Re: An all metal hot-end design (Lots of Pics) - 12 years ago
Hi Sanjay, Thanks for all the additional info. I took another look at your pictures and indeed it's a resistor heater, not a cartridge. I mistakenly saw the hole for the resistor as the protruding end of a cartridge. It was an illusion. It's great that you are spelling out your thinking behind your design, and willing to take observations and feedback on board. From my own experimentation in staby NumberSix - General
Re: An all metal hot-end design (Lots of Pics) - 12 years ago
Hi guys, Interesting design. Some questions: Did you test it with just one fan and then decide it would need two fans or just presume it would need two fans? What diameter hold have you in the stainless insulator? (probably 2mm) Did you find this a challenge to drill straight through that length of stainless? How did you do the drilling? Looks like you are using a probe heater. What wattage is thby NumberSix - General
Re: 4032D PLA onto Cold PVA - 12 years ago
That's very interesting. You have done quite a bit of experimenting with pva coatings and cold bed printing. Can I just ask you to clarify some detail in your third paragraph above? You say a pure PVA coating is thick and hard to remove prints from, but then you say it's easy to remove prints from the thicker end of 1:2 coating. This seems a contradiction, but I'm sure you can clarify. When yoby NumberSix - Reprappers

Re: 4032D PLA onto Cold PVA - 12 years ago
Hi Takigama, That's very interesting. I'll have to try that out, the trick appearing to be a more concentrated solution of PVA when printing to a cold bed. My coating on the heated bed was about 1:8, and believe it or not I found that almost too strong a grip, and a challenge to remove once it had cooled.

Re: 4032D PLA onto Cold PVA - 12 years ago
Hi there, Just clarifying... are you printing to an unheated bed? What's the general room temperature? Are you in a warm climate? I've been using a PVA coating for the past few weeks and it works very well, but I use a heated bed. The PLA doesn't well at all when the bed is cold. Regards, NumberSixby NumberSix - Reprappers
Re: Lattest Wade's accessible extruder - 12 years ago
Hi there, If you are looking for something nearer the original Wade design (as against Greg's Accessible take on it) then Nophead has a version that has a 16mm hole. It's on his Mendel 90 Thingiverse page; It has the 50mm distance between it's mounting holes, same as Gregs, so will mount to many of the x-carriages out there.

Re: Our Mendel90 Build Experience and Mods - 12 years ago
It does look very well in white. The Mendel 90 is climbing high on my 'next printer' list! I like the sound of that PVC sheet. If you are getting it CNC cut then you could get a simple handle cut into the top cross piece. Not sure it's a portable size, but it would make it easier to lug around if you needed to. I'm also delighted to hear NopHead is continuing to evolve the design of the parts.by NumberSix - General

Re: Propeller Blade, Week of July 4 - July 11, 2012 - 12 years ago
Hi Andrew, That came out nice and clean. How easily did it separate from the supports? What did you use to slice it and what were your main settings? What material was it printed in? On a side note, have you coated your glass top to aid adhesion? It looks like something was brushed on to the glass and dried off. Hows that working out and what did you use?

If you've read this far then you may be located in Ireland and interested in finding someone locally that can print parts.

Re: Propeller Blade, Week of July 4 - July 11, 2012 - 12 years ago
I gave it a go using "Support" set to rough in KISSlicer, just to see how it might come out. I've never printed anything with supports before and it was an interesting experiment, even if the result was a bit patchy. I'm happy to share the experiment even thought it's not really a competitive contender. It does show it can be printed with supports and could be improved on with some tuning of theby NumberSix - Competitions

Re: J-Head Jam (premature melting) - 12 years ago
Hi there! In my experience of extrudes, you do need active cooling on the insulator (including the J-head) to remove the risk of jamming. I don't think this is emphasised enough to people. It doesn't have to be a strong fan, just a gentle breeze across it will prevent heat creep upwards. The fan may cool the heater block as you suspect, and you do have to take some action to prevent this. You canby NumberSix - Printing

Epic fail! Here's the result anyway! KISSlicer seemed to be doing better all the way to the top. I left it unattended and when I returned the nozzle had stuck and ripped it clean off it's base! oh well... at least I learned quit a bit about KISSlicer in the process. Enough for now.

Re: Dual Spiral Lightbulb / Week of June 09, 2012 - 12 years ago
Thanks Billy, That's great. You're using a gentle print rate, and there's no sign of any curling or pushing of plastic, which I'm running into. You must have some cooling going on of the layers just printed also. Once I climb out of the base into the tendrils, they remain a bit 'jelly like' and get moved about a bit by the nozzle printing the next layer.

Re: Dual Spiral Lightbulb / Week of June 09, 2012 - 12 years ago
It would be greatly appreciated if someone could share a quick video of the lower layers of this object being printed, showing the looping that forms the tendrils. It would give a better indication of how the extruder nozzle should be performing when printing this delicate piece. If you could pan to where your fan/cooling is positioned it would be an added bonus. I have managed to print this objeby NumberSix - Competitions

Well done Billy! I think you’ve sent the community on a trawl to see what interesting machine produced such a neat looking print. I’ve certainly taken a moment to step back and review your work. You have caused me to question some of the sudo-fundamentals I’ve followed, such as “threaded z-axis is better” (you have belt driven Z) or “Nema17s are best” (you appear to have Nema14s all round).

Hi David, Sort out any wobble in the hot end. Even if you are filling in at 0 and 90deg the filament should lay down perfectly straight. Temperature considerations...

Hi Brad, Great work. I like the compact design. It may well serve the needs of many better than a larger print area.
