3d Print Guide_Walk Through

First of all, congratulations to a great machine!
If you have any suggestions to this topic, feel free to send me a PM!

You are new to 3d printing?- Be patient. The whole thing is very complex and just little adjustments will make the difference from failed to pretty prints.

Start with easy, little things to create (1-3hours i would suggest) . Going to print the first time and then getting a 24h print on, maybe failes.

There is a lot to learn, if it didn´t work for a long time, cool off a bit and try some time later.

Today the snapmaker team has a lot to bugfix in the firmware, be sure, using the latest firmware before facing a problem. Also setup instrucions and how to´s on the support site will be important for you!

PLEASE USE IT!
https://snapmaker.com/support

There is also a great WIKI from @Tone, thank you for that!
There are a huge amount of useful links. USE IT!

It would be really nice, just reading your request and answer it. The most time is spent with asking about all neccessary things:

1. FREQUENTLY ASKED QUESTIONS ABOUT YOUR SETUP

Here we go, if you are prepared to print and it sticks so far you will have to face other problems.
DIY means do it yourself, you have to figure out and solve your problems on your own. Sure you could post in the forum but PLEASE give all information which is needed.

Here are some examples:

  • Type of printer
  • Enclosure used?
  • which filament do you use? (There are 1. the kind of filament, 2. the brand, 3. provided Temp. to print) Like i use Janbex PETG transparent, provided printtemp. 190-220°C, btw i print it with 240-250°C, there is less stringing.
  • which slicersoftware do you use? (This means, slicing software where you put your model in, such as Snapmaker Luban, JS, Slic3r, Cura, Simplify3d, …)
  • what settings do you use? (Simple: want to know them all; Advanced: if you know it is a retraction problem, just the relevant data is ok)
    – Quality Profile if using SnapmakerJS or Luban with original settings
    – Flow, if changed
    – Print Temp.
    – Print Temp. first layer
    – Bed Temp.
    – Bed Temp. first layer
    – Layer height
    – Layer width, first layer
    – Wall thickness
    – Top thickness
    – Bottom thickness
    – Infill
    – Print speed, first layer
    – Print speed, outline
    – Print speed, inline
    – Travelspeed
    – Retractin enable
    – Ratraction at next layer
    – Retraction distance
    – Retraction speed
    – Z-Hop when retract
    – Use Skirt, Brim or Raft?
2. DETAILS, PICTURES AND NEEDED DATA

If you need help or just want to know more, please make some screenshots or photo´s and or some searching in the www or forum.
If you are not able to upload provided data, like .stl´s or gcode, upload it to a oneclickhoster, to your google-drive, dropbox, whatever and share it with us. (oneclickhoster, google it :wink: )
– Pictures (sharp and good to see)
– stl´s
– gcode

3. FINETUNE YOUR HARDWARE, ATTENTION

At this point, as a newb, i would not change anything on the hardware setup. My machine ran without any issues for more than 2 years. If you have issues which can´t be solved through software you need to calibrate your hardware.

Here is the support article about bed leveling the Snapmaker Original:
https://support.snapmaker.com/hc/en-us/articles/360015529534-3D-Printing-Leveling-the-Heated-Bed
And articel if it won´t get stick for the Snapmaker Original:
https://support.snapmaker.com/hc/en-us/articles/360013696613-What-should-I-do-if-the-first-layer-does-not-stick-to-the-heated-bed-

There are several threads on the forum (and they are not finished yet?) about bedleveling the SM2.0:

Check Level Hot.gcode

How to do a larger than 3 x 3 matrix level

On achieving a perfect level

4. FINETUNE YOUR SOFTWARE SETTINGS TEST-SECTION

There are several 3d printer test´s on thingiverse or where else you get your .stl´s from.

Here are a few to check your settings condition: (Every filament may need a bit other settings!)

5. FAILURE GUIDES

Hey, so good so far.
There comes something out but it´s not perfect?

Check following failure guides to face your problems (or search the www for videos :wink: :

https://www.simplify3d.com/support/print-quality-troubleshooting/

https://rigid.ink/pages/ultimate-troubleshooting-guide

https://all3dp.com/1/common-3d-printing-problems-troubleshooting-3d-printer-issues/

6. MARLIN AND THE TERMINAL

From time to time you will need some response from the printer.
In this case you have to connect it through USB to your computer.
Marlin is the program language which is the machine running, saying in gcode go to x5 y5 and make this and this.
https://marlinfw.org/meta/gcode/

Attention, Snapmaker doesn´t use all of the marlin gcode commands and even has made some own things.
Official doc about gcode´s used at snapmaker original:
https://docs.google.com/spreadsheets/d/1qDBZTEdHPO59p7PcCulKvBOAjFI-U3O2RyzXJf3Rx6Q/edit#gid=0

If you enter a M503 then you can view your current system settings:(unfortunately Snapmaker Luban supports no copy and paste of the terminal yet)

If you update your firmware your edit will be lost.

