can you have more thant 1 grbl on you desk top and not opened!!! I don't think so, I have 1 laser grbl 2 lightburn 3 t2 laser 4 easel 5 source rabbit 6 universal g code sender today I was jogging in laser grbl adjusted the steps from ten to 1 and feed 250 to 125 and left it that way,for chinees lasere cnc 2 hours later I went to the garage to use plasma cuttere and opened ugs for plasma tried to (g0x5} and it went 1 inch ?? I thought jogging don't affect the normal stuff, went back to laser grbl switched back the setting, then went back to usg , hit g0x5 and it went 5 real fast, now I tried to do a three inch squar in usg and it went 400mm in pos ?? but did the squar, I thought if you go x5 it will only go five inches so it should have stayed within parameter ?? thanks robert again why would changing one parameter in one program and effect the other? should I have only one on my laptop for sending
