      press the key with the windows logo and the letter r on the keyboard at the same time then type "devmgmt.msc" without the quotes then go to Ports (COM AND LPT) press the arrow next to it you then should see the arduino name and its com port

      I just about have my OX CNC assembled. I bought an Arduino-grbl shield combination with the kit I bought from Vslot. I'm having trouble getting my computer to recognize the Arduino. I'm trying to use grbl controller but it wants a Port number ... I don't know how to find that or what to do next. Please direct me to somewhere or someone who can help.

      I'm using Windows 8 on a Microsoft Surface Pro

      I recently bought a phlatprinter 3 and some of the mdf parts were damaged in shipping. Will any of the files will be posted here so i can replace the broken mdf parts?

      It should only pull the amps needed but with a higher voltage your motors will engage a little quicker

      I was wondering what the best power supply to run this build is?
      I was running a 24V/20A power supply... Somehow the MOSFETS blew out when i plugged it in.
      but as my driver board only allows 2A on each stepper, is this really necessary?

      What are the advantages to having a 24V power supply over a 12V on this system?

      thanks for your help!

      I have milled 6061 on my machine

      Johnny, steel is tough stuff and when you get in to that kind of milling you will need very powerful spindles and very rigid machines.

      What is the hardest metals used? I know aluminium can be used but is there a limit in type of aluminium?

      Can a thin wall steel like 4310 1.5mm thick be milled
      Could I mill a tube, to make head tube badges for bikes, basically cut an images out of a tube?
      I'm using a good Dremel 4000 as cutting tool.. Will this be ok? One area I'm worried about is the drill bits and measurements of bits in SolidCAD while generating the G-code

      Hi I was just wondering if you could answer a few questions for me, about hardware I do modles in solidworks and am learning SolidCAD

      I'm in a wherlchair and design bikes for high level spinal injury, hoping you can ?

      All you need to do is start a build or ask on the forum. All the best with your build!

      I'm in Hillsborough nj, and have a specific project in mind which includes a rotary attachment. I have a few questions and don't really know where to begin. Is there someone I can call to begin a conversation on how to get started?

      I did see your posted and replied. Not a design flaw :) Yes on the wheels please send an email to [email protected] Thank you
    26. DistortedDesigns
      Have you seen my post about the new 20mm gantry plate? There is a design flaw that needs to be addressed. I have a couple of the full sized solid v-wheels that have very small chunks missing where it hits the rail. It is causing a noticeable stop as it rotates. Like having a flat spot in your car tire. Can I exchange these for new ones?

      Hello Mark, I recently purchased some small parts from an open builds distributor called snbinc.ca. Sadly I have contacted them 3 times asking for status on my order, each time no reply.

      Do you have a telephone number or do you know if this company is still in business.
      Any help would be most appreciated... https://snbinc.ca/store/products.php?27

      Many thanks, Steve