7. FINETUNE YOUR SYSTEMSETTINGS

If you are at this point, be sure to know what you do. There is no guarantee if you damage your machine! Copy your original Data of M503 response and save it to get easily back!
There are a huge amount of tutorials out there in the web.

Normally i would suggest you not to change any settings if there is no problem.

M303 PID AUTOTUNING

If you want to pid tune, you should generally think about which sort of filament do you take the most of your prints. I´m using the most of the time PLA at about 210°C with no printpartcooler.

https://marlinfw.org/docs/gcode/M303.html

NOZZLE PID AUTOTUNE
If you use the most of the time a printpartcooler i suggest you to run the fan at 100% for pid tuning.

For running the Partcoolerfan with 100% enter: M106
If you want to turn it off again enter: M107

Enter following to the terminal for pid tuning: M303 C10 E0 S210
[M303=PID Tuning] [C10=amount of testing(10times)] [E0=Extruder] [S210=Temperature]
If you have done so, you have to wait a few minutes, till following response comes (Your values will be different!):

Recv: Classic PID
Recv: Kp: 9.06
Recv: Ki: 1.57
Recv: Kd: 13.05
Recv: PID Autotune finished! Put the last Kp, Ki and Kd constants from below into Configuration.h

Now you see my new P9.06 I1.57 D13.05 values.

To write it to the machine we enter: M301 P9.06 I1.57 D13.05 E0
Now you have to save your configuration entering: M500

BED PID AUTOTUNE
this is currently not available, you would have to edit the firmware configuration.

EXTRUDER CALIBRATION

If you ran into extrusion issues like its permanently over/underextruding you should have a look at your extrusion settings.

If you enter M503 in the terminal you would find following line:
Recv: echo:Steps per unit:
Recv: echo: M92 X400.00 Y400.00 Z400.00 E92.60
[E92.60 is your extrusion factor]

Now you have to mark the filament 120mm over the entry of the print head.

Give the nozzle some heat (edit the S210 to your needed value!) entering: M104 S210
[M104=Set Nozzle Temp] [S190=Temperature set to 210°C]

Set the extruder to relative mode entering: M83
Now, if the printhead is hot, we want to extrude 100mm of filament entering: G1 E100 F100
[G1=linear move] [E100=extrude 100mm] [F100=speed/min this will take a while]

At the end of extruding, you will see the mark is “near” over the printheadentry now.
If you messure from the entry to your mark 20mm, everything is great.
If you messure just 10mm, it´s overextruding (this means there comes too much out)
If you messure 30mm, it´s underextruding.

Now we have to set it up.- We know the old value, in my case E92.60
For this example we messured the mark 15mm over the entry.

Now we have to calculate:
[marked] - [messured] = [extruded]
120mm - 15mm = 105mm

[old E steps/mm] x [Old 100mm] = [old steps taken]
92.6steps/mm x 100mm = 9260steps

[old steps taken] / [extruded] = [new E steps/mm]
9260steps / 105mm = 88.19steps/mm

Now we have to send the new value of E to the machine entering: M92 E88.19
Save it again with: M500

Here is a guide this will help you, if needed:
https://all3dp.com/2/extruder-calibration-6-easy-steps-2/

VIRTUAL BED LEVEL **Snapmaker Original**

If your Touchscreen is broken on your Snapmaker Original you could level your bed manually.

ATTENTION, THIS IS REALLY TRICKY AND YOU COULD DESTROY YOUR MACHINE!
I GUARANTEE FOR NOTHING, ITS ON YOUR OWN RISK!!!
BE SURE TO UNDERSTAND WHAT HAPPENS!

In the M503 you will find these lines:

Recv: Mesh bed leveling:

M421 X5.00 Y5.00 Z0.25
M421 X120.00 Y5.00 Z-0.50
M421 X5.00 Y120.00 Z0.00
M421 X120.00 Y120.00 Z-0.55

These lines are my Z-Offsets. It is not that easy to edit, like write the same with difference in Z.

There are 4 calibration Points, X5Y5; X120Y5; X5Y120; X120Y120.

FIRST MOVE:
First of all, we have to drive to the Homeposition, entering: G28
START:
Now the printhead to the needed position, entering: G0 X5 Y5 Z0.6
Now we lower the head till the paper sticks, using: Z0.5
Now we lower the head till the paper sticks, using: Z0.4
Now we lower the head till the paper sticks, using: Z0.3

OK, Position is great, the last position was “Z0.15”, write it down. X5 Y5 Z0.15, 1st point check.

ATTENTION, now up the head, entering: Z0.6
This is to do an all 4 points, go back to START and enter the next calibration point!

