General Mach Discussion / Re: FEED ADJUST MACH 3 LATHE

What do you mean by the top speed display?  Isn't that the actual measured speed?  If you toggle the button I think it should show the actual speed or zero (thinking machine is stopped).

Spindle button 3rd to the right of Estop.  You may not need it if using Mach3 to control speed, but when I started doing threading I didn't realise that until you "press" this button Mach3 doesn't think the spindle has started.  Worth a try?

Silly question, but have you clicked the S button so M3 knows the spindle is running?

AFAIK there is a parallel port plugin for Mach4.

Answering (I think) my own question, running in simulation mode suggests that this does indeed work.

General Mach Discussion / Cutting an internal thread
« on: June 13, 2018, 04:26:30 PM »
Well I've reached the stage where I need to cut an internal thread on the CNC lathe.  I use the Simple Threading wizard for OD threads but there's no obvious way to tell it I want an internal one.  On the other hand if I make X End larger than X Start in the wizard it generates code and doesn't raise an error - is that the way to use it for ID threads please?

Mach4 General Discussion / Re: Mach 4 Spindle Speed Control
« on: June 12, 2018, 02:08:08 AM »
Have you got some smoothing in the PWM output that feeds the speed control input on the VFD?  Also the VFD speed control voltage range is usually 0 - 10V whereas the PWM output is more likely pulsing between 0 and 5 V so it needs some gain.

General Mach Discussion / Re: SetToolX() documentation

Dave, just to repeat my thanks, as I've just got my tool setting macro working properly thanks to your input.

I can mount a tool, give it a number in a DRO, position it in the shoulder angle of my test bar of a known diameter, click "Measure Tool", and a minute or so later the offsets are measured and stored in the appropriate line of the Tool Table.  For me, a result!

Dave, good input at exactly the right time as I'm rewriting my tool setting macro and you have just saved me hours - many thanks!  To make sure I understand the operative command is:

SetToolParam(<tool number>,<param type from your list>,<parameter value>)

Correct?
