Julian That will do me nicely. A good lesson, I think I am getting there, I will try something similar like a cube with less of those triangles to compute. Many thanks John

I managed to get the STL into a step and it was only 550MB, so I started looking at the design and there were holes all over the place, which means the mesh didn't. The link to the vase at cults

Julian's not working on an stl conversion, Julian's taking his first steps in working with meshes and it's very frustrating! Won't be venturing back into that work space any time soon. The model will

Julian Armin. Well I managed to create a STEP file from Armin?s STL Using Freecad, toolbars part, produce a mesh, produce a solid. STEP size 706 mb. WOW Brought into my Mastercam, to convert this

Jerry, Nice explanation. With rotary incremental encoders, you can usually buy one with what is called an "index pulse". This is a pulse that occurs once during each revolution, and is output on a

I love the kindling splitter! -- Regards, Charlie New Jersey, USA *NOTE: No trees were injured in the sending of this message,* *but a large number of electrons were terribly inconvenienced.*

Hi, John, Happy to help. The encoder generates the two rising and falling channels regardless of whether you evaluate them as 600, 1200 or 2400 PPR. The spec then applies to the 600 PPR. Each channel

Armin. Magic thanks. I can scale up to 200% but 150% seems good. Julian is also working on a STL conversion. So I will have a choice. I will be able to print "hopefully" a vase for my wife, B4

Yes please. My 3D will accept up to 255 mm x x 255 mm Y x 260 mm Z Cheers John

I've been playing too! Is this acceptable ... I've had to cut the top off a little.? The original stl is around 1000mm high.? If I scale it to 100mm I think the wall thickness will be around 2mm.?

John, if its just for priniting I found a similar vase on Cults3D.com that can be sliced in PrusaSlicer. I'm not sure if the link https://cults3d.com/en/3d-model/home/vasedoubletwist4mm is allowed

Thanks Julian for your understanding, this conversion (reverse engineering) is like making glass, once it's melted, a devil's job to get back to the raw materials. I think the new Prusa slicer

John, I tried doing the same exercise a little while ago and failed miserably.? Free version of Fusion restricts one operation in the process which has to be done manually triangle by triangle.? My

Can anybody help. I have downloaded a STL file for slicing. Such a nice shape and style. I need to convert to a STEP file so I can draft in a hole. I have tried Free cad and Solid edge, I get so far

Charlie Thanks for the explanation on the limits of the encoder. ?Perhaps you can help me further understand the capabilities of my encoder. The relevant specs are, 600 ppr, mechanical limit 5000 rpm

Thanks Charlie , I actually got a lot of that , though my math has been way underutilized for quit some time . Your statement about the import encoders or even other parts like that can all too often

Hello, fellow machinists, I worked in the design input and implementation of rotary shaft encoders manufactured by my employer on and off for over 30 years. I haven't noticed anyone mentioning the

Jerry was that meant for me & my Tach ? or aimed at Ralph's encoder ? thanks animal

Thanks John . animal

Fwiw, it's fairly easy to set up Linuxcnc which lsupports encoders. I'm running encoders with 1um and 5um resolution using mesa fpga cards. My lathe encoder worked at threading rpm (120rpm) using the
