      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

        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.

        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

        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.

      Hi Mark, sorry if I bother you again! I have a question about the OX CNC and GT3 Belt, i have see that on the openbuildpartstore the gt3 belt have 5mm width, but in other openbuildparts reseller have 6mm width, what is better for the OX and the v-slot? I want use 4 Nema 23. Thanks:)
      1. Mark Carew
        Mark Carew
        No bother @Piero87 We use the 5mm so that if you want to us it as belt and pinion system where the belt lay in the track it will not rub the sides. We have used both and its really no problem to use either, in fact we have widened the C-Beam track to allow for 6mm belt so its really just whats available to you . Keep up the good work! :)

      Hi Mark, i have posted a message in the OX CNC Discussions, about the screws to use in the OX CNC. I have looked your build video on YouTube and for example in the video you use the M5x10mm screw but in the parts list i doesn't see that screws, have you got the complete list of screw that need to build it and for where to be mounted? Thank you very much for this amazing project!

        The community builders like yourself have done an outstanding job at helping to make the OX build more complete then ever though feedback and we thank you so much for that.
        It may be helpful to know that between the 8 and 10mm screws in most cases they can work in the same instances.

        You can flip the tee nuts upside down and this allows you to use the 8mm in at 10mm spot as you gain a couple mm in the flip with the tee nuts threads at the top of the channel instead of the bottom. I think this may be the case with this build. Some of the newer builds we are working hard to make sure the list are more complete or bundled when available.

        Hello Daniel, We are working to have the numbers for the actuators released soon. However I think with the screw driven C-Beam™ actuators you show in the animation you will have no problems lifting a 10kg mold. You have a nice setup there and we look forward to seeing you share this Build on OpenBuilds.

      Hi Mark
      I got a X-Pro driver board from you guys. Using Grbl Panel when I try to change the settings in the x,y,z stepper it won't save the settings. 1-2-3-etc clicks to save it to the board. Since I got no ideal what settings to use on the P3 printer. Some of the times it saves the new settings, but most of the times NO tied many times?? The same with the other settings.
      1. Mark Carew
        Mark Carew
        Hello Bob, I know what you mean its tricky and at first I went in circles with that one :) According to the grbl panel wiki on how to save the setting to the card "You can change settings by clicking on a Value, altering the value and then double-click to send the value to Grbl." found here - https://github.com/gerritv/Grbl-Panel/wiki/Settings
        Hope this helps got you back on track with your Build Bob

        @dakman you should ask this in the forum maybe under the general section so that the community can respond. You can always connect V-Slot end to end for longer lengths.

        Mark Carew
        Hi @JFAirplane I would recommend going with the steel track and the Steel V Wheels if your design calls for the outside track concept. But as you can see from all the builds here you can also build your machine using the Solid V Wheels and get the same results. So really is its a matter of design preference.

      Recently bought the c-beam kit. In my attempt to assemble it I discovered that one of my precision shims in the wheel kit is NOT a precision shim! How do I go about getting a replacement so I can continue my build?
      1. Mark Carew
        Mark Carew
        Hello jrclarke sounds like you may have a defective shim. Its rare but does happen from time to time. The best thing to do is contact the Part Store Team and they will take care to get you up and running right away. [email protected]
        Thank you

      Hi! I just assembled my new CBeam machine. I have the steppers wired to a Tinyg and now I think I'm reading there's no more TGFX? I actually have no idea what I'm doing, What I should be looking for as far as (a program to run the machine)? I would rather not run CHillipepper because I don't often have a reliable connection. I'm at the beginning. Could you please steer me in the direction of progress?
      1. Mark Carew
        Mark Carew
        Hello, I have not tried the Tinyg but I would think that you could use it with any grbl control software like grbl panel . Please have a look at the Software section of the build - https://www.youtube.com/watch?v=HVR8pABCHXI&feature=youtu.be&t=4152
        You should find everything you need in the Files Tab of this build for software as well. Hope this helps

      Hello I am a virgin in CNC builds and have one question of many on my first build, can I hook two steppers to one driver for my y axes? so what board would I need a 3 or 4 axes? All of this is getting a little over whelming for me.

        Its really not complicated at all, once you dive in it will all begin to make sense and next thing you know you will be designing your own machine :) Be sure to use the forums to post questions as this will help others that come along later with the same questions. Have fun with your Builds!

      Hello Mark, I would like to make or buy a cheap XY stage for my microscope. I have not played with stepper motor before. What is your suggestion? thank you
      1. Mark Carew
        Mark Carew
        Since there is no real load on the system I would say that you could go belt drive but lead screw with an anti-backlash nut block would be nice as well. Really I think you will have to take a look though the great Builds here on OpenBuilds and try to decide what will work best for your application. Wish I could be more help but I think it will come down to personal preference on this one,

      What is the advantage of having a 24 v power supply over 12v?
      1. Mark Carew
        Mark Carew
        A 24V supply will charge the stepper coils more quickly and give a little better over all performance.

      Hi Mark! I just assembled the c beam kit and I had problems with some parts.
      the spindle mount is not threaded properly for the screws and one of the lock collars has the same issue with the screw.

      Mark this is all new. I found you on you tube with c-beam, great video and I know it took lots of work payed off you found me. I'm very hand on and mechanically inclined. This will be my first build and first set up to learn in and outs of CNC. My question is, can I build the c- beam cheaper if I piece it together with your parts store or just buy your bundle kit?

      In your page for the OX you have instructions for a Spoiler board. In the instructions it talks about Hold Down clamps that will be available in the store. Have you added this item to the store yet? I did not see it when I was looking.

      Mark, I am going to build a large C-Beam based CNC Router. I want to use a 750 mm X axis with a 1500 mm Y using 2 C Beam spaced 80 mm between the 2. I need help with the best way to locate the NEMA 23 motors. I would like to use an ACME on the Z with at least 6" of cutting height. I need help with this design and all the parts required .
      1. Mark Carew
        Mark Carew
        I think the best thing for us is recommend is that you start a build here.
        Here on OpenBuilds®, you will have access to valuable feedback from many like minded individuals and Builders as well as resources and tools that can't be found anywhere else.

        Thank you

      Hi Mark: Is the (CNC xPro V2 Controller Stepper Driver) a good replacement for the electrics that came with the Plll?
      Its still working ok but failer may be around the corner.
      thanks bobada

        Yes Bob I think the xPRO would work great for the PIII
