Final bump. This is really cool machine!

Little 1-1/4” x 2-1/4” x 1-1/8” box. Screw post recess is 1/2 way down.

I don’t know… That x-axis waving around in midair like that gives me pause.

I bought a Creality Ender 3 V2 earlier this year for about $50 more than this and it has two supports to keep the x-axis parallel to the print bed. Also, as it is one of the most popular FDM printers, there is a LOT of content online to help a newbie get great prints.

Not trying to sell anyone on the Enver3 V2, just giving a couple of my reasons why I chose it over many similar priced alternatives.

The X axis is very rigid over 6” of thavel

I did notice that there seems to be a specification error. The build area is listed as 4-3/8” square and is actually 155mm/6”! The build area is larger than specification! I measured the physical travel and the software allows positioning (and it prints) in a 6×6x6 volume. The Z axis may also have some extra range that I haven’t checked yet.

Another tip: The print head shroud is large and at the beginning of a print its very hard to see what the print head is doing. A UV flashlight makes the filament & glue glow different colors making it easier to see if the build started properly.

Proper adhesion is key. Too little, the build won’t start, Too much and you get a gooey mess. It also seems to help to let’s the glue dry before building on it. A thin, dry film works best.

I’ve only really had problems with false starts where the adhesion wasn’t right and you wind up with a tangled ball of filament instead of anything useful. Fortunately the extruder doesn’t dump a huge amount of filament in the process. Keep an eye out as it builds the first 1mm or so (four or five slices) and if it doesn’t catch, about the print & try again.

I’ve burned thru about 1/3 of a roll of filament in four days of building.

Everything red was extruded in the above pictures.

3D printers come in handy for a lot of things. They take a lot of tweaking to get them dialed in. I also have a Creality Ender 3 V2. It took me about 6 months to get the hang of it. With each brand, and even color, of filament it seems like you are starting over at first. Keep your bed clean and level, no drafts in the room, your filament dry, and record your settings. In woodworking I thought getting to 1/64 of an inch in accuracy was outstanding. With 3D printing your shooting for 1/100 of a millimeter. When I started I was printing around 25-30 mm/sec to get a good print, now that I understand it and have upgraded my board, cooling fans and ducts, added an auto bed leveler, a camera, a Raspberry Pi with OctoPrint, have a filament heater/dryer, etc. I can print at 100 mm/sec all day long without any problems and my prints are as smooth as a baby’s butt. By the way, if you have a Microcenter near you they have the Ender 3 Pro on sale all the time for $99.00, that’s $200 off. You have to sign up to be on their email list to get the coupon code. You can’t reserve it on line, and they won’t ship it. The current offer expires today. The next offer will probably be released tomorrow and will last for two weeks. Creality probably sells more hobby-level 3D printers than all other makers combined.

This one set up and ran out of the box. No tweaking. I’m using the defaults with a 90% infill and the stuff is coming out solid.

You realize verything you see was designed and successfully printed since delivery on sat the 18th & late on the 20th?

There was no tweaking. That’s kinda the point. It was printing 15 minutes after I opened the box. My first bracket design was done in an hour and I’ve got over two dozen printed designs and dozens of copies of some parts. They’re all dead on with no d!cking around other than getting the part started. Bed levelling is automatic.

This is literally sold as “child’s play” for middle school STEM students!

90% infill! I usually print at 10-15% infill. The most I’ve ever done is maybe 20%. The things I’ve printed could probably be run over by s truck without crushing them. I’ve even tried crushing them in a bench vise and they hold up really well. You’ll save filament and a lot of print time if you lower your infill level.

At 15% infill the support cols snapped off the base when I tried to remove it from the build table They were 1/4” dia, 1” tall attached to a 3/8”w x 1/8”thk base. I’m making small, strong things for mounting little sensors and the like.

This is 3/4” dia, 1” tall:

I was fixing to place the order and the sale price disappeared.

Bizarre. A few minutes later, the price went back to the sale price. The filament is 1/2 price, so I bought 4 spools.

It aggravates me that Griz charges me 8% sales tax when the correct tax is 5.5%. I’ve tried in the past to fight that with them with no progress. Meanwhile Alibris.com (a bookseller) fixed it after I complained so I order books from them when possible. Homedepot.com always had the correct rate, but Amazon always has it wrong.

Grizzly filament is no bargain. It’s at Walmart for $15/kilo all day.

The red is slightly translucent and the fab makes it sparkle like 50’s diner red seats. The cam shows it oranger than in life.

Well, I paid $15 for it, so no problem. I got an extra nozzle too. Don’t know if I’ll need it or if I’ll need one for each color.

Now the questions are:
How study are these printed objects?
Are they dimensionally stable, or do they shrink over time.

Anyway I’ve been meaning to buy one of those to play with, so now I have.

I used to work (as a programmer) for a CAD company, and wish I could use 20-year-old software that I well knew. Oh well. I had no problems with Sketchup, but I think it has deteriorated in the latest free version and they work it so you can’t use the old one. I suppose I could write my own CAD but it would take me a year which I don’t have to waste on such adventures. I friend of mine put together a pretty good CAD system in about 3 months working 100 hours a week, but he’s not an average programmer. The company didn’t want him to do that, and sent him home He was supposed to be doing something else. (He was working in Paris.)

The change filament does a good job. PULL as it feeds back. Cut the last 1’ or so off to get rid of rough texture. It came with a small spool of yeccch green for test. No prob changing to red w/o cross contamination.

If it won’t start printing do change filament and try again.

Manually raise Z to 100 mm or so before changing filament. This will let you scrape crud (glue/fil) off the sides. Tip is HOT! DAMHIKT

Actual print area is 6+ X, 5+ Y & 7+ Z.

Spread glue thin, even & let dry before use. Doesn’t need to reapply unless film is gone and build is glassy.

Scrape excess glue threads between runs. Tray pulls forward easily when not printing. Is messy. Glue strands stick. Put paper down under machine.

Use PREHEAT between runs.

USB operation is odd. plugging in USB resets printer. Turn computer first and then printer on & allow to boot. Connect USB & printer will restart & everything should sync. Printing via USB has no run time counter so it looks like nothing is happening. You have to select “Print using USB” and then click the button. Printer bottom line will say “E1 Heating” until head warms and motion begins.

Have fun. Look into TinkerCAD while you wait for delivery – NEVER LOG OUT – it thinks you’re done FOREVER and kills your account – losing all your objects! You have to select DUPLICATE to start a new drawing based on an existing part. Renaming in the GUI does NOT fork the file!

At those small sizes, it is probably more like 100% anyway. I’ve had really good luck using blue masking tape on the bed. It gives it really good adhesion and it’s easier to get off the build plate as well. I buy the widest stuff I can find.

I’ve got a Sainsmart Ender 3 and it required minimal assembly. I haven’t had any calibration issues. As long as I get the build plate level, it performs flawlessly.
