I tried the prevent dangerous extruder in the configure.h but it didn't help. Basically, I need to turn off temperature checking for the bed and extrduer, right? but how? What else do I need to change for p

The confusion is that from everything I read, the endstop switch should be NC which means conn

Just test compiled both Teacup and Marlin in Arduino and found that Teacup has a really small foot print: .hex file about 18K. My question is whether Teacup supports Delta Printers or is there any plan to do it?
I am tempted to test it on Atmega328 (I know, it doesn't have enough pins, but..) just for fun.
