Fixture Offsets

[NeilMGW]

Hi, I've been using NX8 for a couple of months and whilst I'm really enjoying the level of explicit control I'm struggling with a few things I consider to be fairly basic. Fixture offsets is one of them. I've tried insert -> geometry -> MCS and allocated a fixture number but it's not showing up in the post processor output so I guess I'm missing something. Also Fadal's use E 1-99 fixture offsets, any idea how I get the post processor to output in this format - I've been manually editing the post for now. I have CAST and a subscription to igetit but something isn't clicking for me. Thanks in advance.

Although this may seem to be a basic task many machine tools define fixture offsets different ways and users are even more creative in how they want them applied. See the attached post. What I did was to create a new WORD ( N/C Data Definitions – WORD tab in Post Builder) called E_1 by copying the G word and changing the Leader to E.
On the Rapid Move event I added the new E_1 word to the first block and edited the output to a user defined expression $mom_fixture_offset_value So now when a 1 is placed in the Fixture Offset field of the MCS the output looks like this.
G00 G90 E01 X2. Y4.4798 S917 M03

Hope this helps

Hi John,

Firstly, many thanks for your help.

I followed your steps and all seemed well except the fixture offset outputs as a single digit i.e. E1, E2 etc, so I changed the leader to E0 and this gave me E01, E02 and so on. Is this the correct way to get the desired output?

Regards,

Neil

OK, got it - works just fine without the leading zero, thanks again
