Duet3 stuff on show at TCT - 6 years ago

AS title says pics are at Duet3 teasers all I can say is WOW can't wait Seeing Nema 34 motors driven at 3 amps was impressive and to find that the drivers can do 4 amps and maybe more video of the system at Duet3 system Video

Re: A plea to firmware developers to use common GCode standards - 6 years ago

Quotedc42 There are at least six open source 3D printer firmwares in common use, and more if we include open source CNC firmwares. The RepRap movement has been a success in part because of healthy competition between different firmwares, with users able to switch between firmwares according to their needs. Therefore it is vital that all firmwares support a common core GCode, and that a given G- o

Quoteormerod168 Quoteredblunt But I got questions to your IR sensor: does it work in the dark? Yes QuoteDoes it work on a black surface too? works just fine on BuildTak (can't recommend BuildTak though, the glue fails) Erik And you ideally want a surface devoid of any logo's printing etc but black is the recommended surface to probe on with the ir sensor

Quoteredblunt having another look at the machine running 10min long i found this: and a little metal flake on the duet. I remind having seen a burnt power mod before. Unfortunatly i cant find this spare on reprapLtd. If it is just the connetor burnt then you should be able to remove it and either replace with a new one or just solder the wires directly to that adaptor board alternativly swap

Re: heated bed false thermal runaway issue - 7 years ago

is there possibly a max bed temp setting somewhere that you are hitting if so you may need to increase that a little to allow for your bed to reach your set temps?

QuoteAdrenalized I'm starting to run out of ideas. My printer started stopping mid print while running marlin 1.0 . So I thought i should upgrade to the marlin 1.1.5 firmware (my thinking was Simplify3d was having a problem with my old firmware plus Repetier host wouldn't work at all) This did not fix my stopping mid print problem. however Repetier host did start working.... small victory's.

Re: Incorrect bed and hot end temperatures - 7 years ago

Yep that's the std symptom of incorrect sense resistors you may also have to adjust your B Values don't touch the R values you can also adjust the S and H values I think they are but you can now also autotune the Heaters go have a look in the Duet3D forums for much more info Duet3D

by dougal1957 - Ormerod

Re: Incorrect bed and hot end temperatures - 7 years ago

Check your M305 lines in your Config.g if the R value is R1000 change it to R4700 this is the sense resistor value and was changed for the later boards.

Cant remember that fact tbh honest but you should be able to determine whaich is the wider opening in the plastic bit and that goes onto the ball first! When it comes to do you jig you dont really need a printed part at all I just used some M3 Setscrews and tee nuts in a length of the extrusion but try and keep the temp environment the same for all the rods to couner the expansion of the ally ex

you will not be able to get the lengths spot on if you thread them so go for 4mm ID tude and epoxy the screws in after attaching the Rod ends so that you can get them the same length

QuoteFA-MAS Pretty standard so far. Now here's where it gets a little more interesting. I plan on using the Robotdigg carriages at least for now. They have a 20x20 hole pattern for mounting to the bearing blocks. The problem is that the Igus bearing blocks have a 20x15 hole pattern. Now I know there are aluminum carriages out there that have the 20x15 hole pattern, but they don't have the be

Re: Belt & Pully design - build question - 7 years ago

Quotehercek Does it compensate for wrong tower positions only or also for skewed towers (towers which are not equidistant to each other)? If it does the later too then that is great! Se could dismiss the calibration disadvantage of deltas as irrelevant. Deltas would need just more powerful/expensive hardware. Not a big deal. not sure about the equidistant but does do rotational and tilt 4-facto

Re: Belt & Pully design - build question - 7 years ago

Quotehercek Well, I typically use speed of 120 mm/s and accelerations 9000 mm/s², non-printing speed 250 mm/s. Why would one build delta if not for speed? Cartesians can print at low speed just fine and they are much easier to calibrate and do not need as powerful electronics. Well there are some other reasons to use a delta printer as well. E.g. when one wants to print very tall objects or jus
