitech xbox controller vendor id: 0x046D , product id: 0xC216.

Could this be the problem?
