I don't know about the Polygonhell Repetier branch, or the Marlins that are used on the Rostock Max, but these firmwares should support command M500~M503 for EEPROM management. The Printrbot Marlin flavors do, and it's quite convenient to change most of these things without having to recompile ...

MatterHackers seems to have some in stock at the moment. Never had trouble with them.

What about just printing the valleys then using a spackle blade to fill them with solder paste? A guy named Jerrill just posted a proof of concept for this technique. He makes his own nozzles down to 0.1mm, and recently made a little 555 chip PCB with valleys for traces. He then used a "circuit ink ...

I've not tried it As Dear Mr. Owl said, "Let's find out." I have heard these things called a number of different names, but let's go with a fanciful one: frog toes. They are designed to latch onto the print bed, and give the minimum amount of easy knife cleanup work. I quickly mocked up a simple ...

It's almost certainly water absorbed into the plastic, and yes, it can cause pitting. The pop is the sound of it vaporizing (it's above 100ºC after all) in contact with the hot end. When not in use, store filament in airtight plastic tubs with desiccant packets. Your new filament may have included a ...

Thanks for posting photos, cassetti and mhackney. I'm already getting really good prints on another model of printer I built, but the print area is tiny and I'm looking into what it will take to make a Rostock Max my second printer for the larger parts. I figured some of the successful shots were ...

I've been monitoring this forum for a little while now, to get an idea of how mature the Rostock Max is, and what kinds of things people have trouble with: build, calibration, upgrades, print issues, etc. I appreciate the positive help-each-other atmosphere of the community. What I haven't seen yet ...

what is rasberry pi, is it something like an arduino? what are pros and cons compared to the arduino? An Arduino is a microcontroller chip capable of driving a few devices; the chances of it driving any kind of video display are basically nil. A Raspberry Pi is general purpose Linux computer (based ...

Still, I personally wouldn't recommend this printer for anyone that hasn't built a 3D printer before (it's doable, but there is a LOT more information available on other more traditional models like the mendelmax) I hope I'm not out of line, putting in my two cents, since I don't have a Rostock Max ...

Yes, baud rate is critical. The host (Printer Settings) rate MUST MATCH the firmware. I think a lot of us use: #define BAUDRATE 250000 and set that in the host too. I'm surprised to see so many firmwares using such high baud rates. There's really no value to going so extreme, is there? Some weaker ...

Just a thought, but since "all laser cutters produce tapered cuts," you might find the nut will go in more easily from one side of the board, while being quite tight from the other side of the board.
