I used Mach3 for several years on my Tormach PCNC770. When Tormach released PathPilot (which is mostly LinuxCNC) 3 years ago I converted. There is absolutely no comparison between the two types of control software. LinuxCNC hasn’t crashed or randomly done funny things over the last 3 years, the user interface is very attractive with clean elements instead of the gaudy default colours of Mach3, touch screen operation is a delight, the tool table works reliably, soft limits work, I can transfer files to my machine over Ethernet and even surf the net while running a job, the GCode dialect supports named variables and conditional execution which is great for hand written code but most importantly bugs are fixed with updated releases several times a year rather than being ignored. In summary, I would even consider going back to Mach3.
