I decided to try to build a pen plotter. Using an Arduino with CNC Shield, 3D Printer spare parts from Amazon and some aluminum profiles.
I am not sure if I am happy with the result. As more often then not, I regret building yet another bulky thing which takes up a lot of space and isn't that useful. Need to find some place to put this thing. also, 2 of the "rails" on which the thing slides around arrived damaged. I ordered new ones, but they didn't arrive yet. The lines should get a bit more straight with the new rails.
I am thinking about what I could use this thing for. Maybe I could create some nice geometric patterns. I am not sure. Post a comment if you got any ideas for me.
The Arduino runs grbl. Here's the grbl Github Project:

I just love pen plotter's

Awesome, I got an old Roland pen plotter from a friend. It used an old serial or parallel connection and asks for a specific 9,7 and 37 volt PSU with three pins. Both the cables and the PSU are missing so I am thinking of turning the plotter into a Ramps-powered plotter with GRBL, USB and bluetooth. Very kinky project. The type of plotter is a Roland DXY-1100. At first I wanted to try and revive the machine as is, but it turns out it's so incredibly hard to get data through the original parts without an old computer and even salvaging such a power supply is basically undoable as they don't exist. I ordered a few buck converters on aliexpress now so that I can at least try and see if I can make the plotter turn on in it's original state. It has some built-in demo that you can run. If that runs I might try to get it working as-is, but at the same time I'm thinking, just to future-proof it, to maybe just take out all the electronics and put in a hidden Ramps board and run it that way. Would you know if GRBL support tool-changes? Since the plotter has a bay that supports up to 8 pens!

I don't think grbl supports tool-change out of the box. There's some discussion about this topic over here: github.com/cncjs/cncjs/issues/118 I looked up the Roland DXY-1100. It looks really neat. I love the way it is moving around; Speedy yet very accurately. Did you already figure out what kind of stepper motors it is using? If you are planning to use grbl in combination with A4988 driver chips you might be in for a surprise as the steppers might not of the bi-polar kind. You could, of course, use the drivers that are already in place. They'll hopefully support the step/dir interface.

What is processes of making bro

@rotorway133 7 лет назад

amazing ! What software are you using ?

@ElectronDust 7 лет назад

Hey Eric! Sorry for the late answer. I used a software called "UniversalGcodeSender" to produce the Gcode. On the Arduino I run grbl. The Gcode gets sent to the Arduino via the Serial Port!

Nicely done :)

@ElectronDust 7 лет назад

Thank you Chris. I think I want to try to use your handwriting software sometime soon. :)

Your machine is like what i had in mind before i settled on using the 3d printer. i would really like to be able to work with A4 paper or larger, perhaps core-xy would be better suited to the task. how did you go with the cd-rom drive style Z axis? i'm torn between solenoid and r/c servo for the pen/Z

@ElectronDust 7 лет назад

I was planning to get the thing to write on A4. But the placement of the CD Drive thing messed up my build. So the writable space is much smaller as a result. Which sucks. ^^ I thought about the servo/solenoid thing too. I didn't go with a solenoid because all the solenoids I own are too weak. And I decided against the Servo because it seems a bit annoying to get all the pens you want to use to fit the same "holder pipe" (since I just used a piece of aluminum pipe to hold the pen at first). Others made a build with a hole in a wooden block. But the point is, that all the pens need to fit nicely in there. Which I didn't like. So I tried the CD Drive thing.
