Nice work!

The quickest way to get a picture to the right size is Microsoft paint. Use resize and then choose pixels. Use either 800X600 or 1024X768. You only need to change the first box it will automatically change the other box. Then save the picture.

The picture below was 1000X1000 pixels already, but it will reduce any size photo down.

The nice thing here is it is on every version of Windows and works.

It's not grbl or BCL anymore now its a wiring problem on the adapter. I found the reset line broken loose. So I will have check it out for other broken connections. An adapter board would be a lot more reliable than this wired up adapter is!

I have grbl 1.1e on the Mini-Mega it runs and works virtually, which it did not do before with grbl1.1c.

I would really like to get this thing going. When it was running it was smoother than the Nano. I think this is due to larger buffers and more working memory. It was not faster, maybe .1%.

That is the story with this Mini-mega, it is contrary, Like a mule! LOL

Made a try today at running the Mini-Mega adapter. And of course it wants to act up. It will move in the Y axis but not X. It is not a problem with the steppers. They work fine. Not a driver problem either. I found the reset wire broken loose. So I will have to see if one of the others has gotten loose also!

Except for no X axis it did complete the shapes! One burned line! LOL

Heh, I just look to my left of my computer desk, i have mains powered uninsulated stuff sitting on my desk, a kWh plugged into snipped wires on an extension cord, a lithium battery with a bare pcb connected to it under a pile of wires and who knows what else dangerous.
20+ years of having your hands in the back of tv sets makes you a bit blaise to dangerous things.

You should be able to copy the gcode, as a *.nc file, to the card. example; "". I cannot remember if T2 uses the *.nc format to save its gcode. It most likely does. But you can only save the code directly in T2 with the full version.

All you need to do is copy the gcode from the window. Copy it into a text editor. Save it with that

Then the board should recognize it and allow you to run it!

The first time you burn any file I would do it from your computer. Set all the settings, like speed, intensity and such right. Then save the gcode onto the SD card if you think you want to use it again. The problem with this, on a laser, is that you would have to use the same material that you created that file with. If you change materials you will have to go through the setup and testing again and create a new file with the new settings.

The standalone would be great for repeat jobs. It is not so great if you are changing materials, sizes and stuff all the time. If you are creating new stuff all the time then the computer is what you will have to use. If you are engraving wooden nickels then the standalone feature is really good!

There is also an old term called "sneaker net" that is where you run everything from computer to computer using you r sneakers! In this case you save the file on the Laser SD card from the computer than walk it over to the Laser to burn. A big pain when trying to work up a new project. Great for cardio!

See wild.bill has tipped over the other side, real bad! Not a cat photo or a video, but a Cat etching. He has it real bad! Next he will be etching on real cats!

You are one of the moderators!!! If we have lost it, you are the one who let us.  :o

Unfortunately I am used to crazy people so you are not that far out to me. I am willing to participate until you people start posting cat photos and videos, then you have to go! LOL!

For repeat jobs, standalone with the LCD would work. I do not have a lot of repeat jobs.

I thought this might be good for Ralph as he was selling the belt anchors and some other parts. Sounds like he has that covered.

But having the board handle the print, or laser, rather than streaming the code from a computer, might be helpful for some. I think that kind of functionality would be great on these lasers. Once the code has been tested and corrected there is no reason to have a computer tied to the laser or 3D printer. And some of the boards Ralph has set BCL up to work with can accept LCD's and have a storage card. Like the RAMPS boards.

These are the kind of advances that people here have been headed for; Flexibility, advanced features and better firmware.

I will be interested to see your progress!

Thanks Richard for that information. I don't have a need for an LCD screen to control a 3D printer or a laser machine. I have a PC for each device already and I'm used to running BCL on each PC to control the device.

Yeah I chose an under $100 tablet rather than the $100 LCD from Printerbot. The LCD are usually about $30. I like the flexibility of the mounted tablet.

Generally the LCD is used just to run files stored on storage card like a SD Or Micro SD card. EDIT: you can enter settings. So you could take your favorite gcode files and leave them on the Lasers SD card. Then run them without the computer! This is an add on option for many 3D printers to run them standalone! The LCD and knob, sometimes buttons, allows you to select files.

Without that you have to use one file only on the card to run standalone or use your computer. Sometimes they will run the last file added, depends on the printer board. You should look into it for your replacement 3D printer. I could see where it would be very useful on a laser too!

You did not have the LCD on your FolgerTech? A handy addition for someone like you that has 20 projects going at anyone time!

install LCD Prusa i3

how to use LCD prusa i3

I chose the I3 because you are familiar with it. Looks like a whole lot of things can be set via LCD!

I feel lucky then. I had to replace a board on my printer. That was caused by tripping over the USB and ripping the USB connector off the board. Printrbot has moved away from the Micro B USB because breakage was way too common. They went to the B, full size, connector like you see on inkjet printers. I still have the broken board. It can probably be repaired.

Most servo's need 50Hz to operate. You can find ESC's that operate over 400Hz. You will find those for the small 250 size quadcopters motors.

I suspect we all have done something like that. Just don't like to admit it!!
