port of your schematic

[linewallker]

Hello, Some time ago I was trying to find ESP 32 CNC shield to buy and I found your schematic on the GITHUB so I downloaded your schematic and made some changes in it for my personal purposes.

Can I ask you for checking my schematic if it will be compatibile with your firmware ?

Thank you for any kind of answer.

Sorry, I was on vacation when this message arrived. Please ask this question on our public channels of our Discord server. Please post a PDF of the schematic and describe the changes you made. Also post a PDF of the layout.

Hello, I have added Esp32_shield.pdf into repository with schematics.

Basicly I have made only small changes in one of your designs.

I have removed SD card because I am using big laser engraver 120 cm x 135 cm for photo engarving in full size and it makes files bigger than 2 gb so it is better to stream from PC.

I have cloned X and Y sockets for drivers, but not for independt driving of each motor, only created another socket with same connection as old one.

I have added pinout for external rellay, I have conected to EN circuit to take out signal for turn On and Off the rellay when the mottors are running, using for Air Assist compressor for 220V, I have already tested this connection on Arduino CNC shield connected to EN pin on unused Z axis and it is working fine with ferite filter