Dispensing robot CNC conversion

So start and pause from the unit, or even a foot switch, as well as zero chance of serial data issues is worth $200 for me.

You can do it with the $30 board as well (the most famous MKS DLC32 board features multiple I/O signals that can be wired to buttons and an SD card slot for offline use) But the Ruida is offering more functionality, I guess. I have no experience using those.

@MikeLaser

When you say the pwm signal will vary, it will only vary between the min and max of the lightburn layer, if both are set to the same value there should be a constant output.

What I meant is that the amount of glue will vary with the length of the shape (but this might be desirable, as you said). What I had in mind was more like dispensing defined drops of glue that always have the same amount of glue, no matter if the shape differs. That’s more simple but less flexible, I think.

There will be a lot of trial and error getting each file perfect, so i was hoping not to have to do custom code. So while pwm for a stepper might not be ideal, there may be a tradeoff to how easily i can adjust that output and test using lightburn without any customizations.

That’s why I mentioned the z-axis function. This already drives a stepper at a defined amount, so you can start right away without thinking about the PWM to stepper conversion

I misused this function as well to integrate a turn table to a diode laser, see my post here: DIY laser turn table Imagine each turn of the disc is a glue dispersion operation of a defined amount.
