BenCutLaser / Re: Eleksmaker Mana SE PWM How
« on: Today at 12:16:53 AM »
yes the mana se board is the newest eleksmaker board on the market.

watch this video for details on saving a dxf.  I fast forwarded it to the exact part that discusses settings.  I dont use BenCut Laser but I do us T2 and these are the settings that work for me.

only thing I can think of is your power supply may have died.  Do you have any other 12 volt power supplies with a barrel jack you could try?

Also... this may be a dumb question but did you try pressing the little white button that says power on the new board?

that is the new board.  It doesnt need a conversion.  it was built to use pwm.

did you flash the board with firmware 1.1e?

Are you sure the motor plug is wired the same as your laser?  + to + and - to -?

Another option is to join a hackerspace/Maker group.

As for T2, it is a good program. And yes "How To" videos would be nice, nottingham82 has made a few. A problem that many groups like this forum have is posters assuming that another knows what is being discussed; connected to that is often arrogance or a "if you have to ask you are over your head" type attitude towards those who express that they do not understand. Techinical groups/discussions tend to forget that everyone reading the post does not understand. I post pictures as I that is how I best understand what is going on. As for your images,  load the image, select settings, select center start, then set your speed, resolution etc.  After the image is engraved, close the control window then select the outline function and outline the image - since you have start at center, the outline will outline to the engraved image.

As for an airpump, what are you expecting? Some people just use 12 pc fans. The air assist is mainly to blow the smoke, as the smoke can prevent the laser from engraving. Absent a high volume focused air, I dont think there is much ash to that could be blown away to make a difference. Also unless the air is focused and the flow is on a 90degree path to the laser, the gains from blowing other than smoke are zero or negligible. On a CO2 laser the airflow blows straight down the path of the laser, this means that no mater the cut the air is always 90* to the cut and can blow out ash. If the air is not 90* to the laser, then even if the air is focused it may only be blowing directly into the path of the cut a 1/4 of the time. 

For reference as to whether air assist is needed, I cut 3mm ply with 6 - 8 passes feed rate about 425 (same number or passes needed with air assist), I etch mirrors - front and back, I etch glass, I can cut dark shades of acrylic, all of this without air assist.

As for fumes, you will have that problem with a 40w also. It may be worse with a 40w as you would likely cut materials that can not be cut by a mw diode laser, so either way you need an exhaust system or use the laser outside.

Last of all, what are you trying to do with images you have?
 

Thanks for the + laser_cutter.  I like to do video explanations because I am a visual learner.  Text just doesnt help me most of the time.  I also want to make more videos on diode lasers.  My goal right now is one video a week.  I have a bunch filmed but need to edit.  I do need suggestions for what people want to see and what will help the most for both experienced users and guys that just got a kit.  I am going to redo my I downloaded t2 now what video and want to do one for elekscam, laserweb, and bencutlaser. I also want to do a troubleshooting video.  I guess I should also do some mod videos on rotary engravers, home switches, air assist, and such.  It looks like a I should also do a "where did my start point go" video and "how to use sketch plus to do a cut + engrave".  I would appreciate other suggestions on things that will help people.  I have a few weeks off starting next weekend and want to get some videos out.  Right now its been crazy since I am finishing my bachelors degree and working full time.

additionally you could do a fill and convert the thing to an image.  BCL now allows engraving so a picture (png jpg bmp) would probably work.

well you need a hatch fill.  If you made the dxf with inkscape you can do it with the eggbot plug in.

T2 Software Updates / Re: Is there a description for T2 firmware options?
« on: October 22, 2017, 10:33:32 AM »
alot of those special firmwares were for a specific user for a specific machine.  He publishes all of them so that if another user wants to use that setup he can  just tell them what firmware to download.  Most users just need the standard 1.1e.

T2 Software Updates / Re: Start from Center issues.
« on: October 21, 2017, 08:58:18 PM »
so i just looked at that.  It appears sketch filled uses the center of the entire sketch.  Sketch normal uses the center of what is drawn.  So if you use a 300 x 400 sketch the center for sketch filled will be at 150 x 200 no matter what you draw.  If you use regular sketch the center will be the center of your drawing no matter what the dimensions of the sketch are.  Sketch hatch does it the same way sketch does.    sketch plus does center start how sketch filled does.  Im not sure if there was a reason for this or not.

Personally I never use the default sizes in sketch.  I always make my sketch the size of my work piece.  So if I have a 100 x 100 coaster.  I use a 100 x 100 sketch.  That way my sketch matches what I will see exactly.  You can use sketch filled sketch hatch sketch plus or whatever and the center will always be the center.

Air compressors are quite noisy.

T2 Engraving / Re: T2Laser installation issue
« on: October 21, 2017, 02:18:22 PM »
It happens because Zax cant afford to have the software certified by microsoft.  When this happened to me there was a button on the lower left of the warning that let me override.  I am running windows 10.  I dont have windows 7 so I'm not sure how to bypass on that.

Trouble Shooting / Re: Laser Module Stopped Responding to PWM
« on: October 21, 2017, 01:58:06 PM »
Haven't seen anyone successfully fix or replace a laser driver.  Banggood has notoriously bad customer service and you may have to file a dispute with your payment service to force their hand. That being said they are supposed to replace the laser if it's that new. I would buy a replacement laser while I fight with them otherwise you may be waiting a few months to play with your new toy.

Sketch plus is a t2 setting. You won't find it on Google. Check the t2 help drop down

Yeah to get the black to show I think I used the paint thinner first to clean up the area. Then painted it.
