Arduino as Z-Probe questions
-
That's great. And I learned, that I skip all the arduino 5V conversion stuff, and just go for an ESP module for my project
More Mhz, more memory, and free WIFI I'll never use 
-
They also make 3.3 Volt Arduino-compatible boards if you want to stick with that.
(And a Trinket USB-attached Arduino, although I've had problems with trinkets before.)

@alankilian Thanks, they are a bit too slow though. I need at least 16 Mhz

There are several Arduino boards that use 3.3 volts and have 16 MHz or better clock speeds.
I was looking at one the other day that had 1M of program memory, 256KB of ram and a clock speed of 64MHz.

There are SOME of Arduino-compatible 3.3 Volt boards that run fast available.

@alankilian Thanks for the list. However I couldn't find anything which is small, running on 3.3v and has >16 mhz. Nevermind though, The ESP should arrive today and suits all my needs for now.

Did you see this one:
No WiFi but even smaller than the ESP and runs at a respectable 64 MHz.

For 3.3v Arcuino the SMT32 blue/blackpill are a good choice. Inexpensive, good documentation, support hardware debugger, support the Arduino framework, have USB C connector (e.g. for serial output), have a builtin DFU bootloader (for dongle-less field programming), and are compatible with platformio (great dev experience).

@dc42 I've got another question I hope you can help me.
- When are the deployprobe and retractprobe macros executed? Only when a BLTouch is connected, or for the other probe types as well?

For BLTouch they are executed before and after every probing move. For other probe types, when running G29 S0 they are executed at the start and the end of the entire probing operation. They are also executed when you run M401 and M402.

Ok, thank you very much!
