I just finished my putting together xCarve and my SuperPid2 controller.
I use a Dewalt 611 (240v) with my Superpid2 - with control via PWM.
my test went great - cannot wait to get into some serious carving.
however, I need the xcarve to send a stop signal to Superpid2 using the RUN input on Superpid.
my problem is that the router continues to spin at 5k RPM when the PWM is zero or input voltage is 0v (i tried both PWM and 0-10 with resistor divider).
The superpid will no drive the router speed below 5k rpm as most router motors will stall with speeds less than 5K.
SuperPid2 has an signal input called RUN which is used to stop the motor; does XController have a pin out that allows me to use the RUN input on Superpid2.
You could use the “Coolant Enable” (A3) or “Mist Enable” (A4) output to drive a relay or transistor (would have to be careful of current draw if using a relay - you can tap +5v from inside the X-controller if necessary).
I know I have to watch the current draw of the coil but I was thinking of still using M3 and M5. I need to work on my higher Y end plates and new X beam first.
I connected Superpid RUN to MIST output from xcontroller - with no job running output was zero volts as expected.
Problem: Superpid RUN starts router with a zero volt signal, will need to invert the signal thru a small break out cct.
break out cct will need to be powered by Superpid because it would be too dangerous to power from xcontroller as input to Superpid RUN would then go low with power loss hence turning on the router…
if power is lost to the Superpid then the router will not operate.
I wonder if Superpid has option to invert the signal, it is after all a microcontroller reading an input signal.
will email Superpid for a response on that one.
What program are you using to control the X-carve (Easel, UGCS, PicSender, Chilipepper, etc.).
What version of grbl are you using?
You may not need the inverter circuit.
[Edit 11/28 21:30 USA East coast} There is a potential problem in your test case which I have e-mailed SuperPid about to find out if they handle a particular situation properly.
You can fix this with a pull-up resistor as mentioned above.
I agree doing the G-Codes in the reverse order to control the motor. But I am concerned about loss of power at the xController - going to zero volts will turn the router motor on as a side effect of losing power.
I will try out the pull up resistor idea on the Superpid side to ensure that loss of power on xcontroller has no effect.
Do you think you could run 120v output to IOTrelay then plug router into IOTrelay. Then I could just use standard PWM from xcontroller to turn on IOTrelay. Not sure how Super pid controls speed of router and if the throughput of the IOTrelay would block signal
I have gotten a response from SuperPid from my inquiry. They are looking into the issue that I raised, but there isn’t a final determination yet. When I know more I’ll post it here.
Did you use the PWM output from the x-controller to the PWM input of the Super PID?
Also did you guys find a solution for turning off the router after the job is done?
Thanks
