Centroid Community CNC Support Forum

Boostedss,

Hello again. What have you done so far?

Are you using the original PSU for your laser or are you using a new PSU?

Try mechanical switches and an E-Stop for the H-Series.

I will try to make up a set up for your PSU soon after you reply letting me know what has been done and what type of PSU you are using (new or older/original).

# Update on Building the Simple Schematic

Not so simple. My software keeps halting at removing and adding in specified parts (basically just lines with signification of what goes where).

I will keep trying. I am going to the mfg. of the source that I use for altering the DWG files from Centroid.

Seth

P.S. I will update you soon. Please, when you have time, let me just know what you have done thus far. This will get me on board with what I need to do to help.

Okay. THIS IS NOT 100% CORRECT as I do not know what is going on without a google photos album and set up of current wiring diagrams from you.

I figured this could get you going. I have not accounted for the inputs (end stops), fans, tanks, tubing pump(s), and/or air assistive technology.

The laser has two ends. One is GND (reference voltage) and the other end is PWR. PWR on the laser is attached to the PWR source on your Laser PSU. GND on the laser is attached to your laser negative source on the PSU. Reading this helpful article will help.

Remember to start a google photos account and give the link along with your CNC12 file for your current set up.

Oh and here is the current article: https://laser-welder.net/laser-welding/ ... ide-laser/

It is a short on laser usage, use cases, and it has a simple diagram in it during the first 15 minutes of reading.

The reason I typed, "THIS IS NOT 100% CORRECT," is because of this photo as I do not know anything about your current set up, the PSU being used, nor do I have photos of your process so far:

Again, this is a starter to get you more acquainted with the H-Series and PSU usage with your set up if you have started or not...
Please take this into consideration too:

1. Before powering your laser:
a. Do not get your laser PWR and GND attached yet.
b. Make sure the mechanics work first.
c. This basically means make sure the motors work with the set up, the end stops are in working order, and your E-Stop is attached and fully functional (and all within the CNC12 source available via Centroid).

2. And this goes with most electronics:
a. Make sure the 5v is actually 5v when plugged into the 115v supplies.
b. Make sure the 24v is actually 24v when plugged into the 115v supplies.

3. So, 115v will be your PSU(s) source from the house or shop to your laser PSU and board PSU.
a. I have three PSUs for my current set up.
b. I am not running my machine currently, i.e. as I have other endeavors right now.

So, within the CNC12 source from Centroid, make sure your motors do what they are told to do and make sure the end stops adhere to the stoppage and zeroing of your motors so they know where they are located. The E-Stop is extra precautionary and needs to be used to work with your AcornCNC kit.

Hopefully, this is some good advice and not to be taken lightly. Lasers are very powerful, as you know, and from what I can tell Centroid put in a good bit of work to make this Acorn low cost and a reasonable, viable option for machines. So, outside of kiss up and do well with safety, reply.

I will be able to help more. Put in your report.zip file for everyone to see what you have done and any and all photos in the google photos album and make it so it is not private.

If you need anything from me, ask away.

Boostedss...if you want me to make a complete schematic, okay. I will but it will be far off from now. Maybe in mid April or late April is when I can probably find time to configure things correctly for the entire build.

Hey silver so I got the laser working. But still have a lot of kinks to work out I posted a video on the Facebook group. I’m having issues with well I think it’s my mirror alignment

Posting the Facebook video, to keep everything together for future reference.

WARNING: Loud!

neat...good luck.

I know the mirror alignment is an issue with a lot of people. I will review my older paperwork on their manual. I will see if I have an electronic copy somewhere. I will report the findings soon, i.e. as the mirror are fickle with adjustments.

Just a heads up here:

1. Center the beam to each mirror.
2. So, if you have thermal paper with an adhesive backing, first place the thermal paper on the first mirror
3. Then, take off the thermal paper with adhesive backing and clean the mirror.

Next, rinse and repeat with each mirror, e.g. I know the alignment is done by adjusting the screws. If you move one screw and adjust another and so on, the mirror moves. Let me get the paperwork, i.e. as this will be more handy than more English jargon.

Seth

Boostedss,

Here:

There should be some alignment photos in the slew of pictures.

Seth

It seems the laser is not actually liking your arrangement. I see crosshair marks when the laser gantry is traversing instead of the laser pausing until next fire.

Seth

Wouldn’t let me upload video so had to take screen shots
