Thanks for exploring unusual ways to use things, it gives inspiration to engineers, makers and hackers !

[@HomoFaciens]

[@gregryan7761]

Simply amazing, reminds me of my first printer. I had a C64 printing graphics to a 9 pin dot matrix printer. It literally took an hour to print out a turtle graphic 9x10" on a single sheet of paper in low resolution. I thought back then that instead of using the God aweful slow serial bus on the Commodore 64 that they could have interfaced a printer thought the User's interface, being its an 8 bit bus. Curious to me why that bus was ignored by developers.

Hi Mr Norbert , Using the same mechanism (printer). Can you replace the dc motor and replace it with a Stepper motor? I want to change DC motor to Stepper Motor. Thank you very much. Best Regards. Necmettin.

[@HomoFaciens]

If you rewrite the software (which is very experimental, but open source) you can also use two stepper motors.

[@vthrash7832]

Thanks so much for teaching this stuff. Mechathronic is a very interesating thing to study!! I Always wanted to build my own cnc, i even scrap some steppers from copy machines, but i didn't found a realiable way to build linear guides.

[@TheKitMurkit]

You show great ideas in your videos! These ideas came to me and of course to many others, but I lack knowledge to bring them to life.

[@TheKitMurkit]

And the only obstacle on the way of opensource 2d paper printer\plotter is the lack of cheap and open printing head with good parameters.

[@HomoFaciens]

Yes, some more types of easy to handle and broadly available print heads would be nice.

[@HalfLife2Beta]

Very interesting video, how did you get the wiring of the linear optical sensor for the printer scavenged part ? I got a 6-pin sensor unfortunately i cannot solder cables to the pins because they put anti-soldering compound on the board, I now have the choice between trying to use the 12-pins ribbon cables or unsolder the component, what do you recommend? Would I be able to use a bought optical sensor and how would I choose one for this linear strip ? Thanks in advance for all these questions and keep up the great content.

[@HomoFaciens]

I would try to grind the anti soldering compund from the pins. My second choice would be to use the ribbon cable. While trying to unsolder one of those sensors I destroyed the device. If a bought sensor works with the stripe and what type to use? You must try out to find the answer. Since you won't get the specifications of the sensor stripe, it's gambling...

[@HalfLife2Beta]

Hello I just wanted to know how to replace the DC motor to a stepper motor in a printhead assembly without removing the belt, how would one proceed ? Thanks in advance

[@ecan]

Hi; I'm interested in how you arranged the ink reservoir; could you explain it, please? I cannot find any info regarding it on the project page...

[@jorgenlannock]

it is very interesting to see your videos and the way you use scrap material that usually got thrown away in this society. great videos :-). Friendly greetings, Jörgen

[@rapsod1911]

Line strip in printer is used for speed control. I always thought that is used for position but when I disconnect sensor carriage start to move very fast. I try to measure frequency on drum line strip and it was 20khz.

[@HomoFaciens]

When removing the sensor stripe, no position pulses are received, thus the microcontroller assumes the motor doesn't move, which is why it raises power to maximum and that's why the carriage starts moving with full speed.

[@PowerSports]

How hard would it be to optimize the printing software, so the carriage doesn't have to move all the way to each side, every time?

[@HomoFaciens]

Not too hard (if you can do coding).

[@Alley00Cat]

Awesome video, you are very good at explaining complex topics. Do you have any instructional material on combining say a printer with a scanner to use for laser cutting or as a base for a router?

[@HomoFaciens]

Lasers are dangerous tools, thus nothing for people asking how to build laser cutters ;-) This printer is part of a series of CNC machines I am creating for this year's HackadayPrize: hackaday.io/project/10299-self-replicating-cnc-for-194-or-more-countries The goal is to build a CNC machine using low tech materials. Stay tuned to see what machines the future development will bring to live....

