@deckingman Thanks for the reply!

I agree with you and have tried to get a perfect point where print speed, flow rate, and tuning settings give the best scenario. I set up another test print 80mm high with 1mm layer heights. Then I set the number of slower layers to 79. As the print speeds and flow rate increased with each layer I found that there was a sweet spot (see image attached) where the start and ends of extrusions worked well and there were no gaps. This doesn't shower solve the issue of short infill lines, which are still terrible.

These results are with the following settings:
*Retract/Reprime length 0.50/0.70mm
*Pressure advance set to 0

Unfortunately, infill prints still look terrible. Ill try slowing them down a lot.

I have attached the config file plus two more images of another test print to conclude max flow rate. You can see in the images where the print starts to suffer, which corresponds to 57mm3/s.

I have tried a range of temps and volumetric flow rates by changing the print speeds in Cura. Short quick lines are the issue with this setup, long lines (around the edges in Flow rate test part) work well with little to no defects, even at high speeds and flow rates. The issue is I need infill and this causes the issues you see in the images.

Either way, I've wasted too much time on my own. I need help config.g

Hi guys

I did some serious upgrades to our Creality CR10 Max, but do need help with fine-tuning.
Upgrades:

• Bondtech LGX large gears extruder
• Mosquito Magnum+ Air, with two 50W Mosquitos heaters
• Bontech high flow CHT nozzles - 1.8mm nozzle is the main aim
• Duet Mini 5 + Ethernet, PanelDue

I have successfully printed very large and strong prints (approx 350mm in diameter and 450mm in height) in a fraction of the time it would take with a 0.8mm nozzle and standard parts. I have attached 3 images, two of the test part that I have been trying to tune and 1 of one of the finished prints currently in use.

Issues so far:

• Gaps between infill lines - see circles and infill gaps.
• Extrusion - excessive material extruded, nozzle ends up bouncing over the print when moving.
• Stringing - I think related to above and temp

I have tried a range of combos using @Phaedrux macros, however, I can't get a base that works. I am hoping for this to be a constructive discussion

I would love to end up helping others who would like to try this out. My next "printer project" is to do the same upgrades to an Ender 5. Parts are currently sitting in the cupboard

@phaedrux I emailed Duet and was advised to go to the forums for a support staff to review fault and authorise a warranty claim.

@phaedrux I bought it recently from Filastruder - 12 July 2022.

Please can someone from Duet help me with a claim for a new one? Ive had to buy a new one in order tog et prints going. Quite frustrating.

Hi guys

We have the following issue with our new board - https://forum.duet3d.com/topic/19447/new-duet-2-wifi-not-reading-sd-card

Please can someone get back to me regarding a replacement or solution? It has cost us ALOT of time and frustration to get to this point.
