Based on what is going on it seems as though the machine thinks that it is bigger than it is. When trying to run a file it goes to the back right corner, opposite of where i have home at. It then tries to keep going, what i noticed is that the yellow arrow is moving but much slower than the x and y are. I have made multiple files where the work area size is between 6 and 10". Is there somewhere that i can tell the machine what the maximum size of the work area is? i thought this was done inside of the g code, you design something in the space given and the g code tells the machine to stay within this space, am i thinking about that correctly? My 3d printer has a setting where yo u tell if the max x, y and z. Can i not do that with this? EDIT- I let something run and it does all of its movement in the back right corner, this is what it does for everything i try to run. The back right corner is the default homing location. The Steps/mm are very high at: $100 = 250.000 (x, step/mm) $101 = 250.000 (y, step/mm) $102 = 250.000 (z, step/mm) Should be: $100=40.000 (x, step/mm) $101=40.000 (y, step/mm) $102=80.000 (z, step/mm) Check the jumpers on the CNC Shield to make sure you have the right settings. (page 29 of the M3 manual.) I think we are on the right track. The new $$ coordinates did help keep it from maxing out at the top right corner. The jumpers are all positioned correctly. I just noticed that in UGS it always shows my spindle in the center of the workspace with the yellow arrow, when i load my file it then only shows the area i need to cut with the yellow arrow being at the bottom left corner. Do you think its zooming in somehow and putting the center arrow at the bottom left corner which is why it always goes to the top right corner? If that makes any sense. EDIT:It is zooming in, i can see where the red vertical line and blue horizontal line which mark the center of the workspace intersect in the lower left corner. Also, the machine moves very slowly after making the $$ changes and all motors make a weird zipper/grinding noise now. They did not sound like this with the other settings. |

"I just noticed that in UGS it always shows my spindle in the center of the workspace with the yellow arrow, when i load my file it then only shows the area i need to cut with the yellow arrow being at the bottom left corner. " UGS shows the yellow arrow in the center by default when it first starts. After you start UGS, you should Home the machine and then the yellow arrow should follow the movement of the spindle. Typically the workpiece zero (for XYZ) is the lower left. This point is selected in the CAD/CAM software and coordinates the G-Code toolpath with the actual workpiece to be machined.

This is normal for stepper motors. |

This is normal for stepper motors. I'll check out the videos. I was able to run a part with a bit. It plunged pretty deep right away, this is probably from me forgetting to set the depth in easel, I haven't confirmed yet. I stopped it shortly after starting but it does work and no longer maxes out. It is getting there! My homing switches don't work, they are plugged into the x, y and z+ pins on the right side of the red board. I turned on verbose output and I dint get any feed back when pressing them. I think this may be due to the wiring being run together, i think i read somewhere that it causes interference when doing this. |

That shouldn't happen though. Moreover, I think we can rule that out since all three of them aren't showing.
Do you have black to COM and red to NC? Com is the one on the side of the switch and and NO is the one on the bottom closest to that.

The pins on the side of the red board have the red wire on the left as well. |

As far as the homing switches go the z axis goes to the top and hits the switch then falls back to the bottom of travel then back to the top and repeats until i get an error that ugs could not home the machine.
x and y do nothing.

Looks like it is not seeing the Z axis limit switch. If it doesn't see the Z axis first it errors out the homing sequence. In UGS go to the "Tools" menu select "Options" Select the "Show verbose output" Click "Apply" and "OK" Click on the "Console" tab to show the scrolling data. Push the Z axis limit switch and look for the |Pn:Z> at the end of the data string that scrolls by. The |Pn:Z> should appear as long as you have the switch closed. If you don't see |Pn:Z> then there is a wiring problem with the limit switch. I would check all three switches while your at it. It could be a broken wire but still holding on with the insulation. Do a continuity check with a multimeter. (measure the ohms from end to end of the switch and wires while switch is on. Should read near 0 ohms) My guess is a wire is broken somewhere. Don't forget to turn the verbose mode off when your done with it.  |

I'll try that later today, it's getting close to working properly.
Do you think the homing problem has anything to do with always placing my object in the top right corner?
I was able to cut most of a small heart out, my test object from easel.
When cutting it would still max out the x axis a few times, pushing the limit switch while it does it.

Have you corrected all your settings yet? Homing issues can be related to a problem with these settings.
Beyond that, I have to challenge you to check your connections. I've not seen two switch inputs be inoperable. It is almost surely the setting issue or a connection issue.

I've not seen two switch inputs be inoperable. It is almost surely the setting issue or a connection issue. I have still not been able to get this sorted out. I checked all wiring and it is correct, i used my volt meter to test continuity from each limit switch while holding my leads on the 2 pins of each black connector that goes to the red board, i then press the switch and it tones out, this tells me the wiring and switches are good. |

I got it working for the most part, still some things to figure out, like the homing switches.

With the new version of UGS are your $$ settings still the same?
