General Mach Discussion / jog screen does not dislpay

« on: November 14, 2018, 05:21:07 PM »

I've used mach 3 for several years and the jog screen has always worked as expected. I moved my milling machine (taig) and computer to a different shop. Now when I turn it on I can't get the jog screen to show when I press "Tab". On the right side of the screen I can use my mouse and it will grab a line and I can drag it over, thinking this would bring the jog screen back, but I  can't get the jog back at all. I have restarted but no help.
Any ideas what I can do?
Thanks

General Mach Discussion / losing steps

« on: December 15, 2010, 02:54:01 PM »

a few days ago I was taking off some material (aluminum) 8" x 2.5", DOC was .053 and stepover was at .2188.
I am using a carbide 7/16 em at 6500 rpm feed rate somewhere around 10. This is on a Taig cnc mill. I turned it on and it had made several passes and everything was fine. I left and came back 20 min later and now the machine had moved over 1.5" in Y The tool was where it should be acording to the Mach3 but it was not where I had set it. I uninstalled the mach software and reinstalled the latest version.  and now I have cut 2 of these pieces  with no problems. today I recut a pocket that needed to be deeper and everhthing worked as should. I changed to a ball mill, set my zero and started to cut and it was wrong. It had moved X .060. I rechecked zero and it was off .060. It did not throw a reset. I have had similar instances of this but was not for sure.
It looks to me like it is loosing steps somehow. I have not changed anything except in the motor tunning, the Step pulse. 3 months ago when I was having a reset probelm, the Step pulse was at 1 and it was recommended that I change to 9 and the reset problem went away. When I thought I was loosing steps I changed from 9 to 5 and didn't have any problems until just now.
I have no other programs running or installed on this computer. I have done all of the recommendations (found here) to get a computer ready for the Mach software. I am kind of lost at this point.
Any idea what might be going wrong or what I can do?
Thanks,
