Big 1" Cut Job On My CrossFire CNC ! - Langmuir Systems and Hypertherm 85 for the Win !

This was an emergency repair job on a wood pellet mill. The inner circles were a critical dimension, so I cut them nice and slow. I used old consumables and and 3.5 second pierce delays for all 7 pierces, then I switched to fresh consumables for the cuts.
Just saying, this amount of weight on the Langmuir Systems table is pushing it...lol.

[@bretthays2674]

The first video of yours to pop up on my feed was your new water table after burning through the factory one. I was thinking ‘how on earth did that happen’ then I see this video and it all makes sense. Lol. Great work.

[@mrmidnight32]

What’s more impressive is the fact these tables don’t buckle with all of that weight lol I was expecting to cut 1/2” until I assembled my pro and said there is no way this is going to handle a sheet that heavy. Well you proved me wrong haha

[@joshuazimmerman8631]

My Crossfire Pro still works hard everyday... Impressive machines for the money...

[@joewhitney4097]

Wow, great work for that small of a table. Pretty good quality cuts for the thickness. Thanks for sharing.

[@HoodWeldingandFabrication]

Great video! Awesome seeing it installed and doing what it is meant to do! I’m about to purchase one of these tables. It looks to be money well spent.

[@airgunningyup]

that piece of plate steel must have been a fortune , nice work

[@hotwheelsbigwheel916]

Impressive cutting results!

[@easttexasengineering3489]

Very impressed brother

[@justdoingmyownthing.2504]

Great video, my question is where is the video of you getting that 1" thick steel on the table ;)

[@joshuazimmerman8631]

I had two other people help me lift it up...😁

[@OfficialNetDevil]

All’s I can say is damn! Nice job man!

[@First_Class_Amateur]

You are my hero.

[@akusitaaiai2215]

Joshua show us what air compressor do you have, what air filters you are using please! What is your setup? I’m pretty amazed by cutting quality man!

[@PoleLowe]

I am also interested in your compressor and dryer set up! How much cost does that add to the price of admission?

[@Flipping_Assets]

That's some thick ass metal

[@johndunn9819]

nice. how do the pierces go?

[@christianscustoms6429]

Awesome! Thanks for sharing.

[@phillhuddleston9445]

It looks like this machine with only one drive motor on the Y axis and the torch arm hanging in the air is well suited for slow cuts on thick material, I would not think it would be great on fast cuts on thinner material though, am I wrong?

[@joshuazimmerman8631]

The machine in the video is the original CrossFire. We have since upgraded to the CrossFire Pro, which has the rail supported on both ends. The original machine performed excellent across a wide range of speeds. It was important to keep grit and dirt off the rails so that there would be minimal bounce as the bearings traveled over those surfaces. Speeds in excess of 250 inches per minute were not a problem. The open-ended gantry made it easy to work with large sheets of steel, something I still sometimes miss on the Pro...

[@dreexnyc]

I have the powermax 45xp I'm not sure how to connect to the crossfire. I dont want to open the side panel and plice into the wiring is there an adapoter that I can buy to go into the port of the back of the machine ?

[@joshuazimmerman8631]

Yes, Hypertherm makes a CPC cable which is what I used to connect the Langmuir torch fire wires to my Hypertherm 85.

[@dreexnyc]

Thanks so much for the information

[@rodswim492]

Nice job for the money!

[@minskmade]

to awesome making a 4x4 plasma cnc now....

[@tomondulich8113]

great video. how did you not get a bevel on material that thick. the thicker the material the more pronounced the bevel gets. any suggestions?

[@joshuazimmerman8631]

In my experience, bevels aren't caused by thick material. They are often a result of worn consumables, moisture in your air supply, or incorrect cut speeds. Probably the worst bevels I have experienced were on quarter-inch material.

[@johnlocke9609]

Your compressor has to be a 80 gallon 11cfm one right? Because that was a lot of continued air.

