User Mode Introduction

Smatto Kits


In order to enable users to better use and adjust Thunder, we have opened the parameters of the core algorithm of Thunder firmware. Users can adjust the parameters of Thunder according to the usage scenarios and requirements to obtain better print quality. It should be noted that Thunder may also get worse print quality due to the adjusting of some parameters.


User mode requires using the Smartto Kits tool and modifying parameters via USB. Users can also export and share their configuration parameters with other users, or import parameters from other users into Thunder.

Here we provide a download link for the Smart Kits tool that you can download and use it by yourself. Here is how to use Smartto Kits.

1.Install the CH340 driver (the TF card attached with the printer has the driver file, or you can search and download the CH340 driver from the Internet).

2.Plug the B-type interface of the USB cable into THUNDER and the other end into your computer.

Smartto Kits Basic Menu Description


Thunder10.jpg


Import: Import Thunder configuration parameters

Export: Exports Thunder configuration parameters

Get Status: Reads the current parameters of Thunder

Use Default: Use the factory Default parameter of Thunder (print mode)

Save: The saved parameter is valid only for this time. The parameter becomes invalid after restart Thunder

Apply: Write the modified parameters to the Thunder Flash memory


Thunder UI parameters explanation Fastprint Mode

You can choose Normal mode, Fast mode, Crazy mode, User mode and Slow mode. Except User mode, all the parameters are preset by the printer. The user cannot edit them.

•First Layer Mode

Set the printing mode of the first layer (currently the default is 0.3mm height, all below is considered as the first layer). For some filament, high speed switching of the first layer will lead to poor adhesion of filament to the hot bed. It is necessary to lower the acceleration and deceleration so that the first layer can be enabled to print stably. The default mode is S4.

•Curve Mode

The default value ranges from 0 to 7. Different parameters affect the speed of the trajectory of the model. The speed of the trajectory decreases when the parameter ranges from 0 to 7, and the default value is 6.

S0~S3: the motion trajectory basically keeps running at high speed, and the speed decreases step by step; Suitable for some models, easy to cause model edge bulge; Enabling these modes will restrict the implementation of some algorithms, resulting in invalid parameter Settings.

S4~S7: The motion trajectory is slowed down to different degrees by coupling processing of multiple algorithms. The larger the parameter, the flatter the printing. It is generally recommended to use S5~S7, S4 in some models easy to cause jitter.

•Corner Line Threshold

Represents the length threshold of a small consecutive line segment at the junction of a corner (unit: mm). Line segments less than this value will have special treatment at the corner to prevent overshooting; Choosing different thresholds can well reduce the strong jitter problem caused by continuous short line segments (about 0.4~1.5mm line segments connected into a curved surface, circle or ellipse) and small angles at high speed; The parameter range is [0.01,100].

•Max Junction

Indicates the maximum startup speed when the corner between two commands is at a right Angle. When Mode 4-7 is selected in Curve Mode, the motion speed curve generated by the algorithm will shift upward or downward according to this value. The larger the parameter is, the faster the overall velocity is. Generally, the set value is between [6,40], and the unit is mm/s.

•Dynamic Acceleration(Minimum)

Represents the minimum preset acceleration of the printer, and the preset acceleration greater than this will be dynamically adjusted according to the bending degree of the movement trajectory. The value ranges from [500, 9000]. The value 9000 indicates that this function is disabled. Suitable for models that requires stable printing process.

•X/Y Frequency

Max Frequency (Hz) represents the upper limit of oscillation Frequency of X/Y axis. When the motion part set in the model moves back and forth, movements higher than this Frequency will decelerate accordingly. The frequency unit is Hz. This will effectively reduce the printer shock caused by printing small infill models. The frequency is limited to [0, 200].

Minimum Speed (%) Specifies the Minimum Speed factor that limits the Minimum amount of deceleration. Parameter range [0, 100].

•Acceleration

Compute Mode: If you choose Acceleration, adjusting the parameters of Print Acceleration and Travel Acceleration is valid. If you choose Total Acceleration , adjusting the Print Acceleration and Travel Acceleration is invalid.

Print Acceleration: Represents the default acceleration, the unit is mm/s2.

Travel Acceleration: Represents the acceleration of empty driving, the unit is mm/s2.

•Jerk

Jerk represents the starting speed of X/Y/E, where the maximum starting speed of X/Y/E can be set.

•Extruder

Max_advance_speed:Specify the upper limit of the pressure adjustment speed (LINE ADVANCE); Prevent the extruder from producing strong noise and abnormal discharge due to high speed; The parameter range is [0.1,35]; The default value is 16mm/s. Too high speed will cause extruder vibration, too low will cause printing acceleration reduction.

Advance K: Represents the K value of pressure regulation. The larger the value, the more extruder retraction will be. Generally, the remote extruder is set between [0.05,0.8], and the short-range extruder is set between [0.01,0.2].

Step 2: Insert the TF card or USB drive into Thunder, and then power on. At this time, you will see that the display screen is updating the UI. This process takes a long time, please wait patiently.

Step 3: When it prompts "Update succeeded", please remove the TF Card/ U-Disk and restart the printer. UI upgrade is complete.

Note: After UI upgrading, delete the "System" folder on the TF card or USB flash drive to avoid repeated UI upgrade during power-on.

Settings of Nozzle with Different Diameter

In addition to the 0.4mm diameter, Thunder also supports 0.2mm, 0.6mm and 0.8mm diameter nozzles. For these diameter nozzles that is not commonly used, there are some parameters that need to be set and adjusted when using the slicing software. Based on experience and validation, we offer 0.2mm, 0.6mm, 0.8mm diameter nozzle slice parameters for Thunder for user reference, see the table below (or download the Excel table).

