Thanks Neale, interesting thought and yes I have z tuned the same as y, I think at 5000mm/min velocity and 500mm/s².

To do the pro tuning it looks like you need a serial port and a special cable which is a pain!

I have pretty well copied over my current Mach3 settings to version 022 on an old laptop. Bit laborious but I didn’t want to just use the xml as this was advised against in the Mach support forum. It seems CS Labs recommend version 022 as the most stable, so let’s see!

Also, I’ve just bored out a 20mm cable gland so I can get an rj45 through it - I want to get rid of the two-Ethernet-cables-with-a-connector setup I have at the moment as that can’t be helping (!) and run the Ethernet cable further away from the VFD. It goes out the top of the cabinet and over the top at the moment...
