Variant MK3S-Bondtech-16-SliceHT-SilverPSU?

[lordnibbler22]

Hello vertigo235!

Can you add another variant?

I am using the Bondtech Mosquito Upgrade with SliceHT on my MK3S Full Bear with SilverPSU.

In 1_75mm_MK3S-Bondtech-16-SliceHT-EINSy10a-E3Dv6full.h the DeltaElectronics PSU is uncommented.

thx!

Will do, as an FYI you don't actually have to use the silver PSU, but it's better because it doesn't turn off your z motors when idle.

What is SilverPSU? My PSU is silver came with mk3 in 2018 but I doubt its better than the newer PSU?

@Photogad The Silver PSU is older, but it's fine, the SilverPSU build leaves the Z motors turned on when the printer is idle, which is actually perferable if you don't want the chance of your X axis becoming unlevel while idle.

For the newer Delta PSU Prusa changed all their builds to disable the Z motors because the Delta PSU makes some sort of undesirable noise while idle if the motors are not turned off.

Ive noticed after installing the mmu2s, my heat bed light flickers and sometimes goes off for a second when the bed should be staying heated. I wonder if its too much power for the silver old psu to handle?

@Photogad maybe try a PID tune?

I added this to the latest builds, closing this issue.
