Need help with Mill turn offsets

[AUSTINMACHINING]

Hello All,
I just purchased Machstd mill specifically for the Mill turn capability. I can't seem to get the offsets functioning properly. I'm using master tool mode etc. I have a gang tool fixture setup and have followed the video on setting up offsets etc. The problem I'm having is the Y axis never moves regardless of any offsets in the tool table. I can jog all axis and all other hardware seems fine. When I change tools (ex. t0202). the spindle moves to the tool change coordinates, XYZ as expected, but after pressing cycle start nothing moves to the tool offset location. If I run the Gcode as is, the Z and X axis move as expected, but there never is any Y moves during tool changes. I've been through all the setup settings, but can;t find what I'm missing.

Thanks for any guidance.

Hi,
I'm puzzled by this - so lets check some basics:
1) is MSM in lathe mode? Look in the upper right corner of a page - it should say "lathe mode".

2) I want to double check what you told me re how the axes are set up -
MSM (and all the math) assumes a right handed coordinate system. So when the machine (a veritcal mill) homes to machize 0s, the table should be:
a) table all the way away from the column
b) table all the way to the right (as you are looking at the mill)
c) Z at the top of the column travel.

If the above are OK, continue to the next items:

3) what options are selected on the tooling page TC options panel?
a) TC auto TCP = ?
b) Auto XY set = ?
c) Master T Mode = ?

The Mill-turn extensions get very little use by the MSM user base; It's possible some bug has crept in that has gone unnoticed...
As a brute force test, download MSM 2.0.9 (or even 2.0.0) and install it. These are earlier MSM versions. 2.0.0 was the initial Mill-turn release. and 2.0.9 had some turn related bug fixes.
Do either of these move Y differently for offsets?

Hi Dave,
I've loaded 2.0.9 with different results, but still not functional. It does actually move after a tool change, but only in the Y axis. When you "ref all", the 2.0.9 version order is different (X,Z,Y) instead of Z,X,Y One reliable function that is repeatable is going to the tool change location. I've tried many different scenarios just to see if I can do a simple offset move from information in the tool table doing a tool change. AutoTCP Auto XY Master tool mode all on. I'm pretty lost at this point trying to get offsets to work as in you videos. I had to get a part made so I was able to by using G54 and G57 offsets for two tool locations on my gang block. I posted My cam data and manually put in the G offset locations between tool changes. I'll have to use this method until I have more time to diagnose what is going on. Bottom line at this point, is regardless of what is in the tool table, only one axis moves from the tool change location during a tool change.

hum, at the moment I can't explain what you are seeing.

Just to double check: the machine is set up for a normal right handed coord system - correct?

The difference in ref axis order is probably a side issue. There were some changes.bug fixes to that area which I did not research vs the old 2.0.9 version. I was just interested in the Axis movements deltas during the tool change.

To get further I'd have to set up mil turn again on my mill and run it... but the mill is currently down so I won;t be able to do that soon.

Dave,
Here's some screen grabs at the completion of the respective tool changes.
I noticed in your video when returning to your probed tool offset locations, there is no Z movement. Should it not go to the probed z height ?.

Hi,
I have set up a simple test for mill-turn offsets and verified that they are being applied. Attached is a short doc with the steps that I followed so that you can try to duplicate them and see what you get.

I'll email you a link to the beta version that I used for this test so that you can be using the same MSM version that I did.
