« on: January 27, 2015, 03:24:25 PM »

Years ago when i set my machine up i thought it was pretty accurate, but it appears my z access is off by .0181"  This isnt too big of a difference unless i am using 1/8inch material it is off.  I cant remember how I set up that screw / motor setting in software.  Can anyone assist?

General Mach Discussion / Bits not cutting exact width

« on: January 01, 2015, 01:52:21 PM »

Question.

When I set up a project with pieces that will fit together, the bit I specify in the cut, doesn't cut exactly.  Example.  If i have a project, lets call it a piece together dinosaur using 1/8 exact plywood, using a .0625 exact end mill, cutting on the outside of the line, it is cutting smaller the 1/8 inch.  this happens with all sizes.  1/4,1/2 etc...  when I measure the with of the notch in my program, it is exactly the width it should be.  When cut, it is always smaller.

Help?

Thanks!!

Happy New Year!!

General Mach Discussion / Relay Board

« on: March 29, 2013, 08:49:20 AM »

I got a new controller, the gecko g540.  I also bought a relay board from probotix. I have ticking with this relay board for two weeks.  I cannot get it to work.  So, with that said, i worked last night with probotix tech support (awesome guys) and gecko tech support, come to find out that the relay board from probotix's (and everyone elses i can find) is incompatible with the gecko g540.  The Gecko g540 switches to ground when the output is turned on.  Probotix and other relay boards i found swith to positive voltages (probotix's relay board looks for +5v to trip the relay).

So with that said, without having to build a second set of relays that switchs the voltage around so the probotix relay board will work, (this is what Probotix recommended)  is there any relay boards out there that will work with the g540 without modification???

General Mach Discussion / Strange Question

« on: February 05, 2013, 10:25:19 AM »

my y axis has two motors.  sometimes when cutting hard material one of the motors will get "stucK'.  Stuck is the wrong word, the motor isnt holding the strong enough.  Meaning, i sometimes move the motor manually if i apply enough pressure (not go i know). can i increase the pulses or holding power to the motors?

Maybe im wording this wrong.

Hi Everyone.  Need a little help on this one.  Is there a way to after a job has finished, for the machine to move the router to a pre-designated part on the table, lift the z up to the top and perform an emergency stop (to stop the router.  I have the router wired into the the emergecny stop pins) all by itself?
