Maybe the parallel error over 100mm could be used to provide maybe the hysteresis? With a single ADC input tracking the voltage, you could test cut a piece till you are happy with the height setting (should be about 1/8"), then log and average the voltage (bitcount) and then you have your target for the rest of the cut (need to have a flat piece of metal and a near 100% parallel piece of metal to the x/y gantry or the numbers would vary with any taper over the cut distance. On second thoughts, I guess if you had the bitcount on the one channel, you could set / tune the second channel to the same bitcount using the pot without actually having to cut anything, but then this would be from a stable 5V power supply, still temperature compensation may be an issue, considering there is no way to recalibrate without a hardware adjustment. The negative bit is probably any temperature compensation maybe? Would it not just be better just to log the readings (bit count) for the ADC over a cut say 100mm and then target the bit count for the optimum height? Yup, it's a pot, question is, you need to get a stable torch voltage before you can set the other potentiometer, which I'm guessing would require you to do a long cut at the optimum height and adjust a pot to match the cut voltage. I've got a micro on it's way and 16 bit ADC to breadboard.ĭifferential input, how do you propose setting the differential resistor? The THC drive function above looks like it would be good to employ I was not sure what the loop time would be. I was thinking about putting a calibrate function in there, say running a 200mm cut, with 100mm at the optimum torch height, taking an average set of readings after the 20mm, then dropping torch say 1/2 a mm (1 torch volt apparently) and then taking another set of averaging readings athe the first 20mm for hopefully some torch height voltage, this in turn would give a more exact 1V torch variance, then the anti-dive function could be put in that could be x&y axis travel speed related I've not seen anything that says that this could not be do-able or highly complex. Some examples of specialist posts include machines with multiple heads, say a plasma cutter with a pucnch marking head.That's reassuring, I am trying to keep the component count down (KISS = Keep it simple stupid), less to go wrong (less components to keep the smoke from escaping from).

This service is normally free unless the post is particularly complicated. The programming language used is versatile enough to cope with pretty much anything you could possibly want a machine to do.Ĭustom posts can be written to your specifications. If you so wish you can create your own posts. Unlike many CAM packages the post format is freely available and documented.

These can be fine-tuned to produce code for virtually any machine. To get over this, SheetCam comes with a wide variety of post processors. While G-code is theoretically a standard, most machines have their own dialects. Parts can be placed in an array to quickly fill a sheet with minimum effort. They can be flipped and rotated to make most efficient use of the material. Peck drilling with controllable retract amount Ramp cutting to allow plunging with non center-cutting tools.ĭrill from circles or points in a DXF file SheetCam gives you many options to optimize cutting. Once you have defined you tool you can set up the cut. This increases consumable life and reduces faulty cuts due to blocked or obstructed nozzles
Instead of plunging straight in, the cutter torch can ramp in, reducing the amount of material blown back into the torch. Draw your part the size you want and let SheetCam work out where to run the torch.Īutomatic cut ordering to ensure that inside contours are always cut before outside contours. You can define as many tools as you like for different materials etc. The tool definition allows you define all of the important parameters for cutting. SheetCam combined witn Mach3 and a torch height controller from CandCNC for an unbeatable plasma cutting solution. This is useful for machines running Mach3 for instance.

SheetCam has many useful features for plasma, laser, waterjet and oxy-fuel cutting.įor machines that have full control over the Z axis you can program the pierce height and cut height directly.
