General Mach Discussion / Re: Motion wont stop after keyboard jog

« on: January 31, 2011, 11:21:29 AM »

Forgot to mention, when I press the arrow key to jog in the desired direction the machine moves at the speed shown in the feed rate box instead of the usual feed rate shown in the slow jog box.

I have also rebooted numerous times and tryed a diff keyboard, checked all connectors .

General Mach Discussion / Motion wont stop after keyboard jog

« on: January 31, 2011, 11:16:42 AM »

I have had a strang issue creap up today that I hope is just a case of me accidently changing a setting.

I havent made any changes to my system in well over a year. This morning I was turning and threading parts on the lathe. once the part is done I place a new part in the chuck and use the arrow keys on the keyboard to slowly jog over and touch the end of the part then press the Z zero button on screen and then cycle start to begin machining the part.

I ran about 15 parts this morning and then out of the blue the machine started continuing to move after the arrow key on the keyboard is released. At this point none of the keyboard inputs are recognized and all my external inputs , cycle start estop and pause , do not work.  Once I click the Stop button on screen the machine stops moving and the external inputs work again . All the other keyboard comands work fine and dont cause this issue, just the slow jog. The rapid jog (hold shift and press arrow key) works fine and doesnt cause this issue.

Since things have worked fine until this point  I would imagine I have changed something somehow this morning while pressing the jog (arrow) keys on the keyboard.

Any thoughts or help greatly appreciated.

General Mach Discussion / Re: can mach be set to remember which tool is loaded on shut down?

« on: October 14, 2009, 11:08:58 PM »

still wishing mach would load the offset for the tool that was in que when the machine was shut down , broke a very expensive 12" long carbide internal threading tool today after a reboot today.  I cant think of any CNC machine built in the last 30 years that doesnt rember which tool was loaded at shut down and load the proper off set when restarted. Wouldnt this be a simple and useful issue to correct?

so how do I get over this issue? do i need to reinstal mach completley or just one of the macros? If so where and how.
Thanks

I also am still curious why mach cant load the offsets for the last tool that was used like every other cnc machine made in the last 40 years ?  I just exploded a $300 internal threadig tool holder after a reboot , second time in the past 8 month due to having to reboot after a script error when threading .

Just seems to me it would be simple for the software to remember which tool is in position when shut down and simply load the proper offset, am I missing some simple setting?

General Mach Discussion / script error 1076.ins ? another threading problem

« on: October 14, 2009, 08:14:43 PM »

I cut about 30 sets of internal threads  no problem today , pushed the cycle start button as I have 60+ time eariler in the day , spindle and coolant turn on as they should, tool moves to start position , g76 line is high lighted in code and nothing happens.  Line at the lower left of the mach turn window says script error 1076.ins and then a few more charcters than will fit in the display.

What has happened and how do I get back up and running?  Tryed rebooting computer no change . I have no idea what happened, no change in program , no power surge etc

I havent been having any problem the past few months with either of mine, one with a 2 hp spindle motor and the other with a 30hp . The 30 hp machine uses smooth stepper and the 2hp does not. Both use VFD and a single pulse optical setup  . I have cut somewhere over 2k threads on each machine, most 1"x 20 tpi with no problems

I didnt see the mode active info on the lathe screen.

I did put g95 in the string at the top of my code and it seems to be running properly again. Thanks Hood

General Mach Discussion / g76 problem with lathe

« on: September 08, 2009, 05:52:06 PM »

I have experienced a new problem today .  I am using the same g76 file I have used hundreds of times to thread on the lathe.

This machine has not been powered up in about a week . When my program runs the correct tool loads , moves to the correct position, spindle starts but the feed rate on the z axis is way off.  Usualy the feed rate is fairly high and sncs with the spindle speed and all is well.   Today the feed rate is just what ever the pitch value in the g76 line is.  In this case the thread is 20tpi so the pitch is .05  , the feed rate window reads .05 and the tool moves in the z axis at .05 IPM ,  change the p value to .1 , machine moves .1 IPM etc.


What has changed, why and how do I get the machine to thread again?  Is there a macro that needs to reloaded?
