Does anyone know what causes these little divots at the start/stop point of the plasma arc? The area of concern is at the bottom of the O in the photo. The most obvious cause to me was a...

I recently used my CNC plasma to cut some shapes out of 0.125" aluminum and I have some pretty good warpage going on. Most of what I've done so far is steel, so cutting aluminum is new to me.
...

I feel your pain, man...I went through the same thing before I dove in. After all my research, I decided that for my situation I was going to use a Precision Plasma gantry and CandCNC electronics. ...

Thanks for the replies, guys. The motor definitely turned freely when I had it off the table with no binding. I'm half-retarded when it comes to stepper motors and electronics in general, but now...

One of the support folks at CandCNC told me that despite the horrific noise, the motor cannot be hurt by what I did and to check the motor for loose set screws. While the set screw which clamps the...

I think I've narrowed it down to the stepper motor itself. With the motors locked (power to them), I can grab the end of the gantry where the suspect motor is and move it slightly along the Y-axis. ...

So that would probably keep it from happening, but now that it has happened...I don't know if I hurt the motor or how to quiet things back down. It sounds awful when it starts and stops.

Also, it...

Played around with it a little more, and the noise is only there just as the Y axis starts moving and right before it comes to rest. Maybe just a low RPM issue? Not knowing the cause, I'm afraid to...

It's been a rough night. I'm 98% done with my build, and as I was moving the gantry around I managed to run it into the hard stops. Contrary to what I've heard countless people say, the stepper...

Why wouldn't you just put a piece of CRS or something like that on top of the tubing for the bearings to ride on? That was Precision Plasma's recommendation when building a table for their DIY...

Alright, so I missed the Thanksgiving deadline I set for myself but I did make some progress. Turns out steel is pretty expensive so I had to take it slower than I had hoped. The blood banks in the...

Sure, do you have any specific questions on it, or are you just looking for general feedback and thoughts so far? Keep in mind I just saw it move for the first time last night, so I haven't been...

Appreciate the offer to help, repauli1...but I actually just finished it up over the holiday weekend. I was just over thinking it while designing things in AutoCAD. When it came time to cut the...

Hi Bobby,

Sounds like our builds are going to be very similar, except I opted for ordering a gantry from Precision Plasma rather than try to fab that part up myself. I did this mainly because I...

Finished the cart last week. Hit it with some etching primer and cheap auto parts store paint, will be interested to see how well it holds up.

The BladeRunner will be in this week, and I'll start...

Thanks, CYRAX. It's killing me to be away from the project for this long, but some things can't be avoided, unfortunately. Looking forward to returning home so I can start on the table itself and...

The electronics cart is almost complete, just need to finish up some cosmetic stuff and then paint it. I've learned quite a bit while welding this up, so I'm glad I did the cart first. I'll be away...

I spent a couple days figuring out AutoCAD and drawing up plans for the electronics cart, then went down to pick up the steel once I had all the required dimensions. I blatantly stole someone's idea...

Well today is the day I officially started working on my plasma table build. I've done a ton of reading on this site and others, and I always found it interesting to note how long it took people to...

Thank you! That helps tremendously. Very nicely built table.

What I decided on building is almost identical to yours (minus the etcher), so this will be a great reference, I'm sure.

Cheers,...

Unixadm - Looks like you've not been online here in quite a while, but in case you come back sometime soon, any chance you still have some pics handy of your setup? The link to the pics in the first...

Got it figured out. I was trying to compare the DIY prints provided by Precision Plasma to their fully-built iPlasma tables, but I see now they are different designs.

Also, if anyone has photos of their DIY base for this setup I'd really like to see them. It would help me visualize how the rails are mounted.

Hey guys,

After much research, I believe I have finally decided on what my build is going to consist of. In the interest of going into this knowing exactly what it will cost me, I'm looking for a...

Does anyone use Adobe Illustrator? I happen to already have that, so was hoping it would work. As I understand it, it's pretty much the same thing as CorelDraw...vector based and exports DXF files....

Nacs Fab - I'd really be interested to see photos of your completed setup. I'm brand new here and have spent most of the day reading up on people's DIY tables...yours definitely stands out and I...
