Re: Stock Max v3 Motors on 24v?

Great info as usual, thanks. I never thought of this to need calibration ;-)

Optimizing Duet setup regarding stepper current, jerk and speed

Oh, I forgot to mention: it almost does not fray when you burn the ends a bit with a torch, and it completely does not fray when you use a hot-knife for cutting! I used "F6W0.38 Flexo F6 Woven Wrap, 9.5mm" for both the loom and the outer PTFE wrap. If you have extra wires in your look and ...

Re: Techflex sleeving

Yeah I thought about shrinmking the end of the tree, but I did not for 2 reasons: A) My tube did not fit over the connectors and I was to lazy to resolder them B) I am thinking about a LED ring so I will need to put in extra wiring soon ;-)

Re: Stock Max v3 Motors on 24v?

Higher current will reduce the likelihood of missed steps. However, if you increase the current much above the 1.2A that you are already using, then you will need to use a fan to cool your Duet 0.6 board. The best arrangement is a fan that blows cool air along the line of drivers on both sides of t...

Re: Rostock Max v2 Jamming

Hmm, that still leaves the bore length as a possible cause. Another option would be that your hotend temp is way below what the thermistor guesses. Have you checked that against a thermo couple?

Re: Rostock Max v2 Jamming

The stock fan works just fine if nothing is obstructing the airflow besides the heatsink of the E3D. Mostly 2mm retracts work fine, but maybe there is some specific circumstance where you would want to try 1.5mm. If you push in the PTFE tube, usually you will find a first barrier 1 or 2 mm before th...

I am pretty thrilled about this Techflex sleeving, I used to have a foldable sleeve with velcro for closing them up. It is nice to be able to take the sleeve off and be able to work on it, or add something to it. But I always felt it was putting too much strain on the hotend mount, ans it was tiltin...

I know from experience that a cross-wind can be carried many meters into the spool before it becomes a problem. I don't want to put the blame on your own side, but I cannot image that these spools are getting hand-winded, and I don't see how automatically winded spools could become crossed. It sure ...

That is a nice catch! So every next gridline is going high or low by turn. Curious...

After you repeat the mesh grid compensation routine, it would be interesting t...

Re: Height map issues

Most mechanical problems get exponentially bigger the closer the Hotend gets to the edges of the bed or the towers. It is not very uncommon to make the calibration radius smaller than bed. But still it is probably a mechanical problem. In your first picture I see some kind of rippling effect perpend...

Re: PEI Print Surface How To - recap

I think most of us print PLA around 60C and ABS around 90C. Important is to give your bed time to even out temp, and let the surface reach the set temp (PEI is an insulator!). So do not start too quickly after starting the heater.

Well, it could be (a bit) quicker as well as more consistent than the paper-drag method, and more easy to perform before each print. But you're right, it doesn't add much until you get a Duet.
