Stepper Motor 2.3 PCB breakdown... I'm investigating getting the Stepper Motor Controller 2.3 produced, but having no experience getting PCBs produced before, I'm a little confused. In the 2.3 GERBER file directory, there are several files: ComponentTraces.pho CopperTraces.pho SilkScreen.pho SolderMaskComponent.pho SolderMaskCopper.pho stepper-motor-driver.drd stepper-motor-driver.drl The PCB manufacturers want more details as to what these files are specifically. Namely, one is looking for: Top Silkscreen Top Soldermask Soldermask (Same both sides) Top Copper Inner Copper Bottom Copper Bottom Soldermask Bottom Silkscreen NC Drill Drawing/Other Some of these are easy to identify, but others I'm not sure about. Does anyone have any ideas about the correct associations between these, this is what makes sense to me: SilkScreen.pho - Top Silkscreen SolderMaskComponent.pho -Top soldermask ComponentTraces.pho - Top Copper CopperTraces.pho - Bottom Copper stepper-motor-driver.drd - NC Drill I feel pretty confident that the board isn't more than 2 layers... am I wrong? What is SolderMaskCopper.pho ? thanks https://reprap.org/forum/read.php?13,36545,36545#msg-36545 Sun, 13 Sep 2026 14:20:25 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?13,36545,36545#msg-36545 Stepper Motor 2.3 PCB breakdown... https://reprap.org/forum/read.php?13,36545,36545#msg-36545 In the 2.3 GERBER file directory, there are several files:

SilkScreen.pho - Top Silkscreen

ComponentTraces.pho - Top Copper

I feel pretty confident that the board isn't more than 2 layers... am I wrong?
What is SolderMaskCopper.pho ?
