I made a g code 3 different ways and pasted them to note book, using t2 laser, laserburn,and laser grbl after generating g code and putting them on note book... they are not the same, max feed is different for x axis and also my y , axis,,,feed rate is different step 1 laserburn, cartoon cat down loaded ,used trace then exported as dfx, Imported to t2 and generated g code,then copied to note boke then in did it another way < I loaded t2 down loaded same j peg generated g code,copied to not book, and lastly down loaded same cat. in lightburn ,traced and sent to laser grbl,generated g code copyed to note pad 3 different ways, now to run programs in g code lightburn download any of the three g codes it hauls *** !!! down load to universal g code sender and that's when ting come to a crawl , I know laser burn is ment for lasers but All im looking for is x and y and signal to turn something on or off I also have a cnc laser with sainsmart control card, nema 17's now if I run the those 3 on the lase they do the same thing but I can control it the plasma has tb6600 Arduino nema 23 and Arduino, I cn a not calibrate it do tb6600 set to 3 amps 1/8 stepping, NOW do you do the formulary and ad those 2 to grbl so would the be the same , ok who wins scripture for program??? or whats you set grbl for thanks
