Help with Stepper, Driver, etc. for Proxxon MF70 Conversion
Hi all,
I'm interested in CNC coming from a 3D printer tinkerer. I considered buying a cheap Chinese CNC to play around with, but I think I'd learn more by trying to convert my Proxxon MF70 micromill. I understand there are cheap kits out there, but I'd like to buy high quality parts for the conversion with the thought that I can learn on this and then when I have space for a shop next year I can use the knowledge, and potentially some of the parts, for a proper hobby level table CNC for woodworking.
I still don't quite understand all that's involved, but here's what I'm thinking:

Morning. You have a lot inside your post that I will leave to others. My only writing will be about Stepperonline. I have been using them for a number of years now. Their products (the ones I am using being Nema 24/23 closed loop systems) are actually manufactured by Leadshine under license. I have had a couple of small problems, and these problems were immediately rectified very quickly. Infact one was outside the warranty period. I reckon that is stand-up good service.
Stepperonline have a series of motors, the "P" series is what they call their highest quality. I would suggest buying a kit then you won't have to choose between all the options.

The 8 wire motor is far superior to the other. inductance is what you have to look at, the lower the better because that determines the max RPM at a set voltage. so use it in parallel mode.
I would go for separate stepper drivers and a motion controller it's more flexible with the some motion controller you don't need a BOB
As far as I could find you can connect the drivers 2 and 3 directly to the UC300, but their UCBB dual port breakout board will make connections easy.
I would strong advice to install limit switches. also used for homing so you can repeat easy
I made my own system using a Planet USBCNC controller DM542 drivers ( cheap from Aliexpress ) and some 3Nm motors, yes the ones I bought have a to high inductance because I didn't know at that time 10 years ago. However the system is still working well ( not fast but for me fast enough )
