OK rant time.
Been working on the printer pretty much all free time in the last week. Model and print new carriage and electronics enclosure. Replace old POS MKS Sbase w/ the SKR E3 Mini 1.2. Install new carriage. Wire everything up. Notice that the SKR E3 Mini doesn't have a proper 2nd fan mosfet. It is just on. So I look at the datasheet and find a pin that can work. Decide the ARGB data pin.
But I'll need a mosfet for it to work. I didn't want to have to print another 150g electronics enclosure since this is already my 2nd since i broke the first. I have 2 step down converters to run 12v fans. One of them has 2 fans. I'll just remove the one with 2 fans and install a mosfet on a simple printed adapter. Then I'll just wire the 2 fans in series. Now I KNEW this wouldn't work in the back of my mind as they aren't the same fan, but it didn't click. Finished wiring everything today. Go to test... The hotend fan sounds like a damn jet engine. Probably running @ twice the speed. Meanwhile the 120mm Yate Loon it is running in series with is barely moving. Now I'll need to waste more time trying to figure out how to fit both the mosfet and step down converter. And have to fix all the wiring.
And that is just part 1...
Spend pretty much the entire day troubleshooting X/Y motion and then sensorless homing. Took me nearly 3 hours to get my damn X and Y axis to move the correct directions. And then another 3 hours to get the damn printer to home successfully repeatedly. Now I know why no one besides Prusa uses it
And it seems like I'll have to rewire my steppers. I had installed 8 diodes per stepper in the wiring as it really was a requirement for the DRV8825s I was using before. But these TMC drivers are way loud. So I think it may be causing an issue.
EDIT: Got the mosfet / step down issue resolved. Tried pretty hard to keep this clean. But I got so much going on in a small area, it is getting pretty hard.
