Your first print

Updated: Jul 15, 2020


You will need a PC, e.g. i3, with at least 4GB of memory and running Java 64 bit. More memory is better, especially when printing big objects, big meaning many faces. If you want to start using the big build plate and place many objects on the build plate you will most likely need to upgrade to 16GB or even 32GB of memory. Imagine 500 rings each with 500 000 faces. That is a lot of faces and will need tons of memory to slice.

Gizmetor uses Java 64 bit. Please remember to install Java 64 bit or you will just get a black screen flashing when you start Gizmetor.

This video will explain the connectors on the printer. Please note, you do need to plug in the HDMI and the middle USB at least for your printer to work. Ofcourse you also need to plug in the power cables and switch on the printer and the projector. If you don't see any lights or hear any fans then things need to be switched on.

This video will show you how a print is done using Gizmetor and GiziPrint. It has some extra background information that isn't in the text.

Extra info before you start

- Please watch the tutorials on our YouTube channel at https://www.youtube.com/c/Gizmo3DPrinters

- Please remember to install Java 64 bit

- We are happy with users tinkering with the machines. If you get stuck we are here for you. The cost of support is $150 per hour or part thereof.

- The only thing you really need to modify at the start is to move the projector assembly up or down and refocus the projector. The projector assembly has a rail brake on each side. We normally use the right side for the closest position the resin and the left side for a second location. If you have automated projector movement you don't need to worry about this.

- You have to plug in the HDMI and USB cable into the printer. HDMI into the bottom input on the front of the machine and USB in the middle. The top USB is used to control the projector(s). That function is not available yet.

- You have to power on the printer for it to work. When you press the button it will feel like it was pushed in. Then it is on. If you don't hear the fan in the back, then the printer doesn't have power. The on/off switch will show bright blue if it has power from the DC input. If it only has power from USB it will show a dim blue light and the fan might turn very slowly.

- You have to power on the projector for the printer to work. If you power on the projector it could burn the resin so it is always good to cover the resin before you start printing.

- You have to fill the vat up to the overflow with resin. Always wear protection. Many companies recommend protective glasses and gloves.

- The PC that is connected to the printer should have a black background. On Windows 10 the toolbar will display on the second monitor. You need to disable the toolbar. Just search on Google how to do it.

- You need to disable any power saving or screen savers on the PC that is connected to the printer.

- We recommend that you do not use the PC that is connected to the printer to do any work on while it is printing.

- If you decide to modify the config files or startup files or anything in the software and you can't get things to work again. We are here for you to help you get up and running again.

Install Java 8 64-bit from

https://jdk8.java.net/download.html Select the 64 bit option under JDK. If you have a version of Java installed already, the new installation will override the old with the latest version.

After installing Java, open a command prompt and execute the command java -version

(To open command prompt on a Windows PC, press the Windows button and type "cmd")

You should see something like the text below. Make sure it says 64-bit

Java version "1.8.0_102-ea" or higher. Java(TM) SE Runtime Environment (build 1.8.0_76-ea-b04) Java HotSpot(TM) 64-Bit Server VM (build 25.76-b04, mixed mode)

Install Gizmetor by running

If you buy a printer from us we will send you the link to download the software. Once downloaded, copy the contents at the link to C:temp (create a temp folder in C: if you don't have one) directory on your computer. Double click on setup.exe to run it. Please remember to install Java 64 bit.

Run Gizmetor

Open Windows Explorer.

Go to the installation directory.

The most likely directory will be C:\Gizmo3DPrinters if you installed it into the default directory.

Double click on Gizmetor or GizmetorNoUpdate.

When clicking on Gizmetor it will execute a bat file in the directory C:\Gizmo3DPrinters\bat that will look for an update of the software and then start Gizmetor.

If you choose to execute GizmetorNoUpdate it will not try to connect to the internet to check for updates.

All the bat files that run Gizmetor are located in C:\Gizmo3DPrinters\bat. If Gizmetor doesn't start and it has the error that you don't have enough memory on your PC, you can edit the correct bat file and change the memory required.

Select a printer and material

When Gizmetor starts it will display a dialog box containing a list of printers and materials that you can choose from. If your printer or material is not in the list you will be able to manually add it by following a future tutorial.

For now select one of the printers in the drop down and a material. It doesn't really matter which one you choose in this tutorial.

