How are the tables going Dave ?

[dnelso]

Finally after a few weeks of getting nothing done we have movement. motors are running at 1000ipm. Everything looks good so far.Hoping to get these tables finished up in the next couple weeks.

Some pics and vid of old machine cutting 3/16 steel.
Lots of waste

Lots of waste

yeah, can't nrst a part like that too well!

Machines are looking fantastic:cheers:

Finished last of the machining, alum covers for gear reduction box. Fit water tray and welded the two half's. Need to cut the drain in and weld. Still need to get the water tanks and pump. wont be too long and it should be done

Very nice looking table! Ive been a long time lurker but never been able to bite the bullit and start my own machine. Your machine has inspired me though and i hope to start my own build soon. Keep up the good work, cant wait to see more video of it in action!

Thanks
I haven't had much time to do much writing but have tried to keep taking pics of the progress. hope to have more soon.

Dear Dave,

first off, thank you so much for taking all the pictures and documenting your second build. It is just flatout a w e s o m e and for sure it inspires a lot of people to go ahead into the crazy "adventure" of a CNC Plasma Built.

I got stuck at the pont of putting the slats and now seeing your progress makes me wanna pick it up to move on and finish my build.

My question was since I wanna do Routing and Plasma how do I reference the slats correctly in order to do precise routing?

How do you do this? How did you do it?

Best regards from Berlin

Thanks for the kind words. When i use the router i put a piece of plywood over the slats and cut on top of that. Tables are ready for paint then assembly and wiring.

Very nice builds :wee:

any plan to add pneumatic plate maker?

We will be adding plate marker and 4th axis for cutting tubing

Really nice build-

just what i'm looking at doing- just collating the suppliers at the moment, working out best linear rails etc,

think i'll go for the candcnc kit for the electronics looks like a good solution for my 1st one-!

was wondering, it looks like you've geared the steppers on your rack, is it necessary? i'm looking at a router/plasma combo so wanna get the best resolution/ reduce backlash- what ratio did you go for? and did you gear both x and Y axis?

but v nice build you've got-

Both the x and y have 4 to 1 reduction. Its a good trade off for both plasma and routing. Here are some pics of the current state. One table is going together and the other is going to powder coating.

looking ever better-!

i was thinking of using a timing belt type arrangement- was that what you did- hoping it'll stay with a fairly low profile to keep everything neat-

i like how you've kept the sliders/ rack on the sides- i figure that'll help loading sheets on etc- i'm thinking of building roughly as you have but then with a false sacrificaial bed to router on top of- maybe with a vacum hold down- which would seal the dust from the water bed-

did you go for the dragon cut- with the 602 oz steppers from tom?

FYI there's a guy over here knocking these out-

your for £18k or $27k.... how much do you reckon yours has set you back-? i imagine i can get mine done for a quarter of that-!

[dnelso]

George,
Yes i use timing belts. Here is a link to my first build you can see at the bottom of page how the belt reduction works.

worked on keyboard and mouse.
Doesn't seem like a big deal but this was version number 5

It appears that you tapped the tube you used for the table/gantry. What wall thickness did you use? It looks to me that it is 3"x3", but not I'm not sure. I'm hoping to build a 4x8 table using a similar design starting after the 1st of the year.

[dnelso]

The tubing is 3x3 3/16 wall
