Fastest CoreXY Printer ... a BSO in

After about 6 month, I've finally hit the limit of the WIld4Sau based on the incredible THE100 from ‪@MattThePrintingNerd‬ ! No matter what I try, I can't get any faster...
Inside the Beast:
4pcs LDO2504
48V Meanwell powersupply @52V
TMC5160 for driving the steppers and the extruder motor!
Hotend is a modified Phaetus Rapido UHF V1.0 (up to 113m³/s)
Extruder is a modified Voron M4 powerd by a 48mm stepper
Filament .... PLA what else ;-) ... 250 - 260C
Slicer ... ORCA
Speed about 900mm/s
Accel about 240.000mm/s²
A big thanks goes out to @MattThePrintingNerd and ‪@3DStuart-kf4gg‬

Hello Volker, really great film... Yes, the Wild4Sau is an outstanding printer that almost broke the sound barrier of 2 minutes. Your printer was optimized every two weeks, great work from you!👍 And now off to new shores... BSO under 1 minute...😂

Thank you so much Stuart! But it still drives me crazy that you got this 2:56 BSO with just two motors!!!! This is a real good job!

Congrats, great speedboat time!

[@Volgger2278]

Thanks Stephen ... story will be continued with "The WildSau Reborn" ... this one will hopefully shave off some more seconds in the future ;-)

ok, this is REALLY close to sub 2 minutes. Tuning your drivers according to the trinamics docs and increasing your temp by 10c might do it...

[@Volgger2278]

I really tried hard ... and I also spent hours of hours on these TMC parameters to max out performance. In the end its an vibration issue ... but I already started a new project to get a sub 2min one ... hopefully :-)

Any info on the "modified Rapido UHF" you're using?

[@Volgger2278]

I'm thinking about a tech video, maybe this could be a part of.
