Welcome to the SeeMeCNC Community

Thanks for the link, teoman! I looked closer at the failed connection and it looks like the wire heated up and the wire insulation melted first. This was extra bad because the wires exit the RAMBo upward in the Rostock. So the melted insulation dripped down into the screw terminal, probably making t...

While adding a copper heat spreader, the heat bed stopped heating. While probing the RAMBo to check the bed voltage, I noticed that the insulation melted on the wire leading to Pin 9 (one of the Heat Bed leads.) There was also less than 12V (between 11.3 and 11.5) between the two terminals, though t...

Thanks ZakRabbit! The cheap IR thermometer is reporting temperature variations across the print surface ranging from 5C above the target temperature to 20C below it. Interestingly, the variations aren't strictly on a simple pattern like distance from center. (For example, right above the eyebrows on...

I really love the innovation! I'm just wondering why not go with E3D's Cyclops? Thanks! I think I bought the E3D V6's last year before the Cyclops/Chimera were for sale and the V6's are already here. Were I starting from scratch, I'd buy a Chimera, to permit printing materials at different temperat...

Designing a dual tool platform was reasonably straightforward if you can also print a new effector plate. (With all the important dimensions stolen from the SeeMeCNC STL files.) This one is intended for the Trick Laser arm attachment, where I can screw the threaded rod through the blocks, then screw...

The first attempt is printed and ready to install. There were a few minor design changes from the image above. The second EZstruder is shown in place.

Is there something else I can do to keep this extruder cooler? I grabbed 40mm heatsinks from RobotDigg , 40mm PC fans, and 60mm screws from McMaster Carr. They cool down stepper motors dramatically. (At least to my less-burned fingers!) I need to take before-and-after heat readings on the extruder ...

@gchristopher: my very first two prints (PEEK and layer fan shrouds) were essentially successful, and both were printed in ABS. I don't remember what temps I had set back then (January timeframe), but I suspect they were the defaults from the print profiles I loaded in the assembly manual. 180C see...

You said you switched from PLA to ABS? 180C extruder temp seems way too low, I thought the standard print profile for ABS called for 235-238C?

I started out printing primarily with Black ABS from MatterHackers with my stock hotend and got pretty nice results.

Assuming it's just he PSU, I was in a similar position and I was able to replace the stock PSU with a larger one (1300W EVGA, that doesn't drop below 12V under load) and that resulted in a 2x speedup in getting to 90C. It also let me get the bed to much higher temps, since 90C was about as high as i...

Thanks! The motor ends are actually spaced close-ish so a pair of attached cheap 40mm water cooling blocks will have a very short distance between them. I don't have a good way to bracket the cooling blocks on, but people suggested thermal epoxy, so I'll be trying that. The eventual dream is to have...

Others have posted perfectly good designs, but sometimes trying to come up with your own idea is the fun part. So, here's the concept for a dual extruder setup. I'm trying to arrange two EZStruders so that the filament comes down through the center hole. The EZStruder positions are offset so that bo...

All the cool kids have PEI print surfaces these days. (And our purple glue stick habit has become rather expensive.) So, let's put a bunch of strips of really finicky tape on the bed and apply some PEI! The very professional-looking roller was constructed to help glue packraft fabric. Stega used it ...

If only my google search history could talk... "3m 468 tape cutting" (the edges of the 1" roll are pretty blobby and uneven, I just discovered.) "3m 468 tape removal" "3m 468 solvent" The tape is down with only one ugly gap and very minimal bubbling. But wow, the e...

Winter doldrums have passed, and the intrepid dinosaurs are back to working on their printer. First up is catching up on smaller improvements to clear workspace for more ambitious mods later. That big power supply sure does fill up the interior of the printer. Let's add some 92mm case fans to the si...

Usually you can find someone willing to ship USPS. Haven't found one for small parts though.

I do have a water cooling block intended for the extruder motors. Did you find any particular thermal epoxy to be good or bad, jdurand? Thanks!

This printer continues to be the most fun/frustrating/fun you could ask for! So far, we've learned that making long continuous smooth bends in acrylic (such as one might want for a shape-conforming enclosure for a Rostock Max V2) is a task for people with appropriate skills and tools. The dinosaurs ...

That 99705 in my screen name isn't just for looks! I used to live there, went to HS in North Pole, left for 2 years in the AF, then joined the guard at Eielson. Also worked for the school district for 5 or 6 years. Spent 17 years total up there. I remember when 2geeks really was just a couple guys....

What part of Alaska? Fairbanks, pretty much in the middle of nowhere. I am still enjoying the dinosaurs and the way you write. Very informative but with a little added humor. Great Job! Thanks, this remains an incredible amount of fun! Right now we're learning that tiny dinosaurs have very little n...

The printer has been using the 1300W power supply for a while, with it just sitting outside the printer and wires running in. The bed performance is amazingly better, and has no problem achieving and holding 110C. The new power supply fits nicely inside the case! (Heat bed cozy also pictured.) The o...

[img]http://gchristopher.net/3dprinting/bottom_bracket_print_fail_small.jpg[/img] This is a picture of two attempts at printing a corner bracket for an experimental heated enclosure for a Rostock V2. Both were printed with ABS on a Rostock V2. The bed was glue-stick coated for all attempts. The fir...

FWIW, the 600W Diablotek I received worked just fine, but I swapped it out for a 1300W EVGA to support higher bed temperatures and hopefully a dual extruder upgrade.

Vacation is over and filament was the number one present. So, the Dinos are back in business and working on upgrading their printer to learn and try more adventurous prints. (And also the printer is a giant toy.) Today's experiment was with bed heating times! Who wants to wait a half hour for the be...

Thanks for the warm welcome, everyone! This has been a great experience. ... where the HELL did the rogue monkey come from Let's see a little more of the monkey! :) The flying monkey arrived in the mail from an ex I hadn't seen in years, with a note that his name was Captain Fancypants and I was NOT...
