At those temperatures, you might as well get external air funneled in, i mean that is how Stratasys does it. Also like DjDemonD repeated, temperature on the hotend is regulated, and it is still a heatsink and it will not get hot enough to melt it. Also if you were to use a fan internally such as on an E3D, your fan has a much much higher chance of failing than an external pump. Also, no I do notby 3DRapidClone - General
How are you incorporating the water-cooled hotend? Utilizing properly sized barbed fittings and clamps is necessary. You don't need to fear water cooling if you build it right. First, if you have a heated chamber, I'm assuming your heated bed is insulated on the bottom as well. Heated Chamber or not, your electrical contact points should not be exposed. It should be appropriately sealed with or wby 3DRapidClone - General

Quoten8bot The PrintBite seems to have an advantage with Nylon, and other high temp materials, but I'm not sure if that's really the case or marketing fluff and misinformation provided from inexperienced users. Most "serious" DIY 3d printer builders I know use PEI, but I could see a use for PrintBite if you ONLY printed Nylon. I still have my doubts how well it holds onto REAL nylon, and not theby 3DRapidClone - General

Hey guys, just have a question about multiple triggers via the M581 command. If say you have an out of filament switch trigger (NC) for extruder 1 (M581 E0 S0 T2) and in the Trigger2.g file you have something like: Trigger2.g M117 Out of filament M25 ;runs pause.g (no retract portion in it) G1 E400 F500 ;for example MXXX GXXX ..etc and new filament triggers that same microswitch, but a differenby 3DRapidClone - Duet

Well if its a tool change, then its most likely not your configuration file. That's more for steps/mm and if your 2nd extruder is heating up and what not. This is more likely your Slicer settings during the tool change, can you post that gcode?by 3DRapidClone - Delta Machines

QuoteTreito Most reports I have read so far where about a PEI coating on an aluminium surface and I got warned about a nozzle crash. If the nozzle is hot the coating would be seriously damaged. So I never considered PEI and I never will consider it. Not for that price model. That's a really thin coating and thus can be scratched off. PEI amber sheets from amazon can handle a ton of abuse.

It is not PEI, its a composite material as nylon can adhere to it, where nylon has no interaction with PEI at all.by 3DRapidClone - General
Quotenebbian You're not wrong DjDemonD, I've been going down a similar thought pattern myself. I'm also considering a coreXY, if only to finally be able to get repeatable prints (within 0.02mm) when printed in different areas of the bed. A flying extruder on a CoreXY would give the best of all worlds. Strange that you can't buy a commercial CoreXY yet. You can purchase the fusion f306.by 3DRapidClone - Delta Machines
Where did you get that Deltas are more accurate than cartesian systems? They aren't. In fact they have varying resolution across the bed. I would recommend something like a CoreXY build or a well built Kossel with linear rails/Vslot and aluminum corner vertices.by 3DRapidClone - Delta Machines
QuotePRZ I have questions about adhesion of some products. I have adhesion difficulties with 'silver' PLA (esun brand), which have very low adhesion and need much higher temperature than other PLA.

An unstable Z would cause your layers to overlap, and quality to drop and could clog your nozzle. Smaller the better for less ringing. As for the delta stuff, autocalibration is a big thing now and as for tinkerering, delta kinematics is not as easy as Cartesian and I find that statement about not knowing what's wrong incredibly false, but most of my experience is,with deltas.

QuoteDalius98 That's quite similar to what I've been thinking recently - building a smaller printer is just easier... They are much easier to build. Quote3DRapidClone My printer is 14" diameter and 18" tall in build volume which is just about right for me. I take it you have a delta printer then. These seem to be easier to scale, right?

12mm rods will be pretty heavy, and with the linear rod bearings you will get a lot of ringing. At those sizes above 200mm, there's more engineering required to actually scale a printer up. about 8" cubed, its pretty simple, but above that you have longer canttilevers and weights that you must deal with. 12" cubed is pretty good, any larger is extra bonus.
