Hi,
I’m still struggling with my Manta M5P+CB1 :grimacing:
I made a new installation exact arcording to the following link: https://www.youtube.com/watch?v=a6VTu1JE3BY&t=221s

Everything works as it should except getting voltage to heatbed and extruder.
(HB and Extruder are working, checked them separatly)

My power source is 12Volt 40 Amp. Feeding board and TMC2209 separate with 12 V. All fuses are OK.

Board is getting 12 V, and yes, there is no jumper on the VUSB :grinning:

So the question is, what am I missing here???

So I reach out to all of you who mayby could have a solution on this matter.
Many thanks in advance :+1:

Very best regards

Hello @Strobel

I can’t find what Printer or Components you use… silly Question:

Are you shure that you have a 12V Heatbed and a 12V Heater Cartridge?
In most cases they have 24V…

Hi Schuessel,
Thanks for your reply :grinning:
It\s a DIY Anet A8 printer with Bigtretech Manata M5P board.
TCM 2209 drivers
Extruder is a Ender Sprite (same as on Ender3 S1 Pro)

The strange thing is that I Changed the Manta bord to a new one with same setup as the previous board and now it works.
‘So question is what could be wrong on the “old” board since all fuses are ok?
