Getting MK2 tomorrow, what should I know?  

Re: Getting MK2 tomorrow, what should I know?

Everything you ask about is available in this forum if you search some, but I have some quick tips:

- Use pure Alcohol to clean the build plate, it has worked out great for me. Window cleaner can be used as well, but some window cleaner contains stuff that ruins the adhesion.

- Print the noise canceling dampers. The printer is quiet by default but its just soo quiet with the feets.

- My best tip when it comes to removing stuff from the buildplate is to use a really thin spatula, and get it under the print.
If you print for example PETG or Flexible Filament, I usually print it pretty heigh. The layers seems to bond very well and the prints are removable. If I use the same nozzle height for the first layer of PETG/FilaFLEX its pretty much impossible to remove it.

- You can of course run it over night, what could happen is that your filament spool is tangling up, so make sure its not twisted/tangled if you plan to not supervise it.

Thank you.

I am a bit overwhelmed, there's a lot of stuff here but can be a bit scattered or specific. I have time to read but what happens is I see a subject and get completely derailed from my original intent so tips or tricks in one places just makes it easier (for me)

Should I be waiting for a print to fully cool, or trying to remove it fairly quickly with PLA?

I haven't seen any differences if I remove it right away or after 10 hours. PLA is cooled down directly so further cooling shouldn't matter that much.

Thank you 😀

Re: Getting MK2 tomorrow, what should I know?

Once again, I find it necessary to refer people to the E3D warnings:

Like all 3D printers, printers fitted with a high temperature all metal hotend can be a fire hazard. You are using experimental technology to heat and melt plastic, in a machine that you may have built or modified yourself, that likely does not have safety certification or significant failsafes. Fire/Smoke alarms, supervision of your printer while printing, and expertise should not be considered optional.

Please read and understand the risks you are taking when printing unattended.

EDIT: You should allow most filament types to cool before removal. Some will even self-remove. Other will stich like poop to a blanket.

Re: Getting MK2 tomorrow, what should I know?

My MK2 is due to be delivered tomorrow. I am coming off a different much cheaper printer and less refinded that had a lot of issues.

I have a few questions for anyone with a newer version like mine, so if you have the time, I would appreciate any advice. 😀

1. I want to have spare fans based on experience, is there a better/quieter fan(s) I should get than stock?
2. Are there any other parts I need to print (or purchase) right away to recover and continue printing from a possible part failure (it's going to be my only working printer)
3. Are there any "essential mods" for this printer I should do out of the box? My last printer required quite a bit.
4. Can I run this printer overnight unattended with just a smoke detector nearby (is that safe)?
5. How should I remove certain materials? I am still new to 3D printing and I was jamming a spatula under PLA prints on my last printer pretty much as they came out of the printer, I want to do things "right" and not damage the PEI. For example, should PLA cool completely down first before removing or remove when hot?
6. Any tips or tricks I should know with this printer?

Thanks in advanced for any advice.

What make/model is your old printer?

@pjr Please read and understand the risks you are taking when printing unattended.

I understand completely. Thank you for the reminder.

@ayourk

Thank you for all of that 🙂

Re: Getting MK2 tomorrow, what should I know?

By the way, I have an idea about fire safety. I have access to a fire suppression bottle, it's called a "Sun System Flame Defender". It's fairly new (pressure is good), I got it from my Father in Law. Not for any reason other than I collect odd stuff sometimes and his needs were greater than the smaller bottle version can handle. I once thought maybe I'd put it above my boiler or something..

Anyway, it triggers at 155 deg F or 68 C, I think something like that would be a good backup plan to attach it to my rafters above the printer even if I did not intend to print overnight ever. I will be printing in my finished basement, but not always be right next to it for every minute. any thoughts on that?

Re: Getting MK2 tomorrow, what should I know?

I should have also mentioned that some eSun cleaning filament can help clear minor clogs in the hotend.
