I’m building a 90w laser, based around the popular ‘Further Fabrications’ design with a Ruida RDC6445G.
I installed Home and Limit switches on all three axes, which did work fine. But now, the Y axis limits are showing as permanently ON, on the RDC6445G diagnostics. And now I cannot jog the Y axis, which I assume is due to the limits staying on. I cannot get these to clear, even if I unplug the connectors from the main board. After installing all six switches, they worked fine but I seem to recall the Y axis lightly crashing in to one of the switches, and probably why they are now permanently on.
The switches are active low, just simple lever micro-switch type. I appreciate that I can disable them but I need the function. I also checked them with a meter, prior to adding them to the controller.
Having powered everything down this morning and booted up, the machine tries to do a home sequence but fails on the Y axis. I reconnected the Limit plugs and interestingly…although the diagnostics show the Y limits are ON, now when I press the switches, the (diagnostic) 'LED’s go out (as if they were active high). It didn’t do this yesterday, they just stayed on constantly. I’ll do a bit more investigation today.
I did wonder if a Reset to Factory Defaults would solve the issue but it asks for a password, and it’s not the usual RD8888. So, on a side note, do you know what this password is? I have not set any any other passwords. The manual isn’t the best at describing this function.
This is a new-build, and I’ve just got the mechanics side of things completed. I’m not too far in the build yet, so I didn’t have any saved settings to worry about (although I do now).
As you can tell, I’m pretty new to lasers, although familiar with CNC’s, having built a desktop milling machine and converted a couple of woodworking machines to touch-screen control using Mach3 and more recently UCCNC.
Thanks for the advice and I’m sure I’ll be posting more questions in the near future!
