If I'm understanding what she's saying correctly, Lindy turns off her print bed heater when printing semi-flex. https://youtu.be/8XVWKrvwg14?t=156 So perhaps that would work for you?by asbo - General

QuoteSrek QuoteDust There is zero reason to port marlin and waste time and money and resources when these other better firmwares options already exist.

Yes I read through that when I first started modelling it. It's been a while since I looked at it, so maybe I'll try again. It just occurred to me that I said I'd do it and then hadn't delivered.by asbo - General
Looking good powdermetal Sorry I haven't posted the SolidWorks conversion I said I would, I got frustrated and gave up because I could never get the formula to work properly.by asbo - General
I agree with everything DjDemonD said and especially this: QuoteDjDemonD you seem to be attacking the idea of innovative people being able to get a return for their time and effort. I buy stuff from Mutley3d, I buy stuff from E3D, etc, and I'm happy to support companies that deliver quality products like they do. It's especially nice when they're ploughing that money back into their company and cby asbo - General
After a bit of experimentation I've found that my nozzle was too close to the bed, PETG apparently doesn't like to be squished at all. It's printing a lot better now and barely needs a tap to free the print when done.by asbo - General
If you type PEI sheet into ebay.co.uk you get a few listings, some in the UK and one in Sweden. I feel I should point out that PrintBite is cheaper and works like a dream on every filament I've tried so far.by asbo - General
I've used dold-mechatronik a couple of times, good prices, pretty quick delivery from Germany and since we're still in the EU no import duty. Their website is in German but they speak English so you can email them info@dold-mechatronik.de and get a quote.by asbo - General
I've been using PETG with printbite and it sticks down well but doesn't self release when finished. So you do have to get in there with something sharp and thin to get it off. As far as I can tell it's impossible for chips to be torn out of the printbite like I've seen happen to glass beds. The stuff I'm using is Reprapper Tech PETG which I bought from 3d filaprint, although they don't seem to beby asbo - General
QuoteDADIY Please can we have the option to disable the safety checks. After several days of printing I get random errors on the bed heater or the hot end which go un noticed for a while as the printer keeps printing in the air but wrecking a meter of a filament each time as the extruder can't push it through a cold hot end. I'd like this option too, or at least have the print pause.by asbo - Duet
Oh that is good news, now I know I probably won't kill my Duet wifi like thatby asbo - Duet
Quotedc42 I'm glad you solved it! That's one less thing for me to investigate. I really appreciate all your work on the Duet and whatnot, don't burn yourself out though! I'll try and remember to update this when I get it hooked up to the printer. I might use some thermally conductive electrically insulated thermal adhesive stuff to keep the junction in its cartridge if I think it needs it.by asbo - Duet
I yoinked the cartridge tube bit off (the ones I got don't have any heat shrink like they do in the listing photo) and the braid completely covers the junction. So I trimmed the braid, wrapped it and the junction in kapton tape and pushed it back into the cartridge tube. That seems to have solved the problem I've not tried heating it up with anything but body heat so far but it's reading the coby asbo - Duet
I'm getting 13ohms between the cartridge and the positive wire, and 9ohms between the cartridge and the negative wire. If I measure between the braid and the wire at the terminal end I get a couple of ohms increase in resistance. I think that means the connection between them must be at the cartridge end? I'm going to disassemble it and see what's what.by asbo - Duet
No they're actually from aliexpress, for just over a pound each I thought they were worth a try. I cut the two terminals off one to see if that made any difference and it didn't. The wire underneath is single core, I assume it's going to be the same all the way to the thermocouple? Stripping off that metal braid stuff looks tricky.by asbo - Duet
I use SolidWorks and Cinema 4D, I've not found anything that either one or the other can't do. I've not tried it and I don't know how it compares to zbrush but you can sculpt and paint textures within C4D if you have the bodypaint module.by asbo - General
Well it's in a 3mm diameter cylindrical housing so I'm assuming it is, how would I check? Either way, I didn't mount the other thermocouples I tried into the heater block so it couldn't have affected them. I've switched back to the thermistor, for the time being, on the 0.6, but I'd like to get the thermocouples working on the Duet Wifi.by asbo - Duet
After having switched back to the Duet 0.6 I thought I may as well install a thermocouple whilst I have the printer apart, but I'm having problems. The temperature reads correctly but randomly jumps up to 2000c every few seconds. If I try to heat up the hotend I get a 'slower to heat up than expected' fault. I've tried different thermocouples and different MAX31855 boards, which I soldered the neby asbo - Duet
That sounds good. Quotedc42we haven't risked testing it yet. I'm sure some idiot like me will 'test' it for you soon enoughby asbo - Duet
After some thought I think it must have been a short between the +5v I use for the always-on cooling fan connector and, as you say, the ground on the thermistor connector. I got the idea to use dupont connectors so I can easily swap between a V6 and a Volcano from Tom on Youtube. I chose to use female connectors at the hotend end of the cables like he did, clearly this was a bad idea as the maleby asbo - Duet
This is my Duet 0.8.5 and it just died a smokey death, but I don't know how. The printer was on and I'd just used it to heat up and do the nozzle hot tightening on an E3d Volcano, I'd then disconnected the hot end and was fitting it to the effector when I heard a crackling noise and the Duet let out it's magic smoke Link to image Based on the photo does anyone have any idea how I killed it?

Thanks for the file Mating: Apparently the way Cam mates work in Solidworks has changed since that .pdf guide was made, the cam mate must now be a continuous surface. So the gear with it's 0 - 180 degrees equation driven curve and it's mirror can't be mated since Solidworks doesn't see them as continuous. I got around this by fitting a spline to those two curves, although a spline is inaccurateby asbo - General
This is what I've modelled so far. Spent far too long messing around trying to get the gears to mate properly, which is kinda pointless but oh well @powdermetal Could you upload this part with the chamfers and fillets disabled/removed please? I'm finding it too difficult to reverse engineer.by asbo - General
+1 For my observational skills That seems a proper weird thing for aliexpress to do though.by asbo - General
I would say that's nonsense, somewhere like BST, for example, would be forced to close and would surely have a notice on their store page. Considering the vast quantities of ballscrews and bearings on aliexpress they'd lose out on a lot of business.by asbo - General
Maths isn't my strong suit so those equations mostly go over my head, but I can punch the numbers into the software easy enough I'll have another go at it tomorrow.by asbo - General
I think the software we use handles things differently, here I've put in the numbers you gave(blue line), then offset it by 2mm(black line). Then I've overlaid the STL file(orange) and they don't line up. If I use R=16 it lines up perfectly though(without an offset).by asbo - General
Quotepowdermetal Redesigning is still the best CAD translation method - haha very true! Thanks for the info.by asbo - General
I'm now drawing them up. @powdermetal What numbers did you use for the rollers etc in the equations as shown here ? R is obviously 15 and N is 11 for the ExcenterGear but E and Rr I'm not sure about. Those values for the RingGear would be handy tooby asbo - General
