v1.5.6 电路板

警告:适用于v1.5.6的UltimakerPCB板,不适合更早的版本。另外,由于用的很少,所以像v1.5.5这个中间版本没有发布。

该PCB板与包括RAMPS在内的其他Pololu-based electronics类似,但它支持5个步进电机(X,Y,Z轴3个,挤出机1个,另1个可用作其他功能)。你也可以按照自己的需要,多增加些步进电机驱动板。它的运行电压在12V以上,可以在一个MOSFET管输出90W的功率,使步进电机在更大的转矩、更高的转速。该板也用在Protospace的Mantis-30雕刻机,以及各种各样的Mendel 3D打印机上。

特色

  • 基于Arduino Mega
  • 电机采用四路JST插头连接.
  • 适合Ultimaker's UltiStepper Driver
  • 兼容Pololu stepper driver boards
  • 控制电机增至5个(X,Y,Z轴3个,挤出机1个,另1个可选,添加一个步进电子驱动就可使用)
  • 改变跳线可以配置步长
  • 三个55Amp MOSFET管(带有LED指示灯。实际输出能力受PCB板和接头限制)
  • 所有的引脚都被引出,用于今后的扩展
  • 15V到19V的工作电压
  • 三路热电偶(或热敏电阻)输入。推荐100K的热敏电阻。
  • 一个外接LCD面板的IDC插头(movie here
  • 一个外接SD卡模块的插头。
  • 一个用于开关板子的拨动开关
  • 易于热电偶的接线
  • 有一个12V的稳压芯片,用来给风扇供电
  • 用于LED或其他照明设备的PWM输出口
  • LCD背景灯可以由软件调整
  • 一些用于蓝牙模块和以太网模块的IO口
  • 实验性的安装了些伺服输出口。由于这些伺服输出头的I/O口没有PWM功能,所以需要用中断或是软件来生成。

新版特色

  • 兼容UltiController

- The Arduino Mega 2560 can be self-powered from the DC-jack. - Jumper added for controlling autonomous power setting - 100 uF connection to Vcc2 - High-current track from DC jack and ON/OFF switch moved slightly - Better suiting the footprint of the rocker switch

设计PCB后,Marlin固件的兼容性不受影响。

第一步 焊接arduino那面的插针

这实际上是1.5.3版的说明

我们从背面开始,这边没有任何文字,只有DIP插针。
这些插针供接下来插入arduino板。注意DIP插针的个数要适合arduino板。

要让PCB上的DIP插针恰好适合arduino的最好办法是先把插针插在arduino的DIP插槽内,然后将带DIP插针的arduino插入PCB版。
这样PCB上焊的DIP插针就完全适合arduino板了。
把PCB板正面露出的插针引脚焊上,然后再取下arduino板。

拿下arduino板时要小心,要左右交替着向上抬起PCB。如果你单从一侧用力,会把插针弄弯,见下图:

要像这样做:

接下来放置印刷层的元件(带有白字的那面),最好从最小(或最大)的元件开始焊接。

拓展模块

Ultimaker TC 热电偶模块

DIY的3D打印机玩的多了,你就会发现挤出头温度测量精度直接影响打印效果。热电偶比热敏电阻更稳定、更精确,但是需要更高的成本。你需要一个特别的芯片来放大测量到的信号,Ultimaker TC小板上采用了这种芯片(AD597)。

在v1.5.4上增加该模块

这里是R23、R21、R4的所在位置

注意:如果想用热电偶来代替热敏电阻,就不要安装R23电阻,这很重要。只有用热敏电阻测温度时才用R23电阻!如果已经焊上了,就想办法把它摘掉。一旦你用热电偶,就不可能在用热敏电阻了。同样,如果你把另外两个输入端(Tem2或Temp3)也换成热电偶了,就把相应的电阻R21或R4也摘除(就在R23的旁边)。

约定,第一个挤出头用Temp1.假如你有两个挤出头,第二个就是Temp2.热床用Temp3.
Note: follow this specific order:

  1. Connect the 5V to the thermocouple board.
  2. Power up the Arduino by connecting it to the USB port of your computer.
  3. Connect the ground (- or GND) to the thermocouple board. The blue LED should light up on the little thermocouple board.
  4. If you already have the software installed: Open up ReplicatorG, look at what reading you get in the control panel.
  5. Connect the signal wire (Sig). See if the value changes. If it does not, you have the wires connected incorrectly or the firmware tries to read a different input.

The thermocouple board has three connections to the Ultimaker PCB, signal, power (+ or 5V) and ground (- or GND). The preferred wire colors are brown or any other color, red and black, respectively.

The Ultimaker thermocouples have Yellow and Red wires. The yellow one goes into the + of the little thermocouple sensor board, the red thermocouple wire goes into - of the thermocouple board (on the TWO wire screw terminal, not the 3 wire terminal). Cut the thermocouple wire to exactly 15 centimeters, this is optimal because the wire will pick up less interference (the shorter the better) but not be too short (which is a problem for the sensor chip, it thinks the inputs are shorted out).

不工作怎么办

  1. 确信你正在运行Ultimaker固件
  2. 加热热电偶,检测温度为0度以下。说明你把热电偶的连线接反了。
  3. 温度值不对:检查那三个电阻移除没(R23、R21、R4)。
  4. 温度值是499.9度:检查连线是否正确,接线是否牢固。
  5. 温度值波动太大?检查C1、C9、C10安装没有。
  6. The thermocouple is nothing more that two wires of a specific metal that are connected together at one end. This is the measurement end. You can make your own by fusing the end together (do not use solder, it will melt at normal operating temperatures of the extruder. The original thermocouple supplied with Ultimakers has a standardized thermal resistance to the aluminium heater block, so this will give the most reliable measurement.
  7. 用自己的固件?Ultimaker热电偶模块中使用的AD597与AD595完全兼容。确保AD595_THERMOCOUPLE被定义了,关闭对热敏电阻的测量。
  8. 如果你调换了黑线与信号线,LED灯可能也亮,但是这并不表明你连线正确。错误的接线可能会损坏你的热电偶模块。
  9. 热电偶一直显示室内温度,当用打火机加热时也不改变:AD597芯片当前处于自测模式。如果热电偶的+ -输入端电阻很低,它不会显示热电偶温度,而是显示芯片本身的温度。把温热的手指按在芯片上检查,如果值迅速改变,说明确实是这个原因。用一个接线端延长热电偶的接线,或是在接线端加焊个电阻。

修改

  • There was a tiny mistake in the silkscreen, the 36 pin header of the Arduino has 5V on pins 1 and 2 and GND on pins 35 and 36. The mistake is that the silkscreen has a label for Arduino digital pin 22 and 23 one row too high (so besides the 5V outputs). Since version 1.5.4 this is fixed.
  • 1.5.4 can measure if the power it turned on and which voltage power supply was connected.
