Mach3 under Vista / Pause for tool change and Z reset

« on: November 06, 2018, 09:15:24 AM »

Iapologize if this has been answered before but I've only found info that partially answers my query:

I'd like to do the following: create 2 or more toolpaths, join them manually and insert between each toolpath code that would allow me to:
1-pause the machine and stop the spindle
2-Change tool
3-press button assigned to Autotool
4-Continue program clicking Cycle Start restarting spindle

Any ideas how to do that?

Thanks a lot!

Mach3 under Vista / Help with STEPS PER UNIT CALCULATOR

« on: October 04, 2018, 06:08:52 AM »

Hi

I'm new to this forum and I'm trying to use the STEPS PER UNIT CALCULATOR. I'm quite new to CNCing and I'm spanish so excuse my ignorance and eventual language barrier.

I have a chinese 3 axis 40x30 machine with a JK02-M5 Breakout board, 2M542 Stepper Motors, and a Dell Optiplex 745 dedicated computer.
The Balls screws on my machine are "1204"
I work in metric units.

My first question is: in the section "leadscrew" of the STEPS PER UNIT CALCULATOR would "pitch" be 12 or 04? Same for "lead".
My 2nd question is: do I have to fill the lower section of the calculator and if so, how? (feed, Stepper RPM, Pulse/sec, Distance vs Steps)

Thanks a lot for your help

Cheers
Sono
