Affiliate Disclosure & Transparency Statement

Operating with total transparency is essential when analyzing mechanical components and upgrade kits for motion systems. In accordance with Federal Trade Commission (FTC) guidelines, this disclosure outlines how 3D Printer CoreXY Upgrade Kits & Extruders earns revenue through affiliate marketing arrangements, the scope of our evaluative process, and how we protect editorial objectivity.

Commercial Compensation and Affiliate Links

Some of the outbound links published on this website are affiliate links. If you follow one of these links to a third-party vendor or online marketplace and finalize a purchase, we may receive an affiliate commission from the retailer. This transaction occurs at zero additional cost to you; the retail price, terms, and warranties remain identical whether you use our tracking links or navigate directly to the vendor.

These referral commissions support the operational expenses of running this reference platform, covering server infrastructure, technical research tools, and site maintenance.

Editorial Independence and Analytical Methodology

Our editorial team maintains complete autonomy over all published recommendations, kit comparisons, and component breakdowns. Affiliate partnerships do not determine which products we evaluate, nor do commercial arrangements influence our technical assessments.

Our evaluations compare published specifications and current listings across multiple sources; we do not conduct hands-on testing. Instead, our desk-based research evaluates technical documentation, mechanical drawings, user manuals, and marketplace availability:

• Julian Vance (Kinematics & Frame Conversion Editor): Analyzes linear rail dimensional tolerances, CoreXY belt path geometries, and frame squaring requirements across published mechanical schematics.
• Clara Lindqvist (Extruder & Toolhead Hardware Editor): Evaluates dual-drive gear reduction ratios, claimed toolhead weight metrics, and published stepper motor torque curves.
• Marcus Sterling (BOM Completeness & Integration Editor): Audits bill of materials (BOM) inventories, cross-references fastener specifications, and tracks lead screw pitch data from manufacturer manifests.

Affiliate Programs Utilized

We participate in several established affiliate programs designed to provide a means for websites to earn referral fees. These include the Amazon Services LLC Associates Program, specialized additive manufacturing component retailers, and direct hardware distribution networks. We do not accept paid placements, sponsored product reviews, or pre-written promotional copy from manufacturers seeking biased coverage.

Reader Verification and Purchase Responsibility

Upgrading a bed-slinger to a CoreXY motion system or mounting an aftermarket high-flow extruder requires exact mechanical and electrical compatibility. While we make every effort to maintain up-to-date information regarding component tolerances and hardware revisions, manufacturers frequently alter kit contents, mounting hole spacing, and firmware requirements without prior notice.

We strongly urge all builders to cross-check frame dimensions, power supply voltages, and motherboard pinouts directly with the merchant before finalizing any hardware purchase.