Add From File System

Select an STL file from the file system by clicking on the "Add From File System" label at the top left of the screen.

Go to a directory that contains STL files and open one.

Gizmetor will load the STL and create the object in the 3D world.

Start slicing

Start the slicing workflow by clicking on the "Slice All" label at the top right of the screen. The Print Settings screen will open.

Print Settings

The Print Settings screen will populate the Filename field with the names of the objects in the 3D world. It has a limit of 200 characters for the name. You can change the name yourself if you want to.

Print Quality

Changing the print quality will change the Z layer height. Medium is set to 50 micron and is a good default layer height to print with. Many resins can print at 50 micron Z.

Different resins will have different maximum and minimum layer height. For instance, the jewellery resin from Vitang prints well between 10 micron and 30 micron. The Deep Black resin from FunToDo prints well at 50 micron. 50 is a good average if you are unsure what value to type in.

Profile

The list of profiles in the drop down is read from the profiles associated with the material. You can add more profiles by going to the Profile manager tab on the left side of Gizmetor. The profile will give you defaults values to print with. These values can then be changed in the Override manager.

Layer height

When you change the Print Quality drop down this value will also change. You can also enter your own value in the field.

Solid (checkbox)

Checking the checkbox will display the Solid settings. Unchecking the checkbox will display the Hollow settings.

Solid (checked)

Solid wall thickness

We normally don't change the value from 0.05. This will make the line around layers thicker. It can be used to close gaps.

Wall margin

This is mostly used when printing jewellery. This will create a red line around a layer. It opens up gaps. This can be used to compensate for bleed.

Solid (unchecked)

Hollow wall thickness

This will make the lines thicker or thinner of the layer. 0.3 is a good starting value.

Infill width

The default width for the honeycomb infill. Smaller will use more memory and cause more surface tension and more blow-out. Between 4 and 8 seems to be a good value.

Infill height

The default height for the honeycomb infill. Smaller will use more memory and cause more surface tension and more blow-out. Between 4 and 8 seems to be a good value.

Infill wall thickness

The thickness of the honeycomb. The default value of 0.08 seems to work well. Bigger values will make the honeycomb thicker and stronger, but it will cause problems with continuous printing and blow-out. If the honeycomb is thicker than the outer walls the resin will rather go through the outer wall than through the honeycomb

Click on Next to show the Preview Manager

Preview Manager

Features of the Preview Manager includes the Override Manager and the Support Manager.

Override Manager

The override manager allows you to override many settings that are related to the print. For this tutorial delete all overrides if there are any in the list.

Support Manager

Still a work in progress. When it works you will be able to add supports in the 2D view.

True View

When clicking True View it will display the layer as if it was being displayed via the projector using the same scaling and same infill pattern. You can slide through the bar at the top of the screen to see the different layers of your object.

Click Next go to to the Slicing screen

Slicing

The slicing screen is used to create slices of the 3D objects.

Package Only

If you drag a .gizmo file into the 3D world the contents of the file will be extracted to the temp directory. If you then only change overrides in the Override Manager all you need to do is then click Package Only on this screen. The Package Only will create a new .gizmo file containing all the files in the temp directory. It will not slice again if slicing is required. This is a quick and easy way to change overrides.

Slice and Package

The Slice and Package button will generate slices only if it detects that continuous printing has been enabled and it will only generate slices for those layers that need to be printed using continuous printing. The rest of the slices will be generated while printing. This could cause issues for extremely large objects that could take very long to slice per layer. In the future it will be possible to override this function by forcing the Slice and Package button to generate slices for each layer.

Force PNG generation

We normally select Force PNG generation. This will create a PNG file for each layer. If you don't then that work will be done while printing. If the PC that is connected to the printer isn't powerful enough to slice fast enough you will run into issues. If you enabled continuous printing in the override manager then the layers that need to be printed continuously will be generated automatically, because they have to display just too fast to do it while printing.

Click on the Slice and Package button. Gizmetor should run through all the layers very quickly and then generate a .gizmo file. It will combine all the objects in the 3D world into a single STL file and include that in the .gizmo file.

Now switch on your projector/s with the remote while holding a piece of paper or your hand under the lens to block any light from the projector shining onto your resin - block the light until you are able to project any image from the projector in red (explained later in t
