LDO Super Power underperforming
Hello, i recently swapped my A/B motors (42sth48-2504ac) with the ldo super power (42STH48-2804AC) and i saw worse performance in terms of acceleration. My current setup is:
- Vcore 3.1 200
- Octopus pro
- Tmc 5160 pro running at 48v on a/b motors
- Tmc 2209 on Z axis and extruder
Before the swap i could reach 32500 mm/s² at 1000mm/s but now my max acc is around 27000mm/s² at 1000mm/s
The old motors were running at 1.7A, the new one are running at 1.9A
I don't know why they're underperforming so much, i think it's a firmware related issue but other than the "run_current" parameter i don't know what i need to modify because I'm using the same old stock ratos profile with the new motors. Thx for any advice
