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.

Hi,

I use a CTX touch 35, 15" part number PV500.

No special programming just plugged it in and everything worked.

You could use a setting jig something like the picture.

Make the jig from 1/4" alum plate and bolt it to the machine table anywhere, then clock it square to the axis.

The 1/2" hole is a setting hole so you can clock it at the start and set X and Y zero at this point.

Then have G54 set at -12" and -6"

The 3 off 1/4" dia pins then locate the work in the correct place.

The drawing is in metric by the way.

I'm not sure Mach3 supports this but on most controls you can enter 'G92 A0' into the code and it will zero out the A axis.

General Mach Discussion / Re: Serial Toolchanger Macro

Hi Dave,

Look at comment below in the code.

What version of Mach are you using?

Older versions of Mach3 needed CR+LF on getfifoentry(), I think Art was going to change it at one point,  it may be worth trying if you can change your output from the toolchange code. It may still be on the to do list.

Thanks

Graham

Select Case tool

Case 1
message "Changing To Tool 1"
Call sendserial ("t1d" & Chr(13))

(what are you getting with this bit below, is it showing any characters, if so the next call to getfifoentry() will be empty)

While getfifoentry() = "None" (what about a & Chr(13) here)
message getfifoentry
Wend

if getfifoentry() = "t1s" & Chr(13)  then
message "Tool 1 Selected"
SetCurrentTool( tool )
End select
else
Message "Tool Change Error"
end if

Hi,

Are you getting anything back at all?

Are you using handshaking?

If you want you can send me the macro and I will take a look at it.

Graham.
