General Mach Discussion / Mill going off centre
« on: February 11, 2013, 12:17:48 AM »
Hi there.

I'm relatively new to all this cnc and milling stuff but after a lot of research and tips from people here I got things up and running.I'm currently using a desktop milling machine to cut pistol grips.I can cut 1 set out of a single piece of wood,first doing the top side,flipping it over and cutting out the underside and here begins my problem.

Instead of constantly changing drill heads, I cut out about 10 sets for the topside,change the drill and cut out the underside,but somewhere along the line the machine seems to go off by a few mms.I go to home before I start every piece.It's only when I cut out the underside that I see the holes not lining up.Is it possible that home is changing by itself ?.I've tried doing topside and straight away flipping over to do the underside and it turns out perfectly which means the code is good.It just seems that if I do a bit of repetitive work that it goes off.I noticed yesterday that from the 10 sets I made,the first 5 or so were perfect,after that it seemed to be going off a little bit more with each new set.Anybody any idea why this is happening ?

Thanks

Vinny

General Mach Discussion / Noob question.
« on: January 08, 2013, 10:16:09 AM »
Hi there,

This is my first question so please go easy on me.I've searched the forum for some help with what I'm trying to do but I'm not really good with all the terminology.Obviously I'm not as smart as I thought I was  :P

I recently purchased two mills.There's no markings on them so I presume the guy made them himself.I've got Mach 3 installed on both computers connected to the machines.He gave me a few files to get me started but now that I want to make my own designs,I'm totally lost.

Basically what I'm trying  to do is make wooden pistol grips and then put a logo on them.I have a few files that will cut out the grips but that's where it all comes to an end.After that I know I need to make another file with a design to etch onto the grips,but to be honest,looking at all them numbers scares the hell out of me  :o .Is there anyone out there willing to help this poor noob get a headstart.

Cheers Vinny
