Wiring diagrams and schematics

Connecting PC power supply to Arduino and Shield

The CNC shield can accept any DC voltage from 12V to 36V. Because the steppermotors used here are very small, the 12V does not need to be high amperage;500ma or larger will probably be sufficient.

Samsung dvd writer drivers download for mac. To power the upgrade, I used a power supply designed to run an internal PChard drive, although a full-size PC power supply would work.

The most important part of the power supply is that is can give 5V at severalamps to power the laser.

The CNC shield electronics can then be powered from 5V as well, but I choseto power them from the 12V rail of the power supply. If you choose to do that,you will want to adjust the current-limit on the drivers to avoid damaging thestepper motors. Details of how to do this are in the video.

Connecting stepper motors to the shield

The connector for the stepper motors are between the “drivers” (the red square circuit boards in this image.

With the white wire facing up, match the 4-pin connector on the cable to the4-pin connector on the board for both the X- and Y-axis.

Connecting laser to power supply and CNC shield

The SPNEN (SPiNdle ENable) pin on the shield cannot power the laser itself, soI use a circuit with a transistor to power the laser from the power supply, butstill allow it to be turned on and off by the CNC shield.

First, you will connect the positive wire of the laser (coloured red on mine) tothe 5V power line from your power supply. It MUST be 5V, any more will damagethe laser!

We will switch the laser on and off by connecting or disconnecting thenegative/ground wire. This technique is known as “low-side switching”.

Here are two ways to do it, though there are probably other ways too. Irecommend using a MOSFET over a TIP120. But if you only have a TIP120 it willstill work though your laser power may suffer.

MOSFET circuit

An efficient way to switch the laser on and off is to use an N-Channel PowerMOSFET. Currently I am using an IRF520 module like this one, but this is not designed for logic-level switching so if you have the option I wouldrecommend using a logic-level MOSFET instead.

But, regardless of the voltage, if you want to solder one yourself then thecircuit will look something like this:

This will switch the laser on and off with a minimum of voltage loss.

If you use the same IRF520 module that I did, here is how the wires areconnected:

TIP120 circuit

Before using the MOSFET, I was using a TIP120 Darlington transistor. This worksbut it is a poor choice because the voltage drop on a TIP120 can be as much as2V in some cases. If we were switching 48V then that wouldn’t be a problem butfor a 5V laser, losing even 1V is going to severely impact laser power.

Here is the TIP120 switching circuit I used before:

The transistor I used is a TIP120 “Darlington” transistor. It is a very common“power transistor” that you can find at any electronics shop (Radio Shack,Fry’s, etc) and everywhere online. You can use any similar NPN-type powertransistor (such as the TIP31, etc) as long as it can handle the current. Astandard 2N3904 transistor can’t handle it, and while a 2N2222 may be able tohandle it for lower-powered lasers, I would still recommend using a TIP-series transistor because they are still very inexpensive.

Note: I should really upgrade the above circuit to use a MOSFET insteadof a power transistor. It shouldn’t be that hard adapt it usingthe example from this page. It may alsolet us use PWM to control the intensity of the laser.

Orientation

The origin (X/Y at 0) coordinates should be at the lower-left of the of thestage. “Lower” here means nearest to front. Make sure moving each axisnegatively will move toward that point, and moving each axis positively willmove away from that point.

configuring grbl to work in positive space

For J Tech Photonics Laser Tool (in Inkscape), make sure to set the machinecoordinates system to operate in positive space. You will do that byuncommenting the following line in config.h before you upload the grblcode to the Arduino:

Cheap laser engraving machine and cutting machine?

Neje Dk-8-kz Software Download Mac

Many users only pay attention to laser power and area, as well as price and video when purchasing products. However, they often buy unsatisfactory products. Currently, more than 90% of engraving machines on the market are products developed based on GRBL open source solutions. Many companies avoid the development process and use grbl directly for laser control. Since there is no need to develop a control system, it can bring very low costs. Although GRBL is a well-known control system, it has many disadvantages in controlling lasers. Laser control is difficult, it takes a lot of time to learn professional g-code knowledge and grbl software, and it takes more money to buy professional software, such as lightburn software; the acrylic structure is easy to damage during transportation and use, and it is easily damaged during transportation and use. It is easy to deform with the passage of time, resulting in poor mechanical accuracy and short life. They use cheap second-hand laser lasers, which are exposed and easy to assemble, without reliable cooling systems, process standards, professional knowledge and technology; more importantly, after-sales accessories support and warranty;

Is a larger area better?

In fact, you need to consider your actual use. If your application is based on engraving, I suggest purchasing a design with a lighter module, such as the master 2 mini. This design structure can scan faster than the master 2/ 2s or plus is twice the speed, because the weight of the module is light, so the maximum mechanical performance can be maximized and the jitter is smaller. If you want better engraving speed and cutting function, I recommend the master 2/2s 20W version. The module weight design and module power have a good balance. The gantry structure is more suitable for cutting, with a large area, but the engraving speed Because the module is relatively heavy, it cannot be adjusted too fast. If the speed is adjusted too fast, exceeding the maximum limit that the machine can actually accept, it will cause severe jitter. The neje series of products, from master 2 mini, master 2/2s, plus, mix, max, is a balanced transition from engraving to cutting performance. You need to consider your own application requirements, and choose lightweight ones for fast speed. Don't believe in the performance of the so-called 32-bit control chip. The only performance that can be improved by 32-bit is the moving speed. The cutting speed is determined by the laser power, and the engraving speed is determined by the weight of the module. Although NEJE has all been updated to the 2s version, that is, the 32-bit controller, and 100% adapts to the lightburn software, including the reset function.