[@HalfLife2Beta]

I'm asking a lot of questions here but how would one proceed to replace the DC motor with a stepper one without dismantling the belt ? I cannot seem to keep the plastic gear but remove the spindle out of it without moving the belt :/

[@HalfLife2Beta]

I'm talking about the printhead asesmbly btw

[@aburimor]

Regarding the 8:22 part - this is awesome and simple, but I don't understand how it works. The wire is sticking from hole in reservoir full of paint? How the ink doesn't leak from the hole? What is the actual printing action? At first I thought like the wire sticks out of the reservoir and retracts back, bringing drop of into on the paper, but it doesn't seem to work this way. I looked at the pictures on your blog, those are big and detailed, but I can't say I understood it any better.

[@HomoFaciens]

The viscosity of the color is pasty so that is doesn't leak. It's house paint (don't know the exact term, it's "Fassadenfarbe" in German). In rest position, the tip of the wire is flushing with the bottom of the ground plate. When the relay gets energized, the wire is moving down, touching the paper and so trensferring the ink. It's not shooting drops like an inkjet.

[@aburimor]

Oh I see, thanks. I have some other questions, if you don't mind ;-) Looking at the picture here www.homofaciens.de/bilder/technik/cnc_v3_1_009_1920x1080.jpg The plastic parts inside the reservoir (visible at bottom left picture) are just to keep position of the needle wire? The needle, slightly sticking out of the reservoir at upper right picture is at rest position? By the way, great channel with a lot of ideas, I subscribed.

[@HomoFaciens]

Yes, the plastic part inside the reservoir keeps the needle in place. No, that's not the rest position (it's flushing with the bottom of the plate). I wanted to make the tip of the needle visible on the photo, thus I used a piece of cardboard at the relay to fix it in that position.

[@aburimor]

Thank you much for your explanation, now it's clear to me. The principle is very simple, but apparently effective. Thumbs up for the idea.

[@NivagSwerdna]

What about inertia? Would it make sense to slow down as the set point is reached?

[@HomoFaciens]

There is a proportional control loop implemented in the Arduino software, but I did (almost) no optimization. It was a quick build.

[@NivagSwerdna]

Really cool video. Thanks. I must have a go with something... just have to walk the streets looking for old printers now!

[@martysworkshop208]

A really good and clear video, I like.

[@georgm9951]

really like your videos ☺ (especially the CNC ones). funny thing about this one is that, with this paint delivering method, you basically created the prototype of an automated tattooing machine 😉.

[@HomoFaciens]

...must find a way to wrap it around an arm to start tattooing 😉.

[@Rouverius]

5:54 Combining ideas, could an IR sensor be used with a encoder made if various IR filter films? Similar to the resistor array, each position would have a measurable opacity to IR light. This should in theory create identifiable voltage values from the detector. What do you think?

[@HomoFaciens]

The problem is, that you don't get a clean transition from one opacity to another as you get with the resistors (infinite or fixed resistance). You need two IR sensors as demonstrated in my video about rotary encoders: kzbin.info/www/bejne/jnq4o6GIbcd_d6s

[@Rouverius]

HomoFaciens Thanks. I was assuming that there would a thin metal frame to support the filters as a disk, the frame itself might provide some transition. Of course, if it could be easily done by simply adding another sensor then that seems like the most pragmatic solution. Thanks again.

[@shawnalfaro6943]

ok i have a question er, rather a few of them. I have an old large format plotter, the motors are rotary encoded DC motors, the various sensors are linear encoders. The original computer was old, 1993, didnt have the patience to try to get it to interface with my iMac. So i got an arduino. I know that the motors will require H Bridges, but can it effectively run 2 motors, and 3 linear encoders to use as a plotter again? the pen holder is a relay engaged device with a small encoder on one end. Can the arduino do all of this?

[@HomoFaciens]

How many motors an Arduino can control depends on how many pulses per second are coming in and so on your hardware setup (motor speed, pulses per revolution). I recommend using an Arduino having at least 4 hardware interrupts to get the maximum reading speed. The UNO only has two of them.

