Hey Riley,

Thanks for the response – I ran this gcode using CoolTerm on XP

http://dl.dropbox.com/u/9541708/hello_world_shape.txt
http://dl.dropbox.com/u/9541708/shape_line_80.jpg

..it stops at line number 80, every time then jerks over and the machine goes OC (wanting to travel x & y way more than it should)

It’s right before the arc in the h, TG actually prints this line.

Reported Line: {24} Arc specification error: G3X-1.
Full gcode line from file: G3 X-1.6859 Y0.1476 I-0.2729 J0.0036

Latest settings: http://dl.dropbox.com/u/9541708/tinyg_latest_settings.txt

It seems like XONXOFF is working ok here is the serial log

Note: I had to press reset on the TG to stop the ShapeOko from killing itself 🙂

Anyway, got the AVRISP – hopefully I can find some time to upgrade this weekend! Just thought I would provide some more info in the mean time.

Cheers

Mike

No idea if I am on the right track but this guys issue sounds very similar

http://bbs.homeshopmachinist.net/archive/index.php/t-44851.html

still reading through the thread but thought it may shed some light..

When sending the file via CoolTerm (using 1ms line delay), the progress jumps to 67% off the bat, then to 100% when the shapeoko has just finished drawing the circle.

Alden,

When using a 1ms line delay, I get strange results, normally where the file would quit before, the z axis now moves super slowmo for about 2 seconds (when we should be drawing the last 4) and then jerks over and draws the degree.

I attached a serial monitor to the port (http://www.serial-port-monitor.com/index.html), it looks like the all of the gcode is sent to the board right off the bat, not sure if this is normal?

Here is what the app logs under ‘Write Request’ as soon as the file is sent (ran twice): http://dl.dropbox.com/u/9541708/serial_output.txt

Is there anyway I can verify that the XON/XOFF is actually working or is it even necessary for a file this small?

I am running the FTDI driver version 2.8.14.0 – tried it on multiple machines as well, both XP x32.

Thanks for all the time!

Good deal, thanks for the info.

On another note, when sending a file via coolterm, my shapeoko seems to be stopping at the same point every time. Line #27 in gcode file below.

One thing I can think of is that the file transfer is ignoring the XONXOFF flow control setting..

I also ran the file using ril3y’s Swing app and actually got one line further, but it looks like there *could* be a serial communication issue looking at the console messages (http://dl.dropbox.com/u/9541708/tg_swing.jpg)

I tried different USB ports, I’m running it from a AAO netbook, not sure if that could be a problem?

Also, I’m supplying the 5+ from an Arduino, should that be sufficient?

Using a 24v supply, I have no heat sinks but I have a 12v fan directly over the board.

Sorry for all the newb questions but any ideas would be great!
