I’m having issues with my Carvey’s spindle not turning on. Sometimes restarting it or spinning the spindle gets it to work. Today I removed the lighting PCB and spindle wiring and measured the voltage I am getting 65.3v using gcode M3 S1200 (M5 to turn it off). However, the photo from here indicates it’s operation at 12-48v.
Can anyone confirm it’s supposed to be max 48v? Or any idea on what to do outside of replacing it?
I will have to check the voltage at the power supply tomorrow.
I’m using Easel. I did some additional tests. After sending the M3 command, I am able to get the spindle to spin by slightly touching the top chrome cover clockwise. Then if I turn it of with the M5 command, slightly turn it counter clockwise, and it wont turn on again after sending the M3 command.
I’m sure this is why Neil Asked those questions, but he took too long to see your reply, so I’ll jump in with my 2 cents
$132 is the setting the M3 S-Code should be sending in order to get full speed. IF the gcode command is only 10% (1,200 is only 10% of 12,000) than the spindle is only receiving 10% of the required voltage which is not enough power to get the spindle turning from a stand still…
Thanks Seth. I hope that’s it, but it’s a good chance it’s not. Those settings are from a week ago. I periodically save my setting on my grbl machines whenever I try something new. Plus I was sending gcode “M3 S12000” and it had that weird behavior.
I will go down to the basement before I head to work. Otherwise I won’t be able to focus.
@Neil, I measured 48.3v at the power supply, coming from the controller, and at the spindle. That 65.3v reading that I got last night was because my smaller multimeter battery was going. It had a little battery symbol this morning when I went to use it.
