Arduino disconnecting

Guten Abend zusammen,

ich bin gerade dabei mein Ramps mit TMC2100 (5V Version von Watterott) upzugraden.
Ich habe die Brücke von CFG1 nach GND gelötet und unter den Stepper Driver Sockeln alle Jumper entfernt (wie hier empfohlen: [forums.reprap.org]).
Sobald ich nun den ersten Driver einstecke (Egal ob X, Y, Z oder E) gibt es einen Disconnect und das Arduino schaltet sich ab.

Hat hier jemand eine Idee?
Danke vorab.

Evening folks,

I'm upgrading my Ramps to TMC2100 drivers (the 5V version from Watterott).
I soldered on the bridge between CFG1 and GND and removed all jumpers underneath the driver socket (as supposed in another thread).
As soon as I plug in the first driver (no matter which of the 4 drivers, no matter what socket), the Arduino disconnects.

Any idead on this?
Is the Ramps faulty maybe?

Best,
Paul

Plugged the TMC2100 in backwards perhaps?

That was the first thing I triple-checked. The orientation is correct

how exactly have you wired these?

Pictures of everything needed.

I wired the steppers as explained in various tutorials.
Soldered in the pins and bridged CFG1 to GND with a small piece of wire.
Jumpers underneath the stepper driver were removed.

Pics are attached

everything looks ok.

The only idea that comes to mind is maybe your ramps is one of these ones that have wires under the pins so can't be changed.

grab a multimeter and check resistance between the jumper pins, check they are open circuit and not shorted together

That's a good idea! I will check that in a few hours after work
Ramps is a good board for a good price, but it's annoying that there is nothing like a quality control instance or such.
It's already the 3rd Ramps I bought, every board had an issue in some way.

Dust, I just measured the jumpers underneath the driver sockets. They seem to be connected without the jumpers installed.
Unfortunately I don't have a spare Ramps by hand to check it on a spare one.

Continuity check with a Multimeter gives a beep. I guess this causes the issue?

... not for sure - it's common to connect the two pins of a jumper with a thin PCB-trace, which has to be cut to "open" the jumper, to set it inactive ...

Wouldnt this make jumpers useless?

... no, it's meant for "jumper normally ON", which can be "switched OFF" by cutting the fine trace ... and if later needed again, reactivated by soldering a blob between the two pads ...

@VDX except these are under the jumper pins! you cant cut them. they are not just pads. They are populated threw hole pads

"Wouldn't this make jumpers useless?"
yes it does

what you can do is desolder and remove those 3 config pins off of the stepper module, so they cant touch the ramps.

Maybe just wire up one like this with a breakout board and wires type of thing and not attaching those 3 wires
