Thanks everyone! I am resisting the urge to splurge, there's a fatal attraction involved with power tools so I'm going to seal my wallet in amber until I've made a sensible choice. My gut is going with band saw as it feels more precise (from what I remember from metalwork at school), although I also found this which will go through steel comfortably.
The sort of things I'm looking to shop are b

I've seen posts about using a miter saw with a carbide blade for cutting aluminum extrusions. I purchased one for that purpose but have not actually cut anything yet. If your pieces are less than 4 or 5 inches in depth, the miter saw might work.
Do you have a link to the blade you have? Many thanks!

Quick, go to the garage, workshop, where ever you keep it and cut things then report back!!
I will investigate Mitre saws though, it makes sense.
Been researching band saws and came across this forum. The link is to an interesting discussion of cutting thick ali with band saws. Thought it might be of interest to anyone else thinking along these lines. (EDIT: I'm only interested in thin ali, bu

Struggling with band saws. They all seem to be wood working oriented if they say anything at all. Any clues for what to look for? I would assume it's more to do with the belt than the actual saw as long as its powerful enough, but all the belts I've looked at aren't giving away anything.

Band saw could be an option, that would give accurate cuts and a bit of extra flexibility.

What are the options for power tools for cutting sheet aluminium? say 4-6mm sheets, for fairly small areas, nothing overly detailed, but possibly making a lot of similar parts?
I was thinking something in a table saw, but all the ones I've looked at seem to be only for wood.
Thanks

I'm being dim and don't understand what turning it upside down does. My filament for example is above the printer, so I would of thought feeding the filament directly into the top would reduce the flex the most. That's what I would of done in my naivity

Interesting. I was looking at options last night and all the non-bowden assemblies look very very heavy, so I think bowden is the way to go. I thought I might start with one bowden just to see what effect it has on printing, I understand you get hysterisis (?) as the hot end is remote and the filament can flex/absorb some of the push between extruder and hot end.

Assuming you're doing using one of course. I'm looking at options for my i3.

Perfect thank you. I hadn't considered just wiring them to the input actually. I have a fan on that pin out already, so hadn't thought much beyond there. the fans are 0.16amp, but I can't see the width of the track without pulling the board off which I can't do right now.
Thanks for the great answer though, I learned something useful.
Cheers

Perfect thanks I found a different one on Thingiverse when I looked, but it was for attaching to wood, so no use to me

I want to add a few additional always on fans. I currently have one connected to D2 (the two pin output just below the 12v in). Can I safely connect a couple more fans to this in parallel without adverse affects?

Hi, I've got a full graphics adapter on my i3 badly affixed to the top with the mounts designed for the 2 line LCD. Does anyone have an STL for a better frame? I might try making one, I really should learn how, but until then...

I wish I knew where. I've been playing with different versions of Slic3r, and they all share the same settings location, and thus settings, so f knows where Pronterface is looking.
Here's my latest print. The square at the top is my .5mm wall calibration piece, and the robot is a robot.
The robot had a few issues with support material, I don't really know how to control that yet, the slic3r set

Quote Y-Moves positively **excitement** but not negatively
Not sure if this is the same with Sprinter as with Marlin, but until you do a "home" operation, you can't move negatively. I assume this is some sort of preventative, but not actually sure. So try hitting the home button for Y in PronterFace.
For the four wires, you wire the two grounds together.
For the stepper drivers. It's easy to

Hazaah! Ok, perhaps this will explain everything. Hopefully you can tell me
I've been using Pronterface. I've been changing settings in Slic3r by starting it using the slicing settings menu option in pronterface. I'd then open an stl (Actually usually i'd close Pronterface and reopening it (I'm sure I read it doesn't reload the settings or something)) and print it. In this way I had to use an E

I couldn't find a hot-end/extruder sub forum. I assumed there would be as they're important. Where do hot end questions go?

Stumbled across these people (I'm in the UK) and found this mill which seems like a possibility for three axis (It's got x,y,z). I'd really like to be able to rotate the item being milled as well, so that's four axis???

Here's the pic of my nice cube for reference. It's pretty accurately 1cm per side. Still looks a bit like it needs a bit more feed rate though close up.What do you think?
I've asked a question here which is directly related, but felt it should go in the slicr section. Not sure.

Hi, I'm working through this calibration guide and I don't follow the "Infill" section. It says:
QuoteSet infill solidity to 1.0 for this, using linear infill. In Pronterface/Skeinforge settings, this can be found under Craft > Fill.
Print the cube and analyze the top. If there is NOT ENOUGH plastic (a concave top), reduce the Infill Width over Thickness by .05 increments. If there is TOO MU

I'm quite keen to pick up a mill for small metal work. Two things come to mind. First is build it! Second, and probably more realistic right now is Buy it!
But there don't seem to be many if any viable little mills, let alone CNC ones.
It doesn't have to be CNC, manual is fine for now. I had considered this but apparently it's not very accurate. To allow one axis to move loosens a second axis

Yes, sorry I should of been more specific (more on that in a second). That's the measure of the cold filament passing through the extruder without hot end.
On the being specific, I've learned a few important things over the last week. One is that some measures are in mm per min and others are in mm per second for example. That gave me a headache until I read the comments properly :/

I'm doing the calibration guide now, It's good for the most part, but vague in others. I'm struggling a bit to understand my current results.
The 3mm wiblet on the right is the best I've got so far, so i moved to the next step, printing the 0.5mm wall item. As you can see it goes a bit wrong.
I changed the layer height in slicr down to 0.15 and specified a wall thickness of 0.5 (as opposed to

Hello, any pointers on what this print is doing wrong would be appreciated. The print is of a 1cm cube. The base is 1cm per side. Height is 9mm. Top surface is 9mm per side, so it tapers a little. There are obvious gaps between layers

These are the settings I have currently, I've actually just tweaked them down, so waiting on a print...
#define HOMING_FEEDRATE {50*60, 50*60, 100, 0} // set the homing speeds (mm/min)
