General Mach Discussion / Screw Thread Pitch Control

« on: October 06, 2009, 07:00:54 AM »

I am currently retrofitting an Emco Compact 5 lathe to work with Mach3.

My plan is to monitor spindle speed but not control it dynamically from Mach3 and I've been wondering if that will be sufficient for thread cutting.

In other words does Mach3 dynamically control the velocity of the Z axis stepper motor to get the correct pitch regardless of spindle speed?

Thanks

Jim

LazyCam (Beta) / LazyCam 2 Pro Turn Error?

« on: May 08, 2007, 10:43:23 AM »

I have attached a couple of files. The dxf is from Autocad and the associated turn tap file generated by LazyCam 2.0x.

Mach 3 is hanging when trying to load the tap file.

LC is generating what looks like impossible k numbers in the gcode for Mach3 to process.

Apologies if this is already in hand for fixing or that my dxf is at fault.
