Yes. I would love a movable table... For now, as I am mostly cutting thin polystyrene and cardboard, I rarely need to move the table height. I would like to start engraving timber, though.

 

You can get the same power for $99. You just need to add a heatsink and fan. That's an expensive 5.6W diode.

 

DXF is AutoCad interchange format - many apps can read it.

Inkscape and Adobe Illustrator are two that spring to mind.

 

Your laser is ATTACHED to your Z axis mount, but you control it through PWM, if you have a PWM capable laser module. If you connect your laser to your Z+ pin on your controller, it's likely something will break.

If you are running the GRBL CNC shield, best go back to the maker and ask specific connection info - I'm not familiar with that board.

 

So this diagram is wrong???

 

That diagram shows the laser attached to the PWM control pins.

If you have a diagram of the connection, why did you ask the question?

I’m confused about what you want.

Edit: well that diagram certainly does show the laser connected to the Z- endstop pin... are you running modified GRBL code?



According to Protoneer, the designer and maker of genuine CNC Shields, you connect a laser to the SpnEn pins: Laser TTL - Protoneer Product Forum

 

Further confusion...

Protoneer say to use SpnEn, openbuilds say to use Z-

GRBL Shield help.

I’ll send an email to Bertus (the designer of the CNC shield) and get a definitive answer. Although I’m not sure Openbuilds aren’t using Chinese cloned parts, so it may be more appropriate to make them do the heavy lifting for saving $10...

 

So is it connect to SpnEn or Z-

And I also confuse that this Laser Module can direct connect to SpnEn or Z- without TTL modulation?

 

GRBL version 0.9j

 

So i just plug my laser module to Z+ due to my CNCShield is V3.00 version?

 

If what you have is the same as that picture, you’re missing a constant-current laser driver, heatsink, fan, power source.

All you have there is a diode in a holder, no control electronics, no way of managing ttl/pwm.

You cannot just add that to a CNC controller and expect it to work.

 

So any TTL Module suggestion? Something cheap and functional?

 

I was wrong. Your module does contain a driver, but doesn’t support ttl.

Plus, at 200mw, I’m not sure what you expect to do with it - it will barely mark paper.

It’s a laser pointer, effectively

If you want a usable laser, x-wossee has a great TRUE 4.5W unit for US$99 that can actually cut and mark stuff. https://www.ebay.com/itm/4-5W-Engraving-Laser-Head-with-thermal-protection-PWM-NUBM08-455nm-445nm/152781917480

That only needs a 20x20 heatsink and fan and will plug straight into a 12v power supply and your PWM pin and can actually do decent engraving and cutting of things like 3mm ply/mdf, 1-3mm black acrylic, balsa, fabric, cardboard, and can even engrave coated metal plates.

Sorry for my previous response - it was late and I didn’t notice the power of that diode module and just shot from the hip.

What do you want to use a laser for? 200mw is 1/5 of a watt - and even with a watt you would be pushing it to mark paper.

 

Hello from Canary Islands

Sorry I'm so "rookie" in this world but here is my questions...
I just bought the Acro 1510 system and I still have not decided the laser to buy. I would like to cut plywood (maximum 22mm in several passes) engrave wood, iron, stainless steel and iron.
Another question: can I add a rotary shaft to engrave tubes? Are there 5-axis controllers that can be adapted to also give movement to the Z axis?

Thanks in advance

 

I've accumulated what seems like at least 100 hours of operation on my acro laser with xPro board. This morning, I turned the unit on and the drivers did not lock in place! the voltage to the board is good, the laser can be turned on and off as well as other commands can be issued($$,$x, etc) but the move commands don't do anything! What gives!? How do I go about troubleshooting something like this?

 

hi, is there any open source for z axis control mount?? ex j-tech z staging

 

So does that mean a proper board bought from Protoneer should be on the SpnEn pins? Something to try I suppose since on the Z+ pins the laser is always on. It is confusing since Arduino CNC Shield – 100% GRBL Compatable shows that the d11 pin is the Z endstop.

 

Hi, just got my laser ACRO going, can someone tell why my engravings are coming out mirrored or backwards? Thanks for your time and help.

 

Could it be my X axes wired backward? Thx

 

Got it fixed.

 

Hey is there a video out there to help me set this up, i just cant seem to get things right. when i try and do a homing cycle it will crash into my limit switch and just keep going, but when i jog into the limit switch it will stop and the alarm activates like it should.
Thanks for the help.

 

So no one can help,

 

I have the ACRO system in my cart, I have an "old 3d printer" which I am going to re purpose the 24v steppers and power supply. Does the Acro Kit ship with the timing belts and pulleys needed or should I add the mentioned parts to my cart. Also when will the CNC xPRO V4 Controller Stepper Driver be ready for shipping to customers?

 

It comes with the belts and pulleys.

 

Thank you very much! I am looking forward to building this laser engraver!
