0.9° Stepper - Worth it? - 5 years ago

I'm planning a Ultimaker clone, I have enough 1.8° degree steppers but I may buy 0.9° motors if they would produce an improvement in print quality. I can see a potential on the X and Y but what about the Z and extruder they seem less likely? Atb. Aamcle

Cross bracing 2020? - 5 years ago

The usual way to make a 2020 box/cube printer frame more rigid is to add panel sides often by bolting on Acrylic sheet but it should be possible to use some sort of diagonal bracing possibly with more 2020 or flat strip/plate. If you have tried to use braces now did you get on? Any links and pictures or even builds? Thanks All. Aamcle

I renewed 360 a month ago so it's not urgent but.. I don't want to get so locked in that I can be ransomed. Thanks.

Cad for printing...?? Moving On? - 5 years ago

I've been using Fusion 360, Autodesk have already upset me with a major change to the interface I'm new and was just getting use to the old desktop and now they are changing the licensing as well. I'm familiar with FreeCad, OpenScad (not for me...) and the names of a few others, I've put some time into Fusion and it seems I may loose out as Autodesk may look for too many $ from me or reduce t

Re: Enclosure Temperatures? - 5 years ago

Right then if I don't go over 50°C I can carry on with Petg but I may change to a design with more metal. Aamcle

Re: Enclosure Temperatures? - 5 years ago

Although it's unlikely that I'll print high temperature materials like PEEK or Polycarbonate I would like to be able to print carbon filled petg and to have the potential to print exotics. 70-80°C is getting relatively close to the glass transition temperature for Petg it's beginning to look as if I need to print in ABS. Oh Dear... Thanks aamcle

Enclosure Temperatures? - 5 years ago

I have started printing the plastic parts of my build but it's going to be an enclosed (side walls n top) printer or in an enclosure. As I happens I have started printing with Petg rather than PLA but I have no idea how hot it should be in an enclosure or an enclosed printer so I am unsure if that's the most appropriate material. What temperature range are you using in your enclosures? Thank

Re: How big can I go? - 5 years ago

I'm going to push a known build out a bit but "bite the bullet" and put sides on it which should give me the stiffness In looking for. It's a Ultimaker clone from Thingiverse, I'm interested in rather than a Core build because I believe motion system is better balanced but that is just based on a feeling and the idea that UM wouldn't use it if it didn't work. I contacted Igus today and I should

Re: How big can I go? - 5 years ago

Lame? Yes probably but then questions from the ignorant to expert often are. As for stacking 2020, well the query was specific to the design I linked in all. All I wanted to do was find out if I could make that printer bigger without any major changes to the extrusion sizes so I would not need to design a new set of parts. Never mind ....

Re: How big can I go? - 5 years ago

That would get me a build plate the size of a postage stamp! I'll rephrase the query, how big can I go using 2020 and 2040 extrusions for the cross members? Atb. Aamcle

How big can I go? - 5 years ago

How big can I go? I know this is vague sorry, I looking at a box design (2020 + 2040 extrusion) with Ultimaker kinematics. This one :- I would replace the top and bottom extrusions with 2040 for added rigidity, I'd probably add a second Z axis as well and use metal to replace plastic were I can. Obviously building it bigger isn't that much on a problem BUT I've no idea how big I can go with

Srek. It's a MK8 I should be able to manage ABS which is good. Aamcle.

Alternatives to Steel? - 5 years ago

Good Morning All. I think I've settled on a build that uses the Ultimaker motion system. The X and Y linear guides/smooth rods rotate and I'm wondering if there is a way of reducing their weight simply on the principal that less weight allows for more speed. Although the rods that support the hotend/extruder don't rotate reducing their weight would still be beneficial. What trusted and tried

Re: Link to Cartesian Plans? - 5 years ago

It's not the effort it focus, if I decide I want to make a widget learning how isn't a problem. If I simply sit at my PC and follow along with the Fusion videos the focus just isn't there. Aamcle

Re: Link to Cartesian Plans? - 5 years ago

I have, the basic frame would not be difficult there are lots of examples and other than ensuring its rigid and square it's not complex. Unfortunately my Fusion skills are poor so the various brackets and mounts would be difficult although at least I'd learn Fusion. I find Fusion difficult to learn except when I'm trying "to do something" simply following the Utube Videos shuts my brain down qu

Re: Link to Cartesian Plans? - 5 years ago

My Cartesian has a bed that moves down. So far the only well supported builds I have found are the Hypercube Evo and the Voron both are Core XY and both are very expensive, with the most expensive linear rails. Good job but pricy.. Aamcle

Link to Cartesian Plans? - 5 years ago

Link to Cartesian Plans? I've been looking around, I was considering rebuilding one of my CTC Duals with a 2020 frame and a new extruder but when I added up the costs I wasn't saving that much wrt a full build and I would have gained very little. I have a board, controller and stepper drivers so a good portion of the printer is to hand. I've looked around RepRap, OpenBuilds and Thingiverse but

Re: Filament choice for brackets! - 5 years ago

I have downloaded the STL's for the job and there are a range of parts, I thought I that I should print in ABS but really hoped for another option. I'll move the printer to the garage, put it in a temporary enclosure and see if my hot end will stand up to the temperature. Thanks All. Aamcle

Filament choice for brackets! - 5 years ago

After a brief but bruising encounter with the search engine I'm going to ask. I'm looking at a build or to be more accurate a rebuild one of my printers. I have the choice of printing the plastic components in PLA or PETg or even ABS which would be the better choice? I prefer to avoid the ABS stench if I can and I am currently limited to about 240°c as the hot end has a PTFE liner. I shoul
