I used the standard 4x8 precision plasma gantry kit and welded up the table pretty much according to the drawings provided by PP.

I have almost exactly $10k in my table for everything needed. I built the table myself, purchased the gantry kit from Precision Plasma, the bladerunner kit from candcnc along with the Mach &...

I cut a lot of aluminum on my table. Everywhere the cut crosses a slat that is in contact with the slat leaves a chunk of dross right there on the part. I could foresee the points causing problems...

Quick, cheap, easy, and it doesn't require the gantry to have to drag around all of the extra weight of a wire...

I do understand the physics and motion involved. My gantry is nearly 5' long. Unless there have some developments in materials that I'm unaware of, it is still impossible to make my gantry...

As I Lean said, and what I posted earlier.....I'm also wondering if having the velocity set at 150 in you motor tuning in Mach.......and then running a file with 320 as the speed in sheetcam is not...

Thanks Tom! I do have a hypertherm 85, and for thicker material, the numbers out of the ht manual work pretty well. The problem I have is running pretty much anything over 200ipm. Thinner sheet...

I've just been using plain old Arm & Hammer WASHING soday from Walmart. I've had this in my table since April and I have not enough rust to talk about. There are a few places on my bare slats that...

I think all of the drawings can be found at the precision plasma website. If not, you can contact Ron thru that website and he can point you in the right direction. Still running the table on a...

Am I misunderstanding, or are you saying that you have your velocity setting in your tuning set to 199, but you are trying to cut at 320? I'm wondering if that is not your problem? It also seems...

No idea why you volts are off, but why not just put 103v into your THC setting? That's pretty much how I set up the THC voltage for all of my different materials......run a piece with THC turned...

Thanks guys. How many of you guys have run your tables in sub-freezing temps? I've got a couple of concerns.....one being issues with the motors or electronics.....and two being the fact that I can...

Well it's getting to be that time of year. Been running my plasma/water table since spring running with just water and washing soda......zero problems and very, very little rust. I have my table...

I didn't have any luck with the spring-loaded tension on the motors/pinions. The pinion always wants to walk back & forth on the rack. I ended up setting the rack-to-pinion fit by hand and locking...

I purchased a Fine cut kit with my P-max 85 with machine torch, and was going to use it but I opened it to find that they sent the shield for ohmic sensing, instead of the regular fine-cut machine...

Thanks Dustin. That's good to hear. With zero experience with any of this, I had no idea how much I could play with the speeds and what the benefits or consequences would be......and what other...

Thanks a ton for the reply Jim! I do have the machine torch and the machine torch shield installed. I also do have dthc running with all of the speeds, pierce height & delay, cut height and arc...

Well, I've just got my plasma cutter up and running. It's a 4x8 table, gantry kit from Precision Plasma and Bladerunner/Dragoncut 300-4 system from CandCnc. Using SheetCam and Mach3. Hypertherm...

Finally worked up the courage to push the "Run" button.

Well, I've gotten this far:

I want to give a HUGE thanks to BBchevy for taking the time out of his day to help me thru some of the set-up of my table! Getting closer every day to lighting the fire on this thing!.....now I just...

I'll love it better when it's cutting metal! Thanks for all of the help so far BB! And thanks to you, Jeremy, for answering all of my questions on the plasma cutter. Hoping to get the electrical...

LOL!!! I'm sure I have a lot more of those moments to come!

Doh! Thanks! That would have saved me some time. I did get everything figured out finally. Not exactly sure what happened the first time when I changed the number in the "Steps Per" box....but...

Hey BB....I don't suppose you have any pics of how you hooked up the THC card or where you have your card mounted? I'm to that point on my build right now, and all CandCnC has in their manual is...

Am I changing the setting in the motor tuning part where it says "steps per". Right now it is set at 5300......I tried changing it to a lower number and it reversed the direction the gantry...

Ok....I'm to the point where I've got everything hooked up and the motors all driving in the proper direction in Mach. What I can't figure out is how to get them to move the correct distance. In...

Thanks guys! That helps me a ton!

Yes, that does help! I guess my issue with squareness is that without the stepper motors installed, I have the gantry/rollers adjusted so it is square, and that's the way it wants to be....but with...

I'm working away at my 4x8 plasma table using Precision Plasma gantry kit and CandCnc Bladerunner controls with Mach. Do I need Home/overtravel limit switches at each end of both my Y and X axis? ...
