Run Test #6

How well can others run the following lines without missing any lines and usb keeping up? The following is a bunch of ~0.1 mm lines for part of a small wooden gear. When I run it with my modified version of Grbl doing some extra handshaking I get delays. Arduino runs the lines as fast as it gets them and is waiting for usb to feed each line. Maybe ~0.1mm moves are too small? Maybe I need to do bigger buffers/possible SD card.

Think I found my problem with my usb being slow…..in python
I had my python usb timeout set = 1, I changed it to 0.1
Units I believe are seconds.
The following works much faster :-)

MyUSB = serial.Serial(usbport, 115200, timeout=0.1)

Highlander,
I’m really excited about your additions to Simen’s code. Could you put that python script somewhere for download. Once I get It i’m going to try installing your fork and see what happens.

I plan to get the python code posted at the following location this weekend:
http://github.com/Highlander01/Highlander01HMI

I posted a screen shot there previously/the git software took me a little effort to post with. If people like it I will see if Simen Grbl wants it located on his git location. Would be cool if others with some python and opengl experience could help with some fine tuning. ex. faster refresh/redraw of gcode graphics. linuxCNC does it pretty fast some how.

Took a little bit of learning but I figured out how to post to git. I posted my python code and a slightly modified version of Simen Grbl code at:

http://github.com/Highlander01/Highlander01HMI

I have strayed slightly but would like to join back to a version with Simen some day. For now I hacking and playing.

My first finished basic version is now posted: http://github.com/Highlander01/Highlander01HMI

Updated version of my Python HMI/GUI and slightly modified version of Simen Grbl is now posted. I have now test ran my gear tooth gcode file with 3200 lines and have had no hang ups etc. Terminal screen shot showing usb handshaking is posted also.

I think I am going to now do my first cutting project and build a wood clock!

(later on I plan to go back and do some OpenGL graphics enhancements.)

Looks great Highlander! I’m planning to mount a simple cutting head on my machine in the next few days, after that’s complete I’ll post a video of the mill cutting with GRBL + HIGHLANDER front end. Great work!

This is still a problem for low baud rates, but not much to do about that I think. I have reduced serial output to an absolute minimum in the new acceleration-branch that I am preparing to release.
