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! ;D

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... :D 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.
