Ah OK understood. Is that extra settings appearing in 2.4 or default values changing? Of course maybe both or something else!

Ok thanks for that:) The temps are now spot on. The speeds look good too. I note that wall speed is sitting at 50% of print speed but I assume that is ignored as inner wall speed is showing correct and outer wall speed is showing correct

Thanks - I did actually try that - not sure whether it was or was not a typo - and it did not seem to make a difference. But I will have to assume I made another error at the same time. So I will redo with double = and report back.

Do you mean packaged? If you want them in the next release for everyone to see & share, make a pull request. Hi @nallath, what I meant was..... When I first load 2.4 release after installation; will my printer definition and my profile settings be there on the GUI waiting for me? Or do I need to do some sort of import process to get them there and visible to me?

Hi @nallath thanks for that. OK I tried it but with mixed success. I set the temperatures as well as the speeds. So I set all the temps = to the print temp. material_bed_temperature = 73 material_final_print_temperature = material_print_temperature material_initial_print_temperature = material_print_temperature material_print_temperature_layer_0 = material_print_temperature And the speeds equal to the print speed speed_infill = speed_print speed_topbottom = speed_print speed_wall_0 = speed_print (but no idea what this data item is referring to) speed_wall_x = speed_print (but no idea what this data item is referring to) What I got was Temps With Printing temp set as 250 material_final_print_temperature = 235 material_initial_print_temperature = 240 material_print_temperature_layer_0 = 255 ( I assume this is “Printing temp/. initial layer”) So they are all wrong and should be 250. Speeds With Print speed set to 70 speed_infill = 70 Correct!! speed_topbottom = 35 speed_wall_0 = do not know what this is speed_wall_x = do not know what this is The Cura Print setup display showed Wall speed 35 Outer wall speed 35 Inner wall speed 70 Correct!! I also note, strangely, that if I go to the Profiles dialogue page, with the two columns “Profile” and “Current”, I see under Current Printing temp = 250 correct, input by me Printing temp initial layer = material_print temp + 5 Incorrect! Initial Printing temp = max_-273.15, material_print…. -10 Incorrect! Initial Printing temp = max_-273.15, material_print…. -15 Incorrect! Print_speed = 70 Correct, input by me Infill_speed = speed_print Correct! Outer_wall speed = speed_wall Incorrect; speed_wall is not listed in my .cfg file Inner wall speed = speed_wall *2 Incorrect; speed_wall is not listed in my .cfg file Top bottom speed = speed_print/2 Incorrect, this is not what I input into the .cfg file

Yup, with the exception of the initial layer, I have always printed with the print speeds all the same to ensure the quality of the perimeter wall. If I do have a piece with a filled large x/y geometry then I may push up the infill speed for speed purposes, but if I do I will probably add an extra wall or two to protect the perimeter wall. IMHO a consistent pressure to protect the perimeter wall is one of the best things you can do if clean surfaces are important to you.

Oh dear, as much I like and respect my American friends they owe a huge debt to the rest of the world for exporting their litigation culture. We have had to endure litigation of our troops returning from the middle east, which fortunately the Government has just acted on, and a real serious issue (politically) right now is litigation against the NHS. Both of course dwarf the UM warranty point , but it is still a bad move and poorly thought out and wrongly worded.

Let me throw something else into this. I currently have a dual extruder printer which is not UM so maybe Cura does not understand that it is a dual extruder and is happy to let me print "One at a time"??? But I am sure that under 15.04 there was a extruder offset parameter in the printer definition which would mean Cura 15.04 knew it was dual extruder - I may be wrong but I just have this memory. Maybe I should reinstall 15,04 and check

Lol read my latest post on the other thread, I suspect we are confused:P

Hi @nallath I am now a bit confused and not sure if I have read your posts correctly. In your post at 9:17 you are I think saying that with our dual extruders right now we cannot print One at a Time, even if we are using single extrusion for the print. In your last post at 10:52 you seem to be saying that we can print multiple objects. Yes "One at a time" does have limitations but for me, especially running a business, "One at a time" is vital. Let us say I am printing 8 pieces with a total print time of 16 hours and I have a failure 80% of the way through the print. With "print all at once" I have 8 models to throw in the trash can. With "One at time" I have 6 models to sell to my customer - not a difficult decision to make on which way to print 8)

Having just read another post on the now multiple versions of extruder temp., maybe Extruder inheritance could be implemented too?

