@ Jimcolt,
on 24/10/2017 Hypertherm announces new Duramax torch options for Powermax45 plasma system owners:...
Hi,
Motors get warm/hot anyway, drivers do usualy not.
You set your driver to 4.2 amps while your motor can handle only 3 amps? Either you have your coils in parallel so each coil takes 2.1 amp or...
Maybel welding the two pulleys together is not such a bad idea if you can do it without melting the teeth.
The torgue between the two pulleys is quite large.
I recently added a toothed belt...
I think it is heavy enough, but I am from Europe:rolleyes:
In my opinion the rigidity of your gantry will make the difference; more than the weight or your table frame
You can edit the RefAll button so only the X and Y do a ref and not the Z. I made this change two years ago so I don't remember exacly what I did. Maybe I used a mach screen editor.
I have a hard time imagining you (or myself) staring at 600 IPM with a toggle switch in your hand.
Some of the art stuff I do, does about 300 pierces and 45 minutes of cutting in a piece of 11ga (3...
Any descend prepacked system should support slaved axis.
Configuration in mach3 it is no problem.
Maybe with some cheap chinese sets you could run into problems.
On our local forum I learned...
One motor per axis? You will have to drive your gantry on both sides to prevent raking.
Either with a shaft, belt drive or two motors. On my previous plasma table I had one motor with a driving...
I recommend a Nema 34 on each side of your gantry. You will need some acceleration.
Hi Luis,
I think you concerns are right:
unless your racks are perfectly parallel to the Vrail you may aspect backlash on your pineon. In my opineon you better have the pineon pressed into the rack...
These CS-lab sets look very decent. The manual is very thorough as well, with tips like: "do not use a wireless keyboard".
Sounds like guys with hands-on experience. Poland has a good engeneering...
Steppermotors, drivers, breakoutboards shouldn't be to difficult.
Your location is closer to china than the most of us.
Not plug and play though.
To find a decent THC outside the US might be...
here is my solution for a torch break away.
A piece of steel pipe around the torch (torchbody is not magnatic) is hold in place with a swichable magnet.
Also very useful to detach the torch for...
Here is some support for BBchevy396s argument all the way from Europe.
Before my Powermax45 I had an Italian plasmacutter (the Italians preceded the Chinese in cheap equipment as you know).
I was...
here is my DIY torch break away (concept by WSS).
the magnet is 60 mm high.
the hoseclamp higher up on the torch holds down a microswitch; any movement of 3 mm e-stops the system.
Is also very...
Since reading about all your builds was very helpful I thought I should report back to you on my second build. With an emphasis on some “unusual” details.
The additional specs for this new build...
Out here we have quality differences in stranded wire. I used the one specificaly for moving machinery. Defenitly consider shielded wire if it runs along your plasmatorch cable.
Arthur
that is an original approach for sure. I haven’t seen it before. If you get it rigid enough, with not to much backlash, it might work. If you keep the torch tip some two or three inches away from the...
hi tjb1,
My impression is that users of the machine project log are more mechanicaly oriented, like myself. I have some electronics background, so I can understand your question but not answer it. I...
Here is what I did.
My watertable is 5 inches deep, the slats are 2 inches and level with one end of the table (photo). I can just slide the sheets on from this side. One the other 3 sides I...
I have a heavy T-profile attached to the ceiling, running from beside the table. It extends far enough beside the table that I can lift a plate in its centre of gravity with a cheap chinese hoist and...
Hi Fanefane,
Your machine looks very good. Good thing you invested in the powermax.
IMO you defenitely need a THC (and some ventilation of the shop!)
I looked into the THC-unit you mentioned in...
Hi Fanefane,
Although I am from europe I have serious problems with reading the romanian text. That makes it difficult to comment on that perticular THC unit. If this digital readout in the video...
I agree also on Sheetcam, absolutily fabulous. My technical work runs from Turbocad to Sheetcam to Mach; for my artistic work I use CorelDraw through DXFtools to sheetcam to mach. Most of my time is...
Hi Balestraio,
this torch is probably a Trafimet model:
Plasma cutting torches
Also fitted on the the (italian) Telwin plasma cutters.
Their site has some info on the startpulses.
Regarding...
Fanefane,
My opinion on the Stahlwerk Cut 60: typical chinese entry level cutter. You recognise them from a mile (the casing and the price). The dutycycle is not bad. But look at the video: it...
an original approach for sure.
I am just wondering why you would want to do 5 axis plasma cutting for.
The PM45 wouldn’t cut any thicker than 8 or 10 mm comfortably, so there is not much benefit in...
One more reason I wouldn't use silicon sealants: when you are cleaning out the watertable from this thick mud of plasmadust which collects on the bottom of the table mixed with all sorts of cut-outs...
Hi Rimawi
I already owned a TECHNOLOGY PLASMA 41 230V about 2 years ago when I started the build of my cnc cutting table. It served its perpose as a entry level hand (!) plasma cutter for cutting...
