This update mainly enhances the stability of the VPJet4.0 Wall Printer during the printing process, as well as the time and logic of UV lamp curing irradiation. Specifically, updates are required for the main board CPU program, main board FPGA program, headboard CPU program, headboard FPGA program, and DXonJet control software.

Enhancing The Stability of The Wall Printing Process in All Aspects

Due to the ultrasonic sensor on the printhead continuously transmitting distance data to the CPU, the printhead of the wall printer is always kept at a certain distance from the wall. If the wall printer is printing on an uneven wall surface, the printhead will frequently move back and forth in the Z-axis direction, thus subjecting the entire printer body to impact forces. The printer may therefore shake, or even experience resonance, resulting in decreased printing accuracy.

The VPJet4.0 wall printer from DXonJet Company now has a more robust body that can withstand a certain amount of impact. The updated program reduces the impact force on the body by lowering the Z-axis motor speed. Additionally, increasing the dwell time of the printhead at the top and bottom helps prevent body resonance.

Testing by the DXonJet team has shown that this update greatly improves the stability of the VPJet series wall printers, ensuring print quality is maintained.

Improving UV Lamp Curing Efficiency And Logic

We have optimized the effective exposure and curing time of UV lamps, reducing overexposure time and thus improving exposure efficiency while saving energy.
