I use no fan for the first two layers then fan on for the rest if the layer time is less than 60 seconds. It's needed for overhangs and small cross-sections. I saw a significant increase in print quality with it, and it should be standard in kits people sell. I use 1:4 watered down PVA glue on the heatbed = zero warp even for large parts. Turning the 40mm fan on drops the temperature of the hotby ajayre - General

My suggestion before choosing where to buy from anyone is to look at their support forum (if they have one) and see how good they are at answering customer's questions. You will need to calibrate the printer after building it to improve the quality of prints. Andyby ajayre - General
Why not print from a $35 Raspberry Pi instead? More convenient than continually inserting and removing SD cards IMO. Andyby ajayre - General
I noticed a similar issue. With the RPi powered from a cell phone USB power adapter it would sometimes reset when the tumble drier turned on. Since switching to power from Melzi no issues. Although I am thinking of adding a UPS to be absolutely safe. Andyby ajayre - Developers
My recommendation for this is to make the code modular. Printrun is a good example: - low level python library for communicating with the printer - mid level command line interface (uses the library) - graphical interface (uses the library) This makes it easier for other people to use parts of your work for their own purposes (if it will be open source). That in turn results in more populby ajayre - Developers
I've now switched to using pronsole over ssh. I find it to be much faster, responsive and easy to use than pronterface. I can run it inside "screen" so I can detatch the ssh session and log out while the RPi keeps printing. I use a N150 wifi dongle to connect the RPi to my network. Nice and small. The Melzi board has a 5V output on the pins used for reprogramming and with a hacked USB cable thiby ajayre - Developers

I have the same printer. I followed the instructions exactly and it works very well. I didn't add anything. I think the critical aspect is that they cannot move and touch one of the legs to the metal block. I've heard of that causing melting of the metal block which is a bit scary. Andyby ajayre - General

I have a need to print out individual letters at small sizes. The letters need to be filled in and of varying sizes. I've tried printing Microsoft Sans Serif at 5mm high to 10mm high and each size has different problems. For example no infill because the width of the strokes is not a multiple of my extrusion width, or blobs on the intersection of lines on the "N" as the slicer attempts to fill iby ajayre - General

I've frequently found that printing using a RPi and sending gcode over USB randomly stops during a print. Pronterface shows an error that it can't talk to the printer. The printer and the RPi seem to still be running but there are no error messages from the printer (Marlin). A restart of Pronterface and a reconnect get the printer moving again (until the problem reoccurs). If I print using my Atby ajayre - Developers
I think it would be better to mount the extruders on the frame and then use two bowden cables down to the hotends. This is how the RepRapPro Mendel supports three print heads and I suppose could be easily adapted to your suggested arrangement. Andyby ajayre - General

I've posted the steps I've used to set up my Raspberry Pi for controlling my printer. I took the following approach: Windows PC (3D CAD, Slic3r) -> Server (gcode) -> RPi (pronterface) to avoid any heavy processing on the RPi. I've found that pronterface can send the gcode via USB fine without any blobbing or defects. Andyby ajayre - Developers
