I am building an OB 1.4 and need to decide between an Elefu, Rumba, or Megatronics V2. Seems like the Megatronics has the following issues: 1 - Hard to get in USA - Netherlands / international shipping (this is just my preference, and not an issue for everyone). 2 - Only has 3 thermistor inputs - so you cannot do three extruders and a heatbed. It does have 2 thermocouple inputs though. 3 - Doesby rsilvers - Controllers
I don't think we have anything to complain about for 3D printer pricing. The margins are well within what is normal. The exception seems to be QU-BD, who is pricing things at 1/2 of what is normal - $999 for a printer that is almost certainly better, stronger, faster than a Makerbot M2.by rsilvers - General
I made some round objects and specified 100% infill of type concentric, and concentric fill for top and bottom layers. The inside layers are circles, as expected. The top and bottom layers are what I would think of as rectilinear. Latest version.by rsilvers - Slic3r
Just calibrate your printer to treat mm as cm. That is super simple. Then everything you print will be printed 10:1 scale.by rsilvers - General
Sounds like your dealer is the problem since they refused to replace it.by rsilvers - General
You also have to wonder if they did not sell, if they would be worth more in a year or less. Remember that Facebook did not sell when offered a billion dollars, and that was a shocking move at the time.by rsilvers - General

I am printing a giant bolt in ABS, and it is sticking well to my cloth bed, heated to as hot as it will go - about 65C.

I completed the second test. This time I made sure that the weights were closely matched through control of the extrusion multiplier. 5.86 grams for the trimmer line and 5.93 grams for the T645. That is less than 1.2% difference. This time the T645 won. I set up tow straps with my Sequoia, and the samples did not break when I took my foot off the brake and let the truck creep forward. They just sby rsilvers - General
For sure, you can't use trimmer line to make medical implants. The gasses thing is just not a concern for me any more than walking through a parking garage concerns me about carbon monoxide. The sample of another brand of trimmer line was about 1/100 needed to exceed Osha standards, and that is ONLY if your head is inside a small enclosed space, and ONLY if you keep your head in that space for mby rsilvers - General
The print got worse with the duct, so I removed it.by rsilvers - General
Made a duct - we will see if it improves the pyramid:by rsilvers - General
T645 broke. It was about 11% lighter though, so this test should be repeated with the extrusion multiplier set to about 12% higher, and then see if it still breaks first. My result so far seem to indicate that either the trimmer line is stronger, or within 12% of the strength of T645. I am not sure which.by rsilvers - General
It is not 100 USD. The BOM does not include the build table, which is especially important for this printer for two reasons - one, that is how you add layers, the table moves down. Two - the table has to move even during the layer because the print head moves up and down as it changes position. So it is misleading to use the $100 in the title of the article.by rsilvers - General
I would like to do a Bowden blower, but it seems like all of the 12v blowers are really low CFM - like 17. I would like 50-100 CFM.by rsilvers - General
I also see that a duct will make interference more likely. I am going to skip the duct and change the angle by five degrees.by rsilvers - General
Well, I would like a 120mm fan except my printer is so small it is ridiculous. I think the answer is an 80mm with an air duct to focus the air.by rsilvers - General
A fan may be ok on a small part. But for large parts, it seems to contribute to differential cooling, which increase warp. Maybe the answer is to hit the part from all sides at once.by rsilvers - General
Don't forget you can just glue cloth to glass.by rsilvers - General
I was switching between my printers, one of which had dual extruders set up, and this happened - two side by side settings stayed up no matter what printer I was on.by rsilvers - Slic3r
I have been printing PLA on tape, and ABS or Nylon on 65% Polyester / 35% Cotton RipStop fabric spray-mounted with 3M HiStrength-90 glue to thick glass. The fabric has been working well on certain parts, if I use a brim to reduce curling - I don't have heat yet. But I wanted to try Garolite LE. Taulman recommended 1/4 thick - so that it would not flex. I decided to try the 1/32 thick because Iby rsilvers - General
