Run a stepper from 2 DM542 drive

Ok what you need to do is the following.

Approach whoever it was that gave you this task and explain to them that you are way over your head. Also that you have attempted to obtain some advice your lack of knowledge does not put you in position to assess the advice.

Now there is no shame in this. One of the controllers mentioned is worth a couple of grand. I do not want you to be responsible for messing things up if you make a mistake. We all do.

The best and safest solution is to get an electrician in, this is not electronics any capable electrician will be able to perform the wiring. Yes it may cost some currency, but is the wisest way to progress. I fear the actual wiring of the relay contacts to the various signal sources may prove to be overwhelming for yourself.

So it’s time to fess up, be honest and get some actual on site help. Sometimes that is just the way it is.

I honestly think this is the wrong project for you to begin on. Others may disagree and you are quite welcome to disregard my advice.

All in all I wish you the best of luck. Last of all if you do this yourself work slowly and check for correct operation as you go. It is easier to deal with one mistake at a time.

Exactly. ...and if I knew about his ignorant attitude I wouldn't have wasted my time on him. Being proud about skipping classes is the ultimate proof of stupidity. I'd be ashamed of asking to be spoon fed if I had the chance of learning and gaining knowledge and had the mental ability to read and understand. It's a different thing compared to someone who has learning disabilities but fights and tries to understand things.

You don't know nothing about me. Writing this kind of messages only prove your stupidity and this came with the normal package of arrogance. I skipped courses because I need to work to support myself in Uni. Asking questions is normal. Receiving this kind of responses is NOT. I was thinking the reason of this forums is to help and learn from each other. I was wrong. People like you makes this forums bad. Big muscle and mouth over internet are not good. If you have something constructive to say, say it, otherwise shut up.

This is the attitude that proves the previous post.

How did you manage to wire your project with so little knowledge ?

Did you wire the mains yourself ?

Have you taken precautions to ensure there is proper grounding for the mains ?

Have you taken steps to have the mains side checked ?

It is not just you that are at risk if the wiring is not done correctly.

Mains electricity is not something to be blase about.

Yes one may ask questions, but one must also be prepared for answers and additional comments they don’t like.

Is not much of a project. I bought this fiber laser (I also have a CO2 laser and CNC router) and quite quickly realized that I need to find a way to automate the focus problem (which appear mostly when you change the lenses - every lens has a different focus - distance between part to be engraved and lens). After I found a device which do that (has a sensor for measuring distance) I realized I need to find a way to use the original software (which requires a homing procedure at start up) and the new device. I was told I cant use both and initially I was thinking to use 2 stepper drivers with the same motor. I took the advice give by some members (more experienced than me) to use the same driver with the same motor with a 4 pole relay (never worked with relays). All I need to do is hook up a relay with a 12V power supply (which is already there). Simple, but what kind of relay. I was asking that because I was thinking to make a PCB for all of this. With the relay and step/dir on the same board. That was my project. Nothing related with mains. I have some experience with electric and electronic devices, but all is at newbie level. I build a CNC controller and run into trouble with spindle and VFD noise. Dean (Jazz) was kind and helped me to understand the importance of star connection. All is working now, safely for over 2 years.
I asked some stupid questions, I know that, but to receive this kind of answer is harsh and I learn my lessons, not to ask anymore.
When the relay will show up I will connect everything with some led's first ofr proof and after that everything will be moved inside the fiber enclosure.

Thank you for your help

Actually, you just proved my point. Even if you had to work, nothing prevents you from reading first BEFORE asking very basic questions. I helped you out all the way... and you call me stupid. I didn't skip classes and read the books. I have also programmed professionally during many years and even designed and developed both hardware, firmware AND software during the years, and believe it or not, I even have several inventions with my name on them... but I am the stupid... I actually like to help, but only those who are willing to learn and are not ignorant. Being proud of avoiding books is in my opinion ignorance. The arrogance is your attitude towards the criticism you received and the way you reacted to that criticism.

You did not understand nothing. I did not call you stupid. You stated that about me, first. There is a word The clever give up first, so I will do just that. Take care.
