For calibration, I typically start with extrusion temp using this. Them move to extruder steps/mm, then x/y steps/mm and scaling. Also, you don't have to print in 0.1mm for calibration. I typically do 0.2 just for a happy medium between speed and resolution. Lastly, I know the E3D sometimes has problems with PLA (I know mine did). So keep that in mind if you end up having a tough time gettinby gmh39 - Extruded Aluminum Frames

QuoteNewPerfection Quotegmh39 They are using a price of $43.93 for PLA. I would say that is on the higher end of the filament pricing. Something around $35 would be more appropriate IMO. But none that less, that is freaking cool! $35/kg of PLA is $0.042/ml to $0.049/ml (1.2g/ml to 1.4g/ml density of PLA) $40/liter of resin is $0.04/ml There is cheaper PLA available, and more expensive resiby gmh39 - General
QuoteDust I normally print at 170 for PLA, it does depend on your pla and what hot end you have, but 200 for pla seem really high to me. 200 PLA is not unheard of. Im currently printing at 210. It could be dirt/dust that is getting burnt up in your hotend. Try taping a cloth or sponge around your filament as it enters your extruder.by gmh39 - Printing

AFAIK, multi-filament hotend/extruders are still in the prototype/development stage. If you really want one, you can do some research on them and I am sure someone has posted their prototype parts online somewhere. Then you can print them out and build one yourself. Are you printing single objects in multiple filaments? Or do you want to be able to just use multiple filaments (ie. print a briby gmh39 - General
Quotetjb1 Misumi is similar to McMaster in that they don't quote shipping unless specifically asked to do so but the similarities end there. McMaster actually does an invoice quite quickly, Misumi on the other hand took a week and repeated phone calls after I RECEIVED the order before it was invoiced and charged.

QuoteNewPerfection Quotegmh39 Why are they using a proprietary 2.85 mm filament? Ok, it might not be proprietary, but it is a none standard size... 2.85mm is a standard size. It's just called 3mm usually. Filament that is actually 3.0mm diameter is uncommon. Hmmm. Didn't know that. I've never actually used 3mm filament, although I have a huge box of it...by gmh39 - General
Quotecameronm Hello Eric, I have a couple of questions about the hotend. What type of stainless steel are you using for the one piece nozzle? Have you ever used taulman T-glass with it? I would be interested in using this with T-glass because T-glass is food safe and was hoping this was too. Thank you, Cameron Anything that goes through the hotend is no longer food safe. Unless of course theby gmh39 - General

You could also use a thin piece of aluminum and stick a kapton heater on the bottom. Then glass on top of that. Idk if thatll be too heavy or not though. If you print the mounts with ABS and put PTFE washers between them and the bed, they should be fine.by gmh39 - Smart_Rap

ok, so you wan to sell it for pretty much the same $/yard. That's a good idea. You should definitely only sell high quality filament. I know there are a lot of people who only buy from 1-2 sources simply because of the quality. Also, if you aren't already planning on it, it might be a good idea to have a proper How-to on testing filament, suggested length for testing, and maybe some sample priby gmh39 - Crowdfunding Projects Announcements

So you are selling a hot plate for $85? Also, your company is called Open Source Printing, LLC, are you going to make the design open source? I would sure hope so... PS. You've got some pretty bad z banding going on in those prints...by gmh39 - For Sale
I can tell you right now, it is not the best idea to go big right from the get-go, especially if you dont know much about the technology. I am sure others will point this out, but when you go big you will need to be VERY careful about reliability. Instead of taking a few hours to print, a large scale print can take DAYS! and if it fails 2.5 days into a 3 day print you just lost a lot of time anby gmh39 - General
