    Thanks for the quick reply!!
    No it doesn't have support :( I need to take care of that. Help me understand what you mean on strengthening the x axis! And what can I do with my z axis?

    Dual belting is even better than going with bigger belts.

    For the Y axis you have an extremely long span with no support. This can lead to flexing side to side. I have a 1500 mm 20x80 vslot beam like you, but mine is supported the entire length of the beam vertically, and it is tied down to the table top the machine is on so there is no side to side movement.

    Picture of it under construction:

    To strengthen my X axis, I had a friend print me some of these to help with alignment then I bolted two 20x80 vslot beams together.
    [​IMG]

    I used a c-beam for my z axis and have 8 wheels on it. However, I also build my spoilboard up by adding layers so my z has to drop less for most things I cut. This helps to minimize flex in the X/Z Axis. If I need the full depth of cut, I can remove some of these "layers." This is especially helpful for aluminum work. Another thing that helps me reduce flex is that my x axis is only about 845 mm. My goal was to be able to cut cabinet sides if I wanted, which meant I needed 26" width. I can cut 26.5" x 49+" on mine. Some people like the longer X axis of 1000mm. I didn't see the point for me because the negatives outweighed the few times I would ever put a 32' wide piece of stock on it. And since I have built mine, I have never had a reason to cut something that large.

    If it is belted, then perhaps the larger belted 1510 sized machines should be similar, but I do not know what components (pulleys, etc...) you used in your build or what microstepping setting you chose. However, everything you need to know about how to configure your build and calibrate it is right here: gnea/grbl

    I used 1510 for a base line and adj. xyz through accrual stroke of gantry's. Open build with spark controller v4 and drawing with xcarve pro is like a dream to use and execute. Great hand shake between programs, no stress

    Hello guys.
    Sorry for my bad eng.
    Please help me.
    I'm already confused.
    I bought ooznest ox cnc on aliexpress (bulkman 3d store).
    1000 * 1000
    And also bought a set of Lolette NVUM V2 and drivers TB6600.
    I collected all the mechanics. And stretched all the wires.
    But with the tuning microstep and "motor tuning"(mach3) - does not work right.
    My machine:
    Belting.
    Belt - GT3.
    GT3 Pulley - 6.35 / 20T
    Motors - 23hd56001y-21b
    Chinese drivers TB6600

    I need to properly set up Microstep on drivers.
    And in MACH3 adjust motor tuning set up.
    the seller has a setup guide.
    But there only for lead-screws version.
    I have the version - belting machine.

    Please contact the vendor for support. What you purchased was neither an Openbuilds nor an Ooznest product and is not supported here and there is a strong probability that the copy of Mach3 you received it not legitimate either. While we strongly believe in open source we do not support fraudulent activity.

    [QUOTE = "Azamat O, post: 81091, miembro: 32624"] Hola chicos.
    Lo siento por mi mal eng.
    Por favor, ayúdame.
    Ya estoy confundido
    Compré onocnest ox cnc en aliexpress (bulkman 3d store).
    1000 * 1000
    Y también compró un juego de Lolette NVUM V2 y controladores TB6600.
    Coleccioné todos los mecánicos. Y estiró todos los alambres.
    Pero con el microstep de ajuste y el "ajuste del motor" (mach3), no funciona bien.
    Mi maquina
    Correaje.
    Cinturón - GT3.
    Polea GT3 - 6.35 / 20T
    Motores - 23hd56001y-21b
    Conductores chinos TB6600

    Necesito configurar correctamente Microstep en los controladores.
    Y en MACH3 ajustar la configuración del motor.
    El vendedor tiene una guía de configuración.
    Pero sólo hay para la versión de los tornillos de plomo.
    Tengo la versión - máquina de cinturones.

    Guys plz halp me.
    Have (belt version) OXCnC 1000*1000.
    And have skew Y+A axis.
    In the extreme forward position, from the side of the axis "A" there is a bias. As in the photo.
    In the extreme rear position (slid all the way in), there is no such bias.
    p.s. sorry for my english i use Google for translate. :(

    Addition:
    I connected wire the motors to driver like this:
    Y Axis - ABCD
    A Axis - DCBA

    Addition2:
    If you raise the edge of the axis A.
    The distortion disappears...

    Are your extrusions on both side the exact same length? Or is one slightly longer causing it to be out of square?

    They are absolutely the same.
    This is a set, I did not produce anything myself.
    If you raise the edge of the axis A.

    Your build is not squared. I had a similar issue with my Workbee which you can search for in this forum. Do this simple test: find a perfectly flat surface, and try to stand your extrusions on either end. You’ll probably notice a slight wobble with respect to the flat surface. This is caused by the threading done to the holes at the ends of the extrusions; it literally bulges the extrusion around the hole ever so slightly. If your extrusions don’t have any threads tapped, then check for square (flat surface against long side of the extrusion). A slight angle will throw off you build. YouTube has a few videos of people that have run different tests on this issue and how to check for square.
    I had mine extrusions recut with a perfectly square miter saw (just a 1 mm or 2 mm) to square it. Other people have used bench top sanders, and others have used shimmies to square their builds.
    Since you bought your kit off of China, you are stuck; you have to fix in which ever way you can. If you have access to a precision metal machine shop, you can ask them (pay them) to square them for you. Do not try filing them by hand as you’ll make them worse.

    Anybody running the new Blackbox controller on an OX?

    I just got around to switching mine over from a Tiny to the blackbox. I'm looking for help with the grbl settings. I'm using the Openbuilds control software and the only preset machines they have are all leadscrew machines. It been sooo long since I set up my TinyG I can't find my notes on steps etc.

    Thanks

    For belt steps you can use GRBL settings calculator
    and then calibrate because belts stretch

    Once I finally got back to working on the OX it turns out it was pretty simple. Had to set $4=1 (enable) X and Y steps to 26.667 and Z to 200 steps. Moving around good now!

    You need to calibrate it. Those numbers are ideal everything to exact spec numbers. Move the machine to one end as far as it can go. Use the spindle/router to leave a tiny dot. Move to the opposite end on the same axis. Leave another dot. Note the difference between theoretical and actual. Repeat with the other axi. Z is a little more difficult, but can be done with an object whose exact height is known. From there just go with the feeler gauge (paper) method.

    Theoretical / Actual * Th.Steps = Ac.Steps

    The longer you make them the more flexible they get which will have a bad impact on the quality of the cut. If you do wish to make them that long it is helpful to turn the platform framing below the spoil board 90 degrees and connect them the side rails as this will greatly stiffen the side rails. Another issue with using longer side rails is stretch in the belt. You will probably want to use a double belted setup to reduce stretch.

    Guys i need some help . I am trying to find an easy way to strengthen my z-axis on the cheap . I do have a lot of flexibility and when it comes to drillling aluminum it can't center itself. Did anyone come over this and solve it ? If so, how ?

    We need some really good photos of what you have in order to offer suggestions on modifications. Also can you identify the specific point of weakness? Is it just the Z or does flex in the X-axis play into the problem.
