If you have a bunch of cuts close togather the post won't bother to re-reference for each cut. Near the start of the file you will see a bunch of parameters. The floating head only bloody works! Select the post then click on the 'edit post button'. Thanks very much for your help with this matter. Re: Floating head auto-zero set-up confusion. If I were to edit this file, where in hecks name do I insert the few lines of code? If I should use the 'run a code snippet' thing in Sheetcam then how do I get it to run in the right place? Thanks for your time. Am I using the correct post processor for a machine with a floating head? That is where the trouble starts! I am out of my depth here and could do with a few pointers in the right direction. I looked up the post processor that I'm using Mach3 Plasma and opened it with windows notebook. I copied the code that I found on this forum N G The problem The code seems to run right at the start of the cycle and not on the pierce as I require. I have got my own head around the fact that I need to insert some lines of G-code into the program so that the head will wind down to the limit switch and reset the 'Z', then wind back up a pre-set amount and then move to pierce height. I did some research into auto zeroing the Z axis and found several posts on the subject.

So far so good, physically the head works and I can move it so it actuates the micro switch and illuminates the LED on the diagnostics page. I decided to start with ie, before I get THC I would build a floating head so that the machine will 'auto-zero' before each time it pierces the material. Please, somebody, Having problems with or questions about SheetCam? Post them here. Floating head auto-zero google my maps tutorial confusion.

Sheetcam very slow