And how about reinstatement of Print speed inheritance, present in all versions of Cura up to 15.n and then dropped from 2.n Like many others I am sure, with the exception of the 1st layer speed, all my printing speeds are the same. This ensures a consistent pressure through the extrusion system with the benefits one would expect on surface finish. Just occasionally, if I have a large x/y dimension I will push up infill speed. Now, without Print speed inheritance, every time I change the Print speed I have another 3 or 4 speeds that need changing. OK not the end of the world but extremely irritating especially if I am testing to get the optimum mix on a new part of surface quality and speed of production.

... I have looked but cannot see any install instructions for 2.4 Release

A couple of questions on how to install with 2.4beta 2 currently installed. 1 Can 2.4 Release be installed over the top of 2.4Beta2, or should one uninstall 2.4 Beta 2 first. 2. Can the Appdata\Cura\quality & machine_instances folders, for settings and customised printer definitions, be left in place, or should they be backed up? 3. What is the method to get my settings and customised printer definitions into 2.4 Release, assuming if needed that I have copied them back into the Appdata\Cura folders? Windows 10 laptop

How come something like this is under development when it is actually not really a problem, but allowing people to print multiple models in one at a time mode, which they have been doing, has been removed from the software????

Damn and blast, 2.4 release is out!!!!!!!!!!!!! Another backup and install to do

Hi @nallath, sorry no can do. As I said in a few posts above 2.4b2 died on me and during the process of reinstalling then deleting and installing 2.3 I lost the log files. As it happens on Sunday Windows 10 died on me and after 10 hours or so I gave up and today had to spend eu500 on a new laptop :angry: So I now have 2.4 installed and running again. If the problem with the customised printer defn. happens again I WILL send the log file.

Thanks - but first to avoid any confusion. The original post and mine too was referring to the scenario where a printer with dual extruders is doing single extrusion printing -there is no need to run extruder switch code in this scenario. So is it possible to allow us to do one at a time printing if dual extrusion is not being used? Also, importantly, if you were to provide functionality where we could identify the sequence of the models to printed, we could layout the models on the print bed to ensure there was no collision - e.g. laying 5 models in a diagonal line from top left to bottom right and numbering them 1 to 5 starting at top left.

err my machine is dual extruder. Sure it is not a UM but what difference does that make? Surely it is all about excluding the print heads from an already printed model and the Add customised printer dialogue has the relevant measurements for the software to do this and it does. Or maybe to be accurate 15.n did, I have not had a need to print one at time under 2.n yet

Oh dear looks like Ultimaker have just lost a probable order, unless they can manufacture and warranty customised PLA like Faberdashery and Colorfabb do.

The time it will take you to print a 3 Dmodel depends on two factors, the print speed that you use and the thickness of each layer (aka the resolution). A higher print speed makes it faster but reduces the quality on most things. The thicker the layer makes it faster to print the model but reduces the quality. If you want to go into business then you will presumably need to produce parts that have a good quality and therefore it matters not which of those two printers is the fastest, you will never use those quoted maximum speeds.

I use 5.5mm and 6.5mm.

@ahoeben Why for the UM3 but not other printers?. Not sure I can see why it works with other printers (which I have) but not the UM3 which I am considering. When printing multiples I nearly always use 'Print one at a time'

Sorry just reread and you lower & fatter, so it is thinner at the top! You will have a setting set for minimum layer time. As you get closer to the top this will automatically lower the print speed - which you need otherwise the layer print time will be too small and the layer you are printing will be printed on the previous layer which will still be soft.

Ok it depends on what context you are using the word Conus. Is your Conus fatter at the top or at the bottom?
