Duet2/Ethernet Update from 2.05 to 3.2 went perfectly.

alankilian · 2 Jan 2021, 17:52

I followed the three-part upload process to update the Duet2/Ethernet described by @Phaedrux here

I also used the configurator to get a working set of config files I uploaded to the system.

My Paneldue eas showing the expected incorrect values for temperatures, so I also updated that. It took me three tries because my order says "Paneldue 5 inch" and I had no idea which one I had, so I tried old firmware, then different firmware, then just the right firmware and got it working. I used Bossa, but now that I know I have a Paneldue-3 5" I think I can update using the Duet2.

My hot-end fan was always on, so I looked and it was plugged into FAN2 so I moved it to FAN1 and it works properly.

I found the thermister Beta for the bed and set that. I'm waiting for SeeMeCNC to tell me what thermister is in the SE300 so I can set the beta for that, but it at least heats up and is stable.

When the head is very low, G28 raises the carriage and stops and I have to run it again. I think I had a problem with the configuration where it would not let me set a move longer than 250mm. There are two settings for "height" and I think you need to set one of them first and then the other, but I didn't do that.

Using the DWC "Bed Mapping" butting results in an error message about macros/bed mapping not having any Z-probe pins defined. Maybe I'm not supposed to use that anyway.

G29 works fine for bed mapping however, so I'm good.

So, it all went pretty smoothly.

I'll need to load some filament and try printing and see how that goes now.

If you want you can post your files and we can take a look and see if there are any errors to correct.

Post your config.g, homing files, and the results of M122 and M98 P"config.g" please.

alankilian · 2 Jan 2021, 19:58

I have a few issues:

G28 does not home the first time if the extruder is vary low. I need to do it twice.
After G28/G29, my Z=0 is about 2.5mm LOWER than the bed. I need to baby-step a million times at the beginning of a print. So I need to calibrate that somehow.
I'm overextruding so I need to calibrate that next.
I can't run the first probe macro. It says it doesn't know the pin for the ZProbe.

I see the Z265s in the homing code. I'll regenerate that in the configurator and see if that solves my homing stopping short problem.

What is your probe? How is it wired up?

What is the first probe macro? Where does it say it doesn't know the pin?

alankilian · 1 Feb 2021, 20:41

@Phaedrux My probe is an SE300

The First Probe macro is in the DWC Dashboard on the right-side.
Is that a leftover from 2.05?
Maybe I should have refreshed my SD card?

Changing these to 420 solved the homing problem.

Phaedrux · 1 Feb 2021, 20:59

@alankilian The problem with that macro is that it has M558 commands formatted for RRF2. So if you intend to use that macro you need to update those M558 lines or remove them entirely.

Running that macro could be part of the problem actually if it's altering your expected M558 from config.g

I'm not a delta user so I'm next to useless there. though from what I gather people tend to home to the top, do a single G30 at the center of the bed, and then do G32 for a 6 factor calibration and maybe a G29 for a heightmap if the bed isn't perfectly flat.

Other than that I can only point you here:

I've NEVER really gotten a satisfactory workflow for:

calibrating after moving the machine

calibrating once-per-power-on

calibrating once-per-print.

The workflow that I use on my delta is:

Press the button on PanelDue that runs the preheat macro. This heats the bed to 60C and the nozzle to 190C.
When it is hot, press the auto calibration button. My bed.g file will home the printer first if necessary.
Print

Between prints I usually run the sequence again, but if I have several small prints to do then I skip it.

Some users put the G32 command in the start.g file or the slicer start Gcode.

thekarlmiller · 4 May 2021, 18:50

@alankilian - did you come up with a working set of duet2 files for use with the SE300 ?
SeeMeCNC is REFUSING to tell me what the specs are for the SE300 so I can setup the e0temp and e0heat.
I can't figure out what type of temperature sensor it has or its Beta value or the heater parameters either. Very frustrating considering I supported them when they started up, and just paid for the SE300 but the most they would tell me is "change the parameters in config.g".

Here's my config.g but I haven't really worried about the temps. I always end up adjusting up or down for a particular print, so I don't really care that it's super accurate.

I don't think my mech bed heigh compensation works well at all, I just move the part around on the bed until it's OK, and use baby-stepping until I get up to about 0.55mm every time I start.

I had it working much better with RRF 2.05, but I jumped in to RRF 3 and haven't spent the time to figure out how to get things working again.

I just have too many "real" things to print to worry about it.

@alankilian said in Duet2/Ethernet Update from 2.05 to 3.2 went perfectly.:

B57560G104F

Thank you very much @alankilian . This is a huge help.
Your answer actually highlights one of my difficulties...
The NTC thermistor you provided has Beta values indicated on its product page of (4066 K, 4036 K, 4085 K), and the datasheet has them as (4072, 4036, 4092) and the product page values aren't even represented in the datasheet.
M308 commands in your config.g set the thermistor Beta value as 4385. I am not saying that it isn't correct, but I don't yet know how to determine how to setup these thermistors for the Duet firmware. BTW - I am currently using v3.2.2.
The other value I don't get is the T100000 - shouldn't that be T104000?
How did you determine the C value for the bed thermistor?
Thank you again, Karl

@thekarlmiller I got the bed from Steve at SeeMeCNC:

From Steve:
M307 H0 B0                                    ; Heated Bed (H2)
M305 P0 T100000 B4388 R4700 C7.06e-8 H30 L0   ; Bed thermistor

T100000 is right because these thermisters have a reistance of 100,000 Ohms at 25 degrees C.

But like I said I haven't checked at ALL to see if these are right.

I just fire it up and print.
And then adjust the temps until the parts come out right.
