I received the “Inductive Sensor Kit” this friday (Great, since it is a long week-end)
The physical implementation was straight forward and the text and video resources were clear. (I use a 30x12 Longmill Shipped October 2020) (Already 1 Year!)
I selected the “Addin-ons category” in the Forum, but some information/question could be also relevant for the “GSender” Category.
I have confirmed that the cabling is OK (Physical Check + $10=19 Check) (Using GSender 0.74)
(With the September 8 GRBL Firmware)
I have followed the Firmware setting shown in text and video resources. (and added Soft Limits)
And homing (to the bottom left) works perfectly for all axies.
However… some questions:
1-While there is an Active Homing Cycle, the only way i found to stop the MOVE was to use the “STOP” Button on the Longboard. Obviously, i know i can hit the “Emergency Stop” Button. And i did. I was surprised that when i Twisted the Emergency button back (to get the CNC Back on) the Homing Cycled continued. I then Pressed the “Emergency Stop” Button again, removed the USB from the Longboard, powered on again, and all was good. Tried the same steps again to see if i could reproduce and i was not able to reproduce (Sorry)
2-Continuing other Experiments, after successful homing, i moved the router in the Center X/ Center Y position and hit the “Emergency Stop” Button. When i powered back on, using the Arrows in GSender to move back to test the X limit (Without Homing). I was not able to reach the X probe. The CNC would not move. I saw in the “Console Screen” - Error 15 / Travel Exceeded. is this tied a “Soft Limit” behavior, since i had not yet re-homed?
3-Continuing other Experiments, after successful homing, i tried the GSender 4 corner buttons.
3A-From the Home position (bottom/Left) if i hit the Button with the arrow pointing Right/Up, The CNC moves in the Y+ Direction, just for half of the possible travel and there is no X+ move. Does this make sense?
3B-From the Home position (bottom/Left) if i hit the Button with the arrow pointing Left/Up, The CNC moves in the Y+ and X+ Directions up to 1" to max X+. Does this make sense?
3C-From the Home position (bottom/Left) if i hit the Button with the arrow pointing Right/Down, The CNC moves in the X+ Direction up to 1" to max X+. Does this make sense?
3D-If i would NOT be Homed, what would these GSender 4 corner buttons behavior be?
I have no GRBL/Limit Switch/Inductive Sensor Experience before this morning, so any insights to what is going on would be helpful. Any help appreciated. I may have overlooked or misunderstood a step… and explaining those mishaps may help others using the Forum.
