We have a Fadal 5020A CNC88HS. I load programs into the control through RS232. The programs load ok. They show up in the program directory. I can run them all day. After I power the machine down and power up the machine, a newly loaded program might be in the control it might not be. I always use the TA,1 command when I load. I have tried TA,1,2,1 and it makes no difference. Yesterday I loaded 8 programs into the control and ran graphics on all of them. Today none of them was still in memory. Currently there is one program in memory.
There are many old program numbers in the directory (the programs have been deleted). I never figured thjat out either. If a program has been deleted, why is the number still in the directory?
