Energy consumption and noise emissions are at an acceptable level ex-factory, but at least in terms of volume, strong improvements could be achieved with better stepper motor drivers and quieter fans.
The extrusion quantities in the extrusion test are not necessarily stable, but our measurements here can also only reflect the real behavior of the extruder to a limited extent. Active heating of the build chamber to reach higher ambitient temperatures should improve the result even more. QQ-S PRO is equipped with a 32-Bit motherboard and a separate MOS module, allowing for stable prints even at high printing speed.Overall the features of this machine are interesting, there is a silent 32bit motherboard, and an auto-levelling sensor, quite advanced features not always found on entry level 3D printers. All three stepper motors start rotating simultaneously and as soon as a limit switch is reached, only the motor in question is stopped until all three limit switches are finally reached. If you have the power button on the front left of the screen, you have a QQ (8-bit) unit, which is different firmware. To make your sale worth, we can give 100% assurance that we assist you to choose right 3D printers to meet your requirements.
When the sensor is not in use, it can be attached anywhere on the printer thanks to the strong magnets. This is partly noticeable in the print quality, as the plastic pressure in the nozzle cannot react as quickly as it should. The approximately 200 watts of heating power seem almost too little here, even though the insulation and heatspreader ensure very even heating. Thus, although the energy measurement with the Voltcraft SEM 6000 results in quite similar curves on average for the 3DBenchy test print, the individual measured values of the MKS firmware fluctuate strongly.
After the six silver steel axles are inserted into the print head arms and the base, the upper end plate is put on. In terms of print quality, the lack of stiffness and the high distance between the extruder and nozzle are the biggest causes of problems with the Flsun QQ-S Pro. According to the printer menu, the mainboard identifies itself to be a MKS Robin Mini Board and the microprocessor type STM32F runs the Marlin firmware. The factory board has 3 pin connectors for the endstops which means that you can get power to more advanced endstops as well.
In principle, the use of this version is not recommended because the firmware lacks important features.yeah I am on that, but I have no idea what values to change, as they look different in the robinmini config file, the duet firmware is on 3. With the family PC and Lego Mindstorms, my interested in software and programming took off, and I am currently an engineering program student. Another advantage is that two or even all three motors work at the same time to move the print head in one direction, following the rule: "Together we are stronger".
Great Deal
