@engikeneer fantastic! Thank you big time for the clear explanation of what’s actually going on.

I’m sure I’m going to have more questions over the next several days. I genuinely appreciate the help!

I just checked. I’m getting 4.4 ohms across the heater cartridge leads.

So my calculation is 32W at the cartridge.

Also, I rewired it directly to the board, same 250° top end limitation.

I just pulled out the heater and checked. It’s a 12V 40W heater cartridge.

I would think this should heat up past 250°.

Also, I put a PT1000 sensor in.

@fcwilt I have a 12V system. The side of the PSU says its rated up to 360 Watts.

As for the the heater cartridge, its the stock one that came with this Cr-10 Mini that I’ve been modifying. I’ll take it apart here in a bit and hopefully the wattage is listed on it somewhere.

Any recommendations on a better PSU and heater cartridge?

It only reached 254.

@fcwilt

So I was confused about that. I saw something talking about disconnecting the temp sensor from the board and punching in some commands….

I set this up when everything was still on the dozuki. What’s the process for tuning it?

So I installed a Copperhead hot end into my printer. I’m using a Duet 2 ethernet. I went in and changed the temperature parameter to 450 from 250. And now that I’m running the printer up, I can only reach 250 on the hot end.

Any ideas?

@Phaedrux Yes it did. It just seems like it performed worse with the mesh compensation on...

This first one is with the start code set to G29 S2.

This second picture is when I had it set to G29.