-Speed about “Fast” and “Slow” modeEvanator (2020.11.15)

Hello, fast mode and slow mode are to solve the problem of module weight. The 20W module weighs more than 200 grams. Although it is already very light in similar modules, it is recommended to use a slow module with this module, but If it is a 7W module, because this module is relatively light and will not cause shaking, a fast module is recommended. The choice of mode is determined by the weight of the module. Neje has optimized the motor accelerometer to the greatest extent. If you have requirements for speed, it is recommended to use the neje master 2 mini machine, which is twice the speed of the neje master 2, because this machine The mounted module is very light and can be scanned quickly without shaking.

Is the recent version of the Neje master 2 plus 100% compatible with Lightburn software?

Currently master 2, 2s, master 2 / 2s plus, master 2s mix, master 2 / 2s max are 100% compatible with lightburn, and the 2s version is 32-bit, and the performance is 50% higher than stm32;

Can you tell us when the 32bit board may be coming out? I have read it doesn't increase speed much, but it would make pictures come out better. Like better detail and better shading. I would like to see a video of the 30w module engraving a portrait or something in the future :) I really want a master 2 Evanator (2020.11.5)

I am glad to discuss this issue with you. At present, the amtel motherboard can control 255 laser power levels. The 32-bit chip can theoretically subdivide more levels, but in fact, 255 laser power levels and 1000 power levels have almost no engraving performance. The difference is that the laser current and power are not absolutely linear. Under this resolution, the engraving effect is no different. Please don’t be misled by the so-called 1000 resolution. If you pursue better details and grayscale, you need to pay attention to the module. Wavelength, optical design, mechanical accuracy and movement speed, master 2 mini, 405nm laser can bring better grayscale and detail, because the absorption efficiency of 405nm wavelength can present better details. Neje will update the 2s version of the motherboard, and the master series will be updated. Customers who bought before, please don’t be disappointed. NEJE pursues engraving and cutting quality and does not have hardware performance. However, under pressure, it will also upgrade the control chip, but please believe, master The 2 series has the most perfect carving quality.

Are the 30W and 40W compatible with the NEJE Master 2?

Support, but need to install a sliding slot slider.

Laser power controlled by 255 or S1000 steps?

In the benbox control mode, the laser power is 0-L255, which means the power is 0-100%; in the GRBL1.1f control mode, the laser power is S0-S1000, which means the power is 0-100%.

About STM32 and atmel chips？ (2020.10.31)

Regarding the 32-bit stm32 and atmel chips, atmel is the original grbl dedicated chip. The stm32 chip can increase the main frequency and can indeed increase the movement speed of the machine, but there is no increase in cutting speed and engraving speed! why?

Compared with atmel, the actual increase in cutting speed and engraving speed is not obvious. , Because the cutting speed is determined by the laser power, the engraving speed is determined by the weight of the module and the sliding module. The performance of atmel is completely sufficient!

So, don’t worry about your atmel performance is not strong enough.

Later we will upgrade this chip on all master machines. The chip performance is 50% stronger than stm32. The improvement that can be brought to the current machine is the increase in motion speed. Motherboard interface is compatible with existing machines.

20W laser fan stop working？ (2020.9.2)

Neje Mini Engraver Software

Note: For the New NEJE 20W laser module, the working status of the fan is determined by the temperature of the module, and the fan speed is dynamically adjusted according to temperature changes. When the machine stops working, the fan will stop working when the laser temperature drops.

The laser module power is not the higher the better(2019.12.30)

The NEJE laser module is developed according to the actual process requirements. When you choose a laser, it is not necessary to use more power. For example, the NEJE 405nm 3500 module has a high power of 405nm and a very small focus. The short wavelength of 405nm is easier to Material absorption, all effects and precision are the highest. Its process features are high-precision engraving, gray-scale engraving and high-precision drawing images. The disadvantage is the average speed; 7W modules are good at high speed because of their light weight, small focal length, small focal point, and high power. Deep engraving, suitable for engraving logos and patterns; 20W module has a small focal point and high power, but is relatively heavy. It is good at slow depth engraving and cutting wood and paper pieces less than 5mm thick; you need to consider this according to your actual needs Several modules.

About NEJE Master Mechanical.(2019.12.30)

The actual mechanical area of the NEJE Master engraving machine is 170mm * 170mm. Software will be upgraded later to adapt.

NEJE machinery uses composite materials and CNC technology, the pads are designed with silicone, and the 4 feet have fixed hole design, which guarantees accuracy and stability. The technology of other manufacturers' acrylic materials is laser cutting, the accuracy is poor, and over time, the acrylic will bend and deform, and the accuracy of the machine becomes worse and worse.
