Yes, it is absolutely magical the true operant power of Christ. You’re beautiful imagination at work thank you Serra for taking the time to put this video together. If you could please put a video showing all the steps you took to make this that would be greatly appreciated. Blessings.
This is the very first video I see from you. I would like to command you for putting together such good and informative teaching. And thank you for sharing. I also appreciate no music and other nonsense that so many wannabees do on RU-vid. Subbed!
Love the machine first video! one suggestion the box section that holdup the gantry... weld a plate on the inside.. I know its rigid but I believe it would also induce resonance ... I am learing from other peoples mistakes 😉 and stealing as much as I can with my eyes
Very nice, opens up doing thin stock with a good cut. The spring loaded pinion is a nice idea, effectively wear compensating while maintaining consistent engagement.
Hi Rob just an update on my machine, iv had the y x and z running on the table put a marker pen to scratch out the drawing and I’m really happy with how things are turning out, thanks so much for your help and the planetary gearboxes are amazing the big beam is brilliant and not to big or heavy
Hey Rob, I always learn a ton of stuff from each of your videos, so thanks for continuing to put them out. I never get tired of watching people's plasma tables in action and I thought I liked the sound of my direct drive ballscrews, but your closed loop stepper motors do make a sweet sound!! With rapids approaching 20m/min, have you considered an anti-collision mount 'thingie' for your machine torch?? PS. Enjoy your holiday.
Hey Rusty Thank you. Next video will be testing magnetic anti collision. Still figuring it out as I only really want to use one sensor. It would make interfacing to Myplasm easy. You planning any upgrades to yours?
@@robbroomfield468 I have a machine torch for mine so I'll have to make a holder for it. I've also bought a bigger electrical cabinet so a rewire job is on the cards soon. I have been thinking about building a bigger table, but to date, I've managed ok with my 'half sized table'....it's getting sheets of steel loaded that is something I'm working on 'in my head'. Probably go with an overhead gantry style of crane. Another upgrade I'm working on now is improving the reliability of my ohmic sensor...it works fine until water splashes on it, so I'm looking at a low pressure air purge to keep the water away from the sensor.
@@RustysMetalCutSignsDesigns I am currently in the process of Building my machine and plan to do the ohmic just like you, using the torch standoff. What I found is a guy using a potentiometer in the wire from the ohmic sensing. With that you can adjust to a point, where the torch is going to detect the Metal but splashing water does not affect it. I am going to Try it this way Cheers
@@SIickDaddy I tried a potentiometer in series with the ohmic sensor but it didn't help that much. The issue I have is water gets 'trapped' between the torch tip and the inside edge of my ohmic sensor, so it's more of a design problem...something I'm working on.
Maybe an air line to auto blow the water off. Connect it to the arc off and stick a delay on it, so that it blows for say 35sec. Just an easy idea. I'm lucky as I have a Hypertherm 105 that sorta does that for me.
I ran perfectly well for 3 years with standard open loop motors and drives but I felt to be more pro it needed closed loop and it has massively improved performance and they are cheap 😆
Cheers Rob Yea i hear you on price but My question is do you need to use a different or certain motor driver to get the closed loop system to work with the existing myplasm control board? Im planning a build atm and want to use myplasm but cant find any info if myplasm supports closed loop stepper motors and how to go about it and your video has shed some light on the topic thanks. Any chance you can post a link to the drivers you used?@@robbroomfield468
Sorry yes. No problem. Myplasm functions exactly the same. It's the motor driver that takes care of the closed loop not myplasm. You wire it exactly the same. Hope this helps. R
Hi, very impressive, I have never seen a CNC machine move as quick! 🙂 Trying to build something similar myself, so glad to learn from your experience and will be incorporating the 10:1 gearboxes. Just wondered what motors you used, they look like NEMA 34 3NM ones from the video, although the label on top is a bit hard to read.
Hey man, very nice set up, I am very impressed. I have to question for you, which software do you use to generate the rotary axes CAM files? I love your clamp idea attached to X axe. Could you share the design? Thanks again, One of the best plasma cnc that I've seen
Hey Thanks. I use sheetcam rotary plugin to get the size, then export the template it generates to a dxf, then QCAD to import dxf and then draw/design part, back into sheetcam to post process and on to Mplasm. By 'clamp idea..' what do you mean? I can get the design files uploaded once I know what you are after. Rob
The gearboxes seem like a cool idea but would this be a poor idea on a combination plasma / routermill tool? I seem to recall the higher rpms of the motor would result in less torque?
Hi Thanks for the sub. That's is sort of true however, the gearbox more than regains that torque because of the 20:1 reduction ratio. Hope this helps. This machine will not think twice about booting you out the way as though you are not there! Lol
Hi Rob great upgrade. With your pipe motor how did you wire it up as there is 4 point on myplasm but you have 5 motors. Do you swap them over ? Thanks Dave
hi David Both Y axis motors are on the same output. Therefore Y one motor, X one motor, Z one motor and finally the A one motor (outputs) this config has never caused me any problems to date. hope this helps. Many thanks for the sub and question. Cheers
@@robbroomfield468 Thanks you for your reply, that makes sense, i have watched all your video and Rustys Video on how to build a plasma CNC, Thanks Dave
Hey rob, Looks like a good upgrade, i tried to read your parameter settings in the myplasm screen. I'm currently building a simular table with myplasm and 45A jasic cut. Do you mind sharing some parameters? It is very hard to start from scratch i noticed. Greetz from Holland
Hi Here are my complete settings. Unpack the zip and you will see the individual files that you can extract into your myplasm directory. www.dropbox.com/t/K6CqIKx0rZgfggzy
Thank you so much!!! Good to know there are still people doing thing in de act of kindness, saves me months of trail and error! Wish you a fortunate future from the netherlands :)
good to see someone who is effort to upgrade his machine for better results. im currently upgrading the mine using myplasm. "EXCELLENT" plasma control software im gonna show you the mine when is ready. 🤪
Hi like your build and looking through RU-vid for ideas I see your Y axis is VEVOR Linear Guide Rail they look like a good way to do this espeshaly considering the cost of Hiwin linear they seam ridiculously expensive. And can you pm me any details for the motors and gears I would love your help 🙏🏻🙏🏻 I’m in North Wales
What dimension pinion gears do you use? Are they keyed or regular ones with two stop screws? If they are with stop screws, did you just install them on the gearbox without the key (stop screw in key slot)?
Hi Rob my build is coming along good and have mounted the cross x rail now it’s a 100x200mm box if not the same as yours only criticism iv had is that the x is to heavy for nema 23 and should be using nema 34 but from your videos it seamed to be better and stronger than any one els out there. Just wonders what’s your thoughts obviously yours is running as smooth as can be It’s all very confusing sometimes
@@robbroomfield468 I’ve got 1.5MODS On mine. I’ll be building my new table based of yours over the next week now everything thing has started to arrive. So fingers crossed I have no hiccups.
