First, keep in mind that accurate control of torch height is critical to good cut quality as well as to consumable parts life on any CNC Plasma cutting application. Most cnc plasma machines use an arc voltage feedback "torch height control or THC" system that monitors torch to workpiece voltage in order to maintain the correct torch to workpiece distance. This device uses electronics and software to maintain the torch to work distance within +- .005" of the torch manufacturers suggested height during steady state cutting. Generally, if the torch is set too high (too much distance from the workpiece) you can expect excess dross, warpage, and severe cut edge angularity. If set too low, there is a high probability of plate collisions and torch dragging which will affect your cuts, will affect consumable life and could cause torch damage. If you height appears too high....then you should lower the arc voltage pre-set in your software until the torch maintains the correct torch to workpiece distance for the material being cut. If the torch is too low, then you need to increase the arc voltage pre-set. With the Maverick CNC machine the recommended height, voltage, cut speed (and other critical cut parameters) are all stored in the CAM software, simply choose the material and thickness you are cutting, ensure the correct consumables are loaded in the plasma torch, and start your cutting process. Keep in mind that if you change any parameters (such as cut speed or amperage) you will have to reset the pre-set arc voltage. Slower cut speeds will require a higher voltage to maintain the correct physical cut height, faster cut speeds require lower voltage settings. Happy cutting! Jim Colt

does probing use arc voltage sensor? if true, is it necessary to change the post processor on sheetcam?
I getting arc heights problem that is higher than enough height

@@MaverickCNCPlasmaTables my problem is, where do u find the proper volt to begin with related to material being cut?
