Hi yaer i read about it will look into his code soon but got some thinking already doen.
I targeting my local fablab so bit hier price but more prezission and durace is better.
The price list are actual ~100€ Motor 50 € Chain 20€ Sled (alu) Z-Ache ? (i think 50€ would be ok) 50 € Electrics 200€ spindle
+20% cause i screw something up
→ 580
I think this is a awesome price.
In my calculation i got around 350 steps per mm chain.
