Howdy all.  VERY happy demo user, got my rig built and set up so far so that it will "REF ALL" and home itself using the limit switches.  Woohoo! 

One thing I've noticed though is that each axis will count twice the distance moved on the DRO.  One inch of movement reads as +2.000 on the DRO.  I tried playing with the motor tuning settings but it only moved slower - I'm sure it's something simple enough that I'll smack my own forehead when someone explains it to me... 

My first foray into CNC is getting more fun by the minute!  Can't wait to see some chips fly! 

Try doubling the steps per inch setting in the motor tuning.

(;-) TP

Ah - that's it, in addition to doubling the ipm and acceleration settings!

Now all I need to do is try to make some chips!

I love it when a new chip slinger is born.(;-) TP

My controller has multiple settings for whole/half/quarter/eighth steps, and I either did the math wrong or the documentation is incorrect.  Given that I smoked the board once because the documentation was wrong about which contacts were 5V vs. 12/24V, I'm voting for the documentation being wrong...   Thankfully the vendor sent me another, along with correcting their documentation and sending out a new revision!

Now I just need something simple to make and then I need to spring for the full version of Mach3 too, so I can get something real done with it!  I have tons of CAD/CAM/CNC software downloaded and I'm anxious to try it out, but some of the programs just make Mach3 blow up immediately with errors like "can't do a g1 with feedrate of 0" errors and the like...  Learn, learn, learn.
