      Hi Mark, I wanted to know if you could send me the link to the ox plate files. Had them, then lost my thumb drive they were on and can't locate that link I used when I purchased my c-beam bundle. Would like to upgrade to the OX build. Thanks.

      Dear Mark, while browsing along I noticed that you had completed a C-Beam bundle. I have just bought one of these, and was wondering, if you would answer a couple of questions. Thanks for replying. Bill H.

        Bill, the fastest way to get the info you need is by posting to the Discussion Tabs or the C-Beam machine. We have some really great Moderators and Resident Builders who are happy to assist!

      Hi Mark,
      I live in Belgium and it is difficult to obtain the Open Builds hardware.
      The hardware is never sold here.
      Greetings Jones

        Hi David! Wow long time brother :) Good to hear from you.
        If you email the Part Store directly they should be able to get you taken care of on the Mach licence. Contact@OpenBuildsPartStore.com
        Hope this helps get you back up and cutting,

      Hi Mark, I have a question about the C-Beam, I don't plan on it being a plate maker but I want it for engraving and inlay work on my custom cutting boards. On your build you used a 12" X 12" piece of MDF . I want to increase the board size to 14 1/2" wide! Any problems??

      Thanks very much!

        Hello Stephen, I do not see this being a problem. You should be able to expand the machine a little more without having to add another Y axis and for support you could just use a couple more V-Slot rails on each size of the Y axis. That a look that Moags C-Bema Machine XL for some ideas - http://www.openbuilds.com/builds/c-beam-machine-xlarge.3675/
        Hope this helps, all the best with your Build!

      Hi Mark

      Just want to bring your attention to a small spelling mistake on your OpenBuild C-Beam Machine Build page.

      You wrote:

      "If your interested in purchasing a C-Beam™ Machine Parts Bundle please click here."

      ...when it should of course be...

      "If you're interested..."

      You + are = "you're" (contraction) and not "your" (possessive noun)

      Hi Mark,

      Great article and will be building this week when remainder of parts arrive.

      Quick observation that the OX Build parts list states 13 13 Eccentrics and the build doc states 20.

      Graeme.

        Thanks for the feedback Graeme. It should be 13

      Hi Mark,
      I just placed an order for my first build and the only thing I think I need now is a 2:1 linear actuator reduction plate/gears/belt/etc... Can you tell me when these will be available?
      Thanks!,

      Mark I am interested in outsourcing a machine design using openbuild parts. Is there a way to contact users to gauge interest and/or capabilities?
      1. Mark Carew
        Mark Carew
        Hello PCZ, I would suggest finding a Builder who has already posted a Build that is closet to what you have in mind for your application and ask them though a message if they would be interested in creating a custom Build for you.

      Hi Mark I am completely new to to this forum and was looking at the basic C-Beam but then came across this X-Large project which is ultimatey what I would have developed the basic model into. My question is, is this X-Large version too much for a complete novice? What would be the estimated cost of the kit bundle plus electrics?

        To add to Mark's comment, our test machine was built by a novice. The build manual was so detailed that he was able to complete the build on his own in what would have been less than a weekend!

      I'm looking for advice on building a small XYZ station. We will be using it to probe and test circuit boards which are in a 5" x 6" array panel. Almost no torque requirements other than to move the assembly and maybe 1-3" Z travel to probe the board. What's your thoughts on coming up with the most cost effective solution since we plan on building several of these. Any helpful pointers would be greatly appreciated.

      Mark,

      I am working with the lead screw linear actuator system and I am really looking for a 1500mm length of the 8mm diameter lead screw option that is available through this website. Is there any possibility of that being an option? The application that I will be using it for is a little custom so the rigidity of the 1500mm length wont be an issue.

      Thank you for your time.

      Mark, I'm sorry to bother you but I have no more turns to make. I purchased Mach3 and keep in mind I have no experience with CNC yet, I got a TinyG. I want to use mach3 but I found out it is not possible. what are my options? I cannot use chillipepper because there's no internet connection in my shop. Should I change controller board to something more Mach3 compatible? any suggestions?
      1. Mark Carew
        Mark Carew
        Hello Eddyg I have not used the TingG but I do remember the tgFX controller software that was being worked on some time back. It has been replaced with Chillipepper but its still there and you may find a way to use it.

      Hi Mark, newbie to the forum
      was thinking of building the Big OX 1500 x 1000 you have in the CNC section.
      I have a cheap chinese cnc but want to build something a little more serious.
      I mainly cut aluminum , carbon fiber and g10 was thinking of using a 2.2kv spindle would the current gantry handle that?

      I have found your parts list but i'm not sure what i would need to swap out to make it more robust?

        Hi Tony, welcome to the OpenBuilds community! I would suggest looking at some of the new Builds that will be using the C-Beam XL plates they are really nice and have a lot of flexibility when building.
        http://openbuildspartstore.com/c-beam-gantry-plate-xlarge/
        We have a couple example builds posted and soon (working on them) will have more including their bundles. Hope this helps

      Hi Mark- I'm trying to build a linear pumping system. For best results the table must move (in only 1 axis) about 60 inches per minute. Can a lead screw type drive move this fast or should I try the belt assembly? Total travel is about 6".

      If you add the HT Series Stepper to this actuator you can get more like 60lbs

      The NEMA 23 with the screw drive can lift about 25lbs max with the standard motor.

      Hi Mark:
      Question, the lead screw 8MM seems smaller in diameter. When you torque down the flexible coupling, pinch side of the acme screw
      it won't hold the torque to the shaft. Plus the bearings have a lot of play on the screw when mounted to the end plates???

      thanks bob
      1. Mark Carew
        Mark Carew
        Hello Bob,
        the lead has been retooled slightly so that we did not need to sand them down to fit the 8mm bearing ID if you have side to side movement this will not affect the movement of the actuator other then some noise that can be dampened with tape.
        May 24, 2016
      2. Mark Carew
        Mark Carew
        As for the flex coupling not fitting properly you will need to make sure to tighten the clamp all the way down tight and take a look close at the coupling as (if they are the new version) you should see another set screw that locks it to the shaft once the clamp has been tighten down.

      HI Mark, i am building a OX cnc Xpro v2 cnc. i am able to move all the axis, when i try to draw a circle with a pen in Z axis. its plotting as Oval :). Please help me out. i use 24v supply and nema23 OX 500X750 config, my reg setting is listed below. i use Universal gcode sender V1.0.9
      1. Mark Carew
        Mark Carew
        Hello Hariharan,
        Usually the case here is a slipping pulley on one axis. So I would suggest that you first make sure that the pulleys are one with the motor shaft. Even the slightest bit of looseness in the system can cause this kind of machine behavior.
