第二个问题:
具体内容是这样的
当我用串口向开发板发送Gcode如下:
T1 ;Switch to the 2nd extruder
G92 E0 ;zero the extruded length
G1 F200 E20 ;extrude 10mm of feed stock
G92 E0 ;zero the extruded length again
G1 F200 E-20
T0 ;Switch to the first extruder
G92 E0 ;zero the extruded length
G1 F200 E20 ;extrude 10mm of feed stock
G92 E0 ;zero the extruded length again
G1 F6000
然后我互换了一下T1 和T0
T0 ;Switch to the 2nd extruder
G92 E0 ;zero the extruded length
G1 F200 E20 ;extrude 10mm of feed stock
G92 E0 ;zero the extruded length again
G1 F200 E-20
T1 ;Switch to the first extruder
G92 E0 ;zero the extruded length
G1 F200 E20 ;extrude 10mm of feed stock
G92 E0 ;zero the extruded length again
G1 F6000
结果这次变成了只有右边的喷头挤出了料
然后将上面这段Gcode分两次发送。
T0 ;Switch to the 2nd extruder
G92 E0 ;zero the extruded length
G1 F200 E20 ;extrude 10mm of feed stock
G92 E0 ;zero the extruded length again
G1 F200 E-20
然后再发送
T1 ;Switch to the first extruder
G92 E0 ;zero the extruded length
G1 F200 E20 ;extrude 10mm of feed stock
G92 E0 ;zero the extruded length again
G1 F6000
都可以正常工作。
