It's not a cape, but I just got a hold of a TinyG board. Not sure where to begin with it, but it is sort of on-topic ;-)
P.S. Advice for how to get started with TinyG is very welcome!!!!
I don´t have experience with one of the above cape, but I found this CNC Cape for LinuxCNC on Kickstarter which I think is quite interesting:
What do you think about it?
I have not tried any of these BBB Capes. I want to try a couple. I think I will start w/ this one: https://www.probotix.com/wiki/images/1/11/PBX-BB_rev5.2.pdf . I just cannot take the cost right now. I wanted to test it out and find out if I could use it.
This Cape looks and seems to be a bit professional. Do the persons at BeagleBoard.org support any of these Capes?
P.S. Please reply when you have time. I would like to know what you have found.
I've talked to several designers of digital fabrication machines (laser cutter, 3D printers, CNC mills, Pick-n-Place, etc) that are incorporating the BeagleBone Black (BBB) into their machines. It's price and capabilities are a good fit to replace dedicated laptop or desktop computer for running such devices. The BBB has the added advantage of its Programmable Real-time Units (PRUs): two 200MHz microcontrollers on the same die as the 1GHz ARM Cortex A8. This eliminates the need for a separate microcontroller board like an Arduino, ChipKit, LaunchPad, GertBoard, etc.
A prime example is MachineKit. A downloadable SD card image which runs LinuxCNC on the BBB. This enables makers to easily control a range of existing machines such as 3D printers and CNC mills. I noticed this list of BeagleBone capes on the excellent BeagleBone LinuxCNC blog:
An unofficial list of various 3D Printer, CNC, and motion control related capes I am aware of, along with their status. If you know of any I missed, or notice something wrong, please leave a note in the comments.
Contents:The boards are grouped by my personal experience with them. I have the first two (BeBoPr and K9) in-hand and have printed or moved motors with them. The next two (Replicape and Rosetta Bone) I have seen move motors via internet video. The remaining boards I have simply heard about, and are listed in the order I found out about them.
I'm curious - has anyone tried any of the above?