Thunder Slicing Key Parameters & Settings


HS-PLA Series Filament "Speed-Temperature" Parameter Settings for Reference

HS-PLA is Geeetech's latest high-speed printing filament. By adjusting the melting point, melting index, glass transition temperature of raw materials and optimizing the production process, Geeetech enables HS-PLA to have stronger fluidity, smoother discharge, faster curing and forming speed and is not easy to deform under the melting condition. Compared with ordinary PLA, HS-pla has the advantages of faster printing speed, higher printing quality and more delicate model surface, which can better meet the high performance requirements of high-speed 3D printers for filament.


Due to the differences in slicing parameters, environment and printers, the following table is for reference only.

X/Y Axis Closed-loop Motor Calibration and Abnormality Elimination

Thunder 018.jpg


X and Y axis motor are all closed-loop controlled, and the closed-loop control sensors on the motors have been calibrated before delivery. Do not remove the closed-loop control sensor if the X-axis and Y-axis are not abnormal. Otherwise it will cause the calibration parameters of the closed-loop control sensor on the X-axis and Y-axis to be offset, resulting in the X-axis or Y-axis stuttering or abnormal jitter during the printing process.


On the screen menu, we provide the X-axis and Y-axis closed-loop control sensor calibration function. The specific path is "Operate" → "Motion". In the "Motion" menu, you can see two buttons "X Encoder Cal" and "Y Encoder Cal". They are X-axis and Y-axis closed-loop control sensor calibration buttons respectively. The specific calibration methods are as follows:

X axis: First, ensure that the hot end can move smoothly on the X axis, and then move the hot end to the middle of the X axis. Then click the "X Encoder Cal" button, and the control panel will pop up to prompt whether to confirm the calibration of the X axis closed-loop control sensor. Choose "YES", and the hot end will move first to the right and then to the left. When the hot end stops, the calibration is complete, and the UI will prompt that the calibration is complete.

Y axis: First, ensure that the hot bed can move smoothly on the Y-axis. Then, move the hot bed to the middle position of the Y-axis, and then click "Y Encoder Cal" button. The control panel will pop up to prompt whether to confirm the calibration of the Y-axis closed-loop control sensor. When the hot end stops, the calibration is complete, and the UI will prompt that the calibration is complete.

Daily Maintenance and Usage Suggestions

To ensure THUNDER to work optimally, maintain it after you use it.

1. Regularly add lubricating oil to the Z-axis screw, can reduce the friction between the moving parts, reduce the wear of the screw.

2. Regularly check the tightness of X-axis and Y-axis belts, and adjust them according to the situation to prevent printing split-layer problems caused by belt relaxation.

3. Regularly check whether the X-axis, hot bed and hot end are loose. If they are loose, please use a wrench to adjust the eccentric nut on the X-axis, hot bed and hot end, and re-fix the X-axis, hot bed and hot end.

4. The printer should be placed in the appropriate temperature environment for use, the environment temperature is too high or too low may affect the normal work of the printer.

5. Please turn off the power supply in time after using the printer.

6. If you do not use the printer for a long time, please pay attention to the moisture-proof and waterproof treatment of the printer.

7. When taking off the printed model, please wait for the hot bed to cool down before taking off the model. Otherwise, the PC film on the building board will be torn.

8. If the filament adhered to the surface of the hot bed is difficult to be scraped off with a shovel knife, it is recommended to heat the hot bed to about 90℃ first, so that the filament adhered to the hot bed surface are softened, and then the adherent filament are easy to be cleaned up.

FAQ

Nozzle discharge abnormality

1. Filament is knotted and stuck, and the feeding is not smooth.

2. The nozzle temperature is too low and does not reach the required melting temperature of filament.

3. There is carbonization residue in the nozzle, please replace the spare nozzle.

4. The heat dissipation of the nozzle is insufficient, resulting in the filament in the upper part of the pipe melting in advance, and the extrusion force is insufficient. Please check whether the cooling fan works normally.

5. The printing speed of model slices is too fast, and the nozzle extrusion speed cannot keep up with it. Please reduce the speed.

6. If the nozzle extrusion is not smooth due to scraping, please use the nozzle cleaner to dredge the nozzle after preheating.


The extruder gear slips and makes abnormal noise

1. Nozzle blocking, refer to the "nozzle discharge abnormality" treatment.

2. Check whether the friction force of extruder gear to filament is enough, please clean up the gear residue.


First layer abnormal

1. The first layer does not stick: the nozzle is too far away from the hot bed, please adjust the hotbed leveling again.

2. The first layer is not discharging, and the hot bed has scratches: the nozzle is too close to the hot bed, which is easy to damage the nozzle. Please level it again and check whether the discharging of the nozzle is normal.


Layer shift

1. The printing speed of model slices is too fast, please reduce the printing speed.

2. The belt of X axis or Y axis is too loose, please adjust the belt tightness.

3. X axis or Y axis synchronization wheel is not secured, please adjust the machine meter on the synchronization wheel.


X/Y axis Closed-loop Control Abnormality

During the using of THUNDER, if the X-axis or Y-axis is stuck in the process of movement, it may be caused by the following two reasons after excluding the non-pulley structure and improper connection of wiring:

1. The X-axis motor or Y-axis closed-loop control sensor is not calibrated or the calibration parameters fail, the closed-loop control sensor of the corresponding axis needs to be re-calibrated.

2.The magnet of the closed-loop control unit of the X-axis motor or Y-axis motor is loose or falls off. The magnet needs to be fixed on the motor shaft with glue again.
