Carl is right. Make sure you save an original copy of the post first. We use MPHUR.PST here which is included. Actually I think we installed it in ver9 and upgraded the post version to X. So that's no help if you're starting at X. The reseller (hollow be his name) was no help at all. Only the good ole boys at CNC came through for us. The result: no maintenance - no upgrade - no sorry! That whole YZ plane thing affects more than Hurcos. It's a european thing, kinda like how they view their drawing I guess: backwards. The salesman said to use Industrial Standard but I've always used Basic. Had to tweek the post to get rid of the G75 at the start and only later ran into the loop de loop. Better than Pepe le Pieu! I haven't had any problems losing TLOs but we're using a VMX Hurco machine model. The night guy uses conversational all the time. We just try to use different tool #s so as not to overwrite them. If you need line numbers for changes I've made to the post drop me a line...

Lessee, when Windoze 2000 came out AutoDesk released ACAD 2000. When XP comes out MasterCAM releases (Kinda late) X. What will be the terms used for a Vista platform? I can see for miles & miles & miles........

GeoGirl: I have a Hurco VMX42 and it always posts linear moves for thread milling. You can select the Linearize Helixes and set for fine graduations but it posts lines regardless MartyMan

It has happened to me several times in X but not recently. I have no idea of the cause.
