565mm.8.Why does the printer continue to print for about 1 minute when the filament run out?
This is deliberately designed to prevent the filament from getting stuck in the filament detecting sensor, which may damage the filament detecting sensor when auto return the filament.9.What is the current of the extruder motor? How to modify the current of the extruder motor?
The default extruder current of SR is 0.95A. Use Repetier to connect the printer, enter the command "M906 T0 E (value)", and then enter "M500" to save.For example, enter "M906 T0 E800" to modify the extruder current to 0.8A.10.What is the default steps of SR's extruder? How to modify the extruder steps？
The default steps of SR extruder is 420. Use Repetier to connect the printer, enter the command "M92 E (value)", and then enter "M500" to save the steps of the extruder, for example enter the command "M92 E370" can modify the steps of the extruder to 370.11.What is the maximum printing speed of SR?
When the printing speed exceeds 200mm/s, the printing quality will start to deteriorate, so we do not recommend setting the printing speed to exceed 200mm/s.12.What is the length of the SR parallel arm?
315mm, the distance from the center to the center of the two fish eyeballs.13.What model of SR heating rod is?
24V 40W.14.What model is the thermistor ?
NTC 100K.15.What model is the SR power supply?
24V 15A 360W.16.What model of SR motherboard cooling fan is?
24V 6010 fan.
No, because there is no reserved installation interface for the second extruder on the motherboard.2.What are the specifications of the QQ-S Pro power supply?

NTC 100K.4.What is the model of the heating rod of QQ-S Pro?
24V 40W5.What firmware does QQ-S Pro use?
Repetier-Host.6.What is the length of each belt of QQ-S Pro and what is its model?
The length of each belt of QQ-S Pro is 1486mm, and the model is 2GT 6mm.7.What kind of stepper drivers does QQ-S Pro use?
4 A4988.8.Can QQ-S Pro be upgraded to other types of stepper drivers?
Yes, QQ-S Pro can be upgraded to TMC 2208, TMC 2209, etc., but the firmware needs to be updated.9.What is the length of the parallel arm of QQ-S Pro?
280mm,the distance between the center of the two fish eyeball heads.10.What are the models of the three fans on the QQ-S pro hot end?
Two 4010 turbo fans, one 4020 cooling fan.11.What is the model and size of the QQ-S Pro heating block?
E3D V6,and the size is 16*16*12mm.12.What is the overall size of the QQ-S Pro?
400X360X950mm.13.Which filament does QQ-S Pro support?
PLA/ABS(Enclose)/PETG/WOOD.14.What is the maximum temperature of QQ-S Pro nozzle and hot bed?
The temperature of the nozzle does not exceed 250°C, and the temperature of the hot bed does not exceed 90°C.15.What is the length of the QQ-S Pro PTFE tube?
780mm.16.Can the extruder of QQ-S Pro be replaced with another type of extruder, such as BMG extruder, which parameters in the firmware need to be modified?
The extruder of QQ-S Pro can be replaced with another type of extruder. You need to modify the pulse value of the extruder in the line ">EXT0_STEPS_PER_MM 367" to the pulse of the new extruder in the firmware configuration file.17.What is the model of the pneumatic connector?
PC4-01.18.Can QQ-S Pro upload the latest Marlin? Does FLSUN have Marlin for QQ-S Pro?
QQ-S Pro can upload Marlin, but flsun don’t have official Marlin firmware.
1. What driver blocks does Q5 use?
XYZ axis uses TMC2208, E uses 4988.
2.Does Q5 support printing with WiFi ?
Q5 does not support printing with WiFi because there is no WiFi module installed on the motherboard.
3.What is the length of one Q5 belt?
4.What model is the motherboard cooling fan of Q5?
5.What is the length of the Q5 parallel arm?
210mm, the distance between the centers of the two fisheye ball heads.
6.Is it possible to install a second extruder on Q5?
The Q5's motherboard has reserved ports for the second extruder, but we have not tested the installation of the second extruder on the Q5. If you are interested,you can give it a try.
7.What model is the fan on the Q5 hot end? What is the supply voltage?
The fans on the hot end of Q5 are 4010 turbo fan and 4010 cooling fan, they use 24V power supply.
8.What is the model of the thermistor and heating rod of the Q5 nozzle?
The thermistor model is NTC 100K, and the heating rod model is 24V 40W.
9. What is the model of the Q5 power supply?
24V 12A 240W.
10. What the firmware does Q5 use?
11.What is the length of the Q5 PTFE tube?
12.What is the gear model on the Q5 XYZ axes motor?
2GT 20 teeth.
13.Why are the motor and synchronous wheel of Q5 fixed together?
This can prevent the Q5 synchronous wheel from falling off the motor. If you need to replace the motor or the synchronous wheel, you need to replace all.
14.Why does the print head fall down after the print is finished?
You can download the latest firmware from our official website to solve this problem.
