Re: [Emc-users] Plasma Table
Jack In this case Google is your friend. There are literally thousands of ideas from guys who have done their own thing. Two things I recommend that you don't do without. 1: You must fit a THC of sorts. Especially if you are going to cut thinner materials. 2: You must fit a water bed for your own health's sake. Also you can minimize the warping if you cut in water. Do a table that can cut a full sheet. The cost will not be that much more. Most of the cost goes into the linear devices and the control system (drivers, motors etc) On 2013/09/06 04:47 AM, Jack Coats wrote: Has anyone done a DIY plasma table, or have suggestions I could find out about a DIY version?

2013/9/6 Marius Liebenberg mar...@mastercut.co.za Jack In this case Google is your friend. There are literally thousands of ideas from guys who have done their own thing. Two things I recommend that you don't do without. 1: You must fit a THC of sorts. Especially if you are going to cut thinner materials. This is easy and cost effective with THCAD card from Mesa. 2: You must fit a water bed for your own health's sake. Also you can minimize the warping if you cut in water. Cutting in water will harden the material. But I do agree that some kind of smoke removal is mandatory. Based on geographical location and temperatures in winter, downdraft table and simple ventilator that sucks the smoke and gases out of the workshop might be a solution. There are _lots_ of videos on youtube, where one can see, how others have built their diy plasma machines. Since the question is about hints of mechanical design, all the builds of Mach users also might worth looking at. I did build a plasma table with 6x2 m work envelope with a downdraft table, I could share something from the 3d model, but I consider it to be above hobby level in terms of linear rails, motors, gearboxes, so I am not sure, how useful could that be. -- Viesturs -- Learn the latest--Visual Studio 2012, SharePoint 2013, SQL 2012, more!

Re: [Emc-users] Plasma Table
Yes, I built my own plasma table. http://s47.photobucket.com/user/johnplctech/library/Plasma%20Cutter?sort=3page=1 In these videos I didn't have a THC http://www.youtube.com/watch?v=e70jdiDm7yc http://www.youtube.com/watch?v=knf3cPrZPrk http://www.youtube.com/watch?v=3o84BzF90JM http://www.youtube.com/watch?v=qlXCdfPsQUU http://www.youtube.com/watch?v=EC1_TTlsOrM http://www.youtube.com/watch?v=KvhvQu5Xxtk And the latest http://gnipsel.com/shop/plasma/plasma.xhtml I designed the table to be 50 in X and 36 in Y and I can slide a sheet of up to 1/4 thick under the extruded aluminum to cut longer pieces. I usually get my stock in 4' x 4' so the first cuts it sticks out the front or rear some. I did this to save floor space. The last photos show the best water table position.

[Emc-users] Plasma table
Hello! Since I posted lots of questions on this list about the plasma table I was building, I thought that I should share something: http://www.youtube.com/watch?v=OK0hldTjnX0 I took that video with my phone. I was not able to get the servos work correctly, so I ended up with stepper motors, which included also new gearboxes with smaller reduction ratio. I wrote a custom kinematics module for that machine for better THC process - thc offset is added there so that LinuxCNC and user always know the actual joint position. That means that machine soft limits are never exceeded. The thing yet to be solved is the fact that calling MDI commands with gladevcp buttons switch LinuxCNC to joint mode. There are simply gladevcp buttons, linked to halui.mdi-command-nn pins and in INI file I have defined some actions, like G53 G00 X5 Y5 Z100 or G0 X0 Y0. If I use any of these buttons, LinuxCNC will switch to joint mode, once that is completed. Can anyone explain, why is it so and what can I do about it? -- Viesturs If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto -- Everyone hates slow websites. So do we.
