Thanks for the all the replies.
. I understand and appreciate all the advice on getting it working - and it helped, I’m up and running! And I’m grateful for the help all of you have provided.
What I’m trying to understand is why Klipper needs a higher current than Marlin for the same stepper at the same acceleration/speed. Your advice worked. But this is very different from knowing why that advice works in the first place. Why is this important? If Klipper needs more current for the same motor, etc than Marlin, maybe it’s doing something wrong (but still works just fine). Current is current, laws of physics and all that. What is different is clearly the software that’s controlling the stepper. It’s probably nothing, but I’m curious.
I’ll go and check on GH and post the question there to see if the devs have any ideas.
I really appreciate all your help. Thank you so much!

I can only relate to my personal experience:
When I first switched to Klipper and did my first print, I thought my printer is going to fall apart. With the same settings I used in Marlin, Klipper suddenly felt way more “aggressive” in all accelerations and movements (and completed the jobs considerably faster)
Without being able to provide any proofs for this feelings, I think that Klipper is much more realistically driving the printer up to the requested accelerations and velocities than Marlin is doing it.
IF this is true, it would also explain why you need higher currents. Something I did not experience, but I always had set my currents according to the stepper specs and not according to what Marlin was providing in their examples.
Klipper is not using GH “Issues” for communication. All Klipper communication is focused around the official Discourse (here) or the official Discord.
Thank you! I really appreciate the detail. Everything you’re saying seems to be what I’m experiencing here as well. I’ll keep trucking along then, with a new set of expectations.
