General Mach Discussion / x axis not moving when using one computer, does when using another

« on: November 29, 2011, 08:46:11 PM »

I am trying to use a different computer to run my machine. It works perfectly on one computer, but when I switch to the new computer the x axis  doesn't work. The pin-outs are the same. I even tried using a different set of pins and it still would not move.  Everything is identical and the y,z and A axis work fine.

My question is: Can anyone think of a setting or anything else that might be keeping the x axis from working?

I'm hoping that the problem is not the computer, but I'd like to be sure it is not something else before I take the computer back to the place I bought it from.

thanks,

General Mach Discussion / Drivers spiking like crazy -pulse rating too fast

« on: November 28, 2011, 11:12:03 PM »

OK, I tried the special drivers and it still seems my pulse is too fast. Art mentioned some sort of remedy for this. Anyone willing to help? 

My motors are jumpy and some don't move at all. When I plug into a different computer everything works fine. Ports and pins are identical. Any ideas on what's wrong?

Never mind folks, I figured it out.

How do I disable the external e-stop?

G-Code, CAD, and CAM discussions / More questions on calling sub-routines

« on: November 27, 2011, 09:00:15 PM »

Can someone post sample code for calling a subroutine?  I would also want to quantify the number of times it repeats.  Is it just a matter of typing m98 and then following it with my subroutine, and then adding L ##  for the number of times it repeats, and then ending it with M99?

Thanks,

General Mach Discussion / Re: Using M7 without interrupting G01

Here is the test Gcode and the BRAIN. Load up the brain and run the Gcode. It move until it gets to the target point then shuts off the mist. At the next corner the Mist turns on with the Gcode and then when it gets to the target point it shuts off the mist, etc,etc

f100
m7 g01 x44.18
m7 g01 y-30
m7 g01 x0
m7 g01 y0
m30

Hope that helps, (;-)TP

Sorry to be obtuse, but what is a "brain" and exactly how do I load this code into it?

thanks,

Here is the basic block of the code:

f500
m7 g01 x9
m9 g01 x44.18
m7 g01 y-9
m9 g01 y-30
m7 g01 x35.18
m9 g01 x0
m7 g01 y-21
m9 g01 y0

This is repeated several times. If you can re-create this using your recommended technique so that there is no pause during the M7-M9 cycle, it would be great. Thanks for accepting this unusual request!

It is a simple bit of code. Basically it does a rectangle shape repeatedly. The m7-m9 commands occur at the beginning few centimeters of each corner of the rectangular path. I am not familiar with the technique you mentioned so I'll need instructions aimed at a relative neophyte.

I guess I was not entirely clear. I need to have the M7 and M9 commands happen WHILE the cutter moves along the X or y axis. It must start and stop while the mill head advances without pausing. Specifically, I need the M7 command to happen at the beginning of an G01 command and then the M9 command to happen before the end of the g01 run, IE without stopping the movement of the mill head along the X or Y axis.

I am not using the M7 and M9 for cutting fluid, -it is for a different application. When I add the M7 or M9 commands anywhere in the code, the mill head stops momentarily while the commands are carried out. Is there a way to avoid this?

I would like to use the M7 and M9 commands without pausing or stopping the g01 travel. What is the correct code order to achieve this?

Thanks,
