General Mach Discussion / Edit X Position (newb, be gentle)
« on: January 12, 2018, 05:31:50 PM »
I can click the mouse in the 'Z' position display and key in a new Z position.  The 'X' position display doesn't allow me to edit.  I am sure that I am missing something simple.  Please help.

I have the canned 'Lathe' configuration working somewhat on a lathe retrofit.  I am currently running the demo software.  I am in the process of calibrating my counts per inch values for X and Z.   Using the MDI screen I am able to execute G0 commands and move X and Z fairly accurately (old lathe, significant backlash).

Can someone point me in the right direction?

thanks,
jh

Simon,

I recently purchased an Interact I Mk2 at an auction.  It has Heidenhain TNC 2500 controller.  I spent the better part of a day last week getting it to complete the initialization sequence. (I was pleased to get this far as I had no guarantee that it worked at all when I purchased it).  Like the machine that you have upgraded here, I am getting an intermittent X-Axis fault.  Sometimes the overload relay trips, sometimes I get a 'AXIS FAULT' error other times a 'GROSS POSITIONING ERROR'.  Seems to work ok as long as I keep the axis gain knob turned down.  I plan on spending a little time trying to run a program using the original hardware before I gut the whole thing and upgrade, so I would like to get this X-axis issue resolved.  I am hopeful that you can share the details regarding the 'brushes' on your x-axis motor that you discuss in the later posts. Did you replace them?  Where did you get replacements? 

As of right now I will probably follow very closely the steps you have so graciously recorded when I begin my upgrade.  Thank you for taking the time.  If you had to do this project over, would you do anything significantly different?

Also, how much HP do you think that you are getting out of the SSD spindle drive?  The spindle drive is working on my mill now.  It runs smooth at 3500rpm.  It is such an awful amount of electronic components that I don't know if I even want to try to figure out how to interface to it since I would probably just replace it as soon as I have a problem.

Thanks again for taking the time to blog your efforts.
