    Could you post a pic of your board and ES setup?

    Beautiful work Michael. I am sure the excitement is incredible.
    I just got my kit as I was leaving for South Texas, so it is in my hands but due to limited tools down here I might not start til I get home. However I am going to reread all of your posts, manuals, groups etc so I am familiar. Oddly enough it doesnt look too daunting if I can keep my kids away from the parts.
    In my experiences with Mach, odd things will start to occur and only a fresh install will cure the issues. Others might say differently and maybe a more experienced computer person wouldnt have to reinstall. I always have to. I am not knocking Mach at all, love it and its support. I just might not be their best operator :-)

    Very cool, good to see it print.
    I started wiring mine/fitting the timing belts this week, then realized I'd somehow misplaced one of the white gears that fits on the stepper motors.
    I suspect during my business trip my cats may have decided it was a good toy and wondered off with it, I spoke with John earlier in the week and he's going to send me a replacement, great support.
    In the mean time I did get X and Z wired to my RAMPS board and run through a couple of prints, to ensure everything was moving smoothly.
    You have to be very careful with the idler pulleys for the timing belts, they will not turn if the bolts are too tight, or there is too much tension on the belt, I might try stripping them down, increasing the play in the outside plastic part and using some lithium grease to see if it makes them less sensitive.

    Good point on the oilers rpovey, a few of us have been bitten by that. The symptom is a print that "jumps" left/right or front/back. That's because the belt is sliding on the roller and not rolling. The friction- especially at high rates - builds up and causes the belt to jump teeth. The fix is easy, loosen the screws that hold the idlers in place. However, if they are too lose, you can introduce backlash. The fix is to sand one end of the roller down a little. A drop of machine oil helps too.

    cheers,
    Michael

    Well, minutes after I made that last post I had a scheduled conference cal with my boss. He's in CA, I'm in MA. Short of it is, I was laid off. So, after packing up my office, I came home, told the family, and took these photos of the 3 axis driver and EasyDriver! Seriously, this is a good thing. I'm in high-tech and my division has been struggling for some time. This was the kick in the pants I needed to do something bigger & better.

    Here is the entire card with the EasyDriver mounted.I got this idea from Steve and John - use one of the fan screws to attach the ED to the heat sink. I used a 1/8" plastic spacer between the fan and board (it's a piece of the 3mm ID teflon from SeeMeCNC but any plastic or aluminum would work). You can see the opto jumpers top left.



    Here's a better view of the ED:



    And here's a closeup of the removed and jumpered diodes and the jumped optos:



    cheers,
    Michael

    "Short of it is, I was laid off. So, after packing up my office, I came home, told the family" - Welcome to high-tech in the 21st century! Last year, after having that happen twice in 3 years, I said "Screw it", and retired early. The last time was so my new boss could bring in one of his Cisco cronies, who is doing half the job I was. I now make my living making things in my shop. The boss is still an idiot, but at least I have job security! Good luck to you, I'm sure you'll find something better.

    Regards,
    Ray L.

    I am very sorry to hear that Michael , but at the same time I cant help but feel your enthusiasm and drive for something better.
    I can sympathize as I might be on the tightrope for a while, the company I work for had a very large explosion and fire a few weeks ago and we lost 60 % of our capacity to produce. This was months after upgrading the equipment on that process to the tune of 5 million$
    They say its going to be about 40 million to rebuild and about a year at least!
    We are Teamsters and I have been there for quite a while so I am 4th from the top as far as seniority goes, so I feel fairly "safe" but who knows maybe they will just shut the doors like they did to me when I worked for Tyco printed circuit group. But that was shortly after our Forbes top rated CEO got indicted for embezzlement in 99-00'

    At least no one was killed, but we had a guy that had to be ladder trucked down 110ft. Out of a powder silo. He had pretty bad smoke inhalation and some minor burns but he's alive and kicking. I work in the engineering dept. with his father who coincidentally is the one who first got me interested in diy cnc.

    He is building a 3d printer as well.

    Michael, I wish you the very best during this transition. Judging from your writing skills you might have a few avenues to pursue. Your help and contributions here have been fantastic. Thank you very much in case I hadnt said it before.

    Thanks guys, I'm going to take a week to play and then look for a job! Already had a VC contact me (!) and another startup called yesterday to meet me for coffee next week. It's a start!

    Cheers,
    Michael

    Good to hear, you can't keep a good man down.
    Best of luck with the new job pursuits, you'll bounce back in no time.

    Hey thanks Hoss. I have a few more things to polish off on my G0704 (remember those machines!) so the time will be well spent.

    cheers,
