Hi all.

I put my printer away last year after getting everything working, didn't cope well with lockdown, but started rebuilding a guitar instead. That's finished, so back to the printer

My question, I have the final version of RRF2 installed. Will I get any benefit by migrating to RRF3? It's just a mini delta.

Hi @Dugee
I'm in almost the same position as you.
It's been 3 years no_printing and I restored vintage saxofones until I ran out of materials...

I hope to find a summary, of what's new in RRF3.x
The efford to re-invent my config.g must be worth it...

its not that much to do.

we should start a music channel in here to compare lockdown, non, 3d projects!@o_lampe

[Dugee]

@Veti Well, i priced the components for creating a d-bot last night and it seems I can get everything I need for about £200 and then I would definitely migrate to rrf3.

And then I could probably make one!

The main advantages are more flexible pin allocation, and conditions and loops in GCode.

[Dugee]

@dc42 is the delta calibration algorithm the same, 6 factor still being the most appropriate?

I've printed an American Native flute and I also have made a Didgeridoo with my own mouthpiece, so...

I remember we've discussed the benefit of conditions back in RepRap-forum, but I don't remember, what I wanted to do with it.
In general, for a single nozzle 3D printer, there's no need to update?
I have another DuetWiFi and a Maestro in spare, so I could give it a try.

the "best" is the one you get the best results with.

what the factors calibration do has not been change from 2 to 3.
see what they do here

That sounds like a pi$$ing contest, nooo I pass
(and I would win hands down, no doubt)

[Dugee]

@Veti true, I tended to use 6 until I got a stable calibration then reduced for actual printing.

I
With RRF3 is it possible to create something that will do the probing for the bed.g probe trigger heights and automatically populate the file or is it still a manual process? that was the biggest PITA that I had, and with the printer sitting so long I will need to basically start from scratch to calibrate.

I couldn't see anything obvious other then this still being referenced in the Delta Calibration steps. I didn't go through the full differences to RRF3, and what the conditional processes can do, just looked the process for migration, so apologies if this is a question answered in the dozuki.

[Dugee]

@o_lampe mine was just lutherie type stuff, woodwork, painting, electrics, so if you we get to 3d instruments, you've already won.

the configurator will generate a bed.g for you

[Dugee]

@Veti yes, it's just that previously to determine the trigger heights ( 3 underbed sensors for hot end probing) it felt like it took an age to probe, get the results, put them through a spreadsheet to get the differential to origin, then input into the bed.g file for the probe points. I had created a file to probe all of the calibration points 5(?) times to then average the trigger height in a spreadsheet which I then put in to bed.g manually.

When I was looking before at the conditional g-code I remember some talk of being able to use <average> but cant find anything in the forum, Probably not using the correct search terms.

I think the configurator is a great tool, but I havent been in to it for a long time. I'll have a look to see what has changed,

[o_lampe]

@Dugee
yup, I gave up dealing with underbed (piezo) sensors.
On my XXL-Delta I have Davids smart effector which gave me the best results so far.

There's a printable Ukulele on thingiverse, just saying....

[Dugee]

@o_lampe I looked at that, with the amount of work involved in putting a smart effector into my machine it isnt worth it.

It's only a Mini, and one of the reasons for getting the machine back out is to print the pieces for a D bot, as I think that will be more useful for what I want to print.

I can just print everything I need on the mini, it's tight but it just makes it.

[Dugee]

@jay_s_uk I saw that one, but it doesn't automate the trigger heights, but the calibration process.

I did see a thread that included automating the trigger heights,

https://forum.duet3d.com/topic/14280/invitation-to-share-your-conditional-gcode-scripts

but havent yet found any follow up.

I also found this one, which I'll have to read through first!
