I've got a CNC machine and I recently started using a spindle for it. At first it was running smoothly with no issues, but after the first brush pair wore off (I've replaced them later on) it started interfering with the Arduino/gshield and pc monitor. The monitor displays a "no signal" message, although after turning off the spindle or turning it to a low speed the signal comes back. The other problem is that after running a long job, sometimes the gshield disconnects and the job stops midway.
- What part could be causing all this interference?
- How can I shield that part so it stops interfering with other electronics?
I am using the following hardware:
- 600 watt spindle
- 600 watt power supply with variable speed
- the wires from the spindle to the power supply are not shielded, although Ive tried covering them with aluminium foil, not sure if that should be of any benefit, I've read it somewhere so I gave it a try.
- Gshield with Arduino, connected to a Raspberry pi.
All the electronics are within 70 cm radius.
