Hi,
My late reply way I had flue over January.
The CNC is home built, revamped from an earlier build, I will use as it is for the moment but If I install a 2.2kw motor I intend to beef up the "Y" axis gantry with a "U" shaped 12mm Aluminium form around the underside to give added strength, and the uprights will construct from a 5mm and 25mm and 5mm sandwich to make a box section, at the moment it is pretty rigid, also the "Z" axis assembly will be thicker Aluminium and I will put a 300mm leadscrew and 16mm supported rails instead of the 8mm at the moment, I don’t want to run as if it was a Bridgeport but just as a hobbyist.
I enclosed a couple of Autocad sketches of my revamp, the base is wood but will be 2” thick and bolted to a frame for added strength.
The main construction is Aluminium.
When I cut the MDF profile I was getting some vibration, mainly when got to end of stroke and stepped into the next cut.
Found out later I hadn’t secured the Y Axis Nut to the Lead Screw OOPPSS.
I want to install a 2.2kw Square motor with VFD supply, what is the main difference between the Cylinder Type Spindle Motors and the square type is it just cost.
Regards and many thanks the comments have been very helpful.
