but wouldn't that reversal return SET MDI ACK\n\r instead of what i'm getting: \rSET MDI ACK\n ? it seems like i'm getting the ACK string *between* the cr and lf instead of having them reversed at the end. thanks! On Sat, Jun 12, 2010 at 10:29 PM, Eric H. Johnson wrote: > > It looks to me

I am basing what I said on looking at the code, I have not had a chance to try it. Are you seeing that through your code? Can you reproduce it through other means, such as directly through telnet? Regards, Eric but wouldn't that reversal return SET MDI ACK\n\r instead of what i'm getting: \rS

I don't see the same behavior over telnet, although I can't examine the raw strings that way and I'm not trying to store and work with the strings it's sending back like I am with my client. But given what I see over telnet it appears to work fine. I found a way to deal with it on my end. I test

Just a thought based on what happened to me in a similar context. Maybe due to buffering, the leading /r really belongs to the end of the preceeding response string? Only a thought. > -Original Message- > From: forget color [mailto:forgetco...@gmail.com] > Sent: den 13 juni 2010 18:09 >

[Emc-users] Etch CNC configuration

2010-06-13 Thread Todd Freeman
Hi, everyone. I have just built the epitome of awesome, which has sometimes been called, 'Etch CNC'. If for some strange reason you're not familiar, here is what I'm talking about http://axis.unpy.net/etchcnc . The problem is, I have no clue how to configure EMC to work with this homegrown driver.

[Emc-users] DXF to G-Code (CAM/Toolpath)

2010-06-13 Thread Shaffin Bhanji
Hello, Can someone recommend a good CAM/Toolpath software that natively runs on Linux/Ubuntu along side of EMC2. I am currently in the process of coverting my DXF file to generate the g-code but would like a graphical tool to help me achieve that. I am not sure what the defacto standard is. Than
