You've got a lovely looking dome! What different lengths of struts did you use? Does your open source home project have a webpage? If you don't yet know it, do take a look at a book called 'Tiny Homes, Simple shelter' for some inspiration. Good luck!by Squags - General
Hello all, I'm writing a masters thesis (due end. Sept) on budget 3D printing and am hoping for a little help. The basic format of my thesis is below, with most emphasis being on the last chapter, for which I have done several months of experimental work. Chapters 1 and 3 are easy, so I was hoping for a little help with Chapter 2. Chapter 1: Brief history of manufacturing (towards 3D printingby Squags - General
Hi all, I've just put together my 2nd Ormerod, which seems to have come with its own problem: The X and Y calibrations aren't right, meaning circles don't come out right - see picture... Any ideas what I can adjust to try and sort this problem? Cheers, Squagsby Squags - Ormerod
Hi, Sorry for the delayed reply. Here are some photos of my big blue (unfortunately black, so hard to take suitable photos). It seems that it's a couple of mm too close to the x arm to neatly fit beside the z axis assembly; hence why it's hitting rather than going to the home x position. If i've missed anything obvious do let me know, but don't worry if not - i quite like the look of your probeleby Squags - Ormerod
My big blue - or big black in my case is now up and running and the bridging isn't bad - though not as good as what you managed. Just a couple of questions: 1. The big blue is quite high relative to the nozzle, so on mine at least, the air is being directed mostly at the aluminium block, which may well be explaining the phenomenon above. 2. Going to X-axis home position doesn't really work. The eby Squags - Ormerod

Does anyone have any bright ideas about modifying the power supply in the following ways: timer switch, so it'll turn machine off either after a preset time (do-able with cheap socket timer), or when G-code is finished smoke alarm - getting a bit worried after this: Cheers, Squagsby Squags - Ormerod
Put me down for an x rib and x plate please. When the time comes, please let me know payment details and I'll PM you my address. I would also be grateful for a moderately official looking receipt as I can then claim it back from uni. Thanks, Squagsby Squags - Ormerod
Just a word of warning to anyone doing this modification... Don't be tempted to take the hot end bits apart to give them a clean or reposition them drastically... I made that mistake this evening... I only wanted to turn the hot end 90 deg, but stupidly still had some filament in the pipeline, so it kept flexing back and wouldn't stay where I wanted it. I heated it up, removed the filament and thby Squags - Ormerod
I'm printing my Big Blue 360 rev 1a now and it's so far looking good... I've just nipped to the shop and bought a 2nd 40mm fan in order to get a bit more air through it. Looking at the reprappro site it says the existing fan is 12V (though as I'm printing, I can't read it or get so somewhere to measure it for sure) - maybe someone could confirm? I assume I should just wire the 2nd 12V fan in in pby Squags - Ormerod
Here's another vote for printing on glass... I've been printing a lot lately making and evolving prototypes and even really detailed bottom layered parts have been sticking perfectly - here's my receipe: 1. Let bed heat up to almost 80C using pronterface. 2. Spray on alcohol (I use record cleaner - not certain quite what it is, but basically smells like thin alcohol spray) 3.

My little local electrical shop had a replacement for the green power terminal connector thingy for all of 55 euro cents. Replaced and printing again already - but on the look out for a spare smoke alarm just in case!by Squags - Ormerod
It appears after 3-4kg of printing, one of my power cables must have worked a bit loose... Having recently done a 36 hour print, I feel very lucky I happened to be in the room when the smoke started. Check your cables people! Is there any way of resurrecting this power board? If not, any chance of a replacement?by Squags - Ormerod
Looking great. I've just come back to this forum having been printing away happily for the last couple of months... This looks like a great mod, but I don't fully understand it... What's the plastic enclosure to the right of your photo? Looks like it's housing a PCB of some sort? Is this also required? Any chance of a photo of big blue mounted to the machine for the dumb among us?! Thanks, Squagsby Squags - Ormerod
Hi, not sure what the answer is yet. Your gcode doesn't seem complete... You can check it with this website to see for any obvious errors: But i imagine it's a mechanical/motor problem. I've occasionally had something similar, but never regularly or twice on the same printby Squags - Ormerod
If you look on youtube you'll see videos of people using solder in a 3d printer. The results seem pretty poor compared to plastic, but fun none the less. I've just persuaded my uni to pay for all the parts needed to design and build a hot end that'll (hopefully) melt aluminium wire. If successful I intend to make a hot end that can be used with reprap printers (along with an enclosure and argon sby Squags - Ormerod
The solidworks files are provided (on github, i think). Solidworks is probably pretty expensive, but really useful and readily available for free for most students (and probably illegally for non-students). I would recommend getting a copy and learning it if you're going to be doing modifications and/or engineering based 3d printing.by Squags - Ormerod
Hello, Thanks for your reply. Forgive me if it's been tried before. I must admit to having only been on this forum for a couple of months (and mostly in the Ormerod department) and/so haven't personally seen any similar suggestions; though if there are any machines/threads you could point me to it would be great to learn from their experiences.

I would advise you to have a look at some 3D printed objects before diving in... While the resolution is very good, I hadn't realised before buying just how much surface finish of a product matters. Look around you - your keyboard, mouse, monitor, desk, lamp etc.... Some of these things wouldn't suffer from having a slightly serrated edge, but others really would.

I tend to unplug the printer usb cable once the print is underway. The printer then stops. I then plug it back in and out again, which makes the printer resume and carry on going, even when no longer connected. Hope that helpsby Squags - Ormerod
Thanks for posting this... I made the same mistake and have printed almost a kilo of things; so have been rather lucky that it's been without incident. Thanks again... Sharing mistakes is never a mistakeby Squags - Ormerod
Glad things are getting better. From observing printing, I think most blobs occur during layer change/ when the extruder starts again. I would guess therefore the most important things are the tip temperature (the optimal could well vary with different filaments) and extruder settings. I haven't yet played with the later, though there are several variables in slic3r under printer settings - extby Squags - Ormerod
Firmware 57a is the latest - though I'm currently only printing from SD card, so not personally sure if this is working with the pronterface USB fix I would try adjusting Sli3er settings: See other posts for details, but here is what's worked for me: Retraction to 4mm, Temps: 1st layer, 195/70 then: 180/65 Fan always on (don't know if this makes a difference, but seeing as the fan is always on, Sby Squags - Ormerod
First thing to note is that having printed the part in black, the (re-calibrated) IR sensor is now far more accurate at homing the Z axis - Where as before I had a value of 687 at 0.6mm, with 897 at 0.1mm; it is now 698 at 1.7mm and 974 at 0.1mm (with the same lighting conditions as before). It's a complicated part and as such if your printing quality isn't spot on, it's important to fettle and fby Squags - Ormerod

Hello all, I have been working on an improvement of the x axis carriage, hoping to overcome the following issues: X-axis sag: I bought a 10mm bearing, but it was a pain to find and still not as tight fitting as I would have liked.

Hello all, I'm fairly new to the world of 3D printing, reprap and opensource stuff; so excuse me if this is a daft question...
