Gene,

I only print from SD. I'll try to downgrade my Arduino IDE and see how that goes but I'm not sure I will feel the need to right now since I'm up and running well. Is there a history of major updates to the firmware somewhere linkable?

Thanks,

Hi, all. I'm trying to figure out what exactly would cause the printer to stop mid-print. Last year I attempted to update to firmware version dated 20170414 from firmware version dated 090816 and I had this incessant problem where the printer would completely forget that it was printing something. I...

I'm experiencing a very annoying issue that seems to crop up randomly. I cannot correlate it with anything in particular. My prints will randomly have pitting evident on the exterior surface (photo attached). I believe this is due to inconsistent extrusion. I've been using both PLA and ABS on this p...

Thanks for the input. I am using a handheld gun-style thermometer to read the temperatures off of my bed and I've never seen it to be accurate. I suppose this could be caused by trying to read through the clear glass, but if the temperature I'm seeing off of the thermometer is accurate I then wonder...

My thermistors read 27C when at room temperature. It's currently 62F = 16.7C in my house... This has to be throwing off all of my temperatures that I'm printing at... Anyone have any information on how I go about calibrating this?

Thanks,

If you're not concerned about containing a large percentage of particulate coming off of your printer, you can opt for my low cost enclosure solution. The curtain enclosure: image.jpeg The curtains each measure 28" x 15.5" and are cut from pleather that I had hanging around the house. I wo...

I am here to report success! I ran into the issue again when I removed the Bowden tube to calibrate my extruder. I noted that I couldn't reinsert the bowden tube as far as it should be (since I now have the insertion depth marked with laptop tape on the Bowden tube). Sure enough, after 5 or 10 hours...

You need to save your 3D View window before going to Layer View. Thanks for the reply. I was doing this. I also went so far as to make an stl with multiple shells. It worked with other files but still wasn't working for this one. It wasn't until I decided to change my pre-defined print settings for...

Thumbs up to this. I had the same problem at my hot end yesterday. DEF in the middle of a five hour print. Removed the thermistor clamp screw, lined it with kapton, laid the thermistor back down and replaced the screw. Temp went from reading about 19C to 27C (19C must be the value it reads when one ...

I've used the "insert" function to make a 15-up arrangement of some small parts. When I slice, only one slices. The kicker is that the one isn't even the original added object... Any ideas what the heck is going on?

Thanks,

-Matt

Thanks for the details, I'll report what I find when I've cleaned it, myself.

I have 53.5 hours of printing on my machine. I always run at 235 on the hot end while printing ABS. I tried inserting the Bowden tube while at 235 on the hot end, but it didn't seem to extrude any more fluid out - that made me think that the purple inside is just solid and not remelting. I'm about r...

So, I did a little more digging. As a note, I have ONLY used ABS on this printer. This occurred after I started using a less expensive ABS filament from JET. These are the filaments I used, in the order that I introduced them to the printer: 1) $29/kg White ABS from MatterHackers 2) $42/kg Clear ABS...

I think YouTube compressed this video too much, but what I was trying to take a video of was the motor continuing to spin, but the filament only feeding during approximately half the rotation. When I first noticed this happening, the knurl on the motor was filthy with plastic shreddings, so I though...

Bill, My v3 has done the little "stutter" since I first set it up. Some may argue that it may not be optimally aligned, but I have no problems with printing. I've made full bed grid prints in order to map the temperature of cold and hot spots on my bed and I'm able to use the entire bed wi...

I made some drapes with pleather and green painter's tape (just so the adhesive won't leave a trace). Works pretty well to help the ambient temperature remain stable. I think I used 15" by 28" panels. Just long enough to tape at the top and bottom. I also used painter's tape to insulate th...

Thanks for the recommendation. Once I get a print I'm going to start looking to refine things - changing slicers, different print surfaces, increased speeds, etc etc. I actually slowed down the speed to 75% of the standard values in Matter Control and it's looking all warbly. If I can just get a suc...

I'm printing ABS and I started with the standard ABS settings in matter control. By default it doesn't turn the three-fan-array on for ABS. It only runs the one PCBA fan. UPDATE!! Matter control turns the fans on by default with ABS but it isn't obvious!! It doesn't have them on when it prints the ...

Yes, I believe that is correct. I love the knowledge and collaboration here!

Are you sure about that? When I was missing a print head thermistor and I had finished the rest of the build I plugged in my printer with no print head attached and turned it on to see if everything else was working properly and the bed heat would read out but the head heat wouldn't display.

Thanks for the detail, Xenocrates. That's very helpful for a mind like mine that needs to know "the why". I started thinking more particularly about the "killed" scenario. What prevents the printer from cutting power in a circumstance where the bed reaches a thermal equilibrium a...

Thanks for the explanation on the "killed" message. How do you clear the Rambo memory? I wanted to hear someone elaborate more on when and why to probe. It would seem to me that you'd want your bed and head to be in the heated state so that any expansion is compensated for, but I could be ...

I'm printing ABS and I started with the standard ABS settings in matter control. By default it doesn't turn the three-fan-array on for ABS. It only runs the one PCBA fan. That's great info about the timeout. It seems strange to me that the head thermistor would also def and it would totally cut out ...

Two posts, one day! Sounds like an internet meme.. So... My third attempt at a print larger than a 1cm ball. I'm printing ABS. Because, why not throw yourself into the deep end when you build your first printer, right? I made a post this morning about def thermistors and other strange issues. Here's...

So, yesterday I had a problem while doing a test print wear a half hour into the print both thermistors went to DEF. The print kept going, unfortunately, even though there was no heat to the hot end. Upon cycling the power the thermistors immediately came back. So I went along to print another sampl...
