Here is an updated installer that should resolve the issue:
Linda, you might want to try running this, and see if it can resolve the issue for you.
I now have what appears to be a fix for the issue, and I’ll hopefully be able to bundle that into an installer in the next few days.
Great news: I’m able to reproduce this here a file that @BamBam sent.
I have tested the link several times, and it seems to be valid.
You are describing what sounds like a different set of symptoms that has some overlap.
Can you please clearly state:
– Which OS and version
– Which exact machine you are using
– EBB firmware version
The issue that Linda was describing was with the EggBot, not AxiDraw. I’m not sure what you mean by “The one difference is that I use the eggbot extensions […]”
I’m not sure what file you are referring to being sent with the EggBot extensions — we haven’t posted any extensions in this thread, just a test file.
If you think that the issue you are seeing is file dependent — not occurring with the test file that we posted but occurring with one of your files — then please consider sending us a copy of the file to test.
Hmm. Everything you’ve described seems correct in the setup, and I haven’t found anything that points to what the problem might be. Let’s try a different approach.
First, please disconnect the EggBot from both power and USB, and then connect the USB cable (only) to it.
Here’s a very small test file:
Please open that in Inkscape, open Extensions > AxiDraw Control…, and select the first tab, called “Plot”, and then click Apply. Does that produce the same kind of communication error messages?
If you’d like to try this test with power, that’s fine too, but in the Timing tab of AxiDraw Control, change the top two numbers (writing/drawing and pen-up speeds) both to 1 (1% speed) first.
Well, there’s one that we’ve never come across before. Some searches show other cases of this issue on that platform.
There is some general advice about lxml installation here:
Depending on what’s available through your package manager, you might try installing python3-lxml or possibly libxml2-dev libxslt-dev python-dev, and see if any of those help.
Pretty rare in practice– just means that it isn’t installed correctly.
OS/version/architecture? And, is this macports?
In a new terminal, try
python3 -m pip list | grep lxml
from lxml import etree
Try opening a terminal, and in it launch python:
python3 -m pip install lxml
Is the EggBot connected directly to the computer by a USB cable, or is there any kind of hub, adapter, or interface between them?
All indications, thus far, are that the hardware is working correctly and that this sounds like some kind of software problem. I haven’t been able to reproduce it here.
Is your Windows installation in English, or some other language?
