yes just make sure its v-slot . i ran 2040 on all mine but used t-slot for the 2020 would go .
here is a pic of mine so far been making a few custom parts . that i have been sharing on thingiverse

 

Wow, i like your Y with integrated 90° brackets Btw, aluminium plates will be better, right?

 

of course . but if all your doing is laser its way over kill

 

Thanks too much for your support!

 

Greetings. New member and first post.


I have been following along for the past few weeks on this build and I am preparing to purchase the items needed to build my own. I intend to stay on the beaten path using the xPRO V3 and the 6w Opt Laser head with the Z axis used by WildBill.

In an early post Peter provided a part no. and link for the 6w Opt Laser unit. The part no. shown was PLH3D-6W which according to its manual requires 12V input power. However, the link arrives at the more costly PLH3D-6W-XF, which works with 12-24V. The Arco bundle power supply option menu only lists a 24V power supply and the parts list shows a 24V power supply being used, which would not be compatible with the PLH3D-6W. The xPRO V3 seems to work with 12-24V input power, so it can cover either input voltage.

I am hoping for some clarification on if the -XF laser head is the one required or if the less expensive 12V only PLH3D-6W, with a 12V power supply, can or should be used. Are there advantages and disadvantages of a 12V vs 24V system, other than lower voltages being more susceptible to voltage drops? I have a 12V PS so going 12V would avoid a small cost, but I am willing to spend the extra to get a better functioning tool.

Thanks for the helpful forum.

 

Thank you for the reply Giarc. It is an interesting idea using a dedicated 12v PS for the laser. It leaves open the alternative of using the 12v only laser head with a higher voltage motion control system in the future.

Since I am new to all of this I was concerned that steppers might not perform as well with a 12V source. I would think that lower current requirements at 24v might be a thermal advantage, but moving a laser head around doesn't seem like an especially demanding load.

 

How would I convert this into a pen plotter?

 

i would thank u could swap out the laser for a 12v solenoid to move the pen up and down when writing. pretty much how a vinyl cutter works . btw most vinyl cutters come with at option . and in the long run for the size would be cheaper . i have a us cutter 36" run my about $350 and came with a lot of vinyl.

 

hmm... yeah solenoid... that sounds like it's what I want. I see a few for $9 on ebay, so maybe I'll go that route. Just gotta figure out where to connect the two wires to the cncshield. Maybe the same as where the laser is attached? (z limit pins)?

 

I'm needing help getting my laser to turn on
Currently using:
PLH3D-6W(opt laser)
xPro v3 driver board (openbuilds)
12-24v power supply (openbuilds)
all of my connections are correct and am using TTL/PWM
Laserweb4

The fan on the laser unit runs, but diode will not. I am currently using the settings suggested on the build page
What should iI check for?
What settings should I try to mess with?
Should I try and revert to an older version of laserweb?
-thanks in advance

 

Hi everyone, building an acro and i should be getting the step motors tomorrow, ordering in portions because i though i had the 20x40’s to be 20x20 which i had to build a delta printer, also i cant find my extra step motors so i had to order from openbuilds, but my question is about the software im going to use a nano cnc shield and where i will get the software for the board and cnc?

 

If it's a clone nano cnc shield (Arduino based), you probably need a version of GRBL older than v1.1. It's difficult to say, though, without knowing which board you have.

 

Thank you for your answer, I have UNO r3 and is a clone for sure but at least doesn't say "made in Italy' but "design in Italy" I will start building the CNC today so lets see what happens..

 

The shield will define which GRBL you need. If it's the clone v3.00 or older, use one of the GRBL 0.9 variants. If by chance it's v3.10, you can use GRBL 1.1. Good luck - I'm having lots of fun with mine.

 

I just found out I need a laser driver board and the only ones I found out are from eBay and they will be shipping from China which will take a few weeks, anything here in the states?

 

What laser are you looking to use? I use that same UNO shield with a TTL laser and only used what came with the laser.

The other thing is you can use the current GRBL with the old boards, you just need to swap spindle and Z limit pins.

 

I have a 445 nm 1.6 w laser and doesn't have the driver board, came with a power supply.

 

OK - most 1.6W laser's are two wire so you need a FET to drive it.

 

You might check DTR's Laser Shop: Laser Drivers - DTR's Laser Shop

He's also got some links at the bottom of that page for some other sources.

 

I ordered the board from banggoods and will take a while to get here, I finished my build and besides waiting for the board I was trying to find software to control the CNC, just to see if they move and I never though would be that difficulty, I built 2 Prusa's and 1 Delta 3D printer before and is a ton of info about software but not as much for CNC. I'm not paying for a CNC controller software and laserweb didn't work on my computer -I built the CNC at work- and the reason could be because they basically block everything, the GRPL Panel I have no idea how to start that program and I couldn't find any info on that so I'm going to surf reprap forums to look for more info.

 

Thanks, Im going to try the support community and reading the docs.

PS thats what I though I need the port 8000 open and barracuda (firewall) is blocking

 

I think that the ACRO system is not suitable as CNC router/engraver. Light engraving such as name plates would be OK but don't try CNC routing as if you're using a larger heavier machine. I'm afraid of buying a laser kit because I don't want to burn my house down or go blind. Any suggestions?

 

As for going blind, invest in some high quality laser goggles, or build a laser shield out of suitable material (like I did here: https://openbuilds.com/projectresources/laser-shield-box-for-spindle-adapter.285/ )

 

I want to buy three C-Beam® Linear Actuator Bundles but they are made for NEMA 23 motors, not NEMA 17 motors. I already have CNC xPro board and 24VDC PSU. I'm not sure if CNC xPro board can drive NEMA 23 motors.
