NENO LEADX Ultra Manual

General

About the NENO LEADX Ultra

Congratulations on purchasing your NENO LEADX Ultra basic kit!

The NENO LEADX Ultra is a CNC milling machine of the latest generation.

After the success of our simple but stable LEADX Pro, we were increasingly confronted with inquiries

about more complex and stable milling machines.

The LEADX Ultra is based on the same aluminium profiles as the LEADX Pro, but dispenses with the

roller system and the trapezoidal threaded spindles and uses high-precision linear guides and ball

screws.

In order to stand out from the competition on the market, the LEADX Ultra uses massive HGR15

linear guides that can absorb 3x as many forces as the usual MGN15 linear guides.

The LEADX Ultra uses high-precision rolled ball screws with a diameter of 12mm in precision class C7

on all axes.

For this purpose, all aluminium profiles used are made in Europe.

We wish You a lot of fun with the assembly!

We are here for You. Write to us if you don't know what to do: Support@nenocnc.ch

NENO LEADX Ultra Manual

Limitation

The information and notes in this manual have been compiled taking into account the applicable

standards, regulations as well as the applicable case law and the current state of the art.

No liability is assumed for improper assembly, wiring, commissioning, use or maintenance.

The manufacturer NENO-CNC is also not liable in the following cases:

1. Failure to follow the instructions

2. Incorrect assembly

3. Inappropriate use

4. Arbitrary intervention and modification of the components

5. Technical conversions of any kind

6. Use of third-party accessories or non-approved spare parts

The actual scope of delivery may deviate from the explanations and illustrations described here in

the event of special designs, the use of additional ordering options, introductory promotions, or due

to the latest technical changes. The obligations agreed in the delivery contract, the general terms and

conditions as well as the terms of delivery of the manufacturer NENO-CNC and the legal regulations

valid at the time of conclusion of the contract apply. Furthermore, the statutory warranty provisions

apply.

Read these assembly instructions and the operating and safety instructions

carefully and make sure several times in each step of the instructions that you

have not made any mistakes during assembly.

NENO LEADX Ultra Manual

Safety

Responsibility of the operator

The operator of the NENO LEADX Ultra is responsible for the following points:

1. The safety instructions have been read and understood.

2. The construction was carried out completely according to instructions.

3. The CNC milling machine has been properly tested before each operation and is only put into

operation in perfect condition.

4. The CNC milling machine is only used with accessories approved by the manufacturer.

5. Possible precautions (hearing protection, safety goggles, distance to the spindle, etc.) have

been properly taken before commissioning.

6. Minors have reached the age of 14 before use and a basic technical understanding is

available.

7. The CNC milling machine must be operated and stored out of the reach of children.

8. Safety devices such as the emergency stop switch must always be freely accessible.

9. If you want to make adjustments to the machine, the associated controller or various

system-guided tools, unplug the power as a precaution.

10. The owner of the machine must ensure that all persons working with the CNC milling

machine have read and understood the safety instructions.

11. The owner, as well as anyone present while actively working with the machine, must wear

protective clothing as described in this manual.

Personal protective device

Please always ensure that basic personal protection measures are observed at every company and

for bystanders.

12. Safety goggles (protection of the eyes from flying chips and broken milling cutter)

13. Hearing protection (protection of the ears from loud background noise)

14. Protective gloves (protection of hands from heat and cuts when handling milling cutters)

15. Tight-fitting work clothes (protection against accidental entanglement of clothing in spindles

or guides)

16. Secure shoulder-length or even longer scalp hair with a hairnet or cap so that it cannot get

into the linear guides and/or the rotating milling tools.

17. Protective mask (protection against carcinogenic fumes and milling dusts)

NENO LEADX Ultra Manual

Safety

Ambient conditions

Carry out the construction and operation of the milling machine only on a solid, flat surface. It should

stand securely and not be able to slip.

Make sure there is enough space around the machine so that you can work comfortably and the

machine can fully extend its travels. Also keep a safe distance from other machines.

Never touch system-guided tools or moving components during operation. Moving parts (e.g. Y-

bridge gantry) can suddenly and unexpectedly change direction. Depending on the operating

regulations, a barrier or covering of moving parts may be necessary.

Keep your workspace clean and well lit. Keep children and others away or at a minimum distance

while using the milling machine. There is a massively increased risk of injury.

Residual risk

Even if all precautions are observed, there is always a certain degree of residual risk for persons or

property.

It must always be ensured that the machine is operated with caution and caution.

For your own safety, please always ensure that you are not unfocused or under the influence of

various means that could affect your mental activity.

NENO LEADX Ultra Manual

Required tools

We recommend a set of tools needed to assemble the NENO LEADX Ultra. Of course, You can also

use complementary tools.

1. Allen key set

2. Wrench or Ratchet Set

3. Various screwdrivers

4. Possibly M5 thread cutter for recutting

5. Square ruler

6. Linear guides alignment tool (included)

7. Retaining ring pliers

8. Grease gun for linear drives and ball screws

9. Grease to grease gun

Notes on assembly

10. This guide is a generalization. Photos and graphics refer to the 1000 x 1000mm version of the

NENO LEADX Ultra. The manual also works without problems with the other two machine

sizes offered.

11. At each step, first place all components listed in the respective BOM in front of you to get an

overview.

12. In each case, it is specified whether an assembly must be built 2x. Also whether it is built

identically or mirrored, is highlighted in the instructions.

13. For the accuracy of the machine, it is particularly important to measure each angle with a

stop angle to guarantee 100% perpendicularity before screws are fully tightened.

14. If an M5 thread has been forgotten, please cut it with an M5 thread cutter.

15. If you have a dial gauge, please run all linear guides with it to guarantee a completely flat and

rectangular machine.

16. The connection of ball screw to fixed bearing is often ground to very minimal tolerances. If

the ball screw cannot be inserted into the fixed bearing with light pressure, take a sandpaper

with a fine grain size and carefully grind some material from the contact surface. Then

remove any residue.

17. The ball screw can be too short or too long after fixing in the fixed bearing to attach the snap

ring in the loose bearing. The ball bearing, which is located in the loose bearing, can be easily

moved in the loose bearing by 1-2mm in both directions using a nut from a socket wrench set

and a rubber hammer.
