Posix: Steppers stall at about 3.6mtr/min. I've tried the micro stepping from half upto 10x and yes the drivers do go to silly micro stepping but i know past 10 is a waste. They sounded happiest at 4x stepping and double that 8x for some reason and yes each time i reset mach. No i havent got a 75V supply yet but will have shortly. Gerry: Problem with contacting the supplier!!. . . Arceuro trade are useless and know less about there...

I didn't know plastic expand...

Hey Jsheerin, I'm not Gerry but I have tried it I was able to import designs from solid works...

I am on the last stretch as I go over the design for the base structure and start buying supplies. I will start making videos in about a week after I test the design to see if it will do. I am still thinking about test the design provided in a reply (it is the second picture down where the front is cut out)

No new pics but I did get my xyz tool setting plate working yesterday. At the moment I can use it to set the z tool zero on a part or as an edge finder. Check out this excellent thread to learn more. http://www.cnczone.com/forums/showthread.php?t=56079

Thank you guys for all your help, I'm comfortable with it all now. I think I'm going to wire the 5 "limit" switches with the y-- and x-- shared as a home switch. Also adding a touch off pad for the z-- and an edge finder tool I've seen. Also an E-Stop "BIG RED BUTTON" for when I screw up everything. It's great to have you folks out there for answers and support. I'm not at all scared to build this...

Hi Steve, no, the 300 euros is for one piece of 1892mm only... I now have to think a smart way to do it my self accurately...

But for now let me "press my brain"... Thanks, Kostas.
