Roland DXY-100R "Expandable Intelligent X-Y Plotter" is a new one to me:

Can't find the manual anywhere. What does "expandable" mean here?

#penPlotter updates:
The DMP40 in the foreground has its belt sensor working again, but needs idler wheels. The ID is _slightly_ smaller than the printed ones I have, so that’ll need a new stl drawn up.
The larger DMP60 is approaching working. The idlers that a fellow mastodonian printed for me were starting to slip. Someone at the shop at my job printed me a pair and they’re working _so far_ on A size paper.
A few oddities:
I had to destroy one of the clips that held the idler wheels in place, so right now both are just slipped on to their axles and not held at all. Somehow that seems to be OK… they’re not regular e-clips; there’s no groove on the axle, just a pressure fit. Modifying stock e-clips to fit has failed so far.
One of the idler wheels was _slightly_ smaller than the other, and the printed rubber tire was slipping off the wheel. A layer of electrical tape seemed to help. Interesting that the force was able to pull the tire off the wheel but not the wheel off the axle

It’s insane how well these things worked. An E size (or A0 for those of you in the first world) sheet of paper is f$&king huge, and these things would throw them around with great speed and accuracy.

Sold a #penplotter drawing so I put a new one up in the store!

I drew Facts and Figures #5 back in 2023.

All of the graphs are randomly generated and placed!

Soo… I bought another plotter. It was close by, dirt cheap, and came with some other goodies I’ll share later.
On power up, the pen carriage homes all the way to the right, but never stops. I don’t see any limit switches, and it goes on for much longer than it would take to do the entire travel.
There’s this flywheel looking thing labeled Ferrofluidics corp, which looks suspiciously fancy (it’s got a serial number).
The stepper motor has 8 wires.
So.. what gives? Anyone know how a mechanism like this would have homed itself, or what that mysterious blue object is?
It’s an intriguing mystery… plus I’d love to actually get this working; it’s a nice medium size between my other two plotters.

@beardicus found your OpenSCAD model after making my one eheh thanks for sharing, it's a great resource! #3dprinting #penplotter

This is a hack for using BIC ballpoints pens on vintage pen plotters. Note that this model is highly experimental, more experimentation is need (an #OpenSCAD file is available). #3dprinting #penplotter

August '25 print set

This month I grounded myself with a simple graphic dash pattern that evolves through the print set as scale changes and layers get added.

Uniball Signo .38 pens and paint on 5"x7" Arches watercolor

The ink is rather old, a few decades, although I like the final greenish general tone (should be black).

And still struggling to get faster speeds on the machine.

Ink on A3 paper.

Found your code @notmycommit :D

My Roland GRX-400 is very slow using Chiplotle, going to test your code for speeding it up, I hope #penplotter

The original circular HP pen plotter organizer boxes have foam dividers for the pens. Now the foam is turning to goo. I created a new insert to replace the foam and hold 40 pen plotter pens. Should fit the short or tall circular pen box.

I've been trying to get this style of plotter image to work since before 2012: representing brightness with isolines of a function with higher gradients where the image should be darker so the lines are closer

After getting something close but not very good a couple of months ago in the last two days I saw a post on Reddit with a new technique to try (fast marching method) and yesterday I got a process working in Python. Over 13 years and it finally took a day

Maps look surprisingly good in silver! h/t to @doersino for his osm2svg tool https://ghpages.noahdoersing.com/osm2svg4art/ and thanks to Dirt Alley Design for organizing the plot party on Instagram.

Trying to do my first-ever #PlotParty ! Today's theme is SILVER, and my piece is partway there, but there's some new workflow stuff I'm figuring out.

So, here are a couple of my previous silver plots to start with :D
