It sounds like you're past the hardest part (alignment). Here's the technique I used to tune acceleration (I assume you're using Marlin). I created a simple g-code file: G1 Y100 F5400 G1 Y100.7 F5400 (repeat these two lines hundreds of times) Your numbers will probably be different. I started with different numbers then adjusted them until I hit the worst case: the motor and bed stood still (thby tbfleming - General
Are you using the laser-cut Y carriage with the aluminum bed? I had this same issue. The carriage is overconstrained; if the pieces aren't perfect (mine weren't) it creates a slight twist which causes binding. The binding from the twist can't be fixed using the brass bushings' adjustment feature. Also, the belt attaches at a point which causes the carriage to flex the brass bushings into a differby tbfleming - General

What about rack-and-pinion? Spans long distance, doesn't have the acceleration problems that screws have, and is reliable. A lot of home-built CNC routers use rack-and-pinion.by tbfleming - Developers
If you're using PLA, then infill density, number of shells, and extruder steps-per-mm can all effect color. The more dense the print the more rich the color.by tbfleming - General

Odd, I have no problem with that bridge in ABS. PLA, on the other hand, has always drooped badly for me at 15mm. I haven't tried printing with a fan though.by tbfleming - General

Thanks for debunking this. I have, at times, produced parts like those on the left. After tuning Skeinforge, they looked like parts on the right. That picture should be used to show what can happen when some of Skeinforge's unintelligibly-named ("moon phase over car color") parameters are set too high.by tbfleming - Reprappers
Be careful: double-sided tape doesn't protect the acrylic bed like blue tape does. If your nozzle gets too close, it will melt through both the double-sided tape and the bed. If it touches, it will be like a hot knife through butter, creating both a hole and causing the bed to warp. I've ruined several acrylic beds this way.by tbfleming - Reprappers

Great! I suspect 5D on Arduino is well on its way toward becoming the most-favored firmware.by tbfleming - Experimental
I can't wait to try FiveD on Arduino once it supports non-integer steps-per-mm; rounding that to an integer on my machine would cause holes that are 100mm apart to be off by around 1.5mm.by tbfleming - Experimental

Ah! d38c995 is the source zip. You clicked the "download .zip" button instead of the link I circled (send-gcode-2010-09-27.zip)by tbfleming - Experimental
It's in that zip file. It's possible that an overly-agressive browser or security package strips it outby tbfleming - Experimental

That test code is designed for the AD595; it won't work correctly for thermistors. After your adjustment, the further you get from room temperature, the further the reading will be off. Also, did you add a 4.7k pull-up resistor? The extruder board includes it (see "Temperature" section) but the Mega doesn't. The pull-up is necessary for correct operation.by tbfleming - Reprappers
