I'll discuss these limits in future posts in this thread. I had a great learning experience with the V90, but I'd also found some limits in its design that I felt were affecting my productivity. Something keeps drawing me back to these pretty little machines, but I also see a lot of advice about not using them for wood, and their performance envelope was a little slow.ĭid I want another V90? Yes and no. Then I looked at the Sherline and Taig machines. I needed an additional machine, and it had to be cheaper. Secondly, I'd have to sell a LOT of toys before making a profit on my time and expense. Firstly, one machine can only make one cut at a time, no matter how good it is. I looked at Tormach with lustful eyes, I looked at Shopbot, but as much as I liked these machines I had two problems. I got more ambitious, designed a wider range of accessories, and quickly realised that one, small CNC machine wasn't going to keep up with my plans. My wife's friends started seeing the toys I was making, and began to ask if I'd make some for them as well.

After three iterations of hardware and software design I had something working to my satisfaction, and I started on my original plan of toy making.Īs often happens, you do something for yourself and others want it as well. My machine came, I set it up, and I spent the next few months writing firmware to drive it from a USB port. Even including shipping, the V90 kit cost me far less than a set of parts to build a similarly sized machine would have cost me locally. Also, living in Australia means that I don't have the wide range of cheap DIY products available in the USA. These factors meant I wasn't interested in building a machine from plans. My objective was to make things, not machines. I'm also not confident in my ability to do precise tool-quality work in wood.

While I do have a good range of woodworking tools, I had no metalworking capability. My original requirements were a machine that would help me build some toys for my children (the justification), be available as a complete kit from one supplier, have good quality instructions, and a strong support base. Woodworking is my hobby, computer software is my profession, and CNC offered the chance to combine both. I bought the V90 before John started making the Microcarve machines. This should be interesting, as the V90 was designed by the same person as the MV3 - John, otherwise known in these forums as Microcarve. During this thread I'll make a lot of comparisons between the V90 and the MV3. I bought an MV3 - a fixed gantry machine with MDF sides and table, an aluminium frame, and an oilite bearing/unsupported rod guide system.

I recently added myself to the growing list of customers for the Microcarve machines.
