@neilferreri, honestly, probably not an issue with CNCjs. Most likely some sort of hardware glitch.
I’ve been commissioned to produce some oval trays from soft maple. Stock is 32” by 16” by 1 3/4” thick.
Using VCarve pro I’ve designed a couple of trays, pocketed at 1.35”, sidewalls at 1.75, .5 thick.
0.25 2 flute carbide, 0.5” doc, 0.1 step over, 150 ipm - numbers I’ve used with red oak and ash. Never cut soft maple ‘til now.
What happens, initial cut completes, 2nd cut proceeds to 50% or so then machine “stalls” on the X axis and “walks” at a right angle on Y, either + or - Hit the e-stop, re-zero, adjust cut file to start .5” deeper, start again. Same thing happens again, near end of second cut. Fortunately, nothing ruined yet since this is just a giant pocket .
Re-set VCarve file and ran remainder with Carbide Motion 412, finished fine, no glitches.
THEN, set up next cut file, asked CM to home…and… Z and Y did their thing while X vacillated between east and west, not getting anywhere.
I eventually set hard limits to 1, got the machine to home. Turned hard limits off, set up a new tray job in CM, cut fine.
