Also there is very little room to mount them and in comparison to the size of the machine they are huge.īasically they would look terrible and I had my doubts as to how accurate they would be. In fact they would probably be an extra hassle if they malfunctioned and also they would need to be kept clear of chips and dirt. When I ordered my Taig cnc desktop mill I added some limit switches to my order thinking I would need to use them as homing switches.Īfter setting up my machine and getting used to how it operates with Mach 3 software I quickly realised they were not necessary. The difference with these “industrial” machines is that the software is designed to use them and they are essential for it to operate correctly. Simply put, if your machine did not get delivered with them it does not need them to operate.Įvery machine I have run in my career as a machinist has had limit switches built into it. I am sure that somewhere on the internet at any given time there will be several people having a discussion on the need for limit switches on a hobby cnc machine. This article will answer all these questions and more… well maybe not more, but I will explain what I do and why I don’t use them on my taig desktop cnc mill. Do you need them? How to set them up? Can you run a machine without them? When working with home based cnc machines such as routers and desktop mills I often see questions on internet forums about homing switches. On a small hobby mill, limit switches can also be used for homing a machine at its ‘machine reference point’. Thanks again for your time and cooperation.Limit switches are used to prevent a machine from running into the end of its travel and getting damaged.

However, you should be concerned about saving toolpath output files in the format compatible with your CNC machine only. I've not tested importing each of the many different types of toolpath output file formats into ArtRead, so I cannot reliably say which of them are incompatible. Is there any other format that supports machining but should not convert as model ?
