Hello all! I was going to introduce my self in the Intro. thread but I had a few questions as well so I figured I'd start a new one.
My names Mike, I am from Michigan, work construction, and enjoy the outdoors. I was put in front of a CNC machine bought off ebay that didn't fully work and told to figure it out. Well, like many, I've never dealt with a CNC machine or heard of mach3(which was already installed). The person he had working on it before said they had to mix the XML files from two different versions of mach 3 to get the machine working at all. That raised my eyebrows from the start. Well I went with that persons revised XML for mach3 and after some tweaking in Mach 3 have got it to make code for DFX files using Sheetcam and STL files using Meshcam and then carve using mach 3 without too much problem except two that I can think of right now.
1.) I need to calibrate my Machine with Mach3, so I go to steps per and as I adjust I get up to 25000 for my Y and can't go any higher, which is a problem because for every 10 inches it only goes 7.7 in. so I'm stuck on where to go from here? Idk if something else can be adjusted or if its in the xml or if its the machine. I just hate that for every image I want cut out I have to plan on it being 77 percent smaller than what it says it will be. Any help or suggestions?
2.) Every time I load my G-code from sheetcam or meshcam, the image will be VERY small on the table display on Mach3's screen but it will cut out the images big(77 % of what I tell it be). Any help here?
Thanks for any help in advance, I will be on here often for help now and hopefully eventually helping other people.
