Hardware FAQ

Hardware


What are the overall weight and dimensions of the unit?

The unit weighs about 50 lbs/23 kg. It is recommended to unbox it with two people, even though our shipping box is easy to unpack. The dimensions of the Developer's kit are roughly 18.5" (front) x 24" (to back) x 16" (top to bottom).

Will the unit be CE marked as per EU legislation?

Yes.

Does the unit have safety locks installed whilst the unit is in operation?

The unit has an acrylic door over/hood, but there is no lock in the current generation. The hood can be opened and closed without stopping the printer for convenience. There are no key locks or e-stops on our latest generation.

With the purchase of the equipment does a full supply of technical literature come with the order, covering schematics of electrical drawings, installation and operating guides, periodic maintenance procedures and 'Health and safety' warnings?

The printer will comes with this online documentation that covers setup and operation of the printer including hardware, support, and materials. Also maintenance, troubleshooting, health & safety, and materials. We don’t include electrical or mechanical designs.

Do have have a catalogue of spare parts and costs?

We do offer consumables and very basic repair parts (i.e. replacement wiping station kits, etc) via our store which you can buy consumables from (if you own a printer).

What is the build volume of the printer?

It is currently 150 mm (x-axis) x 150 mm (y-axis) x 100 mm (z-axis), or 5.906" x 5.906" x 3.94". However, when printing multi-materials, some calibration prints as well as the wiping tower may be present along with your print job, taking up a small bit of space.

What are the specifications for the Voxel8 Developer's Kit printer?

There are the most current printer specifications.

What is the X-Y resolution of the printer?

At this time of writing, the resolution is 15 microns.

What is the layer accuracy of the printer?

200 microns with the standard shipping nozzle on the Developer's Kit printer.

What is the minimum pitch size of electrical components that can be interconnected?

Currently, the finest pitch size is 0.8 mm. This is the pitch size for TQFP chip packages. We are currently investigating ways to get lower than this value, reliably.

Will the cartridge system allow me to use new materials as they are released?

New matrix materials will be released in cartridges that are dispensed pneumatically. Each cartridge is held in place via magnetically assisted kinematic coupling. Cartridges can be swapped out in seconds from the cartridge holder assembly.

How does the printer switch between the two types of printed materials?

The printer prints layer-by-layer and alternates between matrix and conductor, as needed. The printer has wiping and purging stations for each head to ensure that the tips remain clean and primed.

Can the extrusion pressure be changed?

Yes, the extrusion pressure is adjustable.

What is the largest part that the Developer’s Kit can make?

The printer has a build volume of 5.906” x 5.906” x 3.94” (150 mm x 150mm x 100 mm). However some space is taken up by the wiping tower during multi-material prints, so it is a bit less.

Which gantry system is being used?

The Developer's Kit is using a novel implementation of CoreXY.

⇧ Back to Top

Does the printer have a heated build plate/bed?

Yes. We have printed ABS on our machine, but for multi-material prints we recommend using the supplied PLA filament we provide with the conductive silver ink. For the PLA we ship you don't normally need to heat the build plate.

⇧ Back to Top

Is the printer capable of auto-leveling?

Yes. The printer will be able to measure any tilt present in the bed and compensate for it in software. This is possible, because our conductive ink head is capable of moving in Z-axis independently of the matrix material head.

⇧ Back to Top

What are the power requirements of the Voxel8 Printer?

6A @ 120VAC/240VAC. The Printer connects to power through a standard 120/240 AC outlet via 3 prong power plug. Additionally, internationally shipped machines should come with converter for your power input standard. The Developer's Kit has an auto-switching power supply from 120V to 220V.

NOTE: The machine can draw 10 amps at certain print intervals.

⇧ Back to Top

Is the build plate on your printer a consumable item?

Our build plate is constructed of rigid aluminum and will last for hundreds, if not thousands of prints (if properly cared for).Over time a build plate may exhibit signs of wear and tear such as scratches even when painter's tape is applied to the surface.

Deposit Pre-orders will come with a single build plate, while "Get it First" orders have two build plates in the shipping box. If you require another build plate in addition to these, you can order another one from us from the Voxel8 store.
NOTE: You will need to re-calibrate the machine after replacing a build plate using the alignment feature.

I get a machine state error: "MAXTEMP triggered, system stopped! Heater_ID: 0", Error: Thermal Runaway System stopped!, or a "cartridge not found" error. What does this mean, and how do I address it?

The MAXTEMP error is a legacy error, but you may encounter a similar "Cartridge not found" error. Essentially they can mean the same thing, which is that either the FFF or silver cartridge is not properly seated and cannot communicate with the Printer software. In the older case the machine would report a MAXTEMP error with the FFF extruder. Also known as a thermal runaway error.  However, the Developer's Kit will instruct you that the print head cartridge is not inserted with the latest generation.

Troubleshooting:
    1. First, power down the printer and check to see if the pins inside of the empty print heads are free of any debris.

    2. You should then remove and re-insert the print head and see if the problem is fixed. If it is not fixed at that stage, then contact support for further instructions.

I am getting an end stop error on my printer? What can be causing this? How can I fix it?

The optical readers may need to be cleaned out which sense the end stop positions on the Core XY. Use compressed air, and check for anything blocking them. (See pictures 001 and 002 for end stop location).

Picture 001: End stop location from above.

I am experiencing a problem with filament feeding?

A common occurence is stripping and skipping (and especially with non Voxel8 sourced filaments), which we cover in this article.

Where do I find my Developer's Kit Printer Serial Number?

It's printed on a black label on the back of the Voxel8 Developer's Kit machine.

What is the USB port on the back of the Voxel8 Printer for?

It is not meant for customer use. It is only used internally for servicing.

TIP: It is possible to plug in a USB keyboard if you're having issues typing in a Wifi password when configuring a network password for your printer. However, we recommend you do not keep it plugged in. Use the touchscreen interface for navigation purposes.

My heated build plate is not recognized or not being heated, what could be the issue?

There is a potential error where the heated build plate pins get stuck down, or commonly; there is print debris (i.e. thermoplastic) blocking it from making a great connection. The result will either be that the build plate does not heat or the bed is not recognized. Check to make sure your area is clean and that pins are ok. Refer to troubleshooting for other possible explanations.

My silver print head does not seem to be actuating, what can I do?

This could be caused by a mechanical jam or bad software/slice You should refer to troubleshooting, next.

What kind of network connectivity hardware do you have in the machine?

We offer a physical ethernet jack on the back of the printer (i.e. RJ45) along with a provided CAT6 cable. In addition, we also have a built-in WiFi module for wireless setup. For more information, refer to the networking configuration page, or hardware specifications page.
