Here is the first in a set of videos on laser controller wiring. This will be a very detailed series of videos. If there is anything you would like to see in the videos, please let me know since I am still editing and creating for this series (5/2/2021)
@@andrasravasz8491 That is awesome!! These comments really do engender a desire to make more of these videos. Thank you so much and keep up the great work!!
Thank you so much! I didn't know where to start and didn't know anything about cnc before I found your video's, and now I have built my own, so thank you 😊
Just some comments : - Heat shrink tubing for spade terminals and ferrules. With connections this close to each other you don't want to risk a stray strand of copper wire shorting things out. - Chinese powersupplies in general, I never use them unless I have opened them up and inspected them for safety (fuses, solder splashes that risk shorting stuff out etc, proper thermal grounding, the usual). And yes I have seen all of those things in 1 powersupply at the same time. - When possible for limit switches (if the controller supports it) use NC connections, one can debate the use of this but it will trigger the controller early in case of issues with the limit switches (broken switch, cable issues etc).
Thanks for the warnings and suggestions on improvements. I will definitely do these. The limit switch configurations are as per the requirements from Trocen documentation which is the supplier of these controllers. I'm sure there is a way to change this in software to invert but for this demonstration, I will leave it alone. Most of the other controllers also specify NO in their documentation. Many years ago, I use the same logic to configure as NC so the machine will stop in case the circuit opens for some other reason, but I only use this configuration on parallel controllers (which is becoming very scarce). I like the suggestion to heat shrink the terminals, but I am always very cognizant of careless whiskers. I will head your advice anyway since it will give some insurance and will also look pretty good. I must have gotten abnormally good suppliers for power supplies. I have only had a few issues in the 13 years dealing with Chinese power supplies. Thanks again.
@@PatrickHoodDaniel I was unaware of it too until the powersupply for my 3D printer failed and I opened it up to repair it. I suspect it was wavesoldered because the plastic wrap around the capacitors was literally melted at the base. Also it had multiple splashes of solder on the top side (where there wass not even any traces or solder mask) held on only by sticky flux residue. And when I got to checking the fuses it got completely dodgy with two fuses bodge soldered in parallel. It was clear they ran out of the appropriate type and values and just bodged a makeshift replacement on the board (the footprint was for a completely different fuse type). Finally when I decided to just replace the powersupply with a better brand and reclaim some of the components it was clear the supply had failed due to poor thermal conductivity on the mosfets (barely any paste and no thermal padding). Ever since I have become quite a bit more careful with supplies and such that plug in straight to mains.
Help!!!!! My AWC708C LITE does not communicate via network cable with the PC. I use LaserCad and all drivers are installed. I use a T568A network cable.

Thanks for very detailed video.. it helped me a lot
Thank you for making these videos even tho they are not the types of videos that will get the most views! You are the best!
Thanks Andras.
Also, I am currently on a national competition in Hungary and I learned most of the stuff from you.

You are quite welcome.

@@xConundrumx Being careful is always a good thing.

Funciona com bateria?
Não, o controlador usa uma fonte de alimentação de 24V.
