Are the motors and/or machine new? If yes then it should be the supplier's responsibility. Which wizard did you use, in in-built Mac one? What is the steps/rev of the motors/encoders? I very much doubt if the drivers would work without the encoders. Are they servos or closed loop steppers?

Mach4 General Discussion / Re: Mach4 Lathe: Cutting a 7/24 taper for BT30

« on: August 01, 2023, 03:29:40 PM »

Below is the Gcode to turn a BT30 taper using Mach3. I wrote this some time back, actually using a spreadsheet to do the calcs and generate the code. I attach the spreadsheet as well. It seemed to work as the taper fitted the socket on my Novamill pretty well.

Mach4 General Discussion / Re: 3D Edge Finder procedure query

« on: July 20, 2023, 06:26:56 AM »

The bottom photo shows a low-cost version of the ubiquitous "Renishaw" touch trigger probe. They have reasonable over-travel capability, 5mm or so I think? They have to have this because apart from operator error etc the probing procedure can't stop instantaneously to there is bound to be some over-travel. It isn't essential to lock the spindle as long as the probe point is properly centred using the adjuster screws. Unless you are working to very close limits standard collets should be OK. I believe you can apply a calibration routine that will measure and compensate for slight runout - I think a bit of code I downloaded as a Mach3 macro has that.

You're correct that the 3D probe isn't useful for Z setting unless you can set your cutters with a precise "stick out" which you store for each tool in the tool table. I did have a go at that once by adding a back-stop to a collet chuck, but it was too fiddly and anyway rather suffered when I had a tool crash! Easier to set the height for each tool when you fit it in the chuck.