After having all points we have to write it to the firmware:

X5 Y5 Z0.15 : calibrate this position to Z0.15, entering: G29 S3 X1 Y1 Z0.15
X120 Y5 Z0.6 : calibrate this position to Z0.6, entering: G29 S3 X2 Y1 Z0.6
X5 Y120 Z0.7 : calibrate this position to Z0.7, entering: G29 S3 X1 Y2 Z0.7
X120 Y120 Z0.8 : calibrate this position to Z0.8, entering: G29 S3 X2 Y2 Z0.8

After this we have to save our values entering: M500
Control your inputs using M503 or G29S0 to see if it is the same on your paper.
ATTENTION AGAIN, YOUR MACHINE COULD BE DESTROYED AT YOUR NEXT PRINT

8. REPAIR CORNER

Be sure you know what to do, if you are not, get in touch to the support.
I see no problem opening the printhead to change the nozzle.- This is part of the product, but if you damage the pcb in the printhead this would harm your warranty.
Ultimately, i think, it´s a DIY machine, you could repair and service yourself, if you are able to.

1. Dimensional Accuracy

To assess dimensional accuracy, measure each tier of the dimensional accuracy stack and record the absolute different between the target and the measured dimensions in a table.

  • Record a “1” if the magnitude of the overall average error is greater than 0.40mm.
  • Record a “2” if the magnitude of the overall average error is between 0.31 and 0.40mm.
  • Record a “3” if the magnitude of the overall average error is between 0.21 and 0.30mm.
  • Record a “4” if the magnitude of the overall average error is 0.11 and 0.20mm.
  • Record a “5” if the magnitude of the overall average error is between 0.0 and 0.10mm.

Snapmaker A150 earned a score of 5 for this test.

2. Fine Flow Control

Using a pair of calipers, measure the height of the shortest spire on the top of the test print. Visually inspect for threads of material connecting the spires. Measure the shortest spire.

  • If the spires are less than 30mm long, assign a 0.
  • If the spires are greater than 30mm, but there is stringing between them, assign a 2.5.
  • If the spires are greater than 30mm long and there is no stringing between them, assign a 5.

Snapmaker A150 earned a score of 4 for this test.

3. Fine Negative Features

Attempt to remove all the pins from their holes using fingers (no tools).

  • Record a “0” if no pins can be removed.
  • Record a “1” if 1 pin can be removed.
  • Record a “2” if 2 pins can be removed.
  • Record a “3” if 3 pins can be removed.
  • Record a “4” if 4 pins can be removed.
  • Record a “5” if all pins can be removed.

Four pins were removable from the test print. But the pin with the smallest tolerance failed. For this test, the Snapmaker A150 earned a score of 4.

4. Overhangs

Inspect the overhang surfaces.

  • Record a “1” if the printer compiled the geometry but dropped loops and infill on the 15, 20, and 30 degree overhangs.
  • Record a “3” if only the 15 and 20 degree surfaces differ from the 45 degree overhang.
  • Record a “4” if only the 15 degree overhang differs from the 45 degree overhang.
  • Record a “5” if there the surface finish between all four overhang surfaces is equivalent.

Snapmaker A150 earned a score of 3 or 4 for this test.

5. Bridging

Inspect for contact between bridges and the surface beneath each.

  • Record a “1” if more than 3 are in contact with the surfaces beneath them.
  • Record a “2” if 3 bridges contact the surfaces beneath them.
  • Record a “3” if 2 bridges contact the surfaces beneath them.
  • Record a “4” if 1 bridge contacts the surface beneath it.
  • Record a “5” if no bridges contact the surfaces beneath them.

For this test, there are 3 bridges contact the surfaces beneath them. So Snapmaker A150 earned a score of 2.

6. XY Resonance

Visually inspect the X and Y ringing features, illuminating the test print from the side to highlight any ringing captured in the print.

If rippling in the X or Y axis can be observed at or past three hash marks, record a “0”, otherwise, record a “2.5”.

Snapmaker A150 earned a score of 2.5 for this test.

7. Z-axis alignment

If a layer registration effect with a period equal to that of the leadscrew is visible on the pillar supporting the fine positive features test, record “0,” otherwise, record “2.5.”

You can check out the test result in the video above, from 01:00 to 01:07. There’s no periodic ripple in Z-axis. The layers are stacked properly with the same layer height. So Snapmaker A150 earned a score of 2.5 for this test.

Scoring

Sum the results of each section of the test protocol. The highest possible score is 30, indicating a very well-calibrated system.

Here’s a breakdown of Snapmaker A150’s results:

Dimensional Accuracy: 5 of 5 points

Fine Flow Control: 4 of 5 points

Fine Negative Features: 4 of 5 points

Overhangs: 3 of 5 points

Bridging: 2 of 5 points

XY Resonance: 2.5 of 2.5 points

Z-Axis Alignment: 2.5 of 2.5 points

Overall, the A150 prototype scored a total of 23 out of 30 points.
