Re: The AcornSix CNC controller kit has been released!

Since closed loop with digital scales works can we home to scale Z pulse?. If not, can we home to home switch and move back to closest Z pulse?

Re: Lathe ATC Easier Macro?

Steve, Attached is the cnctch.mac file for the indexer tool change that I am using. Air solenoid is on input 2. The 4 second pause could be shortened. I set it to 4 seconds for testing after air system reconfigure for testing. Not using the internal switch for homing I just leave it at tool 1 positi...

Re: Servo motor as lathe spindle motor

Hmmm, I would quote some the comments here, but I think they are all valid, albeit in different ways. Based on this discussion I will leave things as they stand with an encoder on the spindle and a 3 phase motor and VFD to drive the spindle. I can change / experiment with the servo as a spindle mot...

Re: Servo motor as lathe spindle motor

Looks like a Grizzly lathe. Just cnc'd a G4002 used a Hitachi VFD, Leeson 2HP motor, RLS encoder. Considered using a AC servo but the VFD & 3 phase motor seemed easier. I also have a mill that is ready to be converted to Acorn from Mach 3. Been using a AB AC servo (think it is 1.8HP) as the spin...

Re: Lathe ATC Easier Macro?

Got it working. Had to remove the lines on cnctch.mac G53 A[#102 + 0.5] G53 A[#102 - 0.5] and replace with IF #4120 == 1 THEN G53 A0 IF #4120 == 2 THEN G53 A45 IF #4120 == 3 THEN G53 A90 IF #4120 == 4 THEN G53 A135 IF #4120 == 5 THEN G53 A180 IF #4120 == 6 THEN G53 A225 IF #4120 == 7 THEN G53 A270 I...

Re: Lathe ATC Easier Macro?

Marty, The ATC is the Dave Decaussin built that I bought from you on ebay. Been using it without problems manually inputting MDI commands to index and change tool number. Don't have the sensor wired in yet but likely will not use it as it trips between tools and is not on when a tool is in position....

Lathe ATC Easier Macro?

I have a 8 position ATC that I have set up and working moving to all positions using MDI commands Axxx where x = tool number X45. I down loaded the latest macros for axis driven cnctch.mac, mfunc21.mac, etc. The macros do not work with my setup because I have a 3rd axis (A) set up as rotary and turn...
