![]() To be honest - I'm not quite happy with this yet so I will, most likely revisit that design and do a new version during the month it takes for the first electronics components to reach me.Īs far as the frame material goes. So now I am so far that I have figured stuff more or less out in autocad and done some assembly thinking in autodesk inventor. These should arrive in about a month or so (free shipping from china, eh) ![]() I have currently ordered a DB25 breakout board, one of these drivers and one cheap stepper motor to test the concept. After some back and forth I decided to use DRV8825 based stepper drivers that are initially designed for arduiono but as far as I can see they should be also driveable from the parallel port of a PC with the linuxcnc without major issues. Although I must add that I do like a Core XY concept a lot - it just was not as conservative with additional space and I'm not sure of rigidity of it for my porposes as I'm planning to use only 6mm thick material for chassis.Īnd then some electronics for the stepper motors and hooking up the PC. I did consider belts but regular metric leadscrew seems to be a bit cheaper option for me everything considered including cheapest possible deltrin anti backlash leadnuts from ebay. Currently thinking of just using 28 mm Inner diamater pipe clambers and a small opening in the underlying plate to fix them in place.ġ0 mm regular metric leadscrews. ![]() expensive and will have to jury rig something together for holding them. I am going to get only the bearings without the brackets to hold them as these are sort of. At first I debated between 8 mm and 12 mm but 12 mm calibrated rod is not available in here and all things considered the 16mm was the next option. That means that currently my plan is roughly something on the lines of:ġ6mm calibrated linear rods (available from one of the local shops at reasonable price) and 16 mm linear bearings. I expect to get somewhere within a year or so so it is not going to be a fast project by any means.įor a start I did a spreadsheet with several options for comparing them:Īnd then, after looking around for a bit more did a smaller table as the initial one had grown over my head I thought about it for a week and then decided to put the PC case project on hold for a little while and delicate what free time I have to making a hobby CNC machine for myself. The price quote ballpark was about the same as I had estimated very roughly the cost of cheaper end electronic components and cheapest seemingly reasonable enough bearings, leadscrews or belts, etc. I had been bouncing about the idea at that point for few weeks, doing the reading up on the stuff on what little free time I had in my life after little daughter, wife and work had taken their toll. Out of that about 30 EUR is the material cost.īut by that time I was already thinking something on the lines of "if I would only have the cnc machine myself in my basement". With all the taxes added in about 225 EUR for cutting less than one square meter of 2mm thick aluminium (about 28 meters of cut line) and twelve 90 degree bends. The price was fair, I would say, but way above what I expected. well then I got a price quote from one of the local metal shops with 4 kW laser after poking at companies not really interested in doing it for me for half a month. For a start there was an idea to do a custom PC chassis out of 2 mm aluminium: I got it all figured out including assembly in autocad inventor nd exported flat patterns for laser cutting.Īnd then. everything has some kind of start as does this project. Overall, 2D sofa CAD blocks are a useful tool for creating detailed and professional-looking designs of sofas in a 2D format.So. They can also be customized to match specific design needs or preferences. This allows for faster and more efficient design work, as well as greater accuracy and consistency across different projects.ĢD sofa CAD blocks come in a variety of shapes, sizes, and styles to fit different design requirements. They can simply select the appropriate block from a library and insert it into their floor plan or design. These blocks are typically included in a library of furniture CAD blocks that can be inserted into a design project as needed.īy using 2D sofa CAD blocks, designers can save time and effort in creating their designs, as they do not have to draw each sofa individually. ![]() 2D sofa CAD blocks are pre-drawn 2D representations of sofas that are used by architects, designers, and drafters to create detailed and accurate floor plans and designs for various spaces, such as living rooms, waiting areas, and lobbies.
