General Mach Discussion / Re: Tangential Control

« on: April 12, 2006, 09:44:24 AM »

Hi,

If you want to cut a slot from point X0 A0 to X50 A90 then the code would be.

G00 G90 X0 Y0 Z25. A0    (MOVE TO START POINT)
Z1.                                 (RAPID TO 1MM ABOVE WORK)
G01 Z-1. F50.                   (FEED 1MM INTO WORK)
X50. A90.                        (FEED 50MM IN X AND ROTATE 90 DEGREES AT THE SAME TIME)
G00 Z25.                         (RAPID AWAY FROM WORK)
M30                                (END PROGRAM)

General Mach Discussion / Re: Help! Mach 3 (and 2) Pulse Frequency and "Dbl Plse" not stable

« on: April 12, 2006, 03:02:21 AM »

This sounds a bit like a problem I had with a dongal, my CAD software used a hardware key on the LPT port and a software driver, even with the dongal removed from the port the software still messed about with the data stream to the port.  I had to remove all traces of the driver before all was well.

General Mach Discussion / Re: M processor Laptop

Hi

This may not be what your talking about but its worth noting.

a lot of the newer laptops and some desk top systems use a 3.3 volt parallel port not the normal 5 volt one.  My mitac laptop just makes the motors judder. The same configuration on my desktop works fine.

Another thing I found out was that if you have CAD software that uses a Dongal, even with the dongal removed from the LPT port the driver software is still in the system and can't handle the speed of data to the port.  Mine caused all sorts of erratic movements until I removed all traces of it.

Mach Screens / Fanuc Look-a-like screen

« on: April 11, 2006, 11:13:39 AM »

Hi,

has any body got a turning screen set that looks like the fanuc 6T,11T or 18iT, all the Mach ones I have seen so far are way too complicated and over cluttered.  A nice basic screen is all I want.

Thanks

Graham.

Forum suggestions and report forum problems. / Re: Auto refresh

Thanks for that, I know about these options, I was after something to in effect press the F5 key for me.

I have my computer on all the time and wanted it to update the index so every time I pass it I can see if I need to stop work and have a look.

Not that important, it would allow me to do more work and less playing.

Thanks

Hi,

Is there a way to make the forum auto refresh so all new topics are shown as they are posted.

General Mach Discussion / Type of limit switch to use

« on: April 06, 2006, 03:10:05 AM »

Hi All,

I have some proxy switches NPN 5-30 volt with a 2mm sensing distance.  Can anybody give me a reason why I should NOT use these as limit switches.

Thanks

Graham.

How accurate is your 7.30" measurement?

Hi,

could it be the speedstep technology stepping it down for some reason?

Hi,

have you done a Ctrl+Alt+Del to look at the running processes, look and see if one of them is taking all the processor time, or if you are running out of memory.

Graham.
