3D printer motherboard enquiries and custom controller development for additive manufacturing and motion control applications.
Discuss this projectSmartPrintCoreH7x: a documented open-source design
SmartPrintCoreH7x is published by Boltz R&D, with a public fork under Triterria. Review the design files and firmware configuration for the board revision you intend to use, or discuss a quotation for a board or custom controller. The source links below make the engineering documentation available before an enquiry.
Find the right controller for your printer
A mainboard enquiry should start with the machine configuration. Share the motion system, motor and driver requirements, heaters, sensors, fans and host interface. Tell us whether you need a board for an existing printer, a new machine design or an OEM integration.
Mainboards and custom electronics
Our engineering portfolio includes 3D printer motherboards, stepper driver platforms and motion control electronics. Discuss the available board options or a custom hardware and firmware scope with our team. Model, board revision, firmware compatibility and the required accessory set are confirmed during the enquiry.
Scope integration before procurement
Bring a wiring diagram or interface list where available. A useful discussion covers power inputs, motor connections, thermal sensing, output loads, enclosure space and the software environment. Confirm the complete configuration rather than assuming boards with similar connectors are interchangeable.
Request availability or a development quotation
Share the required quantity, destination and target date. We can discuss an existing board enquiry, adaptation to a machine or a new controller development scope. Pricing, supply availability, lead time and support are confirmed for the specific enquiry.
