Yes, I would suggest using crontab. Only thin to look for might be permissions but if the above works, go with it.

Re: Spindle PWM

and want to run my 110VDC spindle with this variable power supply: https://www.aliexpress.com/item/33007437798.html?spm=a2g0s.9042311.0.0.70584c4dutBK99 The line from the description that explains it is "Except the board inside a PWM speed control, can also support an external PWM signal input spee...

Re: Spindle PWM

I own a woodpecker CNC has PWM spindle control, and it outputs 0-24 VDC when I test it with a multimeter. I guess I was expecting the voltage to stay static, and the average current to fluctuate based on the duty cycle to control the power delivery to the motor. PWM, pulses the supplied voltage and...

Re: Use with ESPduino-32?

Also, do you get more funds if I buy from ebay or the Elecrow store on AliExpress? I get more funds from the Ebay store but only sell the boards in kit for to be assembled by the user. Is there any extra QC done for the boards in either store? Just visual inspections and that has been good.

Re: Use with ESPduino-32?

I figured I'd clip the 5v pin, and solder the 3.3v pin to it on top of the board, so that it runs on 3.3v. I know that the old-version knock-offs on AliExpress don't work with the ESPduino-32 unless I remove the resistor next to the end stop pins (sends it into a boot-loop). Is the new version of t...

Re: Homing with 2 motors on Y axis

RPI CNC Hat V2.51 and V2.60 has the same pin setup... So it should be possible to work... Saying that I would advise you to experiment with the stepper motors unhooked from the machine. Checking that the steppers run in the correct direction and that the end stops work as described by the setup above.

Re: Homing with 2 motors on Y axis

All axis/directions work fine in bCNC. It's only when I click on home in bCNC where I' having an issue, so far. I havent tried running any gcode yet. Super weird that only one stepper would work with homing when the signal are hardwired. Especially if the Y axis can move in both direction when in n...

How do you power the stepper drivers?
