General Mach Discussion / table display and what i cut is backwards

« on: August 06, 2013, 09:22:24 PM »

I used the trial version of cut 2d.  I cut the Rocket name plate out but it was reversed on the wood.  Also the Table display is reversed.  This was my first cut and even tho it looks great it is still backwards.  can anyone help me.  also i have set up my limits and homing and all that works fine.  when i reference everything goes to the home position.  I did however do a dry rum before i cat with the z axis up high and noticed the z axis was running backwards so i just reversed it in motor outputs.  maybe thats not right but i have been on this project for over a year and wanted to see something work..

General Mach Discussion / How can i control spindle for test

« on: July 27, 2013, 05:34:08 PM »

Hello Everyone. My name is George Merzbacher
I built my own cnc router table and am currently trying to get the mach 3 to talk to my VFD for my spindle.  I have no experince with CNC but just one day i was searching the web and came across a build it yourself cnc.  started doing research and after a time i started building.  I think i have the spindle configured corectly but cant figure out how to try it out to be able to check my voltage at my breakout board. I get 0 volts and when i toggle in Diagnostics I get 10.20 Volts but how can i check it like at half RPM to see if im getting 5 volts?
