View the command queue in the controller app.I added this extra feature to the queue preview that allows me to simulate common calibration errors. There is a page about this in the Polargraph wiki, but it’s quite hard to diagnose, and hard to explain in words. Preview cord offsetĪ commonly reported problem is that a drawing is short and fat, or tall and thin, or has a curved top or bottom, or it’s sides diverge. gco is not a standard enough file extension, so I’ll change it to.

Scripts that have funky stuff going on in their Z movement might need a bit of manual editing to work. Usually the first Z movement is to shift into travel mode, in order to safely get to the start point, and then the second Z movement is to drop the pen / tool. This is because dullbits has Z1.0 as it’s drawing position and Z0 for travel, whereas inkscape(‘s gcodetools) seems to have Z-0.125000 as it’s drawing position, and moved to Z5.0 for travel. Any position other than that second position is considered a travel (non-drawing_ position.

The very first Z axis change is ignored, and the second one is used henceforth as the “down” (drawing) position. The Z axis automatically makes a choice about when the pen is up or down. Now, it’s fairly simplistic, understands only G0 and G1 commands, and the Z-axis implementation is rudimentary, but it does mean that it can swallow the output of wonderful things like Dullbits’ beautiful Death-To-Sharpie sketch. g files too, so anything that emits g-code files is also now a contender. The controller has only been able to import SVG files, so a run through inkscape has always been the last step for most people. There’s a workflow that is sometimes fairly tortuous, even if it is logically straightforward.

Polargraph exemplar Kongorilla has made a number of not-so-subtle hints about the impediments he runs into in getting stuff prepared for drawing.

Last weekend was no different.ĭownload the result: Polargraph v1.2 code bundle, or read on… If you dare. However, whenever I actually get into coding in it again, I always regret my fear, because I get something really useful done, in a really short length of time. I remember it as being a twisted and unstructured wild-west kind of program. I am generally filled with forboding about adding features to the Polargraph Controller.
