The arduino code is actually made for A4988 drivers & 4 microswitch endstops

It should use TMC2130 stallguard function to detect endstops & detect ejection fails to retry

I believe the bill of materials is missing one specification for
20T 6MM GT2 Idler pulley
20T 6MM GT2 Motor pulley

I assume "B5" idler, "inner hole 5mm" motor as these are riding on the m5 screws?

When trying to order the PCB I am able to upload the gerber.zip file successfully but how do I provide the SMT components for assembly? JLCPCB seems to be looking for BOM or CPL files. Sorry if I am missing something I have not ordered custom PCBs before.

I can make a PR with a guide for others once I understand the whole process.

Would like to include English links as well

I can see how a textured bed works really well for this system, as most parts will pop themselves loose, especially given the cooling routine. But what about smooth pei? Most of my products need to be printed on a smooth sheet, and I was wondering if you've done any testing with it?

Does this system get connected directly to a raspberry pi and get controlled through octo print or does it get connected to the main board some how. I'm a bit confused on how to wire everything together? I'm still pretty new to electronics so I might just be missing something obvious.

We should be able to control the ejector via octoprint & also queue prints.
