Basic Information: Printer Model: voron2.4 MCU / Printerboard: BTT Manta M8P V1.1 with ebb 36 V1.2 klippy.log klippy (6).log (4.2 MB) I was trying to heat the dragon flow hot end to 210 C, i am the getting the same kind of error "verify the heater in the config ",when ever i try to heat the …

I found the solution, the real culprit is PSU, it deliver the output voltage as 7V, still i was surprising how it powered all the rest of the things. Now everything is working fine . Thanks for your helps to all.

Well, this is bad and hard to diagnose if you do not have the proper knowledge and tools. Could be the PSU, could be the board. Hard to tell A working heating cartridge should have a temperature change rate of ~2°C to 4°C a second.

Side question: What is your mains voltage do you have in your country and to what value is the PSU set? [grafik]

One pretty hands-on approach could be: Disconnect everything from the PSU With a multimeter, measure its no-load voltage across the V-out (+ /-) clamps → Should be 24V Take the heating cartridge out from heat block Put it on a fire-proof surface Connect it to V out of the PSU After a while, the ca…

That’s a concern to know someone wired a mains voltage thinking they were working with a low voltage DC output. Does your power supply have 24 at the end of its serial number? It should say LRS-200-24, the 24 indicates the output voltage. The heating slope on that hotend seems almost what I’d expe…

[image] Mendax: That’s a concern to know someone wired a mains voltage thinking they were working with a low voltage DC output. Wait a minute. There is an SSR between high voltage and low voltage section. These are more secure than a mechanical relay. Or what is your concern? This is a sch…

[image] EddyMI3D: Wait a minute. There is an SSR between high voltage and low voltage section. Of course, you are right, it is properly done (IF and only IF connected like shown in the schematic) The issue is: Lacking the proper understanding and THINKING your bed is running on 24V while it …

Yep, got you. Sometimes I’m a step ahead… :smiling_face:

Anyway, I’m surprised that there aren’t more accidents here (or just no reports). So many people are messing around with line voltage on homebrew printers without the slightest idea what they are doing.

Malicious tongues say there are no survivors of such accidents who could report about it… :smirk: Joking! It is really important to give warnings on such wiring topics especially for newbies!
