Instead of hacking marlin, why don't you set up a gcode sub-driver in Open PnP that is just a simple sketch that listens for your custom Mnn commands, then fires out feed instructions over RS485? Then you have an extensible setup that anyone can use - even with Smoothieboard, etc... I've just done my first production runs on my custom Open PnP machine. :D

I second that, that exactly what I have done for my custom future PNP: RS485 with named feeder + Custom driver in openpnp. Except the "on the shelf" part, I don't understand the point to use CNC motors control board (synchronized motor steppings which is not mandatory for a PNP) with the gcode constraints for a PNP.

Hey I had a thought! If that switch is wired as normally open and it fails then the motor will continue to spin forever, causing a tangled mess :) I think just reconnecting it as NC and inverting the logic in code will be marginally more reliable? (Like how you would for limit switches). Love the videos, keep it going man!

Awesome job Stephen! But PLEASE, do your mental sanity a favor and use CAN! RS485 is total crap, you'll have to spend countless hours making it work. With CAN, everything is handled by hardware (collisions, addressing, priorities....). CAN looks PERFECT for this purpose. I'd move back to a STM32F103 that is still super cheap but has CAN. Good luck! :)

Also I noticed no solder mask between your IC pads. This will burn you when you start reflowing QFNs and smaller parts but is totally fixable... Use gerbview to preview the solder mask exactly as it will be sent to pcbway in your gerbers. Then in pcbnew, under Board Setup then Solder Mask/Paste, set solder mask clearance and minimum width to 0.05mm. Not sure what the minimum is with pcbway, but I know this works with JLCPCB, and gives me solder mask between 0.5mm QFN pads.
@lawrencemanning
4 жыл бұрын
Interesting tip. My last board used 0.5mm pitch QFP parts and had no mask. I did a bit of research, looked at some existing boards etc. No mask between pins appeared normal so I just went with it and had no issues. Isn't lifting up the mask a risk, too, as it's going to be pretty thin. I used drag soldering for my install but I'm pretty sure reflowing would work, if a stencil was used.
@kevswims

I agree with this comment. Even on very fine pitch components there should be mask between the pads. It greatly reduces the chance of shorts if things are not perfectly aligned during solder printing and part placement.

Whats the reasoning behind them?
