Title: Laser M10P1
Post by: Snues on April 26, 2016, 05:22:59 PM

Hallo

So da mein English nicht gerade das beste ist hoffe ich im Deutschen Forum auf Hilfe.

So um was geht's bau gerade an einer Co2 laser Maschine rum und bräuchte unterstütztung mit dem Befehle M10P1 / P0  sollten den Laser bei jeder Achs Bewegung ein oder aus machen... Probleme gibts bei den Einstellungen......

Ein Member (tweakie) von hier hat das gut gemacht nur kann ich mich nicht verständigen mit ihm ....

Der Befehl M11P1 schaltet Ausgabe # 1 - wenn der Laser-Trigger mit dem Pin # verbunden ist, die 1 bis Output # abgebildet wird dann der Laser eingeschaltet wird.
Der Befehl M10P1 wird ausgeschaltet Ausgang # 1 - wenn der Laser-Trigger mit dem Pin # verbunden ist, die 1 bis Output # abgebildet wird, dann wird der Laser ausgeschaltet werden.

Hoffe das hilft.

Connections wrong?

If it helps, I will attempt to explain the circuit’s requirements…

1.   This pin is taken TTL(H) and TTL(L) in accordance with the pre-set Mach3 PWM (spindle speed) output signal.
2.   This pin gates the laser ON and OFF and is controlled by the M10P1/M11P1 commands. The laser will only be on when this pin is at TTL(L).
3.   This pin is signal Ground (GND).
4.   This pin requires a weak pull-up to +5Volts (to provide the necessary Vcc for the opto-transistor) and this is generally already provided within the laser PSU’s (Active Low) trigger input. This pin actually switches the laser ON and OFF

Hello Tweakie

I have no designation ( TTL TTH ) in the description of the laser power supply.
I think the TTL TTH with my power supply " WP " is right?
What is "pull-up to +5Volts" ?

Bernd

From the diagram you have posted...

Pin 3 of your laser PSU is TTL(L) and it will incorporate the '+5 Volt pull-up'

Hello Tweakie

sorry i am confused :( i not understand

Pin17=Dp25(lpt)
Pin16 (output1)= laser pin3
Gnd=Gnd
Pin16 (laser drigger)= pin16 (lpt)

Hey sorry for bothering you again, but may i ask you the last time for help...

Can you pls just connect the pins of the SubD25 with the pins of your control system and further on the pins of the control system with the laser control terminal? pls just mark the connections with lines in the attachted picture

thx in advance i would be really glad for your final assistance...

Because there is always more than one way to do anything this is just a suggestion...

hey thanks you very much . I have the circuit built up and the Gauge shows 0 Volts on the display.... Is this okay??

I have uploaded a Video of the problem.

Hi Bernd,

You are making progress.  ;)

Set PWM Base Frequency to 100 (spindle setup)
Set Output #1 to Active Low (output signals)
Set Clockwise (M3) to Output #1 (spindle setup)

You need to add spindle speed to your Gcode (S0 = minimum PWM ; S100 = maximum PWM).

You need to be using Mach3 version R3.043.056 or later.

If you wish to test the circuit / setup without it being connected to the laser PSU then temporarily connect the components shown in red.
With this and when Mach3 is set-up as described then the commands…
M3
M11P1
S100     should indicate 5 Volts
S50       2.5 Volts
S0         0 Volts

Etc.

Hey Tweakie


I assembled everthing like you told me. I have version R3.043.066 and adjusted all the things as you texted me.
To get everthing right, should i connect a 5 volt source (4,5 also possible?) as +pole with the 10k , the -pole with Gnd and place the gauge in between?

Bernd

Title: Re: Laser M10P1
Post by: Tweakie.CNC on June 15, 2016, 11:13:59 AM

4.5 Volt would be OK, connect as shown in the diagram (+pole to the 10k and -pole to GND).

Hey Tweakie

Last time to be totally sure...is it at the 1st picture a 10k resistance and at the 2nd one a 10k potentiometer?

You are correct sir.

Hey Tweakie

I have set up the curcuit layout without the power adapter and 4,5V battery and it works. But it shows me at  OV at S100, 2,25V at S50 and 4,5V at SO, shouldn't it be the other way?

Bernd

Title: Re: Laser M10P1
Post by: Tweakie.CNC on June 16, 2016, 07:49:18 AM

That sounds correct.

When using the TTL(L) input to the laser PSU 0Volts is maximum laser power output and 5Volts is minimum laser power output.

However, to reverse the voltage slope just change the Step Low Active state of the Spindle (Config. / Ports & Pins / Motor Outputs).

Hey

Thanks for your help, now really the very last question, is it mandatory that the potentiometer has 10k? cause i don't have a 10k one

Bernd

Title: Re: Laser M10P1
Post by: Tweakie.CNC on June 18, 2016, 11:46:56 AM

It is not mandatory. I would think any value between 1K and 22K would be OK.
(I use a 10K, 10 turn, potentiometer with calibrated dial).

Hey Tweakie,

i tried today the laser as we discussed with the paper... unfortunetaly there was no shot from the laser, even though the circuit works with the battery. With the button at the power adapter, a laser-shot is possible, so it should be a problem with the circuit. I took 2 pics of the wiring, may i ask you if you recognise any mistake?

Green = GND
Black = m10p1

Hi Bernd,

I can't say for certain but there does not appear to be any mistake with your wiring.

Obviously you need to set the PWM signal near maximum, the potentiometer to around 10%, turn on the spindle (M3) and apply the M11P1 command.
