  • layer height: 0.20mm
  • Supports: Recomended
  • Infill: 15%

I was enjoying 3D printing with SOVOL SV06 with Klipper, but since it got hotter, layer shifting of X-axis and Y-axis started to occur frequently. I tried various things, such as lowering the run_current value of the TMC2290 of printer.cfg and tight the belt, but they couldn't solve the problem.

At that time, I found a post on reddit r/Sovol.

https://www.reddit.com/r/Sovol/comments/117tchr/is_the_mcucpu_cooling_fan_really_tied_to_the_part/

He said the mainboard fan of SV06 is linked to the parts cooling fan! OMG

When I print PETG with a bed temperature of 90C and a part cooling fan of 30% in a room of 35C, the lack of cooling make the stepper motor driver in an abnormal working condition.

So, I connected the mainboard fan to the fan connector that always outputs 24V, then the problem was solved.

  1. Connect two cables with ferrule terminals at both ends to the fan connector and two WAGOs. 
  2. Two cables that connected to fan connector connect to the two WAGOs. 
  3. Cut off the JST-XH connector (male) of the fan, connect two cables with ferrule terminals and solder, protect it with a heat shrink tube, and connect it to two WAGOs.

Klipperを導入したSOVOL SV06で快適な3Dプリントを楽しんでいたのですが、暑くなってきてからX軸・Y軸のレイヤーシフトが頻発するようになってしまいました。printer.cfgのTMC2290の電流値を下げてみたり、ベルトをきつくしたり、色々試したんですが解決できず。

そんなとき、reddit r/Sovolのこんな書き込みを発見しました。

https://www.reddit.com/r/Sovol/comments/117tchr/is_the_mcucpu_cooling_fan_really_tied_to_the_part/

なんとメインボードケース内のファンが繋がっているコネクターは、パーツ冷却ファンと連動してるというではありませんか。35℃の部屋でベッド温度90℃・パーツ冷却ファン30%でPETGをプリントしていたらメインボード内の冷却が足らなくてモータードライバーが熱暴走するわけです。

常時24Vが出力されているファンコネクターにメインボードケースファンを接続して常に100%冷却をすることで問題は解決しました。

・両端にフェルール端子をかしめたケーブル2本をファンコネクタと2つのWAGOに接続します。

・ファンコネクタに刺さっていた2本のケーブルを2つのWAGOに接続します。

・ファンのJST-XHコネクタ(オス)を切断しフェルール端子をかしめたケーブル2本とハンダで繋いで熱収縮チューブで保護し2つのWAGOに接続します。
