ToyREP 2 is modular design, based on REPRAP ideas. It allows to print parts suitable for 3D printers, CNC, engravers and other 3 axis machines with stress on simplicity, low cost, usage of many different types of motors, sturdiness and ease of build and alignment.
Superseeds original ToyREP in many aspects and using more up-to-date parts and technologies to make it more reliable, customizable and provides better user experience and accuracy. By preparing indepented axis, that can be joined together, it will allow to design more than just one kind of a machine and type of kinematics that will let you experiment with mechanics and shortens your designing stage.

Work in Progress Stage
For now only parts for trapezoidal rods Tr6 and Tr8 and GT2 timing belt are published, that will let you build the basic 3 axis CNC machines. No detailed build instructions, BoQ or pretested machines will be published until the project is finished. Feel free to submit your ideas and improvements or submit your requests in comments.
Right now, I have one axis printed to test the accuracy of printed parts, assembly, alignment and movement precision. More will follow soon.
Planned Improvements (no promises :D):
- Timing belt parts for T2.5
- Mount for electronics
- Mount for PSU
- Mount for heatbeds
- Mount for other tools like engraver, laser, pastestruder, etc.
- Delta kinematics
- Core XY kinematics
- Mount for two endstops
- Laser cuted covers and frames
- Published preliminary parts V2.06 for M8 threaded rod frame plus renders for 3 axis CNC and cartesian printer mechanics
- Published preliminary parts V2.06 with support for GT2 timing belt
- Published preliminary parts V2.05 for optical end mechanical endstops
- Published preliminary parts v2.04 and V2.05 for Trapezoidal rods and optical endstops only
0.4mm nozzle, 0.15mm layer
Fillamentum ASA Extrafill
ABS may be also used as it provides better overhangs than ASA

To make the long story short, this idea was in my mind for almost three years, but I was not able to continue due to workload and missing parts and development of CARP 2 which is still too far from publishing atleast as a work in progres project.
Trapezoidal rods and small NEMA 14 motors I was originaly going to use as an upgrade for TouREP were so challenging, that I rather stopped development of this project and started over again. Generic NEMA 17 Printed Axis from PacManFan inspired me tremendously. ToyREP comments and upgrades you were asking for, made me think about it as a modular design.
It will always have some drawbacks. For example it won't be as compact as first ToyREP and modularity will make it quite hard to keep just one branch of the printer, but you will get more freedom in your own application to begin with the positives. Different kinds of motors, more tools, fewer required parts, and design based on functional blocks will hopefully make you utilize this design as it will let you play with 3D printing on a different level. Thats also the reason it still keeps the name of its predecesor.
This page is mostly for basic description. For detailed instructions how to assemble the modular axis a page will be prepared at: http://reprap.org
- 28BYJ-48 stepper motors with bi-polar hack
- Round NEMA14 with 10mm long shaft
- NEMA17 with 24mm long shaft or embeded trapezoidal rod
*Optical endstops on PCB with mounting holes 19mm apart
- Microswith with mounting holes 9.5mm apart
- Tr6 or Tr8 trapezoidal rods and nuts with wide variety of pitch with or without couplers and 608ZZ or 626ZZ ball bearings;
- Timing betl GT2 with pulley resting between two 608ZZ ball bearings
8mm precision rods and LM8LUU bearings
M8 threaded rods and nuts
8mm rods attached by M3 screws and nuts
M3, M4 screws and nuts and 3mm woodscrews
Every axis is made of two printed axis end blocks and one carriage, with atleast two precision rods for linearmotion (that can serve also as frame) or with two additional 8mm rods (threaded or smooth) for additional sturdines. Carriages can be attached together by M4 screws or by M8 screws to a rigid frame.
Trapezoidal Rod Axis
Printed carriage have to be equiped with two LM8LUU bearings, Tr6 or Tr8 nut and optical or mechanical stop.
Printed motor axis end contains a motor of your choice (for NEMA 17 eqiped with printed extender) and printed or metal coupler with trapezoidal rod.
Printed axial bearing end contains two ball bearings and two printed or metal lock collars of diameter required for selected trapezoidal rod.
Either on motor axis end of bearing axis end a printed endstop holder have to be mounted and carriange (only for optical endstop, mechanical endstop is attached directly to axis end part) have to be installed so stop will move toward the endstop.
Timing Belt Axis
Printed carriage have to be equiped with two LM8LUU bearings, fixture for timing belt along with belt tensioner and optical or mechanical stop.
Printed motor axis end contains a motor of your choice and printed or metal pulley (for 28BYJ-48 also two 608ZZ ball bearings).
Printed bearing end contains two 608ZZ ball bearings and printed pulley for timing belt.
Either on motor axis end of bearing axis end a printed endstop holder have to be mounted and carriange have to be installed so stop will move toward the endstop.
