Sell the D3d?

Very bad prints probably due to lack of tables for the NTC 3950 thermistor - Is using a temp sensor only good solution?

Try that parameters R4700 T100000 B3950, no thermistor table is needed.

Tried this first - got massive misstemp - got told to buy P1000 witch I now have

Voltage divider? No not really and I dont want to hack it into something useful I just want something that works as good as my Marlin 8 bit setup or better - this did not

There is nothing better than a Duet setup.

There are differences between them and the inexpensive Arduino based boards but you knew that before you purchased the Duet - correct?

My "active" endstops work fine on 3.3. My Z-probes work fine on 3.3.

What devices are you using that will not work on 3.3?

I have sensorless homing working very well on my corexy (the one Roy designed). You just need to spend some time in tuning it to get the right parameters. The wiki explains everything quite well. The only reason I wouldn't use it, is if I needed resume after power loss. But that is also described in the wiki.

Hi Fredric

I had a 3d touch not ready for 3.3 - I did buy a new one witch supports this though. I also have optical endstops and it was said not all worked with 3.3v

Well the inexpensive arduino boards carrying Marlin gives me all I want of features without writing a bunch of macros I dont have time for just to configure simple features

The only thing the duet gives me more from my point of view is stronger drivers and quieter drivers witch is fine if I can get it running with basic features without to much work

I need some motivation to dig into this a second time and not sure it is for me at this point

@bartolomeus

I dont have time to read or fine tune the stalldetect I am sorry

I did get it to work with your settings but experiencing some random false positives and more than one is to much as I dont know when it will happen again so if this is not more stable I want endstops

bartolomeus

I was actually referring to the others advising again at the use of sensorless homing on a corexy. I really don't see the problem.

@pro3d I think that is part of the problem, not willing to spend some time into the board. A basic configuration isn't really that difficult. You probably spent time the first time using Marlin and learning how to compile and flash with arduino, and now you are used to it. It takes a little/the same effort to understand the Duet. If you can't figure things out, there is always a great community behind the duet, willing to help.

@bartolomeus

I think you are right about me not using the time necessary

To get to that point I would like to see clearly what the d3d/rrf solution can give me more? Then use the time to get there - So I need motivation to dig into the RRF hackerspace ones more... (lack of atm)

Probably just listing it if I dont se a good reason to put in the effort

Sell the board, you are clearly not able to change your "Marlin" mindset.
Nothing to see here, carry on...

dragonn

I am pretty sure if you first board would be Duet you would have that problems.
I agree, sell it. If you don't have time don't change something witch is already fine working.

You mentioned "macros". There are really not that many and they tend to be small and simple.

I started with 8 bit Arduinos, I then went with Smoothies and they were a step in the right direction but once I discovered Duets I converted all of my printers and never looked back.

Perhaps you attempted to do a complete configuration as opposed to a step-by-step configuration, testing each "step" as you go.

My config.g file consists of 36 lines. Then there are the 4 "homing" files that total 23 lines but they are mostly the same with small variations.

Those are the essential ones to get your printer up and running.

Once you have the "gestalt aha moment" all will be clear and smooth sailing.

Hang in there.

I guess if i skip the stall detect it would be a much smoother ride. I did have a lot of problem with the BL touch and corner bed leveling + bed mesh leveling and simple filament change with pause and park function

I did want to have at least as many features as from my Marlin config and is just trying to get motivated to give it another go

I know the board is good and it is RRF I struggle with. I wonder what RRF can give me more in an easy way - To me it looks a little unfinished

I will try to hang in there - I have a printer on the way so it might go there in a week or so

Does you printer have bed leveling screws that you adjust manually?

On my FolgerTech FT5 I have them and have not found the need for a Z-probe or the "bed leveling" features of the Duet firmware.

I tested with a simple Z-probe but it told be what I already knew - that the bed was flat and level.

On a delta, yes you may want those features but the hardest part there is fitting the Z-probe. Once that is done in a suitable fashion the macros needed should be quite simple.

On my deltas I have yet to fit Z-probes and have just used the manual approach using a dial indicator but it can be done with a thickness gauge or a "piece of paper".

Yes, to use stall detection homing you need to find a good combination of stall detection sensitivity and motor current during homing that works with your motors and mechanics - unless you buy a genuine Prusa i3 Mk3, in which case that work has been done for you. It's not hard to tune the stall detection parameters, but it's probably easier for a beginner to use endstop switches because they don't need tuning.
