Milly - the small CNC
Well there were at least two reasons that lead to this project. I was playing with different kind of GRBL controllers based on STMF1 Blue Pill and ESP32 and i wanted some hardware to easily test them. On the other hand i was cleaning up the workshop in the basement from former CNC projects and found some leftover linear guides, trapezoidal spindles, NEMA 17 and 23 Steppers etc…
After drawing down some ideas i ordered some aluminum extrusion s matching the 300 and 250mm rails i had laying around. With the pfofiles odered to the matching length i finalized the drawing of the small Milly CNC with a footprint a bit bigger than an A4 paper.
The Plan is to fit all needed electronics into the base of the CNC. This means the power supply for motors and spindle as well as the full CNC controller. I guess it will the the GRBL ESP32 with SD-card and Webinterface/Wifi, which makes this machine completely self contained.

Ich garantiere bei meinen Bauberichten und Teilelisten keine Vollständigkeit etc...es wird aus den Teilen gebastelt die gerade herumliegen.
Bitte keine Anfragen zum Bau/Fräsen von Frames, Teilen oder sonstigen Aufträgen. Ich betreibe die Seite rein als Hobby und nutze die zur Verfügung stehende Zeit gerne für meine eigenen Projekte.
Bei einigen Projekten werde ich zu gegebener Zeit die Pläne veröffentlichen - aber auch hier lasse ich mich ungern hetzten ;-)
No waranties for completeness of any contructions, part lists etc.. I build from party i have just lying around in my workshop.
Please, No requests to buy frames, builds, etc.. I run this page in my spare-time and as hobby only. Want to keep my free time to work on my own projects - sorry
I will release the plans for some build at some point in time, but again, please don't ask for unreleased plans, i don't want to get rushed ;-)
