Between cases, a stepper motor for autofeeding NHF is gradually adapted. Based on the results of the experiments, the need to use an additional gearbox was revealed. As a gearbox, it was decided to use gears from an angle grinder (grinder).

This time the experiment was quite successful. It is still not clear just what exactly to use as a pulse generator, since the generator from aliexpress does not work very stably and has several switches, which are not convenient to control.

Also, to connect the autofeed unit, you will need to prepare an “onboard” power supply system for it on the machine: the regular transformer is rather weak and gives significant drawdowns under load.
