Things to Check:
Connect via USB? Yes
SD card work? No card was provided
Are there any skipped steps? No
Does the x-axis level? Yes, except for after I did the Z-brake test. Right side did not fully level, off by about 5mm
Does it probe correctly? Yes
Does the LCD work? Yes
Does the z-axis bind at all? No
Does it wipe correctly? Yes
Is the skirt consistent across the bed? Yes
Does the toolhead bump only once while homing? Yes
Any temperature errors? No
Printer off, is z-brake engaged? No
Printer on, is z-brake engaged? Yes
Any belts rubbing? Left z belt slightly rubbing against x-end motor mount-does not seem to affect print
Any rubbing cables? No
Has anything come loose? LCD screen has some play mounted to the frame
Does the filament feed properly? Had clog twice, profile setting and extruder thumb screw possibly not tight enough
Does the heatsink fan run? Yes
Are the belts remaining tight? Yes

General feed back:
During setting up the printer the first thing I noticed was that the spool arm fits too tight. Had to use some force to fold it most of the way up. Did not want to snap it so did not get the spool arm all the way into position. LCD screen also was loose against the frame. Would wobble while inserting SD card or pushing in the LCD controller dial. Switching out the filament was smooth after preheating the toolhead. I am impressed with how quiet the Aero toolhead, as well as the whole printer is, compared to previous versions. Can hardly tell it is running unless you are right next to the printer. Axises have quick and quiet movement, most noticing improvement in the Z axis travel speeds. Quicker movements and probing resulted in noticeable reduction in print start up time. I did manage to get the auto-leveling to fail once after a z-brake test, but was not able to reproduce with further printing. The left z belt was rubbing along the x-end motor mount slightly. This did not seem to affect any prints, but over time could possibly wear on the belt. The new fan shroud design blocks the majority of visibility of the bed, making it harder checking prints when they initially start; especially if the print is small.

Hibiscus Testing:
Cory Lynch
Hibiscus Einsy 10
OS: Windows 8.1 Pro
Filament: Verbatim PLA

Initial Start: Saturday 3/31/18 11:30am

Things to Check:
Connect via USB? No, My laptop could not run Cura 3.2, I loaded all files in Cura v21.04 that was on my laptop. Selected the filament being used, set the settings, and saved the G-code to the SD card provided. Ran all test prints via SD Card. Whipping, probing, and print all looked good.
SD card work? Yes.
Are there any skipped steps? No
Does the x-axis level? Yes
Does it probe correctly? Yes
Does the LCD work? Yes
Does the z-axis bind at all? No
Does it wipe correctly? Yes
Is the skirt consistent across the bed? Yes
Does the toolhead bump only once while homing? Yes
Any temperature errors? No
Printer off, is z-brake engaged? No
Printer on, is z-brake engaged? No
Any belts rubbing? Did not see any belts close to rubbing on my machine
Any rubbing cables? No
Has anything come loose? Seemed to be in good condition. LCD screen had a little wobble. seemed okay.
Does the filament feed properly? Had one filament clog, after the first attempt of the skull art. Easy fix after pushing filament through.
Does the heatsink fan run? Yes
Are the belts remaining tight? Yes

I have placed handmade tags on all of the prints that I ran.

General Feed Back:

Although I could not connect the Mini 2 to my laptop, due to lacking the ability to run Cura 3.2, I feel that the LCD Screen worked exceptional. Printing was a breeze, and the quietness of the machine was just awesome. Print time estimates seemed to be very accurate.

I did notice that after a print, whenever the print reaches 99% the timer on the print starts over and records the time of the cool-down. Intentional? So when pulling a completed print off it would say 4m 33 (example) on the LCD screen. Not sure why I need to know how long the cool-down was, would prefer to see the actual print time after completion.

If you have any questions or need anything at all, please let me know.

Feedback: I ran a few egg prints from Thingiverse on their featured page. First few prints went well while running via USB, I ran across one in the set (kraken) that would randomly stop mid print and wouldn't continue until I reset the printer, resulting in a failed piece. This print failed every time at different points in the print, I ran it with the console open and debug messages but no error was logged. I eventually had success once I exported to SD and ran from the LCD, this might be an additional tool to include with the tool-kit, a USB SD card reader and writer for users who do not have the option built into their computer. The LCD button seemed to stick on my machine causing menu navigation to be more difficult than desired, and the spool arm did not raise all the way.

Overall the print quality was great, very little artifacts from mechanical assembly or the hot end. I think a few of the kinks will need to be ironed out for the price to match the ease of use, it is possible my Macbook printing via USB was an isolated issue. I have some .gcode saved to the SD card in the printer, importing the profile from those will give the settings I was using. Let me know if there is any problem finding the same STL to reproduce the error.

Here's the video of my print pausing for a second. It happened both over USB and from SD Card. The other models I printed didn't have this issue, so it may be more of a Cura 3 issue.

