Question

我写了一个小型的python Gcode后处理器，为3D打印添加了一些内容。最初的问题是，每次更换工具头时，我都需要3D打印机生成清除块。如果没有更换该层的工具，则仍需要建立吹扫模块，并在层的末尾使用活动的任何工具来结束该层的末端（因此，塔筒继续增加高度而不会丢失层）。

很抱歉，这很难想象，我添加了一些照片，以减少想象力：

问题在于，当仅打印一种颜色时，似乎只能建立一塔。这可以通过缺少一层来看出，然后一个塔比另一个塔短，因为最后50层都是蓝色。谁能阐明为什么会这样？

更新：我注意到代码在说，尽管修改后的Gcode中没有左右两层，但它已将左右两层的塔放下了。这意味着它必须使用rightwriter函数放下右塔，然后使用leftwriter函数覆盖它。我不明白为什么会这样，我在调用写函数之间调用了nextzvalue函数来避免这种情况。我的解决方法是让它打印出包含两个带有独立功能的塔式Gcode的代码，但id想知道为什么会这样。

代码：

def main():
    file = open("example.gcode","r")
    lines = file.readlines()
    file.close

    oldzline = 320
    tower1count = 0
    tower2count = 0
    layercount = 0
    linecounter = 0
    numberoflayers = layercounter(lines)
    toollist=[]

    while layercount < numberoflayers:
        tower1count=0
        tower2count=0
        nextzline = nextzvalue(lines,oldzline) 
        print("layer count: ",layercount)
        for line in lines:
            linecounter +=1
            if linecounter > oldzline and linecounter < nextzline:
                if line.find("TOOL CHANGE") != -1:
                    if lines[linecounter+3].find("LAYER CHANGE") == -1:
                        if tower1count==0:
                            tower1count+=1
                            print("tower1 count 1: ",tower1count)
                            rightwriter(linecounter,lines)
                        elif tower1count==1:
                            tower2count+=1
                            print("tower2 count 1: ",tower2count)
                            if tower2count!= 2:
                                leftwriter(linecounter,lines)




        if tower1count == 0 and tower2count == 0:
            nextzline = nextzvalue(lines,oldzline)
            tower2count+=1
            tower1count+=1
            print("tower1 count 2: ",tower1count)
            print("tower2 count 2: ",tower2count)
            rightwriter(nextzline-4,lines) <<<<<<right writer code being overwritten.
            nextzline = nextzvalue(lines,oldzline)<<<<< I believe this bit is not working correctly.
            leftwriter(nextzline-4,lines) <<<< causing this to overwrite the code added by the rightwriter function. 

        elif tower1count == 0:
            nextzline = nextzvalue(lines,oldzline)
            tower1count+=1
            print("tower1 count 3: ",tower1count)
            rightwriter(nextzline-4,lines)

        elif tower2count == 0:
            nextzline = nextzvalue(lines,oldzline)
            tower2count+=1
            print("tower2 count 3: ",tower2count)
            leftwriter(nextzline-4,lines)                       
        print("tower 1: ",tower1count)
        print("tower 2: ",tower2count)
        #if layercount == 121:
            #print("sleepy time")
            #time.sleep(100)
        oldzline = nextzline
        linecounter = 0
        layercount+=1

def nextzvalue(lines,oldzvalue): # finds the nex Z value i.e. the end  of the current layer/beggining of next.
    linecount = 0
    for line in lines:
        linecount+=1
        if linecount > oldzvalue:
            if line.find("G1") != -1:
                if line.find("Z") !=-1:
                    return(linecount)

def layercounter(lines): #counts the number of layers and returns them as a number
    linecount=0
    layercount=0
    for line in lines:
        linecount+=1
        if line.find("G1") !=-1and line.find("Z") != -1:
            layercount+=1
    return(layercount)

def leftwriter(linecount,lines):
    linecount = linecount+1
    #print("making a T1 layer")
    lines[linecount] = "some gcode to draw a layer of left tower here"
    with open('Example.gcode','w') as file:
         file.writelines(lines)

def rightwriter(linecount,lines):
    linecount = linecount+1
    #print("making a T2 layer")
    lines[linecount] ="some gcode to draw a layer of right tower here"
    with open('Example.gcode','w') as file:
         file.writelines(lines)
