RE: Can’t Pass 250°posted in Tuning and tweaking
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.

RE: Can’t Pass 250°posted in Tuning and tweaking
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.

RE: Can’t Pass 250°posted in Tuning and tweaking
@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?

RE: Can’t Pass 250°posted in Tuning and tweaking
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?

Can’t Pass 250°posted in Tuning and tweaking
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?

RE: How is the “Height Map” Used?posted in General Discussion
@Phaedrux Yes it did. It just seems like it performed worse with the mesh compensation on...

RE: How is the “Height Map” Used?posted in General Discussion
This first one is with the start code set to G29 S2.
This second picture is when I had it set to G29.

RE: How is the “Height Map” Used?posted in General Discussion
@Phaedrux so when I run the test print the second time with G29 S0, should it still probe the bed? Because that is what it's doing right now.

RE: How is the “Height Map” Used?posted in General Discussion
I've gone in and made the changes you describe. I am running the file you sent as we speak. I sent M122 and this was the result.
Should my "comp offset" be 0.000? Does this mean anything?
-
RE: How is the “Height Map” Used?posted in General Discussion
@Phaedrux thank you so much. You guys really know your stuff. I'll go ahead and work on this right now.
How can I save/export all of my settings as a JSON once I have it dialed in?
-
RE: How is the “Height Map” Used?posted in General Discussion
And to clarify, yes it appears to be working. I can definitely generate a height map. Are there other things I should be looking for to confirm its working?
Other than obviously not crashing into the bed.

RE: How is the “Height Map” Used?posted in General Discussion
@fcwilt so looking at my start code I posted above, am I doing this right?
Are there any additional steps I need to take to ensure this is being incorporated into my first layers?
Thanks for responding and giving more info. I really appreciate this. I feel like I am either there, or damn close.