[@joshuazimmerman8631]

It's actually a 120 gallon, twin 7.5HP pumps. It's the main shop air supply... Not just for my plasma table. 😁

[@johnlocke9609]

@@joshuazimmerman8631 thank you for your reply, I may need to change my 4 gallon DeWalt haha! I have the Everlast 80s. But not a good compressor. By the way is a GREAT job what you did there. Cheers!

[@OfficialNetDevil]

You got a Facebook Page? I need your help. Would you be willing to share how you connect the wiring kit to the 85? I got everything else together and stuck on this lol.

[@jonbozzy9600]

What plasma cutter are you using? Did you drill the holes in the bottom or did the plasma cutter do them? Thanks.

[@joshuazimmerman8631]

I am using a Hypertherm 85. All the holes were made by piercing with the plasma.

[@johnw4590]

How did you pre pierce the steel plate for the holes? And did you change the 85 consumables afterwards to make the final cuts?

[@joshuazimmerman8631]

I ran the program with old consumables first to pierce all the places and then I put in new consumables and re-ran the program with almost no pierce delay since the holes were already there. Probably a MAG drill would be a better idea if you knew exactly every place it was going to pierce.... But typically I have old consumables laying around that work pretty well as sacrificial items for this type of job.

[@johnw4590]

@@joshuazimmerman8631 Thanks! I guess you can program the torch to stop after piercing?

[@joshuazimmerman8631]

@@johnw4590 I would just manually pause the program, clean the dross off the top, and then resume the program at the next pierce point.

[@steveu235]

can you use the hypertherm 85 with 220v

[@joshuazimmerman8631]

Yes, it's the largest plasma available for 240v single phase.

[@ShreddinSleds]

Fuck yeah dude! I’ve been wondering about doing 1”. How much weight can that table support?

[@russellseawright6412]

How did set it up just to pierce the holes thanks

[@joshuazimmerman8631]

I ran the program twice. The first time around, I let it pierce the hole, then pressed F5 to stop the torch and space bar to pause the program while I cleaned up the slag from piercing each hole. The second time around, I had fresh consumables and just ran the program like normal.

[@russellseawright6412]

So you unpause let it finish the hole with torch off and turn back for the next pierce and repeat sorry for all the questions never ran anything cnc before thanks

[@joshuazimmerman8631]

@@russellseawright6412 Yes,... I hit F5 which extinguishes the plasma arc, then I hit the space bar, which pauses the program. This gives me time to clean the slag from the top of the work piece. Piercing 1 inch steel puts quite a lot of slag on the top which can actually snag your torch. After I'm done cleaning around that hole, I press start again so that it goes to the next one.

[@steveriley1600]

Joshua Zimmerman what was your height set too.

[@sallongdj]

Awsome cuts...What software do u use?

[@joshuazimmerman8631]

I use Autodesk Fusion 360 for CAD and toolpath (g code) generation, and then Mach 3 on the cutting table to run the G code and cut the part...

[@Kri5A]

what is the cutting surface of the table?

[@joshuazimmerman8631]

The max dimension that I can cut is 25-1/4" by 33-1/4”...

[@duramaxmak]

What was your total cut time on this pieces

[@joshuazimmerman8631]

The total cut time according to the Fusion 360 simulation is 12 minutes 31 seconds. Actual time would have been a little bit longer because I spent more time on my pierces...

[@ramonlozano586]

What plasma cutter you using

[@joshuazimmerman8631]

Hypertherm 85 with a mini machine torch...

[@Welder6131]

Did you pre pierce by hand?

[@joshuazimmerman8631]

No, I pierced with the CNC. I just ran all the pierces first so that I could clean the slag off the top of material before I cut the whole piece...

[@jeffheld3971]

What plasma cutter do you use?

Hypertherm 85

[@AlessioSangalli]

@@joshuazimmerman8631 damn that's three times the cost of the table 😅😅

[@ShopJock]

How do you like the table? It looks to be holding up pretty well and with some heavy cutting projects. Im debating getting into a cnc table and this one looks like a good entry level one.

[@joshuazimmerman8631]

I like my table quite a lot! It has handled everything I've thrown at it. I do have heavy duty casters on it and a deeper water table...
