Those who want to enhance their print quality often face the problem that calibration can be quite tedious. Messing through 10'000-line configuration.h files and such stuff.

Meet Teacup Firmware. It puts all its emphasis on print quality, high performance and ease of use. In the latter area it introduced now Teacup Configtool:



Adjust - build - upload, each with one click. No messing with files, no messing with M-codes, no messing with EEPROM (what's that?). As a nice side effect, this firmware is efficient enough to blast out some 48'000 steps/second for a smooth run on ATmega based controllers and also fits into controllers as small as an $5 Arduino Nano.
