Yeah, there may be some slack in terms (remember that it's a non-commercial project done by enthusiasts!).
I don't really know about middle unused AXIS switch position (and couldn't find an answer...

I'm pretty sure "neutral" here means "manual" sub-mode (some inconsistency in terms?), nether "external" nor "internal".

Hi Qtron,

Don't know, guess depends on the diameter, pitch, material etc. I see that most people are using 1000+ PPR so that may say something.


This "External, Internal, Manual" switch sets...

See some text of the PCB translated to English (attached).

So, as far as I understand, if your encoder outputs square wave signal you don't solder any circuits in that area of the PCB (no LM2903...

Hi Qtron,
Right, there is no diagram for the shield PCB specifically, but there is that diagram which shows how Mega is connected to external components (buttons, LEDs, resistors etc.) and from...

!_ELS_V7.jpg image in the firmware archive contains schematic which must be a 100% match with the shield PCB (not sure about the encoder part though). So you can match Arduino pins to the shield pins...

TBH I did not understand some parts of that text by myself. But lite version is definitely missing asynchronous feed.
As far as I understand it's much better to just use full version (better...

As Bruce said, RGI stands for "Manual Encoder" (well done Bruce!).



BTW I don't know proper English terms for 2 kind of feeds:
1) when carriage feed is tied to spindle rotation speed (like...

I think "without the shield" means without any IO pins connected.


I think post #548 talks about version 7a_lite - are you interested in Lite version? anyway, here it goes:

About flashing v7 & v7a_lite, from https://www.chipmaker.ru/topic/118083/?page=22 :



So I get that when switching between v7 and older versions you must detach the shield, flash different...

Hi Bruce, OK



I read somewhere that both of them work fine but Nikolai's may be better designed - I don't know details (one have to read through many pages for that knowledge).



There...

Hi guys,
I speak Russian and I *may* be able to help you with some language-specific issues (like talking to chipmaker.ru moderators or translating some parts of the spec etc.).
I'm not very deep...
