立体散热器

Ok it is best to remove any fragile parts for this step.
You will need:
The 3D printer without the basin
Computer
Beamer
Dial gauge
Calipers
piece of paper
Machine clamp (something heavy)

First think you want to do once you have installed the software and firmware is check for life. Make it move just a little bit, check if the opto swtich works etc.
好的,在这一步你最好把周围所有的小零件都拿开
你需要准备:
不含树脂的3d打印机、电脑、投影机、千分表、卡尺、一张纸、机械夹(有些是很重的)
首先你要知道一旦安装好软件和固件,就不能大改了,只能微调,还要检查光电子端开关是不是好的等等
First step:
Put in the correct parameters in creation workshop. You will need to tell how many steps the stepper motor has to make in order to rotate 360 deg. If you are using micro stepping the general formula is (micro steps)x(stepper steps) in our case 32x200.
You will also need to put in the pitch of your lead screw. One rotation of the lead screw will move the sled 1 pitch up. 5mm in our case.
Now the program should know that our lead screw moves 5mm every 6400 steps, or 0.00078125mm per step.
Yeah uber accuracy, well not really you can not really count on a micro step to be absolute. Check out this Link to learn more about micro stepper behaviour.
第一步:
调整正确的机械系数。你需要设定进步电机在旋转一周内要走多少步。如果你想用小步伐,那一般的计算公式就是(小步数)X(进步电机步数),我们就是32X200。
你还需要设定导螺杆的节距。导螺杆转一圈它就移动一个节距,在我们这就是5mm的距离。
所以在我们这就是每6400步走5mm,或者每一步走0.00078125mm。
想要更准确,这是需要计算每一小步到底是多少。如果你想学习更多关于微进步电机的话,请看这个链接(楼主没给)

Now make it move. First start by giving it a command to move 1mm. Then one more mm. Small steps easy does it. Once you feel more confident move 10mm, all the take making sure you will not crash in to the ends of your lead screw.
Once you feel really confident set up a move of 50mm but this time be read to put your piece of paper in the gap of the Opto switch.
Press go and while your lead screw is moving put the paper in the Opto. Your lead screw should stop immediately. Repeat this process until you feel confident that it really works.
Once your happy it is time to verify the performance of your Z axis.
现在开始让它动起来。首先给它一个命令让它动1mm,然后再走几个。小步都是很容易做到的。如果你觉得走10mm都没有什么问题了,你就只需要注意不要走到导螺杆的顶端从而伤到它。
如果你觉得走50mm都不是问题,就可以开始用一张纸放在光电开关之间来试验了。按上开关,你的导螺杆就推着纸移动到光电部件上。这时,你的导螺杆就应该突然停掉。多重复几次,直到你认为它没有问题了。

Attach your micro gauge to a machine clamp, something heavy and immovable. Set the tip of the gauge on your sled.
Now move the sled 1mm towards the gauge. Verify with the gauge that when you give the command to move 1mm the sled really moves 1mm. repeat this measurement until you are confident that when you want your sled to move a specified distance, it really moves this distance. You can also verify larger distances using your callipers.
在机械夹上安装一个测微距计,在它的头上再安装一个滑车。现在向测压机移动滑车1mm。用测微距计来确认这个滑车真的按照命令移动了1mm。重复的测试,直到你觉得你可以控制滑车准确的移动,然后再用卡尺来测量大范围的距离是不是也是准确的。
As a result we measured a repeatability of about 0.01mm plus minus 0.003mm so I am confident to say that we have a Z axis accurate to 0.01mm
我们测量的结果是重复的误差在0.01+-0.003mm,所以我们的机械在Z轴上可以说是能精确到0.01mm。
Once you are happy you can put back together the entire printer.
Now it is time to set the height of the home position, this is also the start position for every print.
Lower the build platform down in to the basin, with your piece of printing paper between your build window and build platform.
Be very care full this is a very critical step.
Move the stage down while wiggling the paper until you feel the paper catches between the platform and the build window. Now this is your ideal home position.
Do not forget to make sure that every thing moves in the right direction.

游客,如果您要查看本帖隐藏内容请回复

Move the stage up until you can remove the basin.
Remove the basin and give the command for home. The stage should now move in the direction of the home position and stop the moment the finger is about half way in the Opto.
Once you are satisfied reinstall the basin and repeat the test.

If all worked out well you are now ready to print as soon as you provide some light shelter.

再向上移动这个橇板直到你能去掉树脂。去掉树脂后,在下命令让它回到原始位置。在移动的过程中,它会遇到弹片在半路上停下来。

你可以在加树脂,然后重复这个测试。
如果这些都没有什么问题,只要你能挡光的工具,就可以开始打印了。

Step 15: Software

第15步骤:软件
有一些很好的软件包。最后我们决定pacmanfan软件。他的名字是史提夫埃尔南德斯,他是一个很酷的家伙。
本帖隐藏的内容
在Arduino上安装他的固件
在视窗(windows)上安装他的软件
现在就可以开始搞了。


There are some pretty nice software packages out there. In the end we decided on Pacmanfan's software. His name is Steve Hernandez and he is a really cool guy.

Install his firmware on the arduino
And his software on your Windows
And you are now good to go.

Here you will find all the info you will need as well as the firmware and software:

Glue the walls of your basin on to the base plate with some silicone sealent.
It is important that you use the right type of sealent here, the one that is clear, colorless and used to build aquaria. Over the past few months we have tried a few different types, silicone = silicone right? Wrong! Different types of silicone have different compositions and we found that over time most silicones give under our abuse. They for some reason can not handle the mechanical stress. Or do not adhere to the aluminum properly, or the glass when exposed to our 3D resin.
Leave your walls and base plate dry for at least a day before you glue on the bottom.
The bottom is a bit of my special baby. I am not 100% happy with its performance yet but I'll dive in to that in the review of our machine.
