Atomstack Glacier 90W Water-Cooled Diode vs Ortur R2
Technical comparison · Diode laser (405–460 nm)
Glacier 90W Water-Cooled Diode and R2 are not direct competitors: different use classes (F4 vs F2), very different prices (~3.7×). R2 costs less (~€540) and is the entry-level choice; Glacier 90W Water-Cooled Diode offers more capability at a higher price (~€2000). Judge them by budget, not head-to-head.

| Software notes | The system is compatible with leading laser cutting and engraving software, such as LightBurn and LaserGRBL. The machine offers fully offline operation capabilities via its built-in touchscreen display, allowing users to manage jobs locally without the need for a permanently tethered computer during extensive runs. It supports standard G-code files and can be expanded with additional modules, such as the infrared laser for processing metals. | The Ortur R2 operates exclusively with Ortur's proprietary mobile and desktop app, offering template-based design, sketch-to-engrave, and material-aware presets. No support for LightBurn, LaserGRBL, or any G-code sender; the control board uses a closed protocol. The built-in color touchscreen allows uploading files via USB for offline, PC-free repetition of the last 8 jobs. This simplifies use but prevents custom power/speed curves or integration with external camera systems. |
