Hello both, thanks for your input. dc42: I wanted something tiny to drive the steppers and fits under the stepstick drivers, I don't need any other features, and I use Marlin which wasn't officially supported on 32bit boards at the time. Also, I don't need or use a high pin count 8-bit mcu (atmega1284p has less pins that Arduino Mega atmega2560) and it doesn't cost twice as much as the ATSAM4S4by mbhassan - Developers
John, I am afraid I'm having hard time imagining what you're describing. As for printing on the table, that would be cool indeed. You'd most probably still need some print surface on the table for the filament to stick to it though.by mbhassan - Developers
Hi Ryan, First of all that's an awesome build, I hope it's still alive and kicking. As for my design, I am aware of such requirements. I was originally designing mine with steel inner structure and carbon fiber housing and using relatively expensive components, unfortunately at the moment that would also mean higher price, which is currently the biggest challenge that I need to work on if thisby mbhassan - Developers
You almost certainly know more than me, not to mention I'm biased (the reason I'm working on this in the first place is because I like to have one). Anyways, regardless of the commercial potential, I'll keep working on it and publish updates on hackaday.io and my website, if anyone is interested.by mbhassan - Developers
Peter: I definitely will continue to make and improve one for myself, I actually need one at the moment as I had to give away my regular-size desktop printers due to moving to a city centre flat, so no space for hobbies. But I also wanted to make some money. Yes, I totally get your point, it's hard to compete on price with Chinese mass production. But as you said "some of them are ok", there isby mbhassan - Developers
Thanks for your replies. o_lampe: Yes, there are a couple of PWM pins, but that depends on how many end-stops do you plan to have. Because I didn't have any space on the left side of the board (I needed at least two expansion ports, one for extruder and one for bed), I broke out the two PWM pins on the connectors that are originally intended for the x-axis end-stops (see here stepZeroR2 pins).by mbhassan - Developers
Hi everyone, Many years ago I have made a couple of attempts at designing a portable folding 3d printer (Project Create and Project Resha). Back then I had very little money and time due to my studies, which prevented any meaningful progress. Now I have slightly more time, so I decided to revisit the latter design, though progress is still too slow. I had thought that by now someone would haveby mbhassan - Developers
Hi This is something I've been working on for a while, take a look and let me know what you think Hope you find it interesting Muhammad Badrby mbhassan - Look what I made!
وعليكم السلام ومرحبا بالطبع يسعدنى التعاون، لكن مع الأسف كما ترى أنا لست مشارك نشط فى المنتدى حيث أنى مشغول أكثر الوقت بتحضير رسالة دكتوراه أتمنى أن أسمع منك قريباby mbhassan - Arabic RepRap User Group
I'm glad to see someone thinking along the same line, I'm even happier to see someone referring to my work, thanks Sublime, sorry about not posting any updates, I'm a bit busy and the lift mechanism is quite tricky specially at the targeted overall size I did a small modification to a Marlin firmware for the purpose of testing the mechanism, in my case the bottom side of the scissor-lift is closby mbhassan - Mechanics
mmmm, I've a feeling that he wasn't askingby mbhassan - Look what I made!
I didn't got to test the modified designs yet, I'm still waiting for some essential parts to arrive nothing new on the blog for now, but hopefully I should be able to put the new prototype together early next week and maybe post something when I test itby mbhassan - Look what I made!
Sorry I've removed it for now, it seems like I need some more time - and money :-) - to get it working enough for publishing, both of which I don't have right now I'll post on the mailing list once I get it workingby mbhassan - Robots!
I'm posting about this in all relevant forums, hope that doesn't annoy anyone I'm working on a folding printer, and launched a campaign to help with the development costs on indiegogo sorry about the short video, I'm working on that, check the gallery section for a couple more short videos I haven't yet edited the wiki page, obviously it will be here , it seems building something is much eaby mbhassan - Developers

lol, sorry about that, I guess it's now quite obvious that English is not my first language :-) I hope and intend to go on, thanks for your commentby mbhassan - Robots!

well, it's not printing yet, I'm launching this campaign because I'm short on funds, I wouldn't have any spare money to spend on testing until about the 28th of May, so I though if people are interested maybe I can raise some money to speed things up there is a video in the gallery section showing it unfolding to about half way up thanks for your feedbackby mbhassan - Look what I made!
Hi all, this is my first post here so I'll start by introducing myself My name is Muhammad Badr, I'm a mechatronic system engineer and I'm currently doing a PhD in robotics in Sheffield Hallam University I'm posting about this in all relevant fourms, I hope that wouldn't annoy anyone I've designed a new 3D printer and launched an IndieGoGo campaing about it, please take a look and tell me whatby mbhassan - Look what I made!
Hi all this is my first post here, I guess I should introduce myself My name is Muhammad Badr, I'm a mechatronic system engineer and I'm currently doing a PhD in robotics in Sheffield Hallam University I'm currently launching a robotics business, I've just launched a campaign on IndieGoGo to help me get things going yup, I'm kinda marketing my stuff here :-D I hope I'm not breaking any ruelsby mbhassan - Robots!

hi all Sorry for being away for so long, I kinda forgot about this thread when I got a feeling that not much people are interested now that there are so much interested, I'm more than honoured to participate in the reprap arab community I apologize for writing in English as I'm using a university computer that has no arabic keyboard layout I'll write again when I get home in arabic BTW Badrby mbhassan - Arabic RepRap User Group
mmmmm, I don't know how to use Skeinforge I tried it but got lost with all those buttons and settings, I know that ReplicatorG uses Skeinforge, but I didn't know how to adjust the settings for direct drive stepper extruder, I'll try and search again for some explanation to set up ReplicatorG or to generate the gcode directly from Skeinforge, if you can help me with that I'd really appreciate it,by mbhassan - 3D Design tools
Hi, I don't get what u mean by "won't skein", if u mean thin boarders then the answer is no, I've tried many designs but unable to build any, for example the attached pic, when i attempt to build the base (at the very bottom of the pic) using repsnapper, it only make gcode for (and print) the thin triangular base but not the part holding the servo,by mbhassan - 3D Design tools
First I apologise if this is repeated, but I've went through all the posts that I could find and had no satisfying result also this is my first post so please don't let me down, my story, I've been having some hard time trying to run my CNC router as reprap, all troubles regarding the software, the only one that seems to work with me is RepSnapper with tonokip firmware, now I'm trying to designby mbhassan - 3D Design tools
