Quote626Pilot Quotedc42 Yes I would like to wrap the messages to at least 2 lines, but I have more pressing work on the PanelDue firmware, in particular I have two users who need support for more than two extruders. I migrated from Smoothie to the Duet platform because it has hardware support for 3+ extruders. Is that not working yet, and if not, do you have a rough ETA?

Quotedougal1957 Quotedc42 hercek, thanks for that. Where do you get your steel core belts from? Dave Found these and ordered some PU GT2 with Steelcore HTH Doug Same as I ordered, only I got it $1.39 cheaper, probably due to ordering via their app. (They run some promotions to use their app sometimes)by Koenig - Delta Machines
Quotedc42 I use GT2 belts that are nearly 2m long on my 1m high delta, and I haven't observed any problems that I can put down to belt springiness. So I am not convinced that you need to avoid using belts. I see that you can get GT2 belt in 9mm width. Why not use that, assuming you can find compatible pulleys? The extra 50% width would reduce the springiness by 1/3. Not that hard to find GT2 belby Koenig - Delta Machines

QuoteVlerherg I cannot recommend the E3Dv6 hot end enough. It is the Cadillac of hot ends, to be sure. I use them on my other two printers and have not regretted it for a moment. I will eventually pick one up for the Kossel as well. There are users that has indicated that the "all metal E3Dv6" gives you some trouble when using long bowden tube and printing PLA, so depending on what you plan to uby Koenig - Delta Machines

Didn't look at the model you tried to print when I wrote my first answer, now I have. That looks pretty "advanced" to print. You are going to want to look into adding support for that model as well. A skirt is useful for priming the hotend to make sure there's plastic lined up when the actual print starts.

Quotedavidf01 QuoteVlerherg Quotedavidf01I would love to try printing some flexible material Flexible material is very fun to print with, but can be a headache as well, especially with a bowden setup.

QuoteTennysballs Since the problem was persisting, I jumped into the firmware(Marlin) to look around. I'm using 16th steps. Since I am using Rich's spool design from his 3DR(and his default steps per unit), I double checked to see if maybe he was using a different step rate and if changing it would make a difference. I couldn't really find any solid information on it, but it seemed that he mightby Koenig - Delta Machines
Quotedc42 QuoteTennysballs So this kind of sucks. But in a way it's good because it's something. So I tuned my motors to ~480mv Vref using the following data.

Nothing obvious in that, as far as I can tell. Very high maximum speed though >300mm/s and a bit odd steps/mm, not using pulleys/belts? The M666 values look a bit odd as well, >5mm really much. Which version of the firmware are you using?by Koenig - Delta Machines
QuoteSolderSucker Hi all! I've got a strange problem with my mini kossel/duet machine when calibrating, and I wondered if anybody else had come across it. Now to my thinking, I should be able to just drop the hot end using M665 H by 0.05mm and the job should be done, right? However...ANY adjustment of height using M665 results in the hot end moving anything between 5 and 20mm above the bed whenby Koenig - Delta Machines

Quoteo_lampe I don't trust the wiki-formulas regarding the DRV8825 too much. I had a DRV8825 running stable at 2.4V on a 1.7A stepper. Regarding the formula, this would have been 4.8A ?!
