ScribbleJ Firmware (c) 2011 Christopher "ScribbleJ" Jansen http://reprap.org/wiki/Sjfw This is a firmware for modern 3D printers with an advanced gcode pipeline. * Run-time configuration of all settings. * Advanced preparsing gcode pipeline. * Acceleration and lookahead. * "Dimension" - 5D/Volumetric, buzzword buzzword. * LCD and Operator Control Panel. * Hostless printing from SD Card. This firmware includes some portions which are copped directly from the MBI firmware, and some code that is based on code in the Sprinter and Teacup firmwares, and one large option taken from Marlin firmware. THIS COMES WITH NO WARRANTIES, GUARANTEES, PROMISES, OR CAKE. I do not recommend that you, or anyone, uses this firmware. If you do, you do so at your own risk. I appreciate any bug reports, patches, and amusing stories about how this firmware burned your house down. You can find me on Freenode IRC, channel #reprap. Or email at [email protected]. VERY IMPORTANT!!!!!!!!! Please see http://reprap.org/wiki/Sjfw for lastest full documentation.

I have a mendel-parts 100k thermistor in my bed, and an arcol 200k thermistor in my hot end.
There appears to be no way to specify different tables for different thermistors, so I have to set my bed to 70c in order for it to actually go for 55c...
I've been using Sprinter, and just upgraded to SJFW for look ahead.
I set the acceleration and maximum speeds per axis same as I had them in sprinter, but I can't even come close to maxing out my axes. I tried jacking them up and no change. I can't get the axes to stall even... (I should be able to, in order to test the maximum speeds, and then dial back from there, but as I mentioned, I can't even get close to that.
M200 X64 Y80 Z2560 E1380 ;set axis steps per mm
M201 X2000 Y2000 Z75 E1500 ;set axis start speeds
M202 X18000 Y18000 Z240 E800 ;set axis max speeds
M206 X3000 Y3000 Z100 E2000 ;set accel mm/s/s < I've tried 1500 up to 5000 with no appreciable difference.
