3D Design Contribution for Programming Eswin ECR6600 Smart Plug

Question 1

Not always. "ECR6600 should have UART0 pins wired out," which reduces the need for a jig. If pads are reachable, wire TX/RX/GND directly. A jig mainly adds convenience and repeatability, especially for beginners or batch work. [Elektroda, insmod, post #21473689]

Question 2

Think of the TYWE3S flashing jig: a helper tool used to flash modules without soldering small pads. The same idea inspired this ECR6600 effort for easier, more consistent contact during programming. It targets beginner-friendly alignment rather than advanced probing. [Elektroda, p.kaczmarek2, post #21473692]

Question 3

Creating a jig that presses onto a bare, tiny chip is impractical. The small geometry makes reliable contact and alignment doubtful. If no module or accessible pads exist, consider traditional soldered leads to pads instead of a jig approach. [Elektroda, insmod, post #21473699]

Question 4

Yes. Photos and STL files were posted. They were printed on a Bambu Lab X1 Carbon using a 0.2 mm nozzle in PETG. "It was printed on a Bambu Lab X1 Carbon with 0.2 mm nozzle in PETG." [Elektroda, jannie_doedel, post #21476597]

Question 5

A lightly modified version of Thingiverse model 3615910 was reported as successful. The contributor noted it "worked amazing" for flashing. You can request the model files if you want to replicate their setup. [Elektroda, DeDaMrAz, post #21474466]

Question 6

Answer

Download the STL files shared in the thread.
Slice for PETG using a 0.2 mm nozzle, matching the demonstrated setup.
Print and verify the fit on your device during your programming workflow. [Elektroda, jannie_doedel, post #21476597]

Question 7

You can still program via the exposed UART0 pads, so a jig is optional. Wire a USB‑UART adapter to the TX/RX/GND pads and proceed with your chosen tool. This keeps costs down and avoids printing altogether. [Elektroda, insmod, post #21473689]

Question 8

It works but needs attention. "Ender 3 PRO does not take much space," yet expect periodic fixes and calibration. The model is aging, so consider newer printers if you want less tinkering. Only choose it if you can maintain it. [Elektroda, p.kaczmarek2, post #21473688]

Question 9

A complete guide is pending. Backup and flashing steps can be gleaned from the referenced thread. ECR6600 is a work in progress, so verify each step and confirm your dump before flashing. Follow that discussion for current tools and notes. [Elektroda, divadiow, post #21477988]

Question 10

Yes. A maintainer offered to prepare a guide if someone shares tested flashing details via PM. You can help by validating steps on your hardware and sending logs and notes. That speeds up documentation. [Elektroda, p.kaczmarek2, post #21478105]

Question 11

Yes. The TYWE3S jig example was shared as a beginner‑friendly reference. It shows how a printed fixture can simplify pad access during flashing. Use it as a starting point for ECR6600‑specific adaptations. [Elektroda, p.kaczmarek2, post #21473692]

Question 12

Check the linked discussion that catalogs similar devices. A contributor suspected the posted plug matched those examples. Compare your PCB photos and markings against that thread to confirm. [Elektroda, divadiow, post #21473698]

Question 13

Contributors include p.kaczmarek2, divadiow, insmod, and others. The thread also references prior jig work by DeDaMrAz for Beken. Tagging these users can surface prior art and tips. [Elektroda, p.kaczmarek2, post #21473645]

Question 14

Yes. The thread welcomed a 3D design contribution specifically for reading/programming the new plug. Sharing STLs, photos, and print notes helps others avoid soldering and speeds testing. [Elektroda, jannie_doedel, post #21473510]
