pocket problem, error on arc

[DaveR]

On a Haas VMC, I get an alarm, illegal IJK move at the second to the lats line.

 

I'm using helix entry standard pocket seems like I've done this before with no problems. Anyone know what the issue is?

Hi Dave,

 

Does the Haas controler have provisions for posting with wear? I have seen this happen when posting with wear comp, try computer comp.

This was posted with computer comp, there is no G41 there.

 

The error occurs at the second to the last line.

Dave,

I just tried the snippet of code you posted above. My Haas does not give an alarm in the graphics simulation mode.

Holy cow why is that? This is a brand new machine I have, actin goofy. Nothing but IJK alarms last night over and over can not figure out what the problem is here. Tech is coming today to fix the program coolant nozzle I'll run it by him.

Dave,

I thought it might be a setting so I did a quick read but didn't find anything. Let us know what you find out.

 

Our coolant nozzle either got bent (machine ran at westech) or was not installed/manufactured correctly; positions 1-10 hit the side of the spindle down to the v-flange. The bent nozzle made it a real joy when the coolant came on unexpectedly.

I straightened it out good. No more coolant in my face and hair.

I notice there is no XY on the G2 line.

An arc move that starts and ends at the same XY can sometimes cause a problem.

 

modify control definition for "break arc at 180".

[Bryan Johnson]

The IJ values look to be incorrect, or the XY values are missing.

I ran your problem gcode through backplot in CimcoEdit 5.0 Its good code, a simple helix entry into a pocket.

Its been years since I ran a Hass, but I think they have some settings on the Parameter pages about how they run G02,G03 commands. There may be some tolerance settings as well

Here is some code from my Hass post. See if your machine will run it.

Its a Helixbore toolpath, cboring a Ø.200 hole
