Hello again! Just wondered - you just needed the Duet 3, and the toolboard, no other expansion boards? And a panel due?
Was there any weird wiring you came across? I think I'll go down the same route at the moment.
Best regards, Mike
@luke-slaboratory First of all congrats on the new job 😉 hope it's something you like. No need to be sorry, family and personal things come first 😉 I can thank you for the work you do and can say lots of people appreciate it and we are glad that you work on this. Thanks for the update and will stand by and looking forward 😉 Stay safe
@joergs5 yeah I've hit the hot end thermal limit on my 0.6mm volcano where I'm getting temperature drops, however the new beta firmware has extruder temp feed forward so I'm hoping that'll give me some more head room. I'm already printing pla at 245c to get better thermal transfer.
@dc42 Thanks - whatever was fixed with heater faults in 3.4 exposed the issue and we've suspected it was a configuration issue. After a quick review, I think the missing R value is the culprit. It has been added and we are now performing additional testing.
It's often the little things that make life difficult: My extruder didn't make a sound on the 1LC and, as is always the case, you first check the crimp connections, the cables, the correct connections, the configuration - and everything several times. One is almost inclined to rebuild everything again, then one reads the last of countless articles and realizes that it was only a small parameter... Like above with the fan.
Go look at Octoprint, where it's much easier to select an object for printing, the file view is automatically updated on upload & selected for printing, preheat, & start printing.
There is the 'upload and start' button in the top right of DWC. I almost always use this when kicking off a print, even if I know the file is already on the printer somewhere. It's easy and sets the print off straight away. Not sure if that helps?
The Duet3 boards use a step clock of 750KHz we use (as in STM32) 1MHz the Duet 2 and Maestro boards use 937.5KHz. This gives a min F value of 5.72, 7.63 and 7.15 respectively. So I suspect that the Duet 2 and Maestro won't work with an F value of 7 either
You therefore may want to consider upping the default frequency to 8
@wieman01, can you improve the properties of the clay? E.g add water?
Yes, you're right, in principle that is an option, however, in our case the viscosity of the material we are using cannot be changed for various reasons I won't bother you with. 🙂
I have order a geared stepper, let's see if that works out for us.
Hi, reference style testing has been made with D1.75 PLA filament, E3D nozzle D0.4mm and Brass and Stainless steel Hobb-goblin gears, all metal extruder with a gap limiter, spring force approx 2kg adjusted to set gap of 1.3mm with CNC machined Aluminium all parts and a steel ball bearing idler. Inlet side fully a PTFE tube, very low pulling force. Distance to nozzle approx 40mm from gear. Cold-end side measuring 36-42°C and hotend 205°C PLA. PA range tested 0 - 0.16, and for PLA it works best between 0.04 and 0.06 only (still remaining dimensionally accurate enough).
What makes it worrying is that if looking at motor movements with slow-motion camera, it appears as if motor is not moving at start after un-retraction moves. But this will surely need to be checked with a encoder still. Please note that in middle of print, performance of PA seems to be very good in corners, and perimeters, but all problems seem to be related to retraction points and infill start-end points.
@pcr Being Z=0 after applying the mesh correction, the Z=0 limit calculated is below the bed surface. So it adds more travel to Z axis when mesh is loaded.
Without mesh correction the probe point and the nozzle point Z=0 is correct. We test precision and repetability of Z probe and Z lenght switch and it is consistent, so could be causing innacuracy but both are correct.
Tested with a 3:3 grid, 9:9 grid and 20mm G29 grid gives the same incorrect compensation.
We will try to update to latest beta 3 and look for diferences.
