Preface

Our goal was to build a multifunctional 4-axis machine. From idea to successful operation took quite some time. We will not bore you with the description of all the failed prototypes we have built. Several times we had an apparatus that worked well, but was rather difficult to build and even more difficult to explain how to build it. Repeatedly, we re-started from scratch. Finally, we dare to say now that everybody who can drill a hole in an MDF baseplate can construct the Z99.

Some examples for using are:

• Drawing on screen and large format plot output, up to A3+. • Plot a PCB with etch resist ink. • Plot a circuit with conductive ink. • Plot a large format poster. • Cut vinyl letters. • Cut paper. • Drill holes. • Mill a PCB. • Engrave, cut and make a solder pad masks with a laser. • …

Most of the components stay the same for all functions.

Two main factors contributed to the success of creating a precision apparatus:

• 3D printer

Ordinary people, like the author, are now able to build complex 3D parts at home. A few years ago, we could only dream of this possibility. Just as important is the advent of advanced free 3D creation software like OpenSCAD (www.openscad.org).

• Spare parts for 3D printer

Not only are 3D printers widespread now, but also all the parts to build them.

All the construction parts are available on various websites like eBay or AliExpress and many others. There are no hard to get or very expensive parts used in this project. Most of the parts are also used in 3D printers.

About the name Z99

All the options use the same XY mechanism. The only component with some differences is the Z carriage. Previous names we thought of were Z3, Z4, Z5...

However, the number of possibilities is not yet exhausted, hence the name Z99.

Perhaps the number 99 is also close to the number of prototypes we have built.

How long does it take to build the machine from scratch?

The mechanical build of the machine takes most people less than half a day. However, printing of all 3D PLA parts can take several days depending on the type and size of your 3D printer.

How much will it cost?

According to the capabilities and options you require, it is much cheaper than an equivalent commercial machine. A lot will depend on the basic parts you already have at home and the place where you buy them.

Reading this manual

Several components collaborate closely for successful operation, the Windows PC software, the electronics and microcontroller code, 3D parts, motors, and constrction.

We follow this order:

• Installation of the software and source files. • Electronics, PCB, stepper motors and drivers and microcontroller code. • Printing the 3D parts. • Mechanical construction. • The PC software code, using the Z99 as a plotter, cutter, solder paste dispenser, • Drilling and milling machine. • Creating source files for working with the Z99.

Before starting to build, it is wise to quickly read through the entire manual. Afterwards start thoroughly with the beginning and go step by step through the manual.

If you don’t understand something in one section, it will probably become clearer in a later chapter.

We wish that you will have as much joy building and using the Z99 as we had in developing it!
