“ files are being removed from public access at the request of the U.S. Department of Defense Trade Controls," read a banner atop the website. "Until further notice, the United States government claims control of the information.”

Manufacturing a gun at home is nothing new. People have been doing it for a long time and it's perfectly legal. Why anyone thinks a law prohibiting this kind of manufacturing would stop or slow down any evil-doer is beyond me. Rest assured, any such law would not be about public safety but about politics and government control. With about 300 million guns already in the US, it would still be

Thanks. Did a little reading on material science.. "Stiffness" is the material's ability to resist elastic deformation, while "hardness" is the material's ability to resist pla

What seems to have worked for me on my MendelMax is to connect all the extrusions together with wire and then ground the frame to the power supply ground. I've also made a connection between the power supply's V- and its ground. Lastly, I wrapped the ribbon cable from the display to my Sanguinololu in aluminum foil and packing tape as a shield, then grounded that to the frame. Note that the al

Have you contacted Blomker about this? They were really good about replacing defective parts (hot end) with my kit. Installation of the linear bearings needs a little care to keep from pushing the balls out when you install the shaft. I polished my smooth rods a little and chamfered the ends as they were not very well chamfered as delivered. This will help keep the edge from catching on the t

Generally, fewer teeth gives you more resolution and more torque. Since you have a fixed number of steps in a revolution, a smaller pulley yields a shorter linear distance per step. However, this extra torque and resolution comes at the expense of backlash and accuracy since the T5 belt is a timing belt and not really intended for accuracy and repeatability in a bidirectional pulley. The rule

Sounds like the normal toothed pulley. I have a MendelMax and not really sure about the differences but it sounds like the exact same arrangement. The pulleys I have are 10 tooth for a 5mm pitch (T5) timing belt. Like I said, I'll send them and the belts to you if you want them. Let me know.

Are you talking about the Y-axis pulley? What size belt are you using?
I wouldn't recommend using a pulley that isn't concentric. It would almost certainly show up in a print.
If it's a T5 belt and pulley you're using, I can send you a good pulley in the CONUS. I'm not using the T5 belts anymore so the pulleys are yours if you want them.

Yes, definitely try and slow your extruder feed rate. It looks to me like your extruder stepper is stalling too as you can see the gear pausing corresponding to some vibration noises.. Both those issues would be symptomatic of too much feed rate I think.

Solved (I think)...
I replaced the hardware/tools folder in Arduino 0023 with the hardware tools/folder from Arduino 1.0 and that lets me program with the "Arduino" protocol.

Apparently, the problem has to do with changing the upload protocol. If I leave it a STK500v1, I get the above baud rate message. If I change the upload protocol to "arduino" as instructed by Botronicz, I get a new message: avrdude: Can't find programmer id "arduino".
This makes sense because there is no programmer defined for "arduino"...
How can I fix this? Is this a problem because of o

Okay.. So I received my new, spare Sanguinololu board today from Botronicz. It cam with a ATMega1284P pre-programmed with Sprinter and Optiboot bootloader. From a hardware point of view it's identical to the Sanguinololu w/ATmega1284p I've been using. However, the bottloader is different. I want/need to program my own version of Marlin RC2 on this but I'm getting this error from Arduino when I

Yea.. Run the temp up on the bed a little.. I would set first layer to 115, and remaining layers to 110. Also, wipe the kapton tap with a paper towel and a little acetone before printing. This always sticks well for me (sometimes too well!).

My kit has been running along nicely. I'm still using the supplied MDF print bed and no issues. However, I did cover the print bed with an adhesive backed, automotive heat shield. I was seeing some backlash issues with the supplied T5 belts and pulleys so I upgraded to GT2 belts and pulleys (from Blomker). Backlash gone. I also had a couple issues with the X-carriage and extruder printed pa

So far, the problem only seems to be with the display freaking out. I can read and write to the SD card through a host even when the display is not working. I hope it is only the display being defective but I'm ready to shorten the cable if I need to...

I've got 3 feet of ribbon cable between the LCD and the Sanguinololu.. I spoke with the guys at Think3DPrint3D and they think it may be a bad LCD module so they are replacing it. I'm a little skeptical but I'll try it. If that doesn't work, I'll buy some shielded cable from Digi-Key and make a new cable. It's bad enough that I don't dare and try to print from the LCD module's SD card for fear

I slowed down the DEFAULT_RETRACT_ACCELERATION in Marlin from 3000 to 1200. In Slic3r, I reduced the retraction to 0.5mm, reduced retraction speed down to 10mm/s and turned on Z Lift by setting it to 0.1mm.
This is what works great for me...
