Is there a way to interface the MECHATROLINK-II protocol to Linuxcnc?
Appears to be a RS-485 based protocol from the research I could understand.

Overview

I accidently purchased the wrong servopacks from ebay so if they don't sale again on ebay, I will need to find a use for them.

it appears to be an open source protocol , so it should be possible yes
if or not it's totally suitable is of course another matter

Any good threads to reference about writing the drivers or is this something a person trained in programming may need to take on?

i'm trying to hack mectronlink interface, packet structure is known, but sync command not known yet. any process from you contact This email address is being protected from spambots. You need JavaScript enabled to view it.
i'm going to buy a NT110 mlink-pci interface card to help hacking this closed source protocol.

slightly off topic but mechatronik III which is ethernet based up to 100mb/s , & ii which is rs485 up to 10mb/s
some additional reading :

I asked about Mechatrolink I a while back. All the info is there for Mechatrolink members. You will either have to build the hardware or use a card from Yaskawa certified hardware. Let me know if you make any headway on this or have a programmer interesting in making the driver.

just got it running. the interface seems to be working ok so far using a cannibalized ethernet transformer for rs-485 isolation and off-the-shelf USB cables/connectors. the controller is implemented in a FPGA on one of my SSCNET cards. will probably make Mechatrolink II version soon...
