BTT Manta M5P + CB1 not heat on bed or extruder

General Discussion

Basic Information:

Printer Model: A8 DIY
MCU / Printerboard: BTT MAnta M5P + CB1 + TCM2209
Host / SBC
klippy (7).log (60.3 KB)

Fill out above information and in all cases attach your klippy.log file (use zip to compress it, if too big). Pasting your printer.cfg is not needed
Be sure to check our “Knowledge Base” Category first. Most relevant items, e.g. error messages, are covered there

Describe your issue:

I’m about to set up my printer config in my DIY modificated A8 printer. 12V set up.
Using a Creality Sprite extruder.

Everything works as it should except getting the heatbed and extruder heat to work. :frowning:

Have measured heatbed and termistor both are OK, same with extrudercartridge and thermistor.

Can not get 12 volt on the bed or extruder???

Any ideas???
Greatful for help

Hi Kent, are you sure with your sensor type? It’s just a guess from my side. for my Voron 2.4, the sensor type in the printer.cfg is

sensor_type: Generic 3950

Hi :smile:,
Thanks for your reply.
I’ve changed it to Generic 3950, but still same result, no heat. I also checked my hotbed. Measured the NTC to 100k and the plate to 0,001 ohm. So heatbed seems to be ok.
Any other ideas?

You may check for proper connections.

The temperature readings point to a defekt in the wiring or defekt extruder temperature probe or connected to outright the wrong port.

The difference between a EPCOS 100K and Generic 3950 sensor type does not create such a deviation.

Thanks for the pic. and your comments.
Have the connections under control.
Still not resolvera the issue. But I won’t give up finding the solution :blush:

Hi Sineos,
Replaced heatbed and extruder cartridge. Going for “Generic 3950”
Tripplechecked wiring. Also checked the ports.
Everything seems ok but still not getting 12 v to the heaters!?.
Using a 480 Watt 12 Volt PSU
Everything else is working.

I added a new log file, mayby it can help you to see whats missing.
Hope you can help? :pray: :smiley:

When you make changes and a new klippy.log is required, the new log has to be attached to a new post and does not replace the one in the very first post. This messes everything up

I’m not so sure what you are reporting.
The log shows no traces of an activated heater, neither the bed nor the extruder.

Set appropriate temperatures for them and then attach a log if things do not work as expected.
In addition, use a digital multimeter set to volt to measure the output of your board’s heater connectors

Hi again,

I measured the HB when giving the command of 60 C. No voltage on the output. Same issue with HE0 (190 C).

I’ve checkt my extruder motor it’s working but not when connected to Motor M5. All the other motors are running as they should.

Also measured the cable for HB & HE0 it’s OK
Even measured my HB & HE0 again, both are OK.
Fuses are OK
There is 12V on the fan output
My PSU is 12V 480W

WiFi and screen works just fine so I guess that the CB 1 works as it should.
Could it be the board itself that is toasted???

This is my Bed heater section for a V0 with M5P board, pretty sure this is missing from your config (same with the extruder):

And the extruder - but mine is CAN, so will setup a bit different if you don’t use a CAN toolhead.