[@MrRevolverkiller]

HomoFaciens will a Due work?

[@HomoFaciens]

This page lists the numbers of hardware interrupts the Arduinos have built in: www.arduino.cc/reference/en/language/functions/external-interrupts/attachinterrupt/ As said before, if they are fast enough depends on your plotter hardware. You must try to find that out...

[@SiriusFuenmayor]

I read below that the printer resolution is 1 mm. Is there a way to improve this resolution by rewriting the code? maybe using interpolation

[@HomoFaciens]

Yes, with some software optimization, you could get better results, but why? It's just a demonstration of how things work.

[@SiriusFuenmayor]

I'm trying to make a 3D printer with inkjet printer parts so I would like better resolution

[@MySpace662]

Very educational, a video worth watching.

[@MarinusMakesStuff]

Oh no! I just took apart the linear drives of the printers that I had laying around, thinking this would be too hard to do. But now I see it's actually really easy!! I wanted to build a pen plotter with the old printer parts.. Now I'll have to salvage more printers haha :D So you use the 'Double H Bridge L298N' to drive the linear motors?

[@HomoFaciens]

Unfortunately, heaps of cheap, not long lasting printers are sold day by day, so there is no lack of supplies from old printers... Yes, the L298N boards are a cheap way to drive printer motors.

[@wasanthawimaladharm]

for people who are getting scribbling like drawings from DVD step-motor CNC plotter machine, i give you correct and proven changes for proper out put, try it and get corrected! (01) most people with "baby scribbling drawing output"due to low Watt power supply(less than 10W) SO give 5V 2Amp power supply - your cnc need (@least 10W power input) ,if not this will correct try with 12V, 1Amp power supply but this will heat up your DVD step-motors and 3 ICs of L293D so use fan to heat loss in 12v power supply. IF STILL SCRIBBLING DO CHANGES GIVEN BELLOW these changes should be done in Arduino CODES you upload to your CNC (02) StepMilimeterMax - for each 1cm of your maximum length or width of drawing area this value should be multiplied by 25, my cnc drawing area is 5cm X 5cm square shaped area, so my StepMilimeterMax is 5cm x25 =125 (every one who made CNC with normal DVD step-motors has nearly 5cm x 5cm area,so StepMilimeterMax =125) if StepMilimeterMax is 125 output is BIG pictures and letters WITH OVER FLOWING EDGES FROM 5cmx5cm (03) these factors given bellow should be in given values for 5cmx5cm drawing area (a) Line buffer -should be 512 ( if >512 effect is #) (b) XSetSpeed & YSetSpeed -should be 200 (if >200 effect is #) (c) Char Buffer -should be 64 (if >64 effect is #) #- unusual Hum and vibration from your DVD step-motors. (04) Line Delay - should be 50 if this is 0 - left half of your picture/text write on whole 5cm x5cm area and right half is over write on same 5cm x 5cm area if this is 50 - no OVER LAPPING (05) pen servo Delay- should be 100 if >100 - at the point of same text or picture section write by your CNC more than once, second and next writings are not write on first writing so this make "BLUR EFFECT" CORRECT YOUR ARDUINO CODES ACCORDING TO ERROR TYPE GIVEN ABOVE AND GET SUCCEEDED AND WRITE YOUR COMMENTS!

I will do my own code sometime but for now I will try using mach3 cause I want to get it working and then I will start to write code and stuff to use arduino. It takes a lot of time to do it propertly,I have to figure out how to get it to gradualy slow down before stop and have to do a lot of experiments with it. It is a lot easyer to do it with steppers cause I coud just buy drivers from ebay cheaply get code from someone else change few numbers and done. But I coudnt find software for dc motors so I will do my own that will be the best way to learn along the way. I didnt use your code beacouse I want it ti take gcode. But I will give it a try in future once I build another smaller one for fun. I am looking forward to see your future project that you are planing for 2017.
