I started watching this with little interest but I realized that the specific issues you fixed deserved attention. This post is instructive from that point of view.
Having stumbled upon this channel by accident |I immediately subbed due to the level of detail and research. Also, your uni-polar stepper motor driver module was a genius work of art. I salute your tenacity and methodical workmanship.
As you can see I put a hell of a lot of effort into this video 😅 But my computer definitely doesn't like editing these complex 15+ minute videos with loads of animations! The editor crashes all the time 😒
I watch this amazing video again, just to hear you explaining the .gcode file. I came across that issue when switching from a CNC laser with a fixed Z to another with programmatically adjustable Z. Fixing the issue was less hard than the amount of investigation you've been through, a terrible challenge actually. With standardized design e.g. 3018 CNC .gcode files are often harmless even those containing exotic codes.
I think since pen plotters are kind of a niche product nobody really needs a lot of people have messed around with the software without there being one universal build (like marlin for 3d printers) everyone inexperienced can rely on... No idea why someone writing an Inkscape extension _specifically_ for a grbl plotter would make it run commands grbl doesn't understand, but for some reason that seems to be what happened.
Awesome ,simply great 👍 sir , it's an request sir , why don't you design your own arduino uno circuit to control the plotter , the way you designed PWM circuit using transistors. And a 433 mhz transmitter and receiver module circuit used for RC toys etc
Amazing! I’m 14 and I’m building a laser cutter from old inkjet printers and 28byj-48 stepping motors like yours. I made sure to subscribe and like. Someday I’d like to make a little money from doing projects like these also because I like doing videography also.
Not sure how far you have got with these projects but using arduino uno with grbl shield yields results (use the grbl shield drivers instead of the ones that come with those motors. The grbl shield does away with a lot of fiddly wiring etc). If you use Makelangelo software you can load a svg and it will convert it to gcode. You can modify that gcode and get some pretty good results in terms of shading and effects (Makelangelo is software for polagraph plotters hence you need to tweak in something like notepad or Excel). I used two nema 17 and one 28BY-48 on the Z axis. The use of glass as the surface is good.
I've since made an entire series about a new plotter which I ended up designing my own controller board for. Sure it's easier to use a shield, but the point of the project was not to waste fancy motor drivers on a toy I get bored of after 10 minutes :)
@@ChronicMechatronic I can tell you love the torture. Good though that you've gone the way you have. It's a good way to learn. I've tried to keep the cost down. Couldn't imagine buying ready made plotter.
Yeah, you need to modify the stepper.c file inside the grbl library in order to acommodate a third unipolar stepper motor for the z axis. As far as I know, that would be done by adding a third variable underneath the line: "int costyy=1;" and then copy/paste/adapting the stepper motion control blocks (the if blocks going like this: "if(costyy==[...]) PORT=[...]" into the segment that does the z axis. Now the part I don't know, is how to route the pin configuration in the cpu map - I'm not very good at coding, but I hope this helps :)
Moro no Brasil, sou louco por eletronica, nao possuo muito conhecimento, montei uma mini CNC que funciona bem, mas tenho dificuldades em criar arquivos em G-code, pode me ajudar???
Yes, but I believe I mentioned that in the video, and I specifically showed a screenshot of the robottini adaption. Sorry if I sound annoyed, but I wish people would watch the entire video before asking something that was actually mentioned in it - seriously, why do I even bother making an _entire_ video if everybody watches but 20%? But thanks for commenting anyway.
@@ChronicMechatronic I did watch the entire thing but i did not notice this detail .Sry :(. I also watched the second build from the beginning to the end :).
Oh okay, sorry I was so harsh then :/ I just get it a lot on more popular vids, and it really leaves me wondering why I even try cram in as much information as possible... For the second build I'll go into much more detail on the entire software and electronics part, cuz it seems a very badly documented area in general :)
Hello dear brother. I'm sorry, but I want to help. I did all the steps in the video, but only one motor works, but the x axis motor and the y axis motor do not work. What is the problem? Thank you
I am sorry to disappoint you, but like I mentioned in a couple of videos I am just a beginner at programming myself, so I already have troubles getting my own stuff to work. Let alone being able to pinpoint an issue by a mere description. The only advice I can give you is: do more research, try to understand what each piece of code is doing, and don't ever give up :)
For the new plotter I'm currently working on I'll go into much more detail on the electronics and software part, as well as share all the circuit diagrams & design files :)
Hello, sorry to disturb you. I like your writing machine very much and want to make one by myself, but I cannot find a suitable L-shaped bracket. I would like to know what type of mrtal L bracket you have or do you cut it by yourself
No worries, I cut the L brackets out of an old computer case, however I really don't recommend this linear rail system at all, since the aluminum U channel itself usually isn't precise enough (inner width varies by a surprising amount) sanding the brackets till they really fit is quite a pain... If you look at my my more recent videos I'm currently building a plotter with a new linear rail system that should be much more forgiving when it comes to fabrication accuracy as well as changes in humidity. I hope that can inspire you, since the aluminum U channel rails really weren't that reliable, even though they're made from metal...
nice video man . great job , i have made the 3d printed version of the same which uses the same stepper motor on the pen aswell. im facing issues of the plotter not drawing as it should all the shapes are not smooth and most of curves getting flat line. any idea what could cause that - im using JSCUT and sometimes the same extension in inkscape. still not getting smooth lines all wired flat and not organized lines. the motors im using are 28BYJ-48 5V with their drivers and an Arduino Nano . been 2 weeks working on it to fix the problem , still not getting lucky :( hope you can assist me
Hmmm, weird... What Gcode sender/CNC controller software do you use? I've had that problem with the straight lines with another Inkscape extension I used before switching to gcodeplot. Also, if you have 3 steppers with their uln2003 drivers, what version of GRBL did you flash to the arduino? I've been wanting to develop a fully unipolar CNC for a while now, but modding grbl to acommodate a third uln2003 driver is beyond my coding abilities...
