Greetings all; Working on my gcode to make it run better on this new machine, as part of the init code, I have a G10 L2 R0.00000 to cancel anything left in memory, then 5 or 6 lines later running in map G54, I have a G10 L2 P1 R-90.000 to rotate the whole pattern so the long side is aligned with the tables T slots to aid in my aligning the workpiece on the table.
I've also rewrote it so the dsub connectors are located by offsets that are added to all the x/y locations, so the connectors are shown in the backplot at exactly where they were before. But the backplot is not showing the effects of the G10 L2 R-90.00000, the pattern is still laid out horizontally on screen. The machine, when I go to it seems to responds to the mdi commands, rotating the red/green arrows as requested. And a move command is in the expected direction, but the arrow keys are still x=horizontal and y=to/from. So I'll figure it out eventually. On another front. I opened up the OEM motor box, finding its supplies for the stepper drivers were only about 14.5 volts, disconnected them all, AND much more importantly to me, the vfd circuit board does indeed have a well marked REV input that wasn't used. AVI which I have to assume stands for Analog Voltage In, com, fwd, and reverse, so I whittled off about 6 feet of cable and connected it. But I see both a 10 volt and a 12 volt called out but not used, so I've not a clue if the AVI is 5 volt or 10 volt. Aha, might have found it, register setting D031 0=digital, 1=AVI, 2=ACI(0-20 ma) 3=485 com port, 4=PWM, and 5=potentiometer(front panel?, doesn't say.) So now I have to find me a terminal block. I have a gs16-4 connector on the back panel of this home brewed driver, but apparently no record of which pin is which. I coulda/shoulda left notes in the hal file. I can scope or meter it, just have to get the scope 7 feet up in the air But I was getting light headed from all that running up and down a short ladder, so figured I'd better come in and check my sugar, which was fine at 135 (great for me) but the blood pressure gizmo says my systolic pressure was about 20 high at 141, but the pulse is only 41. Half or less what I've been for 83 years. Might be time for a different BP pill. This lashup was hard put to run the HF mill at 20 ipm rapids, but with these motors and slightly faster screws, X&Y are happy as clams at 60 ipm, and Z is doing 80 without any complaints. Software stepping mind you. I also levered it back on the table until the back of the Y screw is about to touch the water tank, so the spindle motor can't destroy the next monitor shelf I make. Progress, I think. Dinner time anyway.
