  • Here is link of the ox with plasma. Lots of great info on the Google plus groups. Recommended groups: openbuilds, ox cnc, r7, diy cnc

  • Mpcncs big brother

  • I used a lotos ltp5000, along with estlcam for writing the gcode. No issues with interference/noise EXCEPT if the torch head was firing off of the sheet of steel. This was using a tinyg controller- never tried it with ramps. I used a custom gcode command under the laser tab, to turn torch off and on. I purchased a cnc-machine torch from ebay on…[Read more]

    I’m about to to start assembling my mpcnc plasma, and I think I have most everything worked out except a cam program to post process the files, which it seems like sheet cam is the best option. Maybe some of you guys who have completed a set up or are more used to using a plasma can help me out. I’m using a lotos ltp5000d plasma, with pilot arc.…[Read more]

  • Keep us updated on how this works out for you! Maybe even a detailed report on how you set it up… Hint hint….

    I actually bought a plasma with intentions of building a plasma set up, but summer happened and time is in short supply until winter again.

  • How did your plasma set up turn out? Any issues with the HF start? Anything you would change?

    So for you plasma guys out there… what would be the “ideal” plasma cutter for using for cnc? I cancelled my order on my unit I ordered since it was High Frequency start, and I’m trying to find a unit that is a pilot arc start, to be easier on the electrical trouble shooting. The problem I’m having now, is finding something affordable, that is…[Read more]

    Do you have any more details on how to hook up the relay, and the wiring for swapping out the torch? I’m brand new to plasma torches, and haven’t really used relays very much.

  • Any update from the guys who have gotten their mpcnc working with plasma? I am contemplating building out a second machine dedicated only to plasma cutting. I ordered a Lotos ct520d TIG/Arc/Plasma combo, and now I’m thinking I will have to try to add CNC to it. It is a High frequency start, hopefully there is a work around for that and the…[Read more]

  • What is your reasoning for looking to use chilipeppr vs. marlin/repetier? I’m sure there are many good reasons I’m unaware of, but I’m having a heck of a time right now with anything other than repetier. I ordered an OXCNC before Christmas and ordered a tinyG with it because it all sounded good on paper. Chilipeppr never seems to work right for…[Read more]

  • I would like to hear your ideas on a delta printer! That’s exactly what I have been researching for some good use for the cnc mill! I haven’t found any good designs yet.

    The 3d printer is the hard part compared to getting a router working. Its just like 3d printing, except your tolerance for zeroing out machine on the work surface is much easier.…[Read more]

  • Dragonfly program for anyone who is interested.

  • It is sized for 3/4″ plywood, but if you do cut it out, I would recommend starting with the cutting tool maybe 1mm off the surface so you don’t break through with your rough cut. I should have added tabs to it. Watch the circle cut outs as well, one my popped lose, so I paused the print and pulled the piece out so the finish passes wouldn’t hit it…[Read more]

  • For the g-code for the dust shoe, I just loaded the .stl into estlcam, and pretty much let it do all the work! I used a 3/4″ piece of scrap plywood I had laying around, Set the depth limit to just over the plywood thickness, and let it rip.

    Here is what I worked on tonight. Finished up the dust shoe and got it on, and then had my wife find a…[Read more]

  • I tried printing pcflyers dust shoe twice, and twice it failed, 2 hours into 6 hours….

    So why not cut it out of wood?

    Would be a little better with square corners versus the radiused edges with a square end mill. Only took 40 minutes! Could have been faster. Probably should remember to put tabs in next time, it gets a little scary at the…[Read more]

    Oh now you tell me, I just switched steppers around! Just kidding it only took about 5 minutes, good trouble shooting test. Still the same issue. Could you give me a quick run down of how to change the acceleration? I haven’t done any previous work with programming or arduino, other than just hooking them up and they work. Thanks for finding a solution!

  • That’s awesome! What steps/programs did you use to get your file into gcode? That is a really professional look! I went cheap with my practice material, damaged mdf from menards. 3′ x 7′ sheet for $4 haha.

  • A one more thing from tonight, found a .png file on google that looked like I could make it work, used an online converted to make it a .svg, scaled it down in inkscape, loaded in to repetier and this is what came out. Would have been really cool if I had a 1.5mm mill, I have some on order.

    I ran the z-torture about 15 times, just looking and watching every part. I ended up adjusting the driver voltage up to .72v, and it seems to be the best results so far. No missed steps on the last job. It still clunks a little when switching directions, but if its losing steps, its catching up. Before it would sometimes miss a big direction jump,…[Read more]
