FAQ for choosing and using a CzRobotics system

Choose the machine from the useful sprayed area, not from the outer frame size. Singular is the compact base machine, Singular L adds length, Singular X adds width, and Singular XL gives both more length and more width for larger fixtures or future expansion.

A complete machine includes the selected Singular platform, the selected head system, the USB G-code controller, and a 110-240 V power adapter. Options such as a heated plate, Tilt, rotary table, external control unit, or special fixtures are added only when the workflow needs them.

Smooth Head is the standard single-nozzle head with precise needle opening controlled as the A axis. Tricolor uses three independently controlled nozzles for switching between reservoirs. Hexacolor is the multi-nozzle route for demanding multi-feed applications, but it is physically larger and needs a more specific setup discussion.

No. The Tilt system is compatible only with the Smooth Head. Tricolor and Hexacolor heads are too large for this function. Tilt works in one direction, left to right on the X axis, with an angle range of about +/-45 degrees.

Yes. A 3-nozzle head or the Tilt mechanism needs extra physical space, so the useful working area is naturally reduced, mainly in the X axis. If all nozzles must reach the same point, this must be included in the machine choice and fixture layout.

Yes, as a custom accessory. We build the rotary table for the application and integrate it directly into the machine control and G-code workflow. Synchronized nozzle movement and object rotation in one program is usually more precise and reliable than running an external third-party rotary table separately.

The heated plate is useful when drying speed, layer formation, or substrate temperature affects the result. It is a popular upgrade for lab work with drying-sensitive coatings, repeated samples, or processes where a more stable thermal condition improves repeatability.

No. For G-code generation we provide a CZR plugin for Inkscape, a free vector editor. For sending prepared G-code to the machine we usually recommend Candle for simple operation or UGS Platform for more advanced control.

The plugin helps turn vector geometry into machine-ready path logic and G-code for the CNC airbrush workflow. It does not remove the need to tune the real spray process: speed, distance, nozzle opening, pressure, material behavior, and substrate absorption still decide the final result.

The standard machine includes a USB G-code controller. It interprets prepared G-code and sends signals to the stepper motors. The basic system controls X, Y, Z, and the A axis for smooth needle opening, while more complex setups can use additional axes.

Yes. For production-style operation we can supply an external offline controller with LCD display and SD card. It lets the operator run prepared programs without keeping a laboratory computer connected during each cycle.

If you use the external offline controller through the serial connection, do not connect the USB cable from the machine to a PC at the same time. Use only one control connection to the machine at once.

Usually yes for the Smooth Head. It can be connected as a 4th axis in your control system, with the motor wired to a stepper driver and the integrated limit switch wired for homing. If your system cannot drive a 4th motor, we can discuss a dedicated interface board.

This public FAQ explains the decision logic and basic workflow. Detailed downloads such as plugin files, driver links, exact installation steps, and owner-level operating notes are best handled as guided support material for customers who are setting up or already running a CzRobotics system.

Simple standard products can be ordered through the shop. For configured machines or custom accessories, the process starts with your request, then we confirm the configuration, issue a quotation or proforma invoice, and start the build after approval and payment.

For custom complete machines, the standard build time is 4 to 6 weeks from order confirmation and payment. Stocked parts and replacement components are usually shipped within 5 working days.

Yes. We ship worldwide, typically by courier service. For companies, universities, and laboratories, we can handle the usual B2B details such as bank transfer, invoice data, VAT information, customs details, and delivery contacts.

Use the shop when the configuration is standard and the product page clearly matches your need. Request a quote when the setup includes a rotary table, unusual fixtures, circulation, integration work, special tests, or anything where the application decides the machine.

The most useful request describes the material or liquid, target substrate, sprayed area, required repeatability, whether the part is flat or needs rotation/tilt, and where the current manual or production process starts to fail. Photos, drawings, sample dimensions, and safety constraints help us answer faster.

Yes, this is available as an additional evaluation step for unusual or uncertain applications. Most projects begin with the customer’s existing process, application details, and a configuration discussion. When direct evidence is useful, you can send samples and material for a practical spray test.

A liquid that already sprays reliably through a manual airbrush has a very high probability of working in our CNC Airbrush with a comparable nozzle. Nozzle diameter, viscosity, particle distribution and agglomerates, drying behavior, pressure, and cleaning routine still influence the result.

Airbrush spraying creates a naturally soft edge because the liquid is carried by air. The visible edge depends on nozzle size, distance, pressure, speed, viscosity, and substrate absorption. Porous or absorbent materials often show less visible overspray than smooth non-absorbing surfaces.

Common airbrush nozzle sizes are around 0.2, 0.3, and 0.5 mm, and a larger 0.8 mm option is in preparation. Smaller nozzles are useful for fine work and low amounts, while larger nozzles tolerate different flow and particle conditions. The right choice depends on liquid behavior, required dose, and cleaning routine.

We strongly discourage fast-drying nitro paints for normal use. They dry quickly on the needle and inside the nozzle, which leads to frequent clogging. If your material dries aggressively, the cleaning routine and nozzle choice must be discussed before ordering.

The safest routine is to flush the liquid path with a suitable cleaner immediately after use and before the material dries. Needles and nozzles are service parts, so they can be cleaned or replaced when needed, but the exact cleaning liquid must match the material you spray.

For suspensions and media that settle in the reservoir, we can prepare a custom head modification for a circulation loop with a pump. The goal is to keep the medium moving between reservoir and head so sedimentation does not break the spraying process.

Yes. Nozzles, needles, heads, fittings, electronics, cables, and other replacement parts can be supplied separately. This matters because repeatable spraying depends on keeping the fluid path, needle, nozzle, and control electronics in good condition.

No, we do not manufacture ventilated cabinets. We recommend using a suitable spray booth or chemical fume hood from a specialized supplier. For volatile or flammable substances, the user is responsible for following ATEX requirements and providing extraction that prevents an explosive mixture from forming.
