Custom Size Frames / Re: Little CNC mill
« on: July 12, 2017, 11:50:56 AM »
0.1mm, your talking 4 thousandths of an inch. Pretty darn close considering you're dealing with Aluminum extrusions. My mill is CNCed and I can get it within 2 to 4 ten thousandths of square. I think you are doing pretty well in the square.

I think you will find the table is out at least that much. If you have a friend with a mill you could lightly fly cut the table and spindle mounts and get closer. You might get closer by measuring the rails and then matching them to get the best fit, but that is a lot of work.

Most likely you can get better by milling then measuring then adjusting.

Laser Safety / Re: Red glasses

I have the red and they definitely cut more light than the green. I have trouble seeing the beam. I more have to watch the burn. Th beam is near invisible.

The original fourth axis threads had to do with more efficient cutting. As each cut is completed the laser is a bit out of focus due to the depth of cut. With a low power laser this causes increasing number of passes as the cut gets deeper. The idea was to lower the laser module at each pass to maintain proper focus. Ha should reduce the number of passes to finish a cutting project. Of course it is not just that easy as ash removal, smoke dispersion and probably several other things are working against you.

Also needed if anyone wants to attempt 3D laser work such a bas relief projects. Or they wish to engrave an item that is not flat.

Engraving a round item such as a pen barrel does not need a fourth axis unless it is more complicated work like a 3D carving.

Very nice!

Repositioning the board for better reception might help too. Stand it or turn it 90 degrees and see what you get. RDP into the desktop and use the WiFi meter to see if you are getting a better signal!

Check the RasPi power saver settings using the desktop. You can use RDP to run the desktop over the network on your main system. It might be turning off the USB ports which disconnects you!, then it will not reconnect until a power cycle lets it read the USB ports again! This can happen with Ethernet or WiFi as the USB chipset rolls both into one chip, the LAN9514 on B+, 2B and 3B. On the originals before B+ it was a LAN 9512.

Ok now wait a minute I have this wrong, you said it is still printing. I have to think about this a minute! Hmm! I know the earlier ones could NOT shut off individual ports, for power savings. I do not think the B+ could either. Not sure about the 2B or 3B!

What is the "lease time" in your router for WiFi or specifically your Raspberry Pi?

Looks like the files stay in the queue on octopi when I transfer them to the local (Pi's sd card). I should be able to just reprint them. I am printing a purple Benchy for my daughter now (I love being able to sit inside and be able to watch my print through the camera) and will keep the file in "Files" list and print a few other things, then go back to it.

So far, I am liking OctoPi. Only bad thing is that my garage sometimes gets spotty wifi, so I lose it on my computer. I have yet to move my router to cover my house better.

Does anybody know how to import a profile in for Cura on the Pi? I would love to just transfer a small STL and see how long it takes to slice it (such as a filament clip)
Storing the files on the Pi means you can print them from any computer with access to the web page. Make sure you have the printer behind the firewall! And passworded!

That's what I did when using Octopi. I transferred to the RasPi and printed. I was able to save to the card through Octopi. Then start them to print. That would be handy if you had things you repeated prints on.

Hey I forgot about it too! Until I tried to open CURA on my main computer. It only wanted to save to a card!

Very short cables to the Tablet. They stay out of the way! I only lose connection if the power goes out as they are both (Tablet & Printer) power by the same PSU! Turned off all power saving features of course!

If you are connected USB to your printer, CURA will bring up one of two interfaces to operate your printer. Either the basic interface or the Pronterface UI. You set this in preferences (under file on win). I use PronterfaceUI.

If I remember correctly the Basic interface just shows that you are connected and has a print button. Pronterface allows you to preheat the bed and the Hotend. It shows a graph of both bed and hotend temps continuously.

But you have to be connected to the printer by USB or it just tries to send it to a storage device a SD card.

In Preferences you can also set your cost for filament and the roll weight to get a estimate of project cost!

If you are trying to send to the printer over that wireless setup, you are going to have to look up a way, to make it look like a USB connection. It wants a serial connection on a COM port.

Repetirer may be a better choice for what I think you are trying!

STL / Re: better belt tensioner

Looks good ,,,, but no 3D printer,,, How could you!!!! LOL!

Mine came supplied with an 8G sandisk ultra (normal size though not micro) and you can select which file on the touch LCD, it kinda sucks though as it only shows the first 10 or so characters, also the SD had cura on it in a chinese named folder that displays .. non unicode garbage.

it will not print anything that is not in the root folder though.
Yeah those control panels have some drawbacks. That Cura folder is probably meant to be installed on your PC. They figure that it has the room, so why not! I have had several devices that did that. My Taranis R/C radio had software on it when it came and I believe my Yuneec Q500 also had software on the MicroSD card.

My guess is it is CURA with the proper settings installed for your printer!

Mine will not print anything that is not in the root either, very common!

Your printer still broke down?
