Hello all!
I'm planning to build CNC machine, using Cindymill model (
Cindymill | A gentle way to start your journey into CNC milling.) as a base. I did a little redesign to fit some parts I already have:
-Hiwin 2x750mm rail MGN15R and 4xMGN15H blocks
-PMI 2x300mm MSA15R rails and 2xMSA15S blocks
-SFU1204 300mm ball screw
Main differences between Cindymill and my design are:
-using MGN15 and MSA15 blocks instead of MGN12
-using 4040, 4080 and 3060 T8 profiles rather than T5 versions
My remix of Cindymill model is available here:

This will be my first CNC machine, although I've build couple 3d printers and have some experience in milling using commercial solutions. Actually I'm planning to use one to mill all the aluminum parts (blue color in 3d model). I want this machine to work mostly with wood and occasionally with aluminum. The spindle I'm planning to use is water cooled G-Penny 1.5kW (not 2.2kW as in file) - with 1.5kW dust collector it should work fine connected to single phase (3.5kW max)
If someone with experience could look at the model and parts and share their opinion/suggestions.
My biggest concern is if I should go with SFU1610 ball screws instead SFU1605?
I will choose motors later, I'll go with Nema23 size
I have DMD560-SV drivers already, planning to use 36 or 48V to power drivers and motors.
Other question is if only two PMI MSA15S blocks will be sufficient on Z axis.
