Re: help on doing an edge start

Once you do it once youll remember. Nothing special you do in sheetcam other than have your 1st start lead in where the edge of the sheet is. Then simple start the program, see where the torch is, measure the offset from edge of sheet and rezero that offset from your initial x and y zero.

Re: Controlling down pressure

Down pressure is a dance between cylinder size and volume, return spring or return pressure and the weight of the scribing assembly. If you cylinder is too small a single acting cylinder with a return spring wont have enough return spring pressure to lift the assembly If your cylinder is too big it ...

Re: Problems cutting 3/4 with plasma or flame

If you have to sue the 65 you should be going slow. The bottom of the radius will indeed curve inward due to the loss of velocity in the beam and the trailing edge. Its inescapable with the thickness and amperage your cutting. The only thing you can do with that type of cut and that kind of power is...

Re: Those of you who regularly cut 1/2 and thicker stuff...Q.

1/2 is very easy. 1st...loop your corners if you can...where you can. 2nd bring your cut height to .090 minimum (Which is just initial height and not your running height). This will allow you to clear your slag. 3rdly run 65 amps. If you use an air cooled powermax machine cutting 1/2 at 65 amps will...

Re: Combination Router/Plasma Tables

The most common way our customers will do it is cover the waterbed with poly and use a subplate. The subplate will sit or be clamped to the slat holders that are welded to the bottom of the water bed. Then they screw or clamp the material on the subplate.

Re: Pronest for Ethercut

Pronest does include consumable amperages and material sheets. It does not support direct current control as offered by CandCNC. Sheetcam however does support that feature as well as array.

Re: How to fix rounded inside corners

That problem your seeing may be in the way your drawing carries over to sheetcam. Make sure the radius is not carrying over. We recently had this issue with Designtofab cutting production duct work with a HVAC company where the D2F would output the last inside corner as a radius instead of a square ...

If you take the green wire out of the equation you should be able to use your floating switch but the ohmic will have to be powered off for it to work properly with a switch offset.

Re: Thermal Dynamics Cutmaster 152

Sometimes the consumables and retaining parts of the TD torches come new with bad threads that kick out the working parts of the torch to the side. :geek: Take your torch out and take a good hard look at the working end. Should be pretty obvious if its the torch or not.

Re: How shallow could a water table be and how far from the metal?

We have a customer that cut 1/2" material for 6 years on a 3" deep water bed with a 200 amp plasma. Deeper than that for less amperage means wet hands and shirt cuffs and really adds nothing but a deeper pool to pick your parts from.

Re: Where no finger should go.

That is the benefit of being burned by plasma...instant cauterization. We had a customer that hand a hand cutter on a 150 amp plasma that blew out the back and put a nice hole in his hand. It just proves that we must be extremely cautious working around these powerful pieces of equipment.
