topic Re: Haas Post Mod - Position Table @ Center of Machine in HSM Post Processor Forum https://forums.autodesk.com/t5/hsm-post-processor-forum/haas-post-mod-position-table-center-of-machine/m-p/6103574#M28190 I agree on the use of machine configuration, but it still doesn't handle the units correctly for me...and some of the support guys are recommending hard coded changes... <BLOCKQUOTE><TABLE border="1"><TBODY><TR><TD> I had a bit of an issue with the above piece of code to change my end of cycle position. I fixed it, but forgot to update the thread. Upon taking it a step further, I ran into another little glitch... First, the above did not work because it was just trying to change the 'intermediate position' that G28 (return to machine home) uses as it is a 2-step routine. It moves to a specified intermediate position before continuing on the the machine home. Of course, that was not what we were getting at. The other way is to use the G53 command to shift to machine coordinates, and then specify the desired end of cycle position. Upon digging into the post, I found that it is certainly already set up to do so. It was just waiting on some variables to be defined to initiate the alternate output... <PRE>  if (!machineConfiguration.hasHomePositionX() && !machineConfiguration.hasHomePositionY()) {     writeBlock(gFormat.format(28), gAbsIncModal.format(91), "X" + xyzFormat.format(0), "Y" + xyzFormat.format(0)); // return to home   } else {     var homeX;     if (machineConfiguration.hasHomePositionX()) {       homeX = "X" + xyzFormat.format(machineConfiguration.getHomePositionX());     }     var homeY;     if (machineConfiguration.hasHomePositionY()) {       homeY = "Y" + xyzFormat.format(machineConfiguration.getHomePositionY());     }     writeBlock(gAbsIncModal.format(90), gFormat.format(53), gMotionModal.format(0), homeX, homeY);   }</PRE> So I went in and made some edits for my machine and got it passing things through and posting the output that I was after: <PRE>N1300 G28 G91 Z0. N1305 G90 G53 X-15. Y0.</PRE> ...But the issue is that in order for my to get the above to output X-15, I had to divide that by 25.4 as it is passing the millimeter equivalent into my output file (X-381.). This seems to be a bug as everything else is specified in inches and I've seen no other metric values. The value that I needed to enter to get X-15 is shown in the dialog box. Note it says inches in both places on that screen also... <A href="http://s358.photobucket.com/user/cabrydon/media/Capture1_zpsf4cb5f78.jpg.html" target="_blank"><IMG src="http://i358.photobucket.com/albums/oo27/cabrydon/Capture1_zpsf4cb5f78.jpg" /></A> So I have things outputting great otherwise, without having to manually edit right now, which is wonderful. So I am not sure if the above issue is user error or not; at my competency level with HSMExpress it is difficult to discern. The home position I am defining also keeps resetting. Is there a 'master' machine config because it appears as though my edits only affect that particular job. How do you access it otherwise? Can I just define these parameters on the post somewhere? </TD></TR></TBODY></TABLE></BLOCKQUOTE> So either my post is messed up or there is something else going on here...
