Invalid axis combination

[jagg2499]

A coworker tried editing the mmd file and screwed it up so when i try loading int o fix it i get " Invalid axis combination" any tips on how to load this file to fix it or do i have to creat a new one from scratch

You should be able to fix it Jagg. Just open the machine def and then go from there to the control def. There must be a correct number of axis for your specified machine type and the axis direction must be set correctly. I had mine hosed up where it had 3 x axis and with help from here got it fixed.

it loaded a defualt machine defination because of the invalid axis combination so when i go to the machine definition mangaer to edit it i get an error saying the default one cannot be edited

HMMMMM that sucks. No backups? Always keep a safe copy of your MMD and post files stuck someplace safe.

jagg2499,

 

You could always try locking it to safe guard unwanted changes in the future. This would force you to edit a copy, or better yet allows you to edit and test the open machine def. in your Operations manager with out influencing the password protected disk copy.

all very good suggestions for next time but i would like to not have to start over from scratch this time

ON http://www.mastercam.com/Support/Multimedia/Default.aspx there is a multimedia page. Try downloading the MD/CD reference that is available.

You just need to fix the axis combination in the machine definition file (should take approx. 1 minute).

 

1) Either close X and reopen it in Design or select Design in the Machine Type dropdown and then select File New to clear the database.

 

2) Now select Machine Definition Manager... in the Machine Type dropdown. Load your .mmd (.lmd, .rmd, or .wmd) file.

 

3) Click the Edit Axis Combinations button at the top left corner of the Machine Def Manager dialog.

 

4) Expand all of the branches in the Components Used frame and look at the Axes and Components listed in the Axis Combinations frame above. You need a minimum of 3 linear axes (2 for lathe) a work holding component (Machine table, fixture chuck) and a tool holding component (spindle or turret). Find the missing axes or component and check it it the tree.

 

5) Green check out of the Axis Combos dialog and save the machine def file.

Thank you Paul that worked great you are my hero for the day!!

I went through this a week ago myself--another way to load the machine definition that you can't get to, is to select, under machine type, one of the generic machine definitions, then open the machine definition manager. From here you can open the defective definition using the file, open icon in the upper left hand corner of the window. For some reason when a defective machine definition tries to load, MCX loads a default definition that is located in the config folder. Browse to the cnc_machines folder to find the definition in question and then make the axis combinations adjustments necessary to make it valid again. Cheers.

I personally highly recommend doing any manipulation of machine definitions with the system in Design mode to avoid any confusion. Be sure to check out the multimedia section of mastercam.com as the videos and .pdf will help tremendously in understanding how MD/CD works.
