@@yoti-fabI looked into this, but By time I purchased the coils it was as much as buying one. Maybe DIY coils would be an option, but after my years working in a motor shop, that is no small task.
Good informative video. I am in the process of upgrading or rebuilding the DIY table I started in the summer of 2017. Your video reminded me of many of the decisions I made building it over the years and what changes I could make to improve the cut quality. Thanks for making it.
I agree, but I have never had a problem with the software limits maintaining the position. I think they are becoming less important, buy a backup system never hurts.
I had the langmuir table for a bit without limit switches, but quickly bought the upgrade kit when they came out. I am pretty careful with things, but "crashing" the table will happen and I cringed every time!!
I bought a Lidl Parkside plasma cutter with integrated air compressor for £149 that fitted a cheap purpose -built CNC kit that cost me £150 from a Turkish eBay seller. Paying only £300 for the two, meant I could afford a decent water cutting table and filtered fume hood, for less than a typical cost of a pre-assembled CNC plasma cutter.
I found a red box movie machine from Walmart. Lol take the door off. And there sits a CNC machine lol. Lol you just have to pic right movie 🎥 to get the right cut lol. And you can move it to your freinds house . To borrow lol. And it hold water 💦 in the movie slots. Lol crazy. Strong . Wish I could just reprogram lol it’s there 😮 or new flash on program ??
The accuracy debate on these machines is amusing. It's a plasma cutter, not a 3d printer or a laser cutter. Fancy ballscrews and linear rails are overkill for something like this.
Linear rails and balls screws keep the cuts much cleaner and less chatter on the edges than belts that stretch and rebound. ........ My diy uses linear rails and 10mm belt and cuts OK. it's been totally acceptable for what I do with it.
@@rebelengineering agreed. It does seem to work pretty good but I just recently ordered a 15mm belt (2mm pitch) and 20 tooth drive pulleys from AliExpress for an upgrade. It just arrived yesterday. Should be interesting to see if it makes a difference....... (My current setup is 10mm belt, 10 tooth pulleys, with 5mm pitch.)

This is a video worth watching for anyone building a DIY table. I overcame many of the same hurdles with my build. Nice work!
Thanks!!! Feedback helps me know what to make more of.
How about an electromagnetic break?

Thanks for watching. I'll have to come up with some more unique projects.
Another nice video keep continu your good work!
Thanks so much! I appreciate the encouragement!
The benefit of linit switces is if there is a problem u can restart your cut still cause the machine nows its cordinates

U dont have to weld that rack industrial machines arent welded it just needs to hold the gear pitch so the gesr can travel across it
Possibly, but the guy who designed and sold me the gantry kit told me to weld it, so I did.

If it works, awesome!
@@rebelengineering Where there's a will there's a way! 👍😉

If it has stepper motors, just replace the controller. It would probably make a good 3D printer.
Awesome 🙂
Thanks so much. Means a lot and inspires me to make more.

Agreed. The low cost of linear rails right now does make it appealing, but definitely not a necessity.

@@toddmayta7615 10mm is a pretty small belt. I have a 15mm belt on my co2 laser cutter and it has a very light head.

I like "experts" that criticize peoples' choices in the machine that they are building. There is no set rule for every option of running.
You sound like a guy that actually built his own table
Yes I did!
