I went to cut my first operation and ..... nothing..
« on: August 31, 2013, 07:03:40 PM »
Well it wasnt exactly nothing. All day today for about 12 hours I was setting up read preparing getting everything in tram. Broke my starett dial indicator. (Turn the spindle on and forgot it was in there)
I ran the XY to there farthest negatives and Z to the farthest positive. Hit reference all.  loaded g code , zero out XYZ regen tool path.
The cnc rose to the top of z then brought xy to the farthest limits.
Im all excited  ...
It goes to the corner I specified in cam right as its bout to take its first cut the motors start pulsing is the only way I can describe it  . they werent event moving .001
System jogs fine I set backlash up today fine . If I tell it move .030 it moves that distance.
My head hurts I can really use some help.....

I went into my cam changed the feed rate , depth of cut shortened the gcode same thing.
Heres a vid also . Ill upload the gcode but its the on I asked you to look at .  
I turned the spindle off for the vid because I knew it wouldnt cut anything .

You have a G21 (metric units) at the start of the program so the longest axis move hence size of road runner will be 0.100" square. That could be the problem. Jim

What's my xml ? What's that do .
Jim I designed the part in metric and inches . Every time I load mach in settings it changes my its from inches to metric. So how can I make sure it stays as a standard . In cam ?

A few members have had a similar problem, I don't use any cam software so can't help I'm afraid but suspect you can define the base unit of measurement.  I did have a different problem when I first set up Mach I inadvertently managed to switch the metric/imperial units when doing the basic set up so my machine was doing things in metric although I had written them in Imperial, I had to reload the Mach software and redo the set up. If you do that remember to save your licence file some where safe first! You program looks as if its in imperial, have you gone into edit file and changed the G21 to G20 on the set parameters line, it then should cut 2.5" square. Jim

Thanks for the help Jim ,
License won't be a problem since I'm still in demo mode and trail mode on all the soft ware I use.
I'm not pre paired to pay for any soft ware if its not compadible with me my brain  or my stuff.

As Jim has said it is G21 in code but it looks like dimensions are meant to be metric and thus the axis are hardly moving.
I was wanting to see your xml to see if your setup units were correct and for inch but if you try as Jim suggested and change the G21 to a G20 and see what happens, if not you can attach your xml by looking for the profile name when Mach is opened. You then go to the mach folder and look for a file of that name with a .xml file extension. Copy that to your desktop then rename to mrich0908.xml then use the additional options on the reply page to attach the renamed file.
