Thanks Gerald. It has been too chilly to paint those brackets on my conduit but I'll get around to that when the weather warms up a bit. I wish it was mowing weather around here. The wires in my control box are pretty stiff in these temperatures and the other night, I worked until my fingers couldn't feel anything.

This thread took me back exactly a year to this post. My reply to Fabrica (Udaya) is mostly still valid.
Let you into a small secret; we never the closed the hole where the parallel cable enters the box. My excuse was that it was a very scientific test to see the amount of dust ingress. Well, the dust ingress is very little. The big worry is that it doesn't look "professional" to leave it open - so I keep it as a secret |

It's alive!!! I couldn't wait any longer. All day at work, I kept thinking about it and reading the Mach 3 manual when I had the chance. Near the end of the day, I decided that I had enough info to finish configuring Mach so I ran home, jumped on my computer and finished it up. Then I told my wife that I was going to see if it works. I carried the computer out into the garage and turned the control box on for the first time ever about 1 hour ago. Then I hooked the parallel port cable to the computer and booted it and started Mach. I didn't have the springs installed so I hit the down arrow and I could see the pinion spinning. The right and left arrows made the gantry motors spin and my wife confirmed that the front side was spinning in the right direction so I decided to install the springs. Man, she's FAST!!!! Since I don't have any experience with CNC gantry routers (just a Hass mill in night technical school) I guess she might be slow compared to everyone else's but she seem FAST to me.
After reading JR's post, I decided to bump the speed up to 35,000 pulses and she seemed to operate fine. Of course, I understand that I'm not cutting anything and everything will change when I do but right now, I'm floating on a cloud. The pause and resume buttons worked perfectly. I also loaded the roadrunner code that comes with Mach and she simulated cutting it out. I say "simulated" because I don't have the router or the Z-axis hooked up yet. I still need to fabricate that small bracket and connect the router power cable. I did see the Z pinion spinning when the program told it to. Whew. I bet I don't get a minute's sleep tonight. THANKS GERALD!!!!!!!!!!!!!!!!!!!!!!! I've been dreaming about this day for years and you made it come true. I really owe you man. Thanks again. |

Doug,
What great news! It looks like you have one fine Blue Beast on your hands. Congrats on making it your MM come alive....Nothing sweeter than watching that gantry fly across the table. Funny how you mentioned "fast". I attentively watch all the "how fast you can make it go" threads it calculations never really seem to do it justice. Good luck on the rest of the build! + stay warm in the shop. (now only if those Geckos and steppers would get warmer you might have something :-O Sean |

Thanks Sean and GregJ. I forgot to thank all the other people that helped me along the way with great advice. I especially want to thank Mike Richards for being so patient with me.
Next weekend, after I finish working my long hours, I'll be cutting something. |

Congratulations Doug!
Great job.....I haven't even had the chance to even look at my machine in over a month. Looking forward to your pics and seeing your first cutting. Okay....GregJ and Sean.....who's next? |

Greg M,
It will most likely be Greg J. I have a 2 year old and a newborn to be here any hour now....so, It looks like I will be on hiatus soon-but not for long. Sean |

Doug do you want to slow it down a bit. I'm over here busting my butt trying to make chips first and this extra pressure is not helping. Just so everyone will know if I make smoke while wiring this thing, it's Doug's fault. Congratulations
Doug I think I hear your wife calling you. She would like for ya'll to go to her mothers for about 3 days........ right now |

Doug,
Congratulations!! All your effort and work has paid off!!!! So where are the PHOTOS. You can't have a new Baby with out the photos and the first cut. |

Thanks guys but I'm not finished yet. Still a few tiny details that have to be attended to. Hopefully, I'll post pictures of my first cut this coming weekend.

Its great to hear all those completing their Mechmates, some of us are just starting the gathering stage. |

Hey Doug,
Just curious why you went with the 35 tooth pinions versus 30 tooth. I think I'll order my rack and pinons, and gas spring tonight. Thanks, Greg |
#78

Greg J,
Around the time I was about to order them, I had read a couple of posts on this forum that conflicted. One of the posts spoke about using a 30 tooth and the other a 35 tooth pinion. I think the post from Doc Tanner said he ordered a 35 tooth pinion. His machine seemed to be working correctly and he appeared to have researched the matter and seemed to know what he was doing so I ordered what he did. I'm happy with them so far but I haven't cut anything. I just returned from a trip last night. This weekend, I plan to conduct some speed tests on my machine. I'll let everyone know how fast the rapids are. I'm thinking I'll try the 45,000 pulses per second setting to see what I get out of her. As they say, speed is addictive. |

I applied my logos today and fabricated and painted the Z-axis spring anchor bracket. Unfortunately, I'm still working on the spider plate and I don't want to hook up the router wires until I have the Z-axis plate bolted back into place. It's a long story but last weekend when I moved the welded on nuts, one of them didn't move enough so I had to grind it back off and relocate it. This time it is in the right place but I had to repaint the spot welds again. I also had another set back. The outside diameter of the hold down bearing for the car was too small. Dang it. At least the stub shaft I turned on my lathe was a perfect press fit. I'm still going to try cutting something tomorrow. I'll just use a low feedrate and shallow passes. Will post a pic if it works.

Doug,
Nice logo job..... I like it. |
#82

|

Oof... I am far too modest for that huge name & address Maybe I should make up some 4"x3" serial number decals that I could post out from here?
Tell me more about this please - is there a mistake somewhere? |
#83
|
|||
|

It wasn't your mistake. I couldn't find the exact bearing I needed so I ordered one that had the correct inside diameter and didn't pay close attention to the outside diameter. No big deal. It only cost $6.00 or so and I'll order a new one tomorrow from McMaster.
A data plate would be cool but I thought that I ought to give you some form of recognition for all you've done for me and the other guys on this forum. |

Here I have to admit that this also happened to me. My solution at that time was to grind a big notch in the shaft behind the bearing . . . . . . |

Doug,
Nice logo work. Did you buy them on-line or at a local shop? Looking forward to the pictures today. |
#86

|

A local shop cut the MM logos for $5 total. I placed them on the front surfaces only since the back wouldn't show. The gantry letters are 2.5" tall and the car and box letters are 1.25" tall. The other verbiage was cut by my cousin for free.
My wife and I both agreed that the logos really help to finish the machine off and add a professional look. |

I'm finally finished. Now I just need to figure out how to make it cut something. Looks like J.R. and I will finish and cut at exactly the same time. Below are some more pictures.

Dang Doug,
I think both you and J.R. should be banned from posting pictures for awhile. Great looking machine. A lot of high standards being set. |

Thanks Greg but mine is just a basic machine. The fit and finish of it doesn't compare to some of the other guys and I don't have any innovative ideas like J.R. but I appreciate your comments.

Doug,
Give yourself more credit. When your so focused on the project and have the blinders on, you lose sight of the forest. Think about your knowledge base when you started this adventure and what you have learned. Think about all the cool things your going to create with this "basic" machine. Trust me, yours (or any MechMate) is no basic machine. |
