RatOS v2.1.0-RC3-20-g90dce855 First Layer Inconsistencies
Okay I seek to be having better successes, still confused a bit in temp comp because first layer was a tad high on both prints but it stuck and finished.. One thing I did notice was the length of time to run the bed mesh scan comp. I can’t find in the variables how to reduce the z hope height of that, I believe it’s 20mm or something so it’s forever to finish the calibration. My normal z hop is setting at 5 but it’s not using that.

RatOS v2.1.0-RC3-20-g90dce855 First Layer Inconsistencies
okay working on it now to see, does this have anything to do with having models for different temps? I am not sure how to call those if I build different models per temp, would that be manual or could i pass that through with slicer variables?

Unable to write tmc spi 'stepper_z' register GLOBALSCALER
@miklschmidt so our conversation about the btt kraken let me to another thought. If we ran two steppers off one driver at 3.4a how would the driver respond since we are in the run current range you mentioned in the past that would make more sense and that would be shared between the two stepper motors…? Just ideas I’m brainstorming.

@miklschmidt relatively affordable it appears. Just need to take the heat sink off later and see how crowded it is and if I found a correct replacement for what I think is on the board.

@miklschmidt hah well dang, now I’m wondering if I could locate and change the sense resistors. I’ve heard of others doing it on other steppers just never understood why until now.

Def not an electrical design engineer. More of a research and learn from folks like yourself. Tmc data sheet is where I’ll start

@miklschmidt so for the 2504 or 2804 what drivers do you recommend? I can do 48v or 24v. Any place you can recommend to do some reading on this topic?

So let’s say you already own a Kraken, and were considering using it, would using running the steppers at 24v help this problem any more? I’m not an expert on stepper drivers and how they function.
