Sending a SMS text message to the EU from UK.It isn’t totally bug free but an upgrade is promised. If you hate your Mach3 GUI then have a look at what they are offering as a free download. While browsing YouTube I came across Physics Anonymous and enjoyed a rant by them about Mach4 and then the joy of seeing their version of a Mach3 GUI which I have to say was a breath of fresh air improvement. It is certainly not a patch on Tormach’s PathPilot. I tend to agree as I used to tolerate it on my small CNCEST milling machine. It seems that many user of Mach3 CNC control software love the concept but hate how it is presented as a user interface.
