Identify your Lead CNC variant

Previously all Lead CNCs were named after their machine footprint, at this moment all kits and guides follow the RatRig model notation ( which refers to the work area ).

Start by determining which Workable space you need, to understand which Lead CNC size is adequate for you.

Spoiler board is not included in the kit and needs to be sourced locally.

Take into account the maximum cutting depth ( Z height ) of the machine when choosing the appropriate CNC for your application.

The High-Z upgrade is available for all Lead CNC variants except the 1515.

Since there are multiple Lead CNC variants, our guides won't mention profile and lead screw lengths, as these vary. Instead, the guide will refer to each profile and lead screw by the names described on the table. You may want to label/group these parts right now to prevent assembly mistakes and make your job easier.

For the High-Z Mod, you should use the Lead CNC 500x500; 750x750; 1250x750 as your main guide, but instead of following chapters 1.3 and 1.4 on that guide, follow chapters 2.3 and 2.4 of the Lead CNC 1250x1250 guide.
