I'm trying to use sagetex to plot 3d graphics in LaTeX. I can get the basic plot to work but there isn't enough detail. When I try to create more points in my plot I get the message: "! Unable to read an entire line---bufsize=200000. Please increase buf_size in texmf.cnf.". I found a texmf.cnf file on my system, made a copy of it with a modification of the bufsize to read "buf_size = 1000000" and uploaded it to my Cocalc project. Following this FAQ page I created ~/texmf/tex/latex/local and moved my texmf.cnf file there, When that didn't work, I tried texhash ~/texmf as suggested. However, I still get the message "! Unable to read an entire line---bufsize=200000. Please increase buf_size in texmf.cnf."

How do I change the bufsize on Cocalc? Are there any guidelines on a reasonable buf_size value to increase to?

Please share code that others can use to reproduce the problem: minimal .tex document with the minimal plot that illustrates this.

This question seems very specific of Cocalc's TeX setup, therefore better addresed to Cocalc's support team...

I've emailed Cocalc support for help. Should I delete this question?
