This makes sense. So we always try to get perfect speed on the axis and not in the extruder. This is good.
Great work! 
Finally I used u8glib at work. This works but needs more space.
I've pushed my u8g-stuff. Maybe you can use some lines of it. There are 2 buttons implemented. Not very pretty, but better than nothing. https://github.com/Traumflug/Teacup_Firmware/tree/u8g_with_buttons
This code runs on an Arduino Nano. But I mainly pushed it for the buttons and the idea how to shift visual pages. When I remember correctly I'm at ~20k....
Just tried this with the Adafruit Display. But can't get this to work. I changed the address to 0x3C and copied the u8g working init_sequence but unfortunately I don't see...
Oh dear! I changed the address first and thought this was correct. Back to 0x78 and taking the new init sequence and everything works as expected. Thank @Traumflug
Or not :/ Friday anything looks perfect. Monday nothing works... How should the debug looks like? This is what I get: `.1.3.4.4.4.4.1.3.4.4.4.4.4.1.3.4.4.4.1.3.4.4.4.4.`
Some progress: I flash the Nano with the adafruit example. (GFX etc.) Display shows the flash screen etc. Now I flash Teacup and it works. I have connected the reset...
Sorry for the noise. It is the reset pin. Flashed adafruit example. It works. Flashed Teacup. It works. Unpower Nano Power Nano It doesn't work.
