TinyG Raspberry Pi configuration

Connection and system

• $defa=1 reset to factory defaults
• $ec=1 expand LF to CRLF on TX
• $tv=1 text verbosity = verbose
• $ee=1 echo on
• $1pm=1 power management motor 1
• $2pm=1 power management motor 2
• $3pm=1 power management motor 3
• $4pm=1 power management motor 4

Y-axis (gantry) on Motor 2

• $ysn=3 y minimum limit+homing
• $ysv=3000 y search velocity
• $yfr=3000 y feed rate maximum
• $yvm=40000 y maximum velocity (mm/min)
• $ytm=400 y travel maximum for 625mm gantry
• $ylv=1000 y latch velocity
• $yjm=10000000000 y jerk maximum controls acceleration during unconstrained motion
• $yjh=40000000000 y jerk homing maximum. Too much and motor slips. Too little and head crashes too hard
• $2tr=30 motor 2 travel per revolution for GT2 15-tooth pulley

Z-axis (tray feeder) on Motor 3

• $zsn=3 z minimum limit+homing
