    Buying a metal lathe, need help

    in Coffee corner

    Posted

    I recently bought a used Unimat 3 out of the 1980's - its quite small, but my plan is also to do some work on hot ends etc.

    What I learned: for turning a stainless steel part, this small thing is too weak to get the right pressure of the tool to cut. the Proxxon 400 is a bit better, but the Bernardo is ok from it´s size/weight.

    I only know similar cheapo lathes from my purchse journey which looks a bit "low-quality" to me so finally I decided to go smaller but reliable.

    Also a milling post is nice and for milling hotend parts enougt.

    I would recommend a used EMCO Compact 5 - take a look at http://www.nielsmachines.com - there are sometimes good machines available...

    Integrating Printer-json-definition-files into Cura "add new printer"

    in UltiMaker Cura

    Posted · Edited by Guest

    I also have a custom json which is displayed in the add printer as it should.

    First please check the following:

    - have you defined a different/unique id?

    - have you defined a different/unique name?

    - have you defined the category? In my version I defined "my printers", so all variants are displayed in this category in the add printer dialog.

    Here is my working example for my UMO (which is originally a dual head machine) - the first lines of it...

     

    {   "id": "ultimaker_original_single_right_CE",   "version": 2,   "name": "UMO SiRight Extrusion CE",   "inherits": "ultimaker",   "metadata": {       "visible": true,       "author": "Ultimaker",       "manufacturer": "Ultimaker",       "category": "my printers",       "weight": 4,       "file_formats": "text/x-gcode",       "icon": "icon_ultimaker.png",       "platform": "ultimaker_platform.stl",       "has_materials": true,       "machine_extruder_trains":       {           "0": "ultimaker_original_CE_dual_1st"       },

     

    Further you can use a json validator to check, if the file isn´t corrupt - if it is, it is also not displayed...

    Try this one: http://jsonlint.com/

    Hope this helps :-)

    UMO Dual Extrusion with Cura 2.3

    in UltiMaker Cura

    Posted · Edited by Guest

    Yessss, it was a bit tricky to get the json running as I have a heavy modified UMO dual, but finally it works as expected.

    Only hurdle currently: if you print a part where you just need the first nozzle, the second will be heated/primed too and then cooled down - result: oozing.

    Workaround: two printers - one with single, one with dual setup...

    but this is already reported and I hope the SW team (@Ghostkeeper) get´s a fix soon...

    Support Mesh & Anti Overhang Mesh

    in UltiMaker Cura

    Posted · Edited by Guest

    sorry, maybe I'm too stupid to understand it, but could you please once again explain the aim of the meshes (support mesh, infill mesh) and how they are intended to work...

    tried around with two models - one the print part, one the support part, but was not able to understand the process... maybe with some pictures would help too...

    Cura 2.4 Beta - Cubic Subdivision not showing up in layer view

    in UltiMaker Cura

    Posted · Edited by Guest

    You are lucky guys - my Cura 2.4 quits with error after trying to slice something...

    With a standard UMO it is fne, but as soon as I use the pre-defined dual UMO and select the second nozzle for support, it stops with the note "Cura Engine stops working"... :-(

    Edit:

    found the reason for crashing in my case. If a setting is empty (here it was the retraction speed at the second nozzle), it crahes, when a value is filled, then it works as expected...

    Using the Ultimaker3 CORE on an Ultimaker2

    in Third party products & modifications

    Indeed that part is what makes the core fixed. The chamfer seems to be a 60 degrees. Don't make it 45 or will loose stability. You have the photos I sent of that part?

     

    yep, still have them ,thanks. what would your guess be as to what material the plate is?

     

    Not sure. Fells heavy for aluminum and since the printhead small boards is touching it I would suppose is some hardened steel (specifically for the color and how hard is to scratch it).

     

    hardened steel or stainless steel seems clear as the counterpart of the core is also made of steel - any other combination would wear too easy...

    Ultimaker 2 Dual Extruder einstellen.

    Nö, dort habe ich eine kleine Wulst konstruiert die oberhalb vom Sechskant ist.

    Damit die Haube nicht runter fallen kann. Eine art Clip/Sicherung.

     

    Manno... geile Idee... hoffe, du verscherbelst die Dinger auch extra :-)

    Was für Silion hast du da genommen - irgendwie hab ich noch nicht das Richtige für solche Abformanwendungen gefunden...

    Cura 2.3.1 Filamentkosten ausgegraut?

    in Deutsch

    Posted

    die felder waren in allen versionen von cura 2, in denen sie bis dato angezeigt wurden ausgegraut - sozusagen vorbereitet für die zukünftigen entwicklungen. lt. dem github eintrag wird das aber noch ein paar versionen dauern, bis die Funktionalitäten verfügbar sein werden.

    PIB polybenzimidazole Isolator Coupler

    Aaahhh.... great idea... With the use of PBI yo on the same track than me, but I'd like to apply the PBI parts to my beloved UMO :-)

    My first thought was just to replace the PEEK and PTFE parts with PBI, but I also think it is not worth the invest...

    Do you think that these parts will also work with PEEK or PTFE?

    With PBI I was pretty sure about that, but I can't tell with PEEK or PTFE...

    Ok, maybe I was'nt so precise with my explaination :-)

    I´l put it into German...

    Servus,

    der Ultimaker Original hat jene Teile, die das Hot End darstellen aus PEEK bzw. PTFE (sieh dir mal das Dasign an), der Ultimaker 2 hingegen hat ein anderes HotEnd design.

    Ich habe einen Ultimaker Original, daher war mein Ansatz, die bestehenden Komponenten, welche aus PEEK und PTFE gefertigt sind, einfach gegen idente Teile aus PBI gefertigt zu ersetzen - leider zu hohe Kosten, daher verworfen...

    Sooo, back to English :-)

    For all non-German speaking guys in short, briefly desribed the design differences between UMO and UM2 hotends...
