Maintenance & Troubleshooting Manual
Filament diameter is too big
ANY
POLYMER
change spool
Excessive pressure on feeding roller:
filament is squeezed
ANY
POLYMER
relieve pressure
Using heated chamber: PLA will
“inflate” when exposed to temps over
50-55°C
PLA
DON'T use heated chamber when using PLA

Useful G-Code Commands
Command
Printer Execution/What it Does
G1 X100 Y100 F9000
Move to X100 Y100 at 9000mm/min
G90
Absolute coordinate system
G91
Relative coordinate system
G92 E0
Set current axis position (in this case current extruder feeder
filament position is set to zero)
M11
Enable/Disable filament sensor
M75
Start print timer
M77
Stop print timer
M104 T0 S215
Set extruder 0 temperature at 215°C , don't wait to reach it. If
T0 is omitted, it's meant applied to current extruder
M106 Snnn
Set fan speed (nnn = 0..255). If no S option, then run at full
speed.
M107
Turn off fan
M109 Sn M109 Rn
Set current extruder temperature, wait until you reach it S works
while heating, R works for heating AND cooling.
M112
Emergency stop
M115
main parameters list (via USB)
M117 MESSAGE"xxxxx"
Display “xxxxxx” MESSAGE on LCD panel
M119
Show end stop status (via USB)
M140 S100
Set heated bed temp
M190 S100
Set heated bed temp and wait to reach it
M201 Xn Yn Zn En
Set max acceleration during print WARNING causes machine
restart (if used to change extruder accel, is meant to current
extruder, previously selected wit Tn)
M203 Xn Yn Zn En
Set maximum speed for selected axis
M206=& Xn Yn Zn
Set homing offset (default is zero)
M218 Tn Xn Yn
Sets nozzles offsets relative to extruder #1 Default distance (x,y)
both for A2 e A4 is : 0,24 (T1) 0,48(T2)
M300 Sn Pn
Play a sound at S frequency and P duration (milliseconds)
M301 Tn Pn In Dn
Sets extruder (Tn) PID.
M302 Sn
Sets minimum extrusion temperature
M303 Tn Cn Sn
PID auto tuning for extruder E at Temperature S, taking C trials.
