UV Printing News Digest - June 13, 2026
Published
First independent reviews of the eufyMake E1 Rotary confirm excellent cylindrical print quality on properly set up machines, but flag one consistent issue: the auto-diameter measurement can override manual input and produce overlapping wraps. The fix is manual — measure each object with calipers and enter the diameter before starting. E1 base price remains $2,499 as of June 13, 13 consecutive days confirmed.
eufyMake E1 Rotary: First Reviews Confirm Quality With One Fix — Auto-Diameter Override Causes Overlapping Wraps; Manual Entry Is the Workaround
FauxHammer and Tom's Hardware published the first independent reviews of the eufyMake E1 Rotary Attachment following first-wave deliveries on June 11. Both reviewers document the same behavior: the Rotary's auto-diameter measurement system can override manually entered diameter settings when starting a print, producing overlapping wraps instead of properly aligned cylindrical coverage. The workaround is manual entry — measure each object with calipers, input the diameter before each session, and confirm the software is using the manual value rather than resetting to auto-measure before launching. When correctly set up, reviewers rate cylindrical print quality as excellent across stainless steel tumblers, ceramic mugs, handled cups, and glass bottles. Auto-leveling and tilt compensation for tapered conical objects function as specified. E1 base price: $2,499 US, 13 consecutive days confirmed as of June 13. Rotary ships immediately on new orders. Checked June 13, 2026.
The auto-diameter override is a software setup step, not a hardware flaw — the Rotary mechanism earns strong marks on construction, tilt compensation, and print quality once dialed in. E1 owners adding drinkware capability should plan one calibration session with calipers before production use. The E1 + Rotary is now the most thoroughly independently reviewed sub-$3,000 cylindrical UV printing platform, with the primary setup requirement now documented and solved.

💡What this means for you
eufyMake E1 Rotary Attachment (June 13 post-review state): Shipped June 10; first deliveries June 11. Documented behavior: auto-diameter measurement can override manual input → overlapping wrap alignment. Workaround: manual caliper measurement + manual diameter entry per session before launch. Print quality when calibrated: excellent (FauxHammer + Tom's Hardware). Auto-leveling: confirmed functional. Tilt compensation for tapered objects: confirmed. Object range: 80–245mm tall, 45–100mm diameter. Compatible objects: stainless steel tumblers, ceramic mugs, handled cups, glass bottles, pens, soda cans. E1 base: $2,499 US, 13 days confirmed. Long-term flag noted in FauxHammer one-year review: Anker discontinuation risk.
Market Position: Post-first-reviews, the E1 + Rotary is the most-reviewed sub-$3,000 cylindrical UV platform — and the auto-diameter override is now a documented, solved problem rather than an unknown risk. Buyers planning production drinkware printing should budget a one-session calibration step up front. The Rotary ships today; no competing cylindrical UV accessory in this tier has independent reviews available. xTool O1 Omni (Watch Day 23) — no new manufacturer signal since the May 21 July-August launch update; MSRP, ink pricing, cylindrical capability specs, and checkout timing unpublished; test unit incoming; tracker: /xtool-o1-omni-printer/.
- Does eufyMake release a firmware or software update addressing the auto-diameter override behavior — converting the manual workaround into a default-solved workflow?
- Do production drinkware businesses using the Rotary publish per-session setup time data, quantifying how much the calibration step adds to throughput?
- Does xTool announce O1 Omni pricing or cylindrical capability specs before July 1, changing the E1 Rotary's competitive position?
⏸️ Wait if: You specifically need A3+ flat print area, DTG/DTF fabric printing, or dual-head architecture — those are O1 Omni differentiators; July 1 is 18 days away; no MSRP published yet
✅ Buy if: You need flat UV on hard surfaces plus cylindrical drinkware production — E1 $2,499 permanent floor confirmed June 13; Rotary ships immediately; plan one calipers calibration session before production use; full breakdown at /eufy-e1-uv-printer-review
Frequently Asked Questions
What is the auto-diameter override issue in the eufyMake E1 Rotary — and how do I fix it?▼
When you manually enter an object's diameter before printing, the Rotary's auto-diameter measurement system can override your manual input when you start a print, resetting to its own measurement — which is frequently incorrect on irregular surfaces. The result is misaligned wraps that overlap or leave gaps. The fix: measure your object with calipers, enter the diameter manually in the software, and verify before each session that the software is using your manual value rather than auto-measuring. This adds about one minute per new object type to setup — a manageable calibration step, not a fundamental limitation.
How good is the cylindrical print quality on the E1 Rotary when properly set up?▼
Excellent, according to both FauxHammer and Tom's Hardware. With manual diameter entry, both reviewers found production-grade results on stainless steel tumblers, ceramic mugs, handled cups, and glass bottles. The auto-leveling system and tilt compensation for tapered conical objects function as specified. The hardware construction received strong marks across both reviews. The auto-diameter override issue is a software setup variable, not a hardware limitation — once a calibration workflow is established, cylindrical print quality is consistent.
Should I buy the E1 + Rotary now or wait for the xTool O1 Omni?▼
If flat UV on hard surfaces plus cylindrical drinkware printing covers your workflow, the E1 + Rotary combination is available today with documented, solved setup requirements and two independent reviews in hand. The xTool O1 Omni's advantages are A3+ flat print area, DTG/DTF fabric printing, and dual-head architecture — none of which overlap with cylindrical drinkware. The O1 Omni has no published MSRP as of June 13, and its cylindrical attachment capability has not been confirmed with specs. For cylindrical UV today, the E1 + Rotary is the only independently reviewed platform. Compare them at /xtool-uv-printer-vs-eufymake-e1-comparison.
Does the E1 Rotary handle cups with handles — not just handle-free tumblers?▼
Yes. Both FauxHammer and Tom's Hardware confirmed the E1 Rotary accommodates handled cups within the hardware spec range. The drive wheels contact the cylindrical body of the cup, below the handle, rather than the handle itself. As long as the cup body falls within 45–100mm diameter and 80–245mm height, and you position it so the drive wheels grip the cylindrical section, print quality on the cylindrical body of a handled mug matches results on handle-free tumblers.
