Hi all,i have MKS DLC32 V2.1 and have a problem with fire.
I have same power also 20%pwm and 100% pwm.
Whit this configuration,the tube fire automatically without wire IN (amperometer 12mA)
Besides a common ground, there are only two control signals to the lps. That is laser enable (usually the L terminal, where low is active) and the pwm power control signal (IN).
I tried to look up your laser, the best I could come up with is this oneā¦ Is this the one you own? This one looks like it has a Ruida controllerā¦
If you have K40 type with a āpotā control for power, the pot wiper is usually wired to IN with one side to 5V and the other side of the pot to ground. The PWM would go to H on the lpsā¦
thanks for reply,my machine is voiern 4040 and i want send a power byt lightburn no amperompeter
This is the same information that is in your profileā¦ A link is always better than a nameā¦ It appears there is more than one typeā¦
The one I found comes with a Ruidaā¦ Iād think it had some other controller in it if you moved to the MKS DLC32.
Iāve given you the technical data of how to set it up ā¦ what can I do from here to help?
Itās clearly wired incorrectly.
Do you have a knob to adjust the power on the laser?
A mA (miliamp) meter is dirt cheap, I suggest you install oneā¦
You probably want a 30mA meter.
this is my machine
I donāt understand your wiring.I think is like my wiring in 2Ā° last photo
This looks like a K40 typeā¦
It is not like your 2nd photoā¦ The MKS in all liklyhood has only one conection, besides ground to the lps.
The meter on your ādashā that you dial up the power, should be going to the IN terminal and the PWM output should go to the H terminal.
Follow?
is not a k40 but 50w voiern and the 2Ā° photo itās my psu on my machine.
for this:āThe meter on your ādashā that you dial up the power, should be going to the IN terminal and the PWM output should go to the H terminal.ā you mean, S->IN,TTL->TH?
You have to have a common ground to send signalsā¦ The MKS only has ground and the PWM output going to H. The IN terminal comes from the dc voltage indicated on the console.
What wire went to the IN terminal before you upgraded the controllerā¦? Iād suggest you put it back.
This is the connections to an LED laser from your board.
The V is for the supply voltage, G is ground and S is the ttl pwm signalā¦
S ā H
The K40 uses this kind of technologyā¦ It doesnāt matter what size tube it hasā¦
If you paid less than $1500 USD for it, itās a K40 type.
in refer of my psu 2Ā° image,what is the wiring?S->TH,TTL->IN?
There is only one connection to the mks board to the lpsā¦ You keep adding themā¦
The G and V outputs have no use for you here, if the system is grounded then only the S signal is used.
You photo 2 is wrongā¦ You have ground from the MKS to the L inputā¦ This is the laser enable, so it will fire whenever the IN terminal goes high.
The connector you reference is labeled S-TTL-V ā¦ it is a ttl output (0 - 5V) The pins on the connector are actually S-G-V ā¦ the TTL reference you use isnāt there ā¦
Some of these you need to answer my questions, or I canāt help you any further.
The IN output of that board goes to the IN terminal of the lps and the S output goes to the H input of the lpsā¦ Those are just how to hook it up to the lpsā¦
Makes sense?
Heading back to bedā¦ good luck
Your help has been invaluable to me. Hereās how it worked:
MKS->PSU
S->IN
TTL->TL
V->TH
Thanks for all
You should not apply V+ to the H input. It should work without thatā¦
If itās working, greatā¦
Take care
without V+ iāts like 2Ā° photo and not work correctly,havenāt a power modulation.
With V in TH iāts ok.Thanks for all
