Over the years I have bought Microsoft Windows and other products. I kept most of the disks and keys but none of it will install. This makes it more tempting to just buy another computer (which will have another Windows licence with it).
It’s bad because if your PC goes down you are stuck until you buy something to get it going or just install linux (ubuntu).
In the older days PCs that came with windows had disks to install for the event of hard disk loss. These days, you have to make them yourself. I used to collect all them but it’s hard to keep track of which disks go with which computer.
I currently have about 18 computers (servers, desktops and such). Most came with Windows installed but no disks to reinstall.
I have a computer down and wanted to install Windows so I could run some software that requires Windows.
I went through my disks and there is nothing there that will install. I have an XP Professional that I purchased but it’s not working for some reason. I called Microsoft but they want 70.00 dollars to talk about it.
I’ve been borrowing my friend Guy’s (from the Ottawa Robotics group) a bit and I have other offers from guys like Micheal in Smiths Falls.
I initially thought of building one thinking it could save money. Micheal (also of Ottawa Robotics) was helpful in finding some parts online and with local suppliers. Guy has been successful at building one of his own.
I decided after shopping around that it might be a good idea to get a small one to start with. At least if I want to make one I can use the CNC mill to help. 🙂
Working area: 580mmX400mmX60mm
Max thickness of the material: 790mm (distance between Z axis and bottom of work station)
Work station: 750*480mm
6061 aluminum alloy + 6063 Industrial aluminum
Slide unit: X axis 20mm Chrome circular orbit, Y axis 16mm supporting rail, Z axis 13mm Chrome circular orbit
Stepper motor: New 2.8A two-phase 57 stepper motor
Drive unit: 1605 ball bearing linear + cased muff coupling
Spindle motor: C57 300W DC motor, used, from USA, super-low noise, speed 3000-9000, ER11 3.175 collet
Spindle accuracy: radial runout 0.03mm
Engraving accuracy: better than 0.04mm, has been tested
Resetting accuracy: better than 0.03mm
Idle load speed: 0-5000mm/min
Engraving speed: 0-2500mm/min
Control box (electrical): 3977 3-axis control box with the power supply + spindle speed regulator
It comes with a spindle and spindle controller. I had the supplier strip all electrical so I will use my own. This saves on shipping and I was able to get it cheaper.
I realize that’s a pretty low powered spindle but I think it’s a great starting point for a hobby shmuck like me. 🙂
I may use my own steppers and controllers. I have already acquired all the parts and am starting assembly now. If I do that, I will take the electrical off this and use it with my Mantis project.
