- In this video I am making a voltage divider with Opto Isolator for CNC plasma cutter, then I will use it for height control with arduino.
With a new method I developed, Mach3 USB control cards that do not support THC will also have THC, stay tuned.
Bu videoda Opto İzolatör ile CNC plazma kesici için voltaj bölücü yapıyorum ardından arduino ile yükseklik kontrolü için kullanacağım.
Geliştirdiğim yeni bir yöntem ile THC'yi desteklemeyen Mach3 USB kontrol kartlarında da THC olacak, takipte kalın.
THC I made using this circuit with Arduino

you are the best 🤩
Mehmet ustam elinize emeğinize sağlık teşekkürler. videolarınızın devamını bekliyorum. Kolay gelsin.
Great job thank you sir
maşallah güzel olmuş. bunu kesimde artık takipte kullanarak yükseklik kontrol edeceksiniz. devamını bekliyoruz.
Teşekkürler evet arduino ile z eksenini kesim anında yüksekliği korumak için kullanacağım, aslında daha önce daha basit bir voltaj bölücü ile yaptım bunu fakat kararsız voltaj okumaları yüzünden pek sağlıklı çalışmadı.

Ahh yes, great people doing open source again. THANK YOU A MILLION, building JD's plasma currently will integrate this into cheap parkside plasma cutter. Will maybe create video about it. :). Are you interested in spinning it with PCB design? Would buy it from you.
Thank you, there will always be wonderful people.
I just added the gerber files of the PCB to the Github repository, you can have them made by a company.
You're from the US check out @xt1200z1's comment below, he has 3 more of these so maybe he can send you one.
@@MehmetIbrahim thank you for info. I would love 24v version so would not need step down converter for opamps.
@@RokasSondaras The circuit draws a very low current such as 0.12mA, you can use it by regulating it to 12v with LM7812 before voltage input.
@@MehmetIbrahim thank you for this info, will incorporate this into PCB design.
Yesterday, in the simulation, I measured the current drawn by the LM358 only without the B1212S.
I just had the opportunity to measure the real circuit with B1212S. It drew 4.77mA current. This is not a problem for LM7812, but I am writing it for correction purposes so that my other followers can read it. Good luck.
If anyone would like this PCB populated with everything but the HCNRR200 I have 3 extra. When you purchase the PCB they make minimum of 5. I am in the USA would prefer to only ship in USA.
Nice video and great documentation! I would like to try this on my JDsGarage plasma setup. I am attempting to continue using a 3 in 1 HF plasma cutter (Amico CTS-180). Height is critical. I do have touch off for torch initial height setting before each cut, but would like to add the THC.
I have a question, why can't I use 5v instead of 12v? The LM358 and HCNR200 are okay with it?
LM358's They can operate at supply voltages as low as 3.0 V or as high as 32 V.
HCNR200 1 LED and 2 Photodiodes, they have different voltage supplies.
Recommended Operating Photodiodes Conditions 0-15v, LED are 2.5v at 35 mA.
However, in its position in the circuit, the HCNR200 LED fed by resistors and LM358 is limited to 1.56v 8.5mA. Photodiodes are 10.1v and 0.04mA.
Surprisingly, when I applied 5v in the simulation, the output did not change, so it is still 1:50.
The only thing that has changed is the 10.1v on the Photodiodes decreased to 3.09v
I think yes, it can be used with 5v, but B1212S should be changed and 5v compatible B0505S should be used instead, or alternatively, 2 different independent 5v supply sources should be used.
@@MehmetIbrahim Thanks for the explanation. My PCBs should be here this week!
hocam devam videonuz ne zaman gelir. Unutmayın bizi
İşlerim yoğun o yüzden zaman bulamadım bir türlü ama devamı gelecek sizleri de merakla beklettik ama günümüz şartları böyle ne yazıkki
Good morning,
Can I consider this voltage divisor as a 1/50 divider usable with the THC of the PROMA 150 SD SIGNAL/DIR model model
thank you for your reply
Michel
Hi Michel, as far as I know, PROMA 150 SD has an internal voltage divider, it can also be used with an external voltage divider and according to the information given, its external input is max 10vdc.
According to this information, yes you can use it. In my tests I got about 2VDC from the output with 100VDC from the input.
@MehmetIbrahim
Thank you for your answer
In fact I intend to use it with the MyPlasma interface module why?
Because I don't want to bring the HF into the electric cabinet
And I prefer to work with lower tension in the cabinet
So if you tell me 2V for an entered 100V
It must largely do it
Am I obliged to use the 12V of your assembly?
Thank you in advance for your answers and beautiful project finely completed@@MehmetIbrahim
@@michel54000 "Because I don't want to bring the HF into the electric cabinet" I understand the reason better now. Yes, I wouldn't want that either.
The circuit must be fed with a 12v power supply due to the HCNR200(Opto-Isolator) and LM358(Operational Amplifiers) components used, otherwise it will not work.
I did not measure the voltage range to be used for the supply. A different supply can be used, but I recommend using 12v as this will affect the output voltage.
Where did you buy the 30mh inductor ?

Sa abi mach3 kartından plazmanın gücünü ayarlama gibi birşey yapılabiliyor mu
Yapılamıyor ancak plazma makinesine müdahale edilerek ek elektronik derve ile yapılabilir mach3'te spindle için devir değişme çıkışları kullanılarak bu yapılabilir ama buna değmez
@@MehmetIbrahim niye değmez acaba
@@emreturhan2991 çünkü plazmanın gücünü genelde çoğu kez aynı tutuyoruz keserken 50cm sonra malzeme daha kalın veya ince olmuyor bir de şu var 80A ayarlı makina 3mm yi de 10mm de aynı amperle kesebiliyoruz incede daha hızlı kalında daha yavaş bir hızla kesiyoruz yani akım 10mm kesecek şekilde ayarlı fakat aynı ayarı kullanarak 3mm yi daha hızlı kesip zamandan kurtarıyoruz

Saya coba bikin rangkaianya,, saya simulasikan input 0-5v , outputnya kenapa tidak bisa 0-5v ya pak?
Ini beroperasi pada rasio 1:50, yaitu, jika Anda memberikan 100v pada masukan, Anda akan mendapatkan sekitar 2v pada keluaran, rangkaian tidak memberikan keluaran 5v yang konstan.
Outputnya antara 0v dan 5v tergantung pada inputnya
@@MehmetIbrahim iya saya simulasikan tanpa devider.. Jadi sebelah kanan dari devider, mulai dari dioda 5.1v itu saya kasih input 0-5v. Tapi outputnya tidak sesuai input ya pak?
@@bengbeng_cnc Tegangan yang Anda masukkan dari dioda D1 dan outputnya harus hampir sama.Anda memiliki kesalahan dalam simulasi.
Ini mungkin berbeda hanya dalam nilai mikro volt.

Greetings friend, some substitute for the optocoupler, or some other voltage divider since I can't find that component in my country.
please thanks
Hello, the alternative to HCNR200 may be IL300, why don't you get it from another country?
Thanks friend, I will take your recommendations into account 🙏
