Congrats on the build! I have a few questions: is the BLDC spindle from the old CNC any good? You said it burned off. Is the spindle the limiting factor when taking bigger cuts or the ridgidity of the machine?

[@keanorobotics9219]

the BLDC from the old CNC is working great and the spindle that burned off was the brushed dc spindle. In my old CNC, the rigidity is the limiting factor. If you have a much more rigid machine the 500w BLDC spindle can achieve a lot more with much better surface finish.

@@keanorobotics9219 and which type of alluminiun use?

[@keanorobotics9219]

I'm using 5083 aluminium because that's what my local supplier has. 6061 aluminium would do fine too.

Awesome job! I would really like to build your exact machine. Any chance you are going to provide a information, stl's and bom? Your looks really robust!

[@keanorobotics9219]

It's still a work in progress now. I might publish the building instructions for it if there is enough demand from my viewers. I'm glad you like my design, really appreciate your kind words :)

@@keanorobotics9219 could you provide links for the linear rails and ball screw you used? It would be much appreciated! Thanks!
