I really love it when people are able to repurpose/recycle parts and make them do awesome things like this!

Began learning about arduino last June but only recently started looking into stepper motors. I came across some videos of XY plotters but thought I'd try using a marker pen instead to draw small circuits. This way I'll reuse old dvd/cd drives, learn cnc and build something useful. Your work will be my main guide and I just wanted to leave a comment because I found your pen holding mechanism really, really clever. Glueing the top ring to act against the servo horn is so simple but effective. Thank you for sharing

Over simplicity,owesome,you have just opened a new train of thought,appreciated

Well done Dirk! You are a (rare) example of a REAL engineer. Merging every aspect of engineering to achieve a goal: electrical, mechanical, software, chemistry! I love it. No sure what you are doing for etching but I found very small quantities of HCL + H2O2 is very effective, inexpensive and clean.

amazing design, its simple but functional and the best part its the lack of Dremel tool noise, congrats

Dirk that was simply amazing man. You my friend will survive the fall of man, zombie apocalypse. Very inspirational work, wished people post more work like this. Thanks for sharing.

The controller is an Arduino Mega. The software on the controller is based on rsteppercontroller. The software to make the PCB layout is Eagle. It generates HPGL which is then converted to g-code by hp2xx. The software to sent the g-code to the Arduino is ardGcodeWriter, a python utility.

No bushings, the rails are 4mm brass tubes, the sled is 6/4mm CFK tube, some silicone based lubricant keeps it gliding softly.

Hi friend, in the files you shared in version 4, are different materials used from version 3? Or are other materials added? Thanks

I have made PCBs with SOT23 and 0805 SMD parts on them, but a 8mil track is beyond the capability of this unit. The pens I use have a 0.4mm (15mil) line width and require at least 4mil clearance. The limitation is imposed by the 3.6deg/step motors and the pen holder. With better parts at hand, and a better pen I guess it could be possible.

hello, in the manufacture of the PCB the pen goes from the side of the track, how do I make the pen paint on top of the track. thank you

The use of a servo is brilliant for the Z axis, you're full of great ideas!

You need to import the entire project from the uCNC_controller directory, the Arduino IDE should open several files. Then you need to read through the uCNC_controller.ino file and make some small changes that describe your setup. But that is mostly it - if you run into any issues, I'll be happy to help.

How does the software know how many steps per unit of distance? If I use a different motor, how to do I tell it there are 0.8 steps per degree, or that 360 degrees of rotation translates to 1.3cm of travel? Is it the G-code generator or the Arduino sketch which translates distance units into motor steps?

@dherrendoerfer

10 жыл бұрын

No, you need to make a small change in the firmware for that. The firmware uses steps per millimeter as a settting for each axis, so you can use three different steppers, or have a different drive setup per axis. The same is also true for the maximum speeds per stepper.

what software did you use? also what controller?

The control software moves the pen into the lowest left corner of the build platform. Since the nylon will eventually slip on the drive shaft it simply does this by force. It then resets it's position to 0.0 and waits for commands. This feature can be enabled in the source code.

Vinicius Rangel Follow the link in the description to my github repo. There you can find a number of designs and firmwares, version 4 (v4) has drivers and support for bipolar steppers.

For the holder of a pen... Roll the pen in paper, and hot glue the paper into a solid tube. A chick layer of hot glue all around, to make a "cocoon". To reduce pen wobble even further - The paper can be bent closer to the tip of the pen. It keeps the pen from falling out, downward, as well. The wiggle is minimal, as the paper tube is fitted on to the pen, and the hot glue holds it in place. The contraption can be hot-glued to any carrier plate... generous amounts of hot glue will form a solid block of stiff plastic. It's almost like like 3D printing.. This looks childish, but it works. And you can make a new tube for any size and diameter of a pen, literally, within minutes. No drilling, no nothing - hot glue and a peace of paper (preferably slippery paper of lower friction).

Nice working prototype. Thanks for sharing. Just an idea, how about using the drying time to drill the holes in the pads. Should minimize any damage to the pads due to mechanical adhesion of the copper prior to the etching process while making for an even faster turn around time. Do it manually or automatically by replacing the ink pen with a Dremel tool or equivalent using the same CNC, eliminating any registration problems. Any problems with debris or anything else should be an easy engineering fix. Just a thought.

Hello, thanks ! No, linear bearing do improve the drag factor, 8mm ones are quite big an heavy though, the setup with the string is copied from several printer and plotter designs from the late 80s to mid 90s, this design was quite common. Cheers, Dirk
