BTW., I think most other RepRap firmwares set an divider of 8 for the step interrupt, so timing is not entirely as accurate as with Teacup, but the 32 bit extension can be avoided. They then get maximum delays of (1 / F_CPU) * 65535 * 8 = 0.026 s = 26 ms. Translates to a minimum feedrate of 38 steps/second or 288 mm/min on a half-stepping, belt driven axis. With Teacup, I've done successful movements at F0.1 (for EDM) already.

Will that be the same for an arduino mega2560 with 16Mhz?

whats the new pulse width if it had changed?

What about comport connection speed bottleneck? For currect firmwares it's not higher 250000baud. Thar's too slow for "high density" gcode and some of us are forced to print from sdcards for better prints.

I think that bottleneck is in the electronics rather than the firmware. Doesn't hardware with built-in USB chips, like the atmega32u4 on the Teensy 2.0 (and perhaps the at90usb1286 on the printrboard) ignore the baud rate and communicate at up to the full speed USB of 12Mbit/sec? With pronterface or pronsole, I can connect at "9600" to my Teensy2.0 and communicate with visually undetectable latency.

Is it possible to use teacap at all?
