General Mach Discussion / Re: Controlling THC below 5%

« on: May 10, 2016, 10:59:59 AM »

Rob,

The "height software" I found and edited to suit my  needs.  I have a very fast and robust Z drive. I like it that way.  The motor is running on 60V, a couple of amps with a 1605 ball screw.

The "height software" detects the metal, moves to transfer height, turn on torch, pierces , them move to cut height.  This works fine.  If I slow down Z full speed,  it increases my run time a lot.  On short cuts (artwork), I spend more time in that software than running the cutting Gcode.

Rob,
 I was not wanting to change the motor tuning (speed) setting.  My "height detection" software slows down to a crawl if I do it that way.  It will hold my 1% setting set in the XML file if I never try to change it on-screen. 

If I understand your reply... the fundamental Mach code has this valve screened at 5% or higher.   Too bad... it is what it is, I guess.

General Mach Discussion / THC Speed setting below 5%

I need to set the "THC Speed" on the Plasma screen set to 0.5%.  If I change in in the Plasma XML, it will be what I entered when Mach3 first opens.  But if I try to change it on screen, it revert to a min speed of 5 or greater.  Somewhere the screen set is prevented from going lower than 5%.
