General Mach Discussion / Re: Z Axis Move - Triggers Soft Limits

« on: October 25, 2007, 01:56:41 PM »

Chip,
What I found out and verified yesterday from John  at EZ_router is that my machine does not have a limit switch for the Z axis.  When Mach starts it assumes that current position is Absolute Zero.     Solution is to jog the carriage up to the top of its travel, restart Mach.  Now I runs fine with Limits On......Whew!   Makes sense in hindsight.   ...Just never put it together.....The binding was the machine approaching what it thought to be outer limits.

Thanks for the input!

The .10" drop does not register on the DRO....definitely mechanical.... Is there any recomended Soft limits settings.....I should check with the guys at EZ-Router.....Thanks for your input...

General Mach Discussion / Z Axis Move - Triggers Soft Limits

« on: October 22, 2007, 11:58:09 AM »

Howdy!

I have been having a little trouble with consistant Z cut depths.  I can only run with the soft limits off.  Whenever I jog the Z with Soft Limits toggled on, it triggers the machine to stop. Before it reaches that threshold it/ the motor makes a weird digital type sound.  Sort of like R2D2.....but it runs nonstop with the softlimits off, but the cut depth isn't consistant......And after I set the Zero depth, send the router back to zeros, it will drop in the Z about .10"  When I start the cycle and the router/spindle starts....( Backlash?)  Any ideas of what to look for? 

I did have one (ok two) nose dives into the table......My old pc's power supply was causing reboots and othe rissues....Could there be damage to the coupling or adjustments needed to th estop nuts on the screw rod?

Thanks in Advance for any input!

Thanks for your replies......
I reloaded Mach to me back to default settings with the ez-router profile.  This only seems to happen on the Z axis travel.  Today it began making some "odd noises on any positve z jogs.  It only jogs with the softlimit switch disabled.  With the softlimit switch on, it trips it.  I have an email into the guys at ez-router, perhaps I need to look at the actual  Z-axis screw/coupling/motor.

Thanks again!  I'll post any further discoveries.

Howdy!
I am a newbie with a 30x48 Ez-Router.  Occasinally when I try to turn on my Soft Limit switch to zero the Z axis I get a message ...." Machine out of limits for SoftLimit Activation".   I tried regen of the code.   Do I need to home the machine at that point?  Also, should I be running the cut program with softlimits on?    When I do that it always stops and my settings/positions get out of whack.
