    Re: Omax Maxiem 1530

    I think my machine was originally built with gears but was converted in the field to belts.

    It is interesting that the 3 non-working boards are part number 309810 rev B and the 1 working board is...

    Re: Omax Maxiem 1530

    Hi Neil,
    I am still working on this problem. As I mentioned, my Z board is good and the other 3 throw a fault. The 3 bad ones have a different firmware revision than the 1 good one. Could that be...
  3. Re: Leadshine technical support available on CNCzone.com

    I am fixing a GWeike laser engraver for a friend. The two Z axis steppers just vibrate back and forth. The LED on the Leadshine ME872 stepper driver is green. I moved the cables to the Y axis and...

    Re: Omax Maxiem 1530

    I did a thorough series of swaps and determined that the X1, X2, and Y servo control boards have a fault, and the Z axis board does not. I measured the voltage across the H bridge resistor and the...

    Re: Omax Maxiem 1530

    I used the new cat5 cable to connect the X1 position on main controller board to the y-axis card on the gantry. The X1 red light did not come on.

    When clicking the fault detail I get a Y-axis...

    I swapped the encoder cables from Xf to Xr. No effect.
    I swapped the encoder/motor cables from Xf to Z and swapped the DIP settings. No effect.

    The errors do not reset when pressing the black button on the pendant. Here's a summary of all my testing, which I've just repeated. To make sense of the logic, I've called the factors Gantry,...

    On power up, all the lights are red.
    When pressing the green reset button, they go to the state previously described (X1 green, X2/Y red).

    Re: Omax Maxiem 1530

    This is a Gen 1 Maxiem. We repaired a bad connector on an encoder, and setup the gap to the encoder strip, and now the lights on both Xs and Y are green. The lights on the stepper boards are all...

    Re: Omax Maxiem 1530

    Great diagnosis! All the encoders were green except X2, which was red. I swapped the encoders between X1 and X2 and X2 stayed red when plugged in to the X1 position.

    Not sure what you mean by...

    Re: Omax Maxiem 1530

    A year, and a worldwide pandemic later, I'm finally getting back to this machine. I had to put it in storage for a year for a number of reasons. Anyway, got a rotary phase converter to run the...
  13. Re: How do you meet your 3 phase, 480V needs?

    I have a 600 amp service. I stepped through Phase Perfect's wizard for selecting a converter but they don't sell one large enough.

    What are the advantages/disadvantages of stepping up the voltage...
  14. How do you meet your 3 phase, 480V needs?

    Just bought a used omax maxiem waterjet machine with a 40HP, 3ph, 480V pump and am starting my research to get from 240V to 480V and single to three phase. It came with a 75KVA transformer to go...

    Omax Maxiem 1530

    I purchased a 2013 Maxiem 1530 this week and have a few questions if you have experience with this machine or similar:

    1) Omax says I need to remove the gantry prior to moving it and that...

    Re: Machining arcs

    I think I have finally solved this and it looks like you were mostly right--WinCNC parameters in the .ini file. Here's the optimum configuration which effectively eliminates a 'bump' at the...
  17. Re: Plasma cutting thin gauge stainless steel

    I have the table and spindles to do that. I don't have any experience doing it though. What end mill, cut speed, and cut depth do you run at?
  18. Re: Plasma cutting thin gauge stainless steel

    Just had a thought--I could use thin aluminum sheet in my application, instead of stainless. Would plasma cut aluminum with a clean edge, or would a secondary op still be needed to clean it up?
  19. Re: Plasma cutting thin gauge stainless steel

    I bought a small engraving laser a few years ago directly from G Weike in China and was pretty satisfied with the machine and the support. I've been looking at this one: 500W Fiber Laser

    which is...
  20. Re: Plasma cutting thin gauge stainless steel

    Thanks for your input. I was afraid this would be the answer but I needed to hear it from 'expert witnesses' before I went down this path to determine it won't work for me in the end. I suppose I...
  21. Plasma cutting thin gauge stainless steel

    I need to cut thin stainless steel (<1mm) with a plasma cutter on a CNC machine. I have a CNCRouterParts Pro machine that I plan to upgrade with a Hypertherm 45XP, a water table, and height control....

    I agree that software maintenance is annoying, however, your analogy isn't a perfect comparison. To be closer, either:

    Re: Machining arcs

    Gerry,
    It has ballscrews on all axis, and they are an inch in diameter. The only time I seem to get this kind of 'hiccup' is at the intersection point between elements.

  25. Edge cut quality -- am I expecting too much?

    I just picked up parts which were cut from 1/2" aluminum plate. They were cut on a 4KW Mazak. The edge quality is really bad. There is a critical tolerance of +/- 0.003" called out on this part,...

    Re: Machining arcs

    Jim, I have fitted a bezier spline to the arcs and machined those. Is that what you mean? This yielded worse results.

    Gerry, good question about backlash. I hadn't thought of that, even though...

    I machined a circle tonight which was created using the same arcs from the problem file. It was perfect--no bumps at the intersections. Of course, the difference is that with a circle, the arcs are...

    Thanks Gerry. I have been doing a ramp lead in rather than plunging. I had just forgotten to do that when I created this file. The plunge is on the flat side though and the 'bumps' are on the...
