Plasma rebuild, new design again

Cleaned out pan and went to a different slat style… It has now been production cutting reliably for a week… No wasted material at all. Very happy with how well it’s working

That slag is impressive.

About 500lbs of it!!

As I can see you have double side plates and the y axis motors horizontal do you gain more rigid setup? Can you share your design files?

I believe it is more rigid, I am using 1.25 tubes on the gantry and NEMA 23s for all but the single x motor… There is a second belt on the other side but that just holds everything together and keeps the little side rollers tight to the tubes so there is no gap for it to track back and forth as it moves along the y axis. I put the motors under because I handle heavy materials, from 16ga to 2" steel plate and have sniped the belts when they were on the side before. And the second y plates is just to get some support next to the wheels and keep the parts from sagging from the extra load and over time and the inside plate is also where I obviously mounter the bearing that ride along the tube. Have u build a v1 machine before? I’d suggest u start there as if there r issues there is a ton of support here. Get on the other hand I’m quite busy and do not have assembly files or time to problem solve. Having said that I would not mind. Pm me if u wish

Are you still using the same plasma cutter? 500lbs of slag, I trust you have an opinion on it. Worth it, overspent, or underspent? That is the largest expense, but there are cheaper and more expensive. I have decision paralysis on that.

I don’t really need a plasma cutter but it sure would be nice to have one and maybe factor it into the next LowRider revision. I am pretty sure I could run some occasional jobs to pay for itself I am surrounded by 4x4 fanatics and they have all sorts of giant steel brackets that would look better off a plasma cnc instead of their oxy torches…

If I remember correctly he strapped an oxy torch to his last build too!

I’m really curious what ideas you’ve cooked up for a plasma specific lowrider?

Yes same plasma, it has worked great really… I will however go to a hypertherm here shortly but I have who know how many hours on this one… Well actually like 70 sets of consumables. More then a couple went to figuring everything out.

DarXide…I just found out who you are.

Holy shit. You bought the very first MPCNC kit I ever made. The very first one. Do you remember how it happened? Did you email asking me to sell it to you, I am pretty sure I had no intentions on selling them but someone emailed and said something like “hey man that is kind of a lot of parts you just want to sell me a kit?”

OMG I am kinda freaking out right now.

PS I don’t go around stalking my users. I shipped Jeffeb3 a box and it happened to be order number 16,000 on shopify. So I had to download my paypal records to find out how many orders I had before I started using shopify… I was looking at the first few transactions, me buying a ramps board, some bearings, a power supply, steppers, then your email popped up! From there I (stalked) searched the user database for the first order email, just to see how long that first guy lasted.

OMG you are still here, you started all of this (I am pretty sure you started it all at least)!!!

In that case, Thank you @darxide!

Yeah, that was some time in early 2015 I think… Had no idea that was the first kit u sent out… That’s cool, I’m sure one way or another u would have done the same thing! I have definitely built a number of your machines…

That’s so cool guys!! And look how far he’s come!!! Both of you! Totally envious of that Plasma CNC! That thing can scoot, too!!!

SO… DarZidE, you should make kits for this!!! :slight_smile: how about that? I’d buy it. You and Ryan can join forces. And I’m sure Ryan wants one (he doesn’t need, he WANTS it - same here BTW!) About how many bucks would I have to invest to get this setup rolling? ballpark it. I’m sure it’s WAY less than my Jeep guy forked out for his!

I would buy a kit too! Hit me up!

That double Y plate idea is brilliant. I will be trying that idea soon to stiffen up my plates.

How do you all convince your spouses to let you have these toys?

Simple. " Oh, if I had a CNC router table I could cut that baby sign for you so easily" and “this stuff on Etsy is ridiculously expensive, I can just make it for you in the CNC” also, " this CNC router would be a good bonding experience for both of us and will help us learn to communicate better"

It probably also helps that we are both engineers :slight_smile: hahaha

Awesome build darxide, looks like you’ve got through a whole lotta cutting with it. I’m built a lowrider as a cnc router and am about to start a separate new build for a plasma cutter. I’ve decided to definitely use linuxcnc and have bought my Mesa board and THCAD and now need to make some table design and hardware decisions.

Any advice on NEMA23 vs 17 or any things you would do differently if starting from scratch?

Yes, next time I’m going to turn grooved wheels on the lathe and use an angle or something to run along to get away from the rubber wheels, nothing has broken or went wrong since my last rebuild though.
