You could use the coolant pin to drive a cheap arduino relay and use this to switch a larger relay for the router.
The pwm output MAY give odd readings on a digital voltmeter as it gives “pulses” and as the dvm presents very little load the reading may not be accurate. Also it may give odd behaviour for controlling a relay ( not what it was designed to do).
I have been playing with the pwm output as a pwm is not always the best choice for controlling spindles/Lasers - and have found for reliable results a little electronics added on helps
I am having a problem where interference is tripping my endstop switches. Not sure why. But I just turn them off after I home and turn them on when I have to home again, and that seems to work.
Yesterday, I ran a 10 foot 5V cable from the controller box through all the drag chain, to the outside of my enclosure. I will let the switching (relay) of the 120v occur outside of the enclosure to minimize the EMF related errors. Relay arrives tomorrow…I’ll keep you posted as to it operation and concerns.
Haha. I won’t tell you why I bought because it’s (a) too small so I had to take my homing switch plug apart pin by pin. So painful, and (b) I see that carbide version is larger and each link opens so you don’t have to painfully snake each cable.
AIUI, the original SO3 design didn’t have drag chain — I added some spiral wrap to mine to protect the wiring and at the 16" x 16" size, w/ the electronics on the back of the X-axis extrusion, that seemed fine.
The XL and XXL both merit, and have drag chain standard. It’s a big upgrade, and the kinks are getting worked out of the kits and upgrades — managed to get mine together, but haven’t had occasion yet to put it to work, hopefully tonight or tomorrow.
Yeah, I plan on waiting for a while, I have projects that need to be done now, and would require a lot of time and energy to upgrade, and it is working right now fairly well.
William,
The Link to the schematic and board in Eagle format, bill of materials, and optimized Gcode, as found in this Spindle Control - WIKI, results in a FILE NOT FOUND.
and that is why I don’t like for folks to share stuff via drop box.
All I can think of to do is see if someone else who downloaded it kept a copy, or look back through the wiki edit history and see if you can contact the person who initially uploaded it.
When I’ve needed to store additional files beyond what the wiki allows I’ve cheated and added them as attachments to a .pdf and then uploaded the pdf.
Using Carbide Create and Carbide Motion, latest versions, the router turns on during the tool change cycle. Looking at the Gcode, the M3 command is on the line after M6, but it doesn’t wait for the ‘continue’ button to be pressed. As such, the router has to be turned off and back on manually, which seems wrong.
I’m sure there is an edit to the Gcode that can be done, but I’d rather avoid the extra step.
