I have a scriber installed on my DIY Cnc Plasma machine on the Z axis next to the plasma torch. The Scriber is located on a linear guide and is driven by a pneumatic cylinder.
In the post processor, I changed the way it works so that the Scribe solenoid is activated (M8) at the beginning of the Plate marker operation and deactivated with M9 at the end of this operation. There is no unnecessary raising (M9) and lowering (M8) of the scriber during this operation. I also managed to insert the variables "Scribe Plunge Speed" and "Scribe Plunge Distance" into the post processor. Scriber now descends from the SafeZ position to the "Scribe Plunge Distance" by a rapid movement (G00) and continues into the material with the movements of the "Scribe Plunge Speed" G01. This way, the Tig tungsten I use for engraving stays sharp longer and the engraved lines look better.
I need help with the following:
For scribe operations I have added referencing independent of plasma tools. Also for Scribe the “touch off sequence” happens exactly where the next plate marker segment begins.
I added a variable to the post processor:
post.DefineCustomOption ("Scribe Ref Distance", "ScribeRef", sc.unitLINEAR, 0, 10000)
Code: Select all
function OnPenDown ()
if (toolClass == "MarkerTool" or tool> 99) then
if (dist> = "ScribeRef") then
dist = 0
References ();
end
