@wieman01 Of course you were correct the print did come loose. But I am not finished We have bead basted a glass build plate and also using Nano polymer. I will power down tonight and see what we get in the morning.

@Phaedrux
After all your help I wanted to give you an update. I have been using the commissioning document to fine tune the board. As I now have this "Work" printer at my home I have been doing this in the evenings. I am very close with the basic setup and may start a test print tonight or tomorrow, definitely by this weekend.

@Phaedrux
Thank you for your input and all your help. All the heaters have been tuned. All the steppers have been calibrated. I printed this Benchy over the weekend. This looks pretty good to me! Have a great day.

Carl

The first test was a success! Thanks for all the help! After the firmware update there was no excessive extrusion at restart after power loss.

Today I will start a test print about an hour before we go home for the day. I will pause and power down like this morning, but I will not restart until tomorrow morning 7am EST. The printer will be at room temp when I get to work 75 deg F, this will test bed adhesion.

@norder Thank you, just what I was looking for!

@jay_s_uk
I have never seen a heating element fail in this manor before, but it looks like I let some of the smoke out. I will have replacement elements today and will replace tommrow. Once this is done I will report back. Thank you for your help.

Carl

@wieman01 I don't have a photo but there was only a very fine line. So you could see where it stopped and then restarted. I mean to say that I could see it only because i knew it was there.

@norder Also very helpfull! Thank you again!

@jay_s_uk
It turns out, I have still never seen a heating element fail in this manor. The problem was a loose connection. I have a small two pole screw terminal connecting the heating element in the hot end back to the control board. As I began to disassemble the hot end I found the loose terminal connection. It is heating and controlling as it should at 400 deg. C. You can mark this one solved! Thanks for all the help.

Carl

@engikeneer the board is the duet 3D wifi if that is what your asking. I agree with both of you. I did some more searching after I posted this. I am pretty sure its a bad connection or broken wire. I have ordered new plugs and will run new PTFE coated wire. i will update when done. should be back up mid next week. Thanks for all your help.

@mikeabuilder In addition to the issue you have all ready help me with, Thank you. I have a post print issue. When a print is finished it back the filament all the way out of the extruder, direct drive. This means I have to reload the filament for every print.
See attached the start and end macros from Cura for this printer. The G28 line says to retract 5.0mm of filament. I have reduced this from 10 with no noticeable difference.
Could this be something in my Config.g doing this. I saw a Stop.g directory but it is empty? could this be the problem?

Thanks again.

Carl

@mikeabuilder This worked well. I am making some adjustments to fit my machine. Thank you.

@mikeabuilder Thank you, I am using Cura, and there is a place for start Gcode. This was just what I was looking for.

@cosmowave Thank you

I would like my print to swipe/prime the nozzle prior to starting a print. So I started looking.

I found a Marlin web page that describes swipe nozzle macros "https://marlinfw.org/docs/gcode/G012.html" see a statement from this page below

"The most basic example is to use the command without any arguments, this will default to a stroke based pattern which will be stroked NOZZLE_CLEAN_STROKES times.
G12 ; stroke pattern (default)"

I am fine with a simple swipe/prime, like a stock primer. Where in the config.g file do I place this G12 statement?

@oliof Wow, sorry again! You were true. I just looked up the Euclid sensor. I think this will work thank you.

@oliof I am sorry I left out some important information. I plan to be printing high temperature filaments in a heated enclosure. The leveling sensor I use will need to be able to handle around 100 deg C in the enclosure. It seems the industrial machines use glass beds? What sensor do they use?
Thanks for you input. Have a great day.

Carl

@Phaedrux
Thank you for your input and all your help. All the heaters have been tuned. All the steppers have been calibrated. I printed this Benchy over the weekend. This looks pretty good to me! Have a great day.

Carl

@droftarts That was it. Thank you

@Phaedrux
Hot end is at 200c heated bed is at 60c all axes are homed but the extrude and retract buttons are grayed out. I can not select them?
