Re: Ideas on growing business

There is no magic solution . A wide belt sander might work but it can also snag a corner and do ugly things to belts and machine. A belt fed drum sander or "stroke" sander would speed things up BUT one thing I found that really made things go faster was to use Muratic acid bath and then wh...

Re: Thermal Dynamics 60i

Sorry had a brain cramp. I was thinking of the TD "A" series (for automation) that has the built in interface. You can buy the interface on later models. When Victor took over R & D went out the window.

Re: kerf issue?

Yes it would be one continuous cut. It going to have to pass through the gap twice,. A closed object has to end at the same place it starts.

Re: Plasma converting to router

You need to design a flat cutting surface with spoil board that covers your water table and have some way to level it if you want to do any cutting that needs controlled depth. You will need to keep the water tray covered unless you want routing debris floating in your tray. Years ago I built a comb...

Re: Thermal Dynamics 60i

The "i" stands for (I think) "Interfacer" . It has the internal voltage divider and CPC connector built in but should work fine with a hand torch for hand cutting. The i sereis do not have all of the automation features/options of the Hypertherm 45Xp thru 125 series but at least ...

Re: Cut definition help please, images included!

Mach3 rounds corners and sharp turns based on the performance of yoor table mechanics. It gives preference of speed over accuracy with CV on. Problem is if you turn CV off and there a bunch of nodes it will start and stop on each one. You need speed to cut the thinner material . The move speed you n...

cant do that. You cannot cross an existing kerf with SheetCAm.

Re: hi new

That makes little sense. A 2D DXF file has no Z plane in it whatsoever. Any Z moves are put in by either SheetCAM Ilike in a touch off sequence) or come from the THC. Typically Z moves are positive (up above zero) . A Plamsa Post only puts in Z moves for touch off. THC Z moves come from the UP DOWN ...

Well, it took some reading but several assumptions I made are false 1. PlanetCNC has their own control software (TNG) that runs in Windows or LINUX.

Re: Post Processor - Planet CNC MK3

The Post is vaguely familiar. It displays its for MACH and the MP1000-THC and not for a Linux based control. LINUXCNC has different G and M codes than MACH. Where did you get that POST? I am surprised it works at all. Part of it will depend on if you are using a THC and if it has an external disable...

You can make it do just about anything you want. If you have the RS485 option you can even have a tool with a 10A current setting.

There are cut charts in the Hypertherm manual that are very helpful. For that thickness, I would use the Fine-cut consumables and follow the book settings.

Then you are SOL. They don't make fine cut or low current tips for that torch .

It has little to do with selling. Is about the use of a registered logo. Whether you sell it, donate it , or give it away you have to have the registered owners permission. It's their property. Giving something away that the owner of the mark makes money on, is to them the loss of a sale (harm). Mak...

Tecmo makes the torch and consumables .

There are no "fine cut " consumables for that torch .

Good luck on finding the actual parts listed somewhere for you to buy.

Re: How to do tool changes with CNC plasma

You can also setup a default tool change action in SHeetCAM that sees a new tool and alwyas does thet action. Options/Job Options/Toolchange. It will stick the code in before each operation where there is a tool change.

Re: New build design specs?

On a rack and pinion machine ( or any other type) you trade Speed for torque....that's what transmissions do. You have rotary torque that converts to linear torque that move the load. Since steppers lose torque with RPM you are always chasing the curve. If you spin them fast and reduce use a transmi...
