        thanks on post processor as i'm qa newbie at this i find it daunting apart from rewriting the circuit board i'm trying to plot there must be a way to tell grbl every Z andZ-1 command (pen up Down etc)that Hpxx2 nc file can change to see M03 and M05 commands you have been a great help so far at least someone knows i trying

        " there must be a way to tell grbl every Z andZ-1 command (pen up Down etc)that Hpxx2 nc file can change to see M03 and M05" Not sure if it can done in grbl but, since it is a text file you could always use a good text editor that can do replace and you should be able to replace all the Z to M.

      thanks mark im new at this i built dirks curcuit plotter won,t work so i use robbitin,s servo grbl fofr plotter but when i try to draw circuit file gcode nc uses z1 z-1 pen up pen down but grbl uses m03 m05 i dont want to use different software to change gcode any suggestions please and thanks
      1. Mark Carew
        Mark Carew
        Hello @Rego it looks like you could create a post processor to convert the Z moves into m. But if like you say you don't want to change the gcode you best bet would be to ask for this support on the robbitin github - https://github.com/robottini/grbl-servo/issues
        or ask how Dirks did his, my guess is that he did a pp from the nc file.
        Apr 18, 2017
      2. Mark Carew
        Mark Carew
        You could use a simple text replace editor as well and see if you can do a batch change of all instances of m3 an 5 to z moves essentially what the pp would do. Hope this helps. If not please ask this question on the general questions thread and someone will be happy to help - http://www.openbuilds.com/threads/open-build-parts-for-sale.9096/

      To Mark Carew. Sir I was watching your great video on how to build a CNC machine, the full one. You said that there is software on your site, I CAN not find it, could you help out, I also liked the drawing you had. My build is exactly like yours, I followed every thing, I had to watch the video 6 times, you said the type of board you are using but I could not hear what you said,

      I have a C-Beam what power supply should I use 12v or 24v
      thanks
      1. Mark Carew
        Mark Carew
        Hello Chrisyln, I would suggest the 24V it will charge the stepper coils quickly and work well for you on the C-Beam Machine.

      Hi mate
      I buy XPro v3 controller and I have problem. On the smoth corners tweak(shake) when run slow. I can't run fast because I made some of carbon fibre and small shranks. Any ideas?
      I run my OX like
      $110=500
      $111=500
      $120=10
      $121=10

      Hope and trust you are doing OK.
      I have recently purchased a 2.2kW spindle and VFD.
      With particular interest in the 40 x 40 V-Slot: Is there any chance you might expand the range to include a 40 x 80 V-Slot ?
      Would the standard 80 x 20 and or C-beam be strong enough to cope with the stresses generated by the 2.2 kW spindle?
      Regards
      1. Mark Carew
        Mark Carew
        There is the 40x80 C-Beam . From what I can find the 2.2 weighs about 8kg (17lbs) so that is beefy for sure and more then likely overkill for the type of work we do here. But you can never how too much power :D My suggestion is to use 2 C-Beams in parallel on the X axis using the 2 C-Beam XL plates mounted together with a plate for mounting the Z axis.

        Really though with a modular system like V-Slot your best is to scour the forum and talk to the guys about ideas they may have as well. All the best with your build. Looking forward to seeing it.

      I placed an order and it went to pending, then I had to add a cpl things to it so it went back into awaiting fulfillment. First they were quick to respond to emails, but now they won't respond at all. 4 unanswered emails since Friday. I know this isn't the place for this, but since they won't respond to any emails I didn't know what else to do to get some kind of attention brought to this matter.

      Hi Mark
      Just finished my first build. The C beam xl. Great kit from the uk supplier ooznest also fantastic support too. Looking to start wiring up so reaching out for some help around the Grbl setting for v3 board and the xl. Also siting and setting micro stop switches and the whole concept of homing! Any help would be really appreciated as looking forward to sending first Gcode

      Hello Mark, I am new to this forum and to the CNC world. I love woodworking and want to see if CNC is something for me. Trough you video's and part list, owning a OX is a realistic option. What i find difficult is where to start? I don't have the budget to order everything at once. Do you have some tips how to begin, what to do and not to do? thnx JW

        Hello @dennisn8tkk we do not have an adapter available on the Part Store as of yet. But in the mean time you could 3D print one. There are a few different ones in the Resources that may help

I am absolutely new to that CNC Topic and would like to know, what max feed rate and acceleration the OX CNC with the CNC X Pro Controller board can handle? I want to use 6mm flat end mills with XPS foam. Thank you in advance, pitily found nothing in the Manual and here in the Forum. Greetings and a succesful new year 2017, Stephan

        There are always other factors that will changes these settings mainly how the machine is built , but this is a good starting point. Hope this helps, be sure to ask questions in the discussion thread of the build (tab at the top) so that other will learn as well. Thank you

      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!

        Mark Carew
        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)

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