This Hibiscus ran great through the middle of the week. Only one issue to report. When turning the printer on and off to check if the z-brake engaged. One time the x-axis was not homing correctly. I thought maybe it was out of level and auto-leveled, which passed, and again bumped a couple times at X-home. This only happened twice and did not repeat. This printer was very quiet. The belted also remained tight, which were checked before starting a print. Nozzle was cleaned well after each wipe. Flipped the wiper pad half way through testing. The Articulated butterfly 1st layer was a issue with the slice. Maybe due to the fact I was unable to download Cura LE due to my video card being out dated. Yet, I had Cura and sliced files with the mini and changed Esteps to 420. I ran a SD card the whole weekend. I was unable to open Cura LE due to my video card being out dated. Yet, I had Cura and sliced files with the mini and changed Esteps to 420. I was able to connect to Cura LE on another computer.

Skyler. Had the einsy 11 printer. Belts needed adjustment when printer was received. X was very loose and the Y and Z were very tight. Adjusted belts and everything ran smoothly. The case fan wasnt moving when i first got the printer. I removed the power box and repaired the fan so it could move freely and quiet. The Lg. Herringbone gear appears to be rubbing on the filament guide. Over all the printer ran fine and the quality of all the prints came out very nice.

@lansky @Megan @eBeardslee @benmalouf

can you please have those that are using the betas at Lago leave any and all feedback here?

lansky added a comment.EditedApr 9 2018, 12:51 PM

Mini Enisey 14 (I've been told this is an Alpha that had Beta modifications made to it, so take this with a grain of salt.)
Firmware 1.1.8.21
Print from SD, print sliced with 3.2.16. SemiFlex Standard.

The issue is inconsistent, but homing and auto leveling will cause the toolhead to grind into the left hand side of the printer without stopping. I tried restarting multiple times, moving the toolhead by hand and then homing again, and sometimes it will correct itself and home correctly. After correcting any homes and auto levels will be alright until the Mini is left off for a long period of time, then it will start again.

Even when the issue corrects the Mini will still run into the left hand side during the auto bed leveling sequence at the start of a print, it will grind for about one second before stopping and continuing with the leveling and print correctly.

Edit: Logan reached out to me and had me loosen, then push the top X smooth rod to the left, which seems to have fixed the issue.

Just walked into my epic fail.

Might need to tweek my hips settings.

@youngmrcarlson I've been having the random pausing like that on my gladiola at work as well. So far I haven't noticed a rhyme or reason to when it happens and they're so few and far between that I don't think I could catch one on video.

General Feedback: I had problems with a clog on the test strip the first night, I spent 45 minutes trying to get out. Nick P. and Dani G. were able to help the following day. I tried again to set up and run it through again. Successfully loaded the new filament and ran the basic tests. Once the first print started, it stopped after 4 layers. I tried to restart and it would no longer extrude. Again spent over 30 minutes trying to remove filament with no luck. Returned the printer without further testing.

In light of photos posted of failures, I was instructed to post a photo of my success:


This is in Village Plastics PLA Yellow. Z-Hop on every retract, acceleration turned WAY down, speed turned down, temp turned down, and an additional dial back of the feed rate on the LCD to 80%. This print took around 27.5 hours to complete. Pictures don't really accentuate how good this looks in person.
Especially when compared to the one printed on default profiles with only Z-hop turned on.

General Feedback: Was printing over the weekend, did like four three hour prints and a five hour print. Really the only thing I noticed is the Z level at the start of some prints. If I do not preemptively Z level it before a print it can either be off on one side (the left, it's always the left that is too low) or the entire Z level is too low to print.

@lansky Any time the steppers are disabled, the printer is turned off, or is disconnected and re-connected, the X-Axis needs re-leveled. There is a button for this in Cura as well as in the Movement menu of the LCD. Best practice is just to do it before each print start.

lansky added a comment.EditedApr 17 2018, 12:35 PM

@logan Yes the "preemptively Z level it before a print" is me using the LCD screen command under movement. Have we considered making it part of the start gcode if we expect it to be on every print?

I guess this close to release it might not be something we want to mess with, but something to consider down the line.

logan added a comment.Apr 17 2018, 1:07 PM

@lansky That was the original idea, but if the printer stays connected, the motors shouldn't turn off unless they're told to, which would then just be an unnecessary step on start gcode if you had just finished a print and are starting a new one. But just FYI TPTB elected to add the button to Cura and the LCD instead.

@logan Well makes sense.

Since starting to print with the beta and Cura 3.2.xx I've noticed that layer seams/start-stop points have been more evident in many prints. The artifacts tend to look like gaps or voids near corners or edges of mechanical parts. The part linked internally below prints great, except for those artifacts. It looks to me like the print head is not properly priming before starting those perimeter paths.

I've seen this primarily with the standard PolyLite profile, but also using the Fast profile. The artifacts are present, but less obvious, with the standard nGen profile also. Printing on a different beta unit had the same results.

karrad added a subscriber: anolen.Apr 18 2018, 9:18 AM

Since printing with the Hibiscus, Ive noticed it being pretty consistent, that the left side of prints (control box side) tend to have more squished layers than the right side of a print. I have leveled the x-axis before every print. I have tested 3 different Mini 2'zs and all seem to be about the same. For example: Flexy Shark I just printed, needed to be broken slightly on the left side to have the movement in the joints, however the far right side of the prints joints were movable straight off the heat bead. Anyone else noticing this?

@clynch Yes, a lot. Please see T2220 and T2427 for more details

@logan Thank you! Much Appreciated!

@clynch yes we have been seeing this on many of the beta units. Currently I belive the skirt needs to be within 100 microns from the highest and lowest points. We are currently looking into this.
