Your Kit will come with:

Powerful X, Y, & Z micro-stepper motors size 34 with 1200 in/oz. of torque to prevent any loss of steps. The minimum possible motion is .0001” with a minimum speed of 0.5” per minute. The maximum speed is 50” per minute.
X & Y Axes Zero Backlash Ball Screws with pre-loaded ball nuts to eliminate play on the table travel, and provide precision machining
Z Axis pre-load arrangement to eliminate backlash on the up/down travel

This unique design of direct drive keeps the user without having the need to change the belt or adjust as it wears down.
No bulky large motor brackets that house the belts on the X & Y making your machine easy to convert
Full 3 Axis coordinated motion control, or hand-operated control
Easy-to-follow instructions with pictures to convert your mill
Easy precision alignment setup of the X & Y ball screws to your machine

Other Features of CNC Jr Retrofit Kit:

Pre-engineered for you when it comes to pitch and resolution. No additional parameters set-up required. Display resolution is 0.0001 micro-stepping travel.
Since this is not a complicated servo system, you do not need to tune up anything for optimum performance. Our design uses a micro-stepping system "already" pre-designed for optimum performance.
Ready-to-Operate System: As soon as all hardware conversion on your mill is done, install the software on your PC, plug the Control Unit to your PC, turn it on, and you are ready to program your tool path to machine!
Runs files from popular CAD-CAM softwares that produce standard G-Codes such as Mastercam, Surfcam, etc to machine and engrave intricate and detailed parts
Load DXF files from graphic programs such as CorelDRAW into CAM softwares to machine or engrave detailed parts from scanned images
Easy to Use Jogging Features and Feed Control
Jog-Input Command automatically writes each line of your toolpath as you manually jog each axis by pc mouse, keyboard, or the optional hand held remote control joystick to save as a program for repeat use.
Software Power Feed capabilities on X, Y, Z, and W with one click of the pc mouse for exact relative driving distance.
Tool Height Compensation with Automatic Quill Retraction for easy R8 collet tool change
Easily build a file of commands to machine simple parts without the need to learn or use a CAD-CAM program
Can add hand held remote control, engraving attachment, fourth axis, computer control coolant assembly--providing your machine contains a built in tank, and quick tool change, from our line of accessories to your newly assembled CNC Mill. The Hand Held Remote Control is an optional accessory which is mounted to your Jr's Z axis with Velcro.
Beginners will appreciate the user-friendly control system. Easy to learn and operate, especially if you already know how to manually mill
