Taig Lathe CNC-lized

*Some photo are from older version. Please check STL file to see current design*

Taig Lathe CNC-lized, including Y-axis to be used as mill.

Print with PETG 50% infill

Insert long 3mm screw in between Z-axis' thrust-bearings, to act as structure reinforcement.

You need following not-printing parts.

• Taig Lathe ;ppp
• Screws :)
• Wood baseplate
• Two 8x14x4.5mm thrust bearing. I use RC helicopter parts (Aligh H60R001XXT)
• T8 leadscrew 300mm, with NEMA17 coupler
• Aotoro TS18-5DN as endstop sensor
• NEMA17 stepper, stepper driver, CNC controller board & software

If using as lathe, when setting up CNC controller software, beware the coordination and home position.

X-axis: servo mount side = X+ direction ; endstop = X+44mm

Z-axis: servo mount side = Z+ direction ; endstop = Z+0mm

When setting up home position, make sure home-at-positive side.

Also, homing with X first, Z later.

And remember, cut air first to see if everything is ok.

Ver 1.02 update

Move Z-axis endstop mount from headstock side (Z-) to servo side (Z+) to better fit with usual CAM coordination system

Restructure STL file for easier parts finding

Ver 1.01 update

Rework X/Y-axis coupler, add 2mm fillet, to reduce vibration

Rework Z-axis endstop mount, move it lower it, to give better access for cleaning

Add chip-shield for Z-axis leadscrew
