3d Printing / CR-10 open source
Last post by Dave -
The CR-10 is now OSHWA certified and the source code has been published on Github. :D

This is mainly down to the open source advocacy, in China, of Naomi Wu. (@realsexycyborg)

She has released a video on it.

While the CR10 is an older printer it is important that the source code is available for several reasons, the main one being that it is part of the GPL terms. Another reason is that it allows for much easier modding of the printers which should allow them to be upgraded into the future.

I have removed the chat box for now. It's not being used and slows down the server somewhat.

At $6499 USD this isn't for the hobbyist... :o

MakerBot Method - Professional 3D Printer - Rapid Prototyping 3D Printing

https://youtu.be/wsVJb0ijNn0

It is a professional, enclosed 3D printer and is being targeted as an alternative to industrial systems. It is also allegedly up to 2 times faster than other systems.

It is still an FDM system and appears to use enclosed spools which also appear to be proprietary as they are calling them 'smart spools'.It also appears to be using proprietary software.
It has 21 sensors on board including filament sensors and enclosure sensors.

3d Printing / The Anet A8 has been updated...
Last post by Dave -
So, it looks like anet finally updated the venerable A8.

According to Gearbest the specs are:


Quote
• DIY, modular dual version, customers can choose according to their needs
• Aluminum frame, Y-axis double-axis, Z-axis double-threaded rod, stable structure, good transmission precision and high printing precision
• The molding size is 300*300*350mm, which solves the painful point of high price on the market
• X-axis and Y-axis belt tightness can be adjusted freely, effectively preventing the belt from loosening and jumping
• Automatic feeding and unloading function, easy to solve with feeding and refueling        
• Magnetic movable screen, breaking through the ergonomic design screen for easy operation
• Patent extrusion mechanism, smooth discharge without plugging, short-term feeding, improve the effect of printing soft consumables
• Aluminum substrate hot bed and glass panel, the printing is flat and not warped, easy to take out the model
• The latest upgraded motherboard, over-current protection, short-circuit protection circuit design, configuration of smaller current, safe and reliable

You can find all the details at https://www.gearbest.com/3d-printers-3d-printer-kits/pp_009449214306.html?wid=1433363 for around €325

So far I can only find it on Gearbest and a small spec sheet on 3dprinting.com.

Ok. Got all the cells out. It was 3 sets of 2 for 11.1v.

One set are registering 0v so I'm assuming that those cells are dead.

This is a diagram of the pack

3 negative terminals, 1 for each set of 2. Then there is a single positive connection.

There is also a single thermocouple for safety on a single cell.
