I'm using a 24ga cat 5E shielded for the control cables on my clearpath servos. The power cables (72volt) will be a 14/16 ga. Not sure of your specific devices,but they should have a PDF online at their site that breaks it all down.
Your VFD - spindle wiring should be shielded 4 core cable about 14 ga. The shield should earthed at the VFD end only. Also check that the earth pin on the spindle is connected to the body of the spindle. There are some spindles out there that are not earthed correctly.
When you setup axis in MASSO you provide the length of each axis, this creates soft limits that MASSO uses to calculate whether the commanded move will result in an excursion beyond the physical limits of your machine. But you can still run the machine past these limits if you have F3 in continuous jog mode, so hard limit switches will force you to re-home the machine if they are tripped.
I have limit switches on both ends of X&Y axis because I was homing the machine to the right back corner and setting X0 & Y0 to the left front corner, but have since changed homing to LF corner. I find using MDI quicker to move about the table than jog buttons/keys, so if I command a move that exceeds the soft limits an alarm is thrown and there is NO movement. A valid command resets the soft limit alarm. I haven't hit the hard limits since.
Great video, it helps a lot. I did a spring loaded over shot so my switches would not get totaled by a 350 LB gantry not stopping on a dime. I think a proximity type switch would probably be better suited for the operation but these are mounted so we will give them a shot (pun intended)
Thanks for the great video it made setting up homing and soft limits easy, however when I went to set up hard limits I see no drop down on the menu stating " X,Y or Z Hard Limit". This is the same with or without the toggle "disable hard limit" in general settings checked or unchecked. What am I not seeing here?
