Water wicking is a fast problem

We had an employee put a powermax 85 work clamp onto a slat holder on a waterbed. Do some sample cutting on a customers table with finecut and the work clamp wicked the water all the way to the power source. It literally took hours...not weeks, not months but hours. The end of the work clamp had abo...

Re: Trouble with THC voltage

Walter if you want us to service this directly you should let us know. If you are not getting any voltage from the Hypertherm chances are you cable from PWM to hypertherm is bad OR your jack is not plugged in all the way.

Re: JD Squared vs Bulltear 4 x 8

I cannot fathom what drives people to machines with unprotected rails and no wipers or scrapers. There is no way possible in the world of physics that you will not get something on that rail that will dimple it and the wheel in short order. We currently use 5 gothic arch wheels on each side with a s...

Type a number into the box and press enter on your keyboard. On some older Mach's the plug in made the number a negative number. Doesnt matter...it still works well.

Servo Star Lab systems come fully assembled but the side motors are taken off for shipping/crating so they aren't damaged in transit. There is a machined pocket they fit into.

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.

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 ...
