Frequently Asked Questions - K8200 VELLEMAN

How do I level the print bed on the Velleman K8200?

Use a piece of paper to adjust the bed screws. Home the printer, then adjust each corner so the paper slides with slight friction. Repeat until level.

What filament types can I use?

The K8200 supports PLA and ABS. For ABS, a heated bed upgrade is recommended. Avoid flexible filaments without modifications.

How do I change the filament?

Preheat the extruder to the filament's temperature, then manually feed the new filament while pulling out the old one. Use the 'Change Filament' option in the menu.

How do I calibrate the extruder steps/mm?

Mark the filament, extrude 100 mm, measure the actual amount, then adjust the steps/mm in firmware via formula: (current steps * 100) / actual extruded length.

What is the maximum printing temperature?

The standard hotend reaches 250°C, suitable for PLA, ABS, and PETG. Higher temperatures require an upgraded hotend.

How do I stop a print?

Press the Stop button on the LCD or send an emergency stop command via USB. Always wait for the hotend to cool before handling.

Can I print without a heated bed?

Yes, for PLA. Use painter's tape or glue stick on the glass bed. For ABS, a heated bed is strongly recommended to prevent warping.

How do I update the firmware?

Download the latest Marlin firmware, modify the config files for the K8200, then upload via Arduino IDE connected to the board via USB.

What should I do if the print doesn't stick?

Check bed leveling, clean the bed with isopropyl alcohol, and apply a thin layer of glue stick or hairspray. Also, ensure first layer height is correct.

How to fix clogged nozzle?

Heat the nozzle to 200°C, then use a thin needle to clear the blockage. If clogged, perform a 'cold pull' by heating, cooling, and pulling out the filament.

Important safety instructions

CE conformity information:

The K8200 is a DIY 3D printer kit, it contains all the bits and pieces to construct your own 3D printer but does not contain additional protection.

As it is a kit and not a finished product, compliance with the CE regulations depends on the build-quality; also the following notes must be taken into account.

Electrical safety:

The included power supply meets all the applicable European requirements and bears the CE-mark.

It is protected against overload and short circuit and nothing needs to be modified. The working voltage of the 3D printer is 15Vdc (extra low voltage) and therefore it's outside the scope of the Low voltage directive.

Always unplug before maintenance or modification.

Electromagnetic radiation (EMC):

Conductive EMC towards the public distribution network is not an issue as this is related to the power supply.

Radiated EMC depends substantially on the build quality, it might be required to add shielding but this cannot be predicted.

A built K8200 should comply with EN50081 normation

Mechanical safety and protection:

The 3D printer contains a lot of moving parts, but the force of the stepper motors is too low to cause serious injuries. Nevertheless it is recommended to provide additional protection against mechanical risks.

The easiest way to make your 3D printer “accident proof” is to put it inside a protective enclosure which completely covers the 3D printer – with or without an access door and fume extraction. (numerous designs can be found on the internet)

To make it extra safe a switch which interrupts the power supply of the printer when the enclosure or door is opened can be added. It is also advisable to install an external emergency stop switch, which also cuts off the power supply.

Providing adequate protection is the responsibility of the assembler.

Always cut power before maintenance or modification.

Risk of burns:

There is a potential risk of burns as the Printer head (extruder) can reach up to 270^irc C.

The use of common sense should be sufficient to prevent burns, but in some environments it is highly recommended to provide additional protection. (see § Mechanical safety and protection)

The max. temperature of the heated bed is 60^irc C, this is below the 1 min. burn threshold for plastic surfaces according to CENELEC Guide 29. Normal reflexes prevent long contact periods with hot surfaces

Always let the 3D printer cool down for 60 min. before maintenance or modification.

Health:

This printer is designed for use with PLA and ABS filament (MSDS for the Velleman filament is available).

PLA: is a safe and non-toxic material, there are no known health safety risks when used in 3D printers.

ABS: when printing with ABS there is a distinctive ‘burned plastic’ smell. This is quite normal but it may also cause headaches, respiratory- and eye irritation with sensitive people (although it is not toxic)

Only use the printer in a well-ventilated area, if printing with ABS it is advisable to add a fume hood (with active carbon filtering for ductless extraction). Fume extraction is mandatory for use in offices, classrooms and alike.

Never burn printer filament, toxic gasses and vapors will be generated if exposed to fire.

General safety information:

The 3D printer is not intended for use by persons (including children) with reduced physical, or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning the use of the appliance by a person responsible for their safety

Children should be supervised to ensure that they do not play with the appliance.
