General Mach Discussion / Re: Reference switch issue

Gerry,

I can understand this if as on the picture of my first post there is room to go just beyond the "reference metal block" and then stop. I would call this a "side" approach.

I have another switch where there is a "frontal" approach, in the axis of the reference switch. In this case I would fear the behaviour you describe, as the process would be :
- approach, the LED is OFF
- about 1mm from the switch, the LED goes ON
- Beyond the switch, after a crash I presume, the LED would go OFF and the motor would stop then.

I would think that the motor should stop when the LED goes ON. The alternative is to modify the position of the reference switch, but this would be strange. I am building a German kit that is clearly designed with this frontal approach.

In attachment the view of the X axis. The table comes close to the reference switch, frontally.

One attached picture show the reference switch (without the table). The second picture shows the table. The inner side (grey/blue) of the table travels in direction of the switch, frontally.

Regards, Philippe

Dear all,

I am trying to set-up reference switches. These are magnetic ones and go ON when a "reference metal block" comes nearby. (See picture "BF 20 version 1 59 Z.jpg")

It was done with the automated set-up of Mach3 (demo version), using a screw driver to trigger the contact. Each time a nice beep was heard.

With the machine in operation, each time that the "reference block" comes nearby, the LED of the reference switch goes ON, BUT the motors stop only when leaving the reference switch, as soon as the LED goes OFF.

I would prefer to see the motor stopping as soon as the LED is ON.

Here are "diagnostic" screens :

1) Approach. The LED is OFF.
in attachment see file "Reference before and after the switch.jpg"

2) switch above the reference metal bock. The LED is ON.
in attachment see file "ReferenceLEDon.jpg"

3) switch just beyond the reference block, the motor stops when the LED goes OFF.
in attachment see file "Reference before and after the switch.jpg"

If I do a RESET, I can jog in any direction.

I have tried to fiddle with Active Low inputs, without success.

Regards, Philippe

Dear,

I have found a better solution and a "feature" of Mach3

I have two keyboard definitions on my PC : US Qwerty and French Azerty. For one or another reason, Mach3 loads the US Qwerty keyboard as it starts, even if I was working with French Azerty before, say using Windows Explorer. Usually Microsoft applications like Word or other, including freeware, do respect your initial keyboard set-up.

The solution is to start Mach3, load your keyboard of choice, press RESET. All input field work so far I can see with all required characters and signs, on all Mach3 screens, including the software jog. A "real" jog is also working fine without any tweak. You can always check which keyboard is being used on left hand side of your Microsoft Windows toolbar.

The only strange thing :  if you are looking at the "Diagnostic" screen and you press the "Go to Home" key with the jog, a Windows Explorer window pops-up. On other screens, like "Program Run", no issue, homing works perfectly. I am happy that this "feature" is a minor issue and I can live with.

Regards, Philippe

Hood,

this is not really satisfactory for a product that has a world-wide potential.

Anyway, I have found a trick for non QWERTY keyboards :
- I use the jog (TAB key) to manipulate X Y Z directions with a click, as Arrows and PgUp PgDown do not seem to work work with my Azerty keyboard
- I use the NUM numeric keyboard in order to enter figures and eventually the decimal point. Input of Gcode also works this way.

Note for non Qwerty users : it seems that Mach3 forces the use of some kind of Qwerty at start-up. When Mach3 is opened, you just need to select and click on your specific keyboard on the Taskbar (below your screen on the right hand side) and do as above.

Thanks, Philippe

I am using a French AZERTY keyboard on my PC instead of a QWERTY

This keyboard works well with Notepad or Word, not with Mach3 :
- only the NUM numbers are recognized
- the decimal point is not recognized nor on the NUM keys nor on the main keyboard
- the numbers on the top of the keyboard are not recognized.

Is there a special set-up enabling to manage specific keybaord on Mach 3 ?

Regrads, Philippe

Messieurs,

utilise un clavier AZERTY qui n'est pas reconnu par Mach3. Le problème majeur est que les chiffres ne sont pas reconnus  (du moins ceux de la partie supérieure du clavier càd MAJ + le chiffre choisi)

D'autres programmes style Notepad ou Word reconnaissent ce clavier sans problème.

Il semble que Mach3 soit configuré pour un clavier QWERTY US .

Un conseil ?

Philippe
