Perhaps, I should ask this on the another forum, but I know you guys are very helpful and friendly. As I work on my power supply issues, I've been playing with the LinuxCNC GUI. Note that my motors are wired, but are sitting on my bench pending the ball screw, nut, bearings, mounts, etc installation.
First, I have a Emergency Stop button wired to the BoB and configured in stepconf. When playing with the manual controls, I notice that the emergency stop function doesn't get recognized immediately. For instance, if I'm doing a continuous X-axis movement and hit the switch, nothing happens until I reverse direction. I would have thought that the stop button would have instant affect and shutdown all movement. It doesn't as far as I can tell. I'm hoping when running a G-code program, it would have an immediate affect, but I don't have any code yet to try.
Second, I plan on using the mill in manual mode a lot for simple things. The Axis GUI in the Manual Control tab and DRO tab allow for setting the Home positions. This is great since it will not allow the position to get out of bounds and damage anything. After setting the Home positions, I would like to be able to move the X, Y, and Z positions using another reference and zero that out. For instance, I could set the edge of the part after setting home. Or, I could set the beginning of the cut as another zero. Is there a way to do this?
Third, I'm thinking what to use as my home position. I'm thinking the centered position for my X-axis so that the range is about -10" to + 10". For Y-axis, I'm thinking of using the front of the cross slide vertically aligned with the base so that the range from there would be about -2.5" to 4.5". For Z-axis, use the middle position giving a range of -5" to +5". Does this make sense?
Fourth, I'm assuming Touch Off is used to reference a position on the part for the G-code. For example, I'm thinking I would use Fusion 360 or FreeCAD to reference the back left corner of the part as the G-code origin. Then, I would use and edge finder to find the left and back edges of the part and use Touch Off. I think that's what the offset GUI that pops up is for? The edge finder has a 0.100" radius, so I would enter that in the GUI? Plus or minus? For the Z-axis, I would lower the tool until it just touches the part and then press Touch Off without an offset?
Thanks!!!
