And how can i install my machine setting on grbl

 

Is it will differ if i use arduino mega ?

 

nop just select the proper card in the arduino software, use the grbl panel to enter all the machine parameters gerritv/Grbl-Panel

 

sorry sir but the last question , what is grbl panel ? and thanks a lot for your help .

 

And how to use it

 

You can also use LaserWeb to configure GRBL: LaserWeb/LaserWeb4

 

Alot of thank

 

The problem is that I'm powering the xpro with an atx power supply so I I'm not sure how wiring that could work... I've already wasted over $800 on this thing so I should have just bought a pre-built laser engraver =/

 

So I just put together my ACRO 40x20.

I have a whole extra 4" double extruded aluminum beam, that I don't know what to do with. It's not in the build video. It has a 9.5" piece of rubber slot strip in it. Does anyone know what that's for?

I also have a fair amount of screws and a little bag of angle brackets left.

 

Hello, I've assembled my ACRO and it is awesome, I have the laser powered up with a power supply and my PWM PIN attached to the cancelled shield. I have not been able to get grbl to turn on the laser. I've used the commands to turn the laser on m3, just to try. I have been looking at all the wiring diagrams but I think im missing something.

Does anyone run a 3.5w 3 wire chinese diode that can help me hook this up properly? I am using an Arduino uno with a v3 cnc shield in laser mode. And help would be appreciated.

 

Buy this https://www.amazon.com/gp/product/B00CHTLAIS/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1 then ill help how to wire it up that is your missing link

 

@pedrofernandez thanks, I will get my hands on one and let you know.

 

Ok got the mosfet at a local mom and pop, little more than I wanted to pay, but I'm motivated to get it done today

 

I've seen a bunch of projects posted on openbuilds where people are routing out the brackets for the ACRO system, but I can't find where/if the DXF files are provided anywhere. I would like to build an ACRO, but I thought since I already have a CNC I could save some money cutting the brackets myself and then just buy the hardware from openbuilds. Am I missing something? Thanks!

 

your power supply is the same for the machine and the module?

 

It can be... I have both available.

I tried opening it in F360, Inkscape and Aspire, and it didn't work in any of them. Any idea what program I can use to get the DXF file to play nice? Thanks!

 

both are 12v or 24 for the machine and 12 for the module

try sketchup

 

Hey sir i have aproblem in this image

The pins out are for three motors and my x plane has 2 motora not one how can i do that

 

I have a question. How fast does that carriage move. Example , can it move 1000mm per sec or something else ???

 

recommended settings:

$0=10 (step pulse, usec)
$1=255 (step idle delay, msec)
$2=0 (step port invert mask:00000000)
$3=6 (dir port invert mask:00000000)
$4=1 (step enable invert, bool)(Board V1, V2, V3 Matte = $4=0 - Glossy board V3 = $4=1)
$5=0 (limit pins invert, bool)
$6=0 (probe pin invert, bool)
$10=0 (status report mask:00000010)
$11=0.020 (junction deviation, mm)
$12=0.002 (arc tolerance, mm)
$13=0 (report inches, bool)
$20=0 (soft limits, bool)
$21=0 (hard limits, bool)
$22=0 (homing cycle, bool)
$23=1 (homing dir invert mask:00000000)
$24=25.000 (homing feed, mm/min)
$25=500.000 (homing seek, mm/min)
$26=250 (homing debounce, msec)
$27=1.000 (homing pull-off, mm)
$30=1000 ($30 - Max spindle speed, RPM)
$31=0 ($31 - Min spindle speed, RPM)
$32=1 (Laser mode, boolean)
$100=114.290 (x, step/mm - 1/16 step - Set this according to your boards step setting)
$101=114.290 (y, step/mm - 1/16 step - Set this according to your boards step setting)
$102=114.290 (z, step/mm - 1/16 step - Set this according to your boards step setting)
$110=10000.000 (x max rate, mm/min)
$111=10000.000 (y max rate, mm/min)
$112=10000.000 (z max rate, mm/min)
$120=2000.000 (x accel, mm/sec^2)
$121=2000.000 (y accel, mm/sec^2)
$122=2000.000 (z accel, mm/sec^2)
$130=1000.000 (x max travel, mm - Set this to your machine safe cut area)
$131=1000.000 (y max travel, mm - Set this to your machine safe cut area)
$132=1000.000 (z max travel, mm -Set this to your machine safe cut area)

 

while those settings look great. I am wondering if someone is actually able to run the acro safely at 1000mm per sec.

 

So you are asking if it will safely run 6 times the recommended max rate, correct?

 

I was just asking what the normal max speed was. So I guess its around 200. That answers my question

 

hello - can you post a diagram or simple explanation to how you have the bulbs set up? I'd like to do this too.

 

So I've read 1000 different safety manuals and they all agree that you shouldn't look at the dot your engraver makes, even with safety goggles on. I'm trying to focus my laser diode and can't figure out how to do that, or monitor the engraving - except by setting up a video feed (which I'm looking into.)

Is it true that you can't look at a laser's dot even with googles?

I have a pair of $60 OD6 goggles. thinking about returning them in exchange for a raspberry Pi video feed.
