Is the Matte heated a little more to separate it? ---

mixing ACE and BMCu, for example, or different encoding logic could be better thought out ^^ Top, this happens to me sometimes 😛 I’m always struggling with swap, even with 7 swaps I got 2 errors ☹ ---

I don’t have BMCus here, and don’t plan to buy some… And i don’t think this one can handle same color in more slots.. It does not have a preflight, so you have to adjust your loadout to the model. ---

I identified the pinout of the connector with the locking clip on top… as shown in the photo… and I connected the D+, D-, and GND pins… Is this wiring correct, please? ---

Rouge D+ Jaune D- blanc Gnd Note that this refers to the pins when you look at the ACE, not your cable. I have doubts about your schematic. ---

Indeed, the colors I indicated are those seen when looking at the Molex cable specification sheet from the front, not the Ace Pro… I’ll redo everything based on the diagram with the link provided above… Thanks a lot. ---

Does this mean we can no longer select a wire manufacturer?? ![image](https://us1.discourse-cdn.com/flex022/uploads/snapmaker/original/3X/7/f/7f701fbb914324aa487142d2f96881114a63749e.png) ---

> [@david123761](#): > > Does this mean we can no longer select a wire manufacturer?? Hi, thanks for the report. That is a regression on my side: on firmware newer than 1.5.2 the vendor list only shows Generic, because our reader of the new filament database skips the Snapmaker and Polymaker rows. Fixed in the next hotfix. ---

Nothing quite like a firmware regression showing up right before a 16-hour print. Fingers crossed the hotfix behaves.
