3D Printing 3D printer plunge

[memcbride]

The Prusa plain PEI bed seems to have good adhesion al by itself for PETG (Amazon Basics brand). I tried Chuck’s tip of using a bit of Windex as the bed approaches final temp - way too much adhesion. Simply cleaning the bed with alcohol and printing is showing good first layer adhesion and easy release. For now anyway.

I have had good luck maintaining adhesion on the Prusa PEI bed with a quick wipe of 90% isopropyl alcohol before each print starts; until just the other day. Went back to the Prusa support and they say to wipe the PEI bed with acetone once a week. Did that last night and good adhesion returned.

Know that video well! Good tip.

X3. I use acetone about every 2 weeks. Heck, it even works on the PC TXT bed.

Good evening everyone. I thought I would pop on in to say a few thoughts. Fascinating thread on the beauties of 3D printing. Oh, and while I am here, I would like to clear a *few* things up.

I installed Octoprint and a Raspberry Pi. This little addition really allows me to control and monitor prints after I leave my apartment.

So, CW, you installed OctoPrint, did you? Funny, that is not quite how I remember it. I remember a collection of insignificant details that differ.
So you flashed the install of the corrupted NOOBS install we received from Adafruit? So you realized that Octoprint ran only in a text-based environment and to have Octoprint run with a desktop, you had to install Raspbian and then install Octoprint on top of that, how to get the web browser to boot up to the Octoprint client, and figured out how to connect the 3.5 inch screen that is no longer supported by Raspbian out-of-the-box? And did all of this with a splitting headache? You're welcome by the way.

On the Octoprint topic, I also installed it. I downloaded Octopi, and the setup was straightforward. I’d recommend it, and this video which takes you through the procedure:
Works as advertised.

Well, I have to admit that my son made this possible. I am recovering from a clogged extruder and influenza right now. Since he brought it home from school, guess he made both the octoprint and my illness possible.

 

[TheSpawnOfCW]

Your welcome! Have fun!

It is interesting to see the metaphorical evolution of language as new technology is developed, leading to new euphemisms in the vernacular .

 

[cwbullet]

Yup. My son took the printer apart today and it is back together and works fine. Amazing, he did it without cussing. It would have not happened this way if I had done it.

Do you mean that the printer would not be working if you had taken it apart or that you would have been cussing the entire time?

You would have made sailors proud Dad.

Where is the best place to buy the best newest version of a Raspberry Pi Zero W?

I always buy form Adafruit.

I had a clogged extruder and found Miralax to help.

I’m a Sparkfun customer, get most of my electronics from them.

 

[cwbullet]

Sparkfun is also a good source and they are reliable. Price shop both.

Do you have a phone number for them. I have sent them 3 emails now and none have been answered.

They also do not answer their phone and their emails.

[matthewdlaudato]

I don’t recall having to call or email Sparkfun, I order online and stuff shows up.

I understand that but I have a few questions that need answering?

Jim, try pinging them on Twitter or Facebook as well - I suspect that being called out publicly would get their attention. Also if you create an account on their site you can live chat with support (about an order). They also have a forum with a robust user community.

Are your questions about an order or are they general product inquiries?

Chuck,
What is the product ID from Adafruit for the headers that are needed for the Pi Zero W for the Prusa? I saw that they need 18mm long posts?

Jim

 

[cwbullet]

I will check when I get home. I Built one with a 3b and second with a zero

Which do u prefer? The 3b or zero?

 

[cwbullet]

3B was easier to set up and does not require soldering. It is also more powerful.

I used these 20mm ones from Amazon: uxcell 10Pcs 2.54mm 80Pin Double... https://www.amazon.com/dp/B00R1LRRL6/?tag=skimlinks_replacement-20 They worked fine.

 

[cwbullet]

I just checked. The 20mm ones are what we used. I have two. One zero mounted in a case with the Prusa and one on top with a touch screen(3B).

 

[gorillamotors]

Thanks

 

[gorillamotors]

If you were to buy only one card, would it be the Zero W or the 3B+?

 

[cwbullet]

3B+. More versatile and no soldering.
