I built my CNC plasma as well, and it also has laser and milling swap-able heads. As such, I have discovered axis acceleration config in the grbl controller to be a huge factor in how smooth the XYZ axes move through corners, cutting smooth curves and straight lines on entrance and exit of corners. ...

That's a great question, I've had the need to do the same at times but have yet to find a tool in SC which edits a segment of a shape that I import via .svg drawing. So what I do in these cases is I use my 2D drawing program (or CAD) to change the shape segment to be defined on a different layer, on...

endZ and most other Predefined Variables described in the Post Documentation are SC "internally" managed variable, meaning they're managed outside the scope of post processors. I don't believe they are intended to be written or changed, but they certainly are intended to be read and refere...

coincidence that I just saw this marking process performed in a demo at FabTech tradeshow in Chicago this week! I'm going to try it soon. So according to your posted pdf, set amps=10 on the power unit, and in SC tool set Pierce Height = 4.6mm, Pierce Delay = 0 (or may need 0.1s), and Cut Height = 4....

yes, if you select any Operation, then all checked Operations will report the cumulative cut distance, pierce count, and run time in the bottom left corner of the main SC window. See the photo.
You can also run a Report to get even more stats on the job.

Les, In the OnPenDown() function of a post script, I'm attempting to use entityClosed SC variable to detect when I'm building gcode for an open shape as defined by the .svg import. That works fine as long as I don't use leadin or leadout on the toolpath. Using either causes every shape to appear as ...

I believe the leadin ramp angle is fixed at 45 deg, Les would have to confirm; 45 deg is the case with tangent and perpendicular leadins. I just tested this by setting up the leadins so they ran horizontally on just the X axis, no Y motion. Its easy to see in a tilted graphic window too. But the coo...

Thank you Les. It was fun ;) I got myself into this ordeal because I love the arc leadin with Z ramp down to cut height. I have a couple of machine torches, one brand being the Tecmo PTM60. Its nozzle and shield design tends not to repel piercing dross as well as Hypertherm's design. As a result I c...

I now have a fix for this problem that allows for the use of G2/G3 without error33 random failures. This applies to CNC plasma process. I discovered that G38.2 probe stmts have a side effect of grbl reading the control point probe position in that the precision of all axes is lost to no better than ...

good idea. thank you.

After a year of plasma cutting with SC, I've recently begun wood routing with it, since most of my CNC routing is contours, pockets, and v-carves. A recent project involved cutting several small odd shaped pockets in a piece of red oak. In order to chamfer the top of the pocket edge, I drew an outsi...

Les, ArcAsMoves() did it! Thanks much. I was looking at that this morn. Here's what I came up with, preserving some feedrate code before and after the arc moves. Or was that necessary to preserve given the ModalNumber() posting of feedrate ? Switching the job gen to ArcAsMoves is much better than fo...

I have a "fix" to this problem. thru trial and error, I noticed the 1st leadin arc began to run fine in grbl after I re-zeroed the Y WCS coord. That was odd, and it just so happened it was on an integer (as in nnn.000mm) machine coord. So I zeroed X on an integer machine coord, that caused...

Hello all. new user. I like SC, gave some considerable study and testing before purchasing. However I've run into a problem, need some advice please. Using SC for plasma process only, importing svg drawings. my CNC is Mill Right brand, running grbl 1.1i on atmega2560 arduino. I modified the SC post ...
