I will be reading that tonight.
I might have learnt something as well.
Either the extra temp or more squish has worked.
I am pretty sure it was the nozzle temp actually in cura that I increased that did the trick.
I have never had to alter nozzle temps but that could be because the machine profile had a higher temp to start with.
It could be the nozzle heater is better on my Ender 3.
Whilst I was waiting for replies and the test print on the Ender 3 max I printed a 3 x 2 x 1 box for the gridfinity system.
First it took 7 hours....wow.
But I then saw it had printed with supports inside and underneath. Probably as I printed with supports last time I sliced for the Ender 3.
I also noticed it suffered lack of bonding and delamination. So I will try it again tomorrow with increased nozzle temps.
In the meantime more reading....

It can be the hotend sensor itself calibrated different from machine to machine too. I had a sensor go bad (well I broke the fine wire as it entered the hotend...) and had to fit a replacement, and I had to reduce my nozzle temps by 5c to get the same hotend temperature as measured with a thermometer.
I suspect cura is the same as prusa in this respect, but the default speed for non prusa (or ultimaker) printers are snail speed slow. I think slicer makers go with really conservative settings for printers from other brands apart from their own, and maybe they pick the speeds because its better if it works for everyone even with badly tuned settings and issues but is dog slow. So now the fun bit after getting it printing right is seeing how far down you can push the pedal...

Yep the biggest issue though is printing the boxes. 7 hours for a 3 x2 x1 is way too slow. So I need to address the supports issue and let them keep printing while I get on with other things.
Have I ever said I really can't multitask.

Maybe by looking at the flow (extrusion) rates but I'd have to look up what they should be for different nozzles.
I have a couple of ender 2 and one was set up for ABS pro and for some reason I think it might be a 0.8 nozzle.
I guess it's a lot easier to unscrew it and look. Lol
Been busy testing today but managed to get some good intelligence on what's working.
As its for gridfinity boxes and bases the extra temp is really making the difference. It would be nice to get a little more speed as it's only doing 50 currently.
How these guys show 100's of printed boxes on their YouTube channels is beyond me. I am even pressing my old Anet AM8 into service along with a couple of Ender2's.
I wonder if an xc1 would be quicker than all those printers running at once for the same output.

My P1P is approx 4 times faster. I had to prove that to myself by printing some boxes I had previously printed on the Ender 3.
I found it amazing that something that had taken 8 hours now prints in two!
It's funny that if I slice something and it is more than a 4 hour print, I will make changes to the infill etc to drop it down as I just don't want to wait that long anymore!

That was the same with my Ender 3 V2. However the K!-MAX defaults to 300 and I don't often have to reduce it.
I have my ender5-plus set at 300mm/s max velocity currently with the stock v-wheels and cartesian layout but modified hotend/extruder and frame stiffening and klipper firmware, and I hope it can go even faster with good quality when I finish the next round of mods. Be interesting to benchmark it when that's done!

I have an Ender 5 plus that has been sat in my shed since it kept losing its X y coordinates. Can you put different firmware on the standard board? If you can, perhaps you could enlighten me so I could resurrect it. I miss the large bed and don't mind slow prints if they are huge!
Even 2 hours a box ,to get the amount they show it must take months.
Ironically the Ender 3 max is now printing better than the Ender 3.
A 1 x 1 x1 gridfinity box is taking 2 hours 6 mins.
Does klipper increase the effective printing speed of an ender 3?

I think a lot of YouTube channels have many printers but just don't show them. They even may outsource if they think the revenue raised from the video is worth it.
Or as you say, it takes months and they just don't tell you!
I am thinking of getting a second P1S as I am doing more industrial printing for prototypes atm. I do have to be careful I don't make too much as I don't want to be vat registered. This is, after all, just a hobby!
I think its important to understand its not just a firmware you stick on the printer and carry on but two different devices.
My ender5-plus has klipper firmware on it on the stock 4.2.2 creality board it came with which turns the printer itself into a zombie controlled by the host only, no control via the front panel at all and the display just shows the boot splash screen permanently, so you need a second device to run klipper host on (a pi or linux tablet etc) that connects directly to the usb port on this version of the ender. The idea being that the interface and UI and heavy lifting is all done by the host, leaving the oem board free to just be a controller for the steppers which is why it is so much faster. The host has a octoprint style print preview, uploading and queue for prints, integrated cameras that you can set up for timelaps or live monitoring remote and a bunch of other features.
Creality themselves sell their sonicpad tablet that comes with klipper host and will reflash the printer as part of its initial first start process if you want the click and go solution. Here's their blub https://www.creality.com/products/creality-sonic-pad and as usual with creality, the prices dip considerably in one of their many sales (they were 84e in one sale this year)
I was going to use a beaglebone sbc as the host, then I got a sonic pad gifted me so that's what I'm using and, much as I like to make things from scratch its pretty slick to be honest.
ukracer, apparently you can run at 100mm/s on a ender3-max with no hardware changes and good quality.

Cheers for the reply. I don't want to give Creality any more money (for reasons I won't post here) but I have a spare Pi 3 that would do. I will give it a go and see if I can get it working.
Sure, and I totally get that stance having bought from them too. Just took this pic to make it clearer for others. You can see the printer sat there at boot splash with all the info on the pad's touchscreen for local control, and it exposes a webserver on the local network for remote control (which is better than the touchscreen ui).
How about using an i5 mini pc instead of a pi?
The sonicpad is just a linux based arm tablet with python installed underneath the branding, its even listening out the box to ssh with a default user called creality with a default pw that can ssh in 
It depends on your personal level of linux knowledge how smooth that's going to be to use a mini pc though. With the pi based host, its just a image you stick on the pi so easier all round.
From their faq at http://www.klipper3d.org/FAQ.html
The recommended hardware is a Raspberry Pi 2, Raspberry Pi 3, orRaspberry Pi 4.
Klipper will run on a Raspberry Pi 1 and on the Raspberry Pi Zero, butthese boards don't have enough processing power to run OctoPrintwell. It is common for print stalls to occur on these slower machineswhen printing directly from OctoPrint. (The printer may move fasterthan OctoPrint can send movement commands.) If you wish to run on oneone of these slower boards anyway, consider using the "virtual_sdcard"feature when printing (seeconfig reference for details).
For running on the Beaglebone, see theBeaglebone specific installation instructions.
Klipper has been run on other machines. The Klipper host software onlyrequires Python running on a Linux (or similar) computer. However, ifyou wish to run it on a different machine you will need Linux adminknowledge to install the system prerequisites for that particularmachine. See the install-octopi.shscript for further information on the necessary Linux admin steps.
If you are looking to run the Klipper host software on a low-end chip,then be aware that, at a minimum, a machine with "double precisionfloating point" hardware is required.
If you are looking to run the Klipper host software on a sharedgeneral-purpose desktop or server class machine, then note thatKlipper has some real-time scheduling requirements. If, during aprint, the host computer also performs an intensive general-purposecomputing task (such as defragmenting a hard drive, 3d rendering,heavy swapping, etc.), then it may cause Klipper to report printerrors.
Note: If you are not using an OctoPi image, be aware that severalLinux distributions enable a "ModemManager" (or similar) package thatcan disrupt serial communication. (Which can cause Klipper to reportseemingly random "Lost communication with MCU" errors.) If you installKlipper on one of these distributions you may need to disable thatpackage.
