Just saying hi and a simple question

Hello

I just received my I3 MK3S in the mail and finished assembling it last night. This is an amazing product, the assembly instructions were very clear and easy to follow. The wizard came back with no errors on the first try and I chalk that up to the instructions. The care and attention to detail really shows that you guys are passionate about your work. before this I had a mp select mini to see if I was gonna like 3d printing and after the first print I said "i need a bigger one". After that I got a FlashForge Guider 1, It was more frustrating than anything with awful bed leveling with screws underneath. The head loved to jam and the extruder would have to be disassembled completely. Also I couldn't find any support online from anywhere for that printer, only the guider 2. So a robust community around these printers is also what helped in my decision to buy a prusa. These guys have really listened to the feedback because all of these issues and more have been solved with this printer.

I'm still fine tuning the first layer and I love that you can adjust it on the fly. I've only got 70% alcohol at them moment and it seems to be leaving a film on the steel sheet, I'm gonna have to get some 99.9% when i'm out next. I've got a print that doesn't want to stick and I think that's the issue. I don't want to use gluestick (it got out of hand with the guider) although one was included in the box. does anyone use gulestick? is it easy to clean off?

Re: Just saying hi and a simple question

There is absolutely no shame in using adhesives like gluestick. If it helps and decreases the level of frustration you should definately try it with gluestick. Washing it off under warm water is really easy.

For cleaning, dish washing soap goeas a long way as well. Some people on the forum recommend Dawn, but I regularly just use 3DLac for all my prints and it works perfectly fine without taking much care of cleaning thorougly. From my understanding that's basically the same as gluestick but from a can.

Enjoy your printer!

Here's some copypasta...

Adhesion problems are usually caused by 2 main problems:

  • A dirty PEI print surface. Even if you don't think this is the cause, it's always a good idea to make sure your PEI surface is clean before trying any other fixes. Take it to the kitchen sink and give it a good dunk with Dawn (original formula, no vinegar or hand softener variants) dishwashing soap or your local equivalent (e.g. Fairy in UK). Use a clean paper towel to clean it off, and another to dry it. Avoid using any sponge or cloth that has been in contact with grease. Above all else, avoid touching the PEI print surface. Once it's good and clean, you should be able to use 91%+ isopropyl alcohol between prints, 100% acetone when that fails, and another dunk when acetone fails. Worst-case, use a 3M 7445 ScotchBrite pad or equivalent to give it a very light buff, but only infrequently.

  • If you have not already done so, try using Jeff Jordan's "Life Adjust" procedure for calibrating your Live-Z setting. It is much easier to use and understand than the on-board routine.

    • And above all else, avoid touching the PEI print surface.

    Try those 2 steps. If you're uncertain of the Live-Z results, post pics here of the 75x75 print bottom and you'll get quick help. In general, start high (less negative) and work lower (more negative) in large increments (e.g. 0.1mm) until the filament starts to stick on its own. When it's right, you should be able to gently rub it without it coming loose. Then start lowering (more negative) the level until there are no gaps between layers.
