I just became the proud owner of a oneup and i'm looking for the old community port of marlin so I can add an LCD to it and have some code to play with.  Anyone have this saved somewhere?

  It's a SECRET!
Posted by: MisterAcoustic - 2019-03-20, 10:50 PM - Forum: General 3D Printing - Replies (2)

Hi All!

I just got an email where someone told me not to tell anyone about it until March 26th.

But I did find what they told me to be very interesting Smile.

I guess I can't say anything more, other than perhaps to note that I'm already making plans for them to take my money Smile.

I think quite a few people checking in here will be very interested as well. But... I guess you'll have to wait until the 26th!

Check back - I'll let the cat out of the bag absolutely as soon as possible.

You heard it here first!

  Fantastic Veritasium Video
Posted by: MisterAcoustic - 2019-03-12, 11:53 PM - Forum: General Discussion - No Replies

Hi All,

Just saw this, and had to log in and post about it. I'm a subscriber to the Veritasium youtube channel, and he just posted a video that reminded me how cool 3D printing can be.

I consider this a must see. Go forth and watch, you won't regret it:

Oh, and you will probably want this link when you're done with the video Smile

Enjoy All!

EDIT: Removed the annoying youtube redirect from the link.

  TV as Monitor, 4k/60Hz
Posted by: MisterAcoustic - 2019-02-08, 11:24 PM - Forum: General Discussion - Replies (1)

Hi All,

I splurged and bought a big 4k TV that I wanted to use as a monitor for my computer. I'm posting this to help others that might be in the same situation.

I bought a Vizio V505-G9, available at my local Costco, BestBuy, and I'm sure other places. I had to dig quite a bit, but I eventually convinced myself that it had full support for what I wanted to do.

In order to drive the TV from the computer, I needed a video card that supports 4k/60Hz at a reasonable price. I decided the option most likely to work was an Nvidia GeForce GT 1030. The important thing to know about this card is that there are two versions with the exact same name. Sometimes even the same price. But one works significantly better than the other. The distinguishing factor is the type of video ram used on the card. Some versions use DDR5, and others use DDR4 - though they are all called GT 1030. You have to look at the details. The DDR5 version scores much higher in many benchmarks, and people are questioning how the manufacturers can get away with the naming confusion. Check your specs, get DDR5.

I have a windows machine, but I elected to try to get it running on my linux (ubuntu MATE) box first. I installed the card, plugged in the cables, and had 4k immediately. However, the highest available frequency was 30Hz.

Then I begin a quest for 60Hz Smile.

I figure it's one of three things: The video card drivers, the HDMI cable, or settings on the TV.

For linux newbies like myself out there, I went off on some tangents before finding something easy. (tl;dr: don't do this first thing Smile ) I found a driver download on nvidia's site, which is a '.run' file. In order to try to run this, I had to chmod the file to allow it to be executable. Once I did that, I tried to execute it. A first error occured because I neglected to use 'sudo' to allow the file to run with administrator permissions. After fixing that, another error occurred, saying that I was still running an x-server. Great - I had very little idea what that meant, but I found some instructions on the internet. They were very confusing, not all applicable to my situation, and generally I thought they would break my machine beyond my ability to repair it.

I consulted a friend, and while I could have continued down that path, he mentioned a better way. In Ubuntu, there is a 'Software and Updates' utility (not to be confused with the ridiculously similar 'Software Updater', and slightly less similar 'Software Boutique'). This utility has a tab labeled 'Additional Drivers'. Opening the tab loaded up several driver options for my new video card, including a recent version of the (proprietary) nvidia drivers. I selected that driver, and it took care of the whole install process without a hitch.

Unfortunately, everything worked great. Except I was still stuck at 30Hz.

I had a nice, but older HDMI cable that I wasn't certain would handle the bandwidth required for 60Hz. Apparently there are cables rated at 10Gbps, or newer ones rated at 18Gbps. Some newer cables claim support for HDCP 2.2 (facilitating newer digital rights management schemes). Maybe I needed one of those.... but first I decided to check my TV settings for the twentieth time, to try to see if I'd missed something.

While I was looking at HDMI cable specs, I noticed that some cables claimed to support both 30 and 60 Hz 'at 16-bit color depth', and gave some numbers like 4:4:4, and 4:2:0. I haven't found out what those mean yet, but I did remember that the Input Settings on the TV had options for 'Full UHD Color' and 'Full Chroma 4:4:4'.

I thought, hmm, this looks vaguely similar... so, I changed the settings to turn on both of those things - and lo and behold, 50 and 60Hz options appeared in my display settings dialog.

I switched to the available 60Hz rate, and everything seems to be working!

I am very pleased with my new setup. Now I have to choose a window manager of some sort for linux to get things set up as 4 HD monitors on the same screen. And I have to see if I can get an HDMI switch and hook up my windows box as well.

I'll update here if anything interesting happens. Good luck to anyone out there trying to do something similar.

Stan

Edit: Oops, I totally forgot to mention that I was able to find the DDR5 version of the GT 1030 for $53 at my local Microcenter. They had several open box ones at a reduced price. They are usually in the neighborhood of $80.

  Arduino code download
Posted by: aistech - 2019-02-02, 01:46 PM - Forum: Q3DPrinter (formerly QU-BD) Specific Discussion - Replies (4)

I have had my ThreeUp for a couple of years now and done some upgrades to make it a pretty decent printer.  My big issue now is that I have lost my backup of the arduino code.  Does anyone know where I can download this for the ThreeUp with dual z-drive?

Thank you.

After nearly a year of delays and lack of communication, my Kudo3D Bean is scheduled to be delivered tomorrow.

We'll see how it turns out.

Hi All,

I tried to set the forums up so that a user's first post has to be approved by an administrator (usually me).

After I did this, I realized it didn't always work. In fact, I thought it was broken entirely, so I fell out of the habit of checking for posts that need to be approved. Today I looked, and I found a post from October that was never approved.

So, I apologize for missing that. I will either turn off that mechanism, or do a better job of tracking posts in the future.

  Looking for Setup Instructions - OneUp/TwoUp
Posted by: CyberMars - 2018-12-18, 06:42 PM - Forum: Q3DPrinter (formerly QU-BD) Specific Discussion - Replies (17)

I've decided I should print a better printer, but in order to do so I need to get my OneUp printer that I've had partially assembled in storage for a long time put together. However I can't find the assembly/setup instructions anywhere. Anyone by chance have those in digital form they can send or physical form they can photograph and send? I'd appreciate it.

  twoup firmware update
Posted by: xwarx7racer - 2018-11-10, 05:46 PM - Forum: 3D Printing Help - No Replies

I have the 'red' board that has been working ok, but would like to update the firmware to the latest that Marlin has. I haven't really seen much that shows me how to perform the update. I've loaded the IDE and have the zip file already for Arduino, but unsure of what to do on the board itself. Do I just set the bootloader jumper and ???

Thanks for looking!
