An overview of the drive modification that I did on my Inca 550 J/P
The drive is mounted underneath the table and uses a 3Nm Nema 23 stepper motor that was purchased on Amazon. The stepper drives a 10 tooth sprocket from McMaster (also a good source for the 05B metric drive chain). The motor and driver are powered by a meanwell 48V power supply.
Although the motor and driver are supposedly rated for 4.2 Amps, I am underdriving the motor under the assumption that the imported motor may not survive long at peak current. So far torque has been fantastic, and the motor and driver run at a reasonable temperature.
Variable drive speed is accomplished by an Arduino pro micro, because that’s what I had laying around. The Arduino sense the position of a potentiometer and then uses the map function to convert the returned value into a frequency for the tone function. I calculated the upper and lower frequencies so that I could vary between 5 and 20 feet per minute feed rate.
I honestly think steppers are a more affordable alternative to the normal bodine gearmotor modification that people do. If this motor wears out, I can buy a new one for .
Thanks for watching!

I used a Meanwell 48V but availability of buck converters for the Arduino are more limited. I believe driving with 36 V should also work well.

Inca 510 jointer/planer. I finally received the in-feed knob for adjusting the table height. Calling it good for now. Hoping to make a new stand and dust shoots for it. Need to use it for now.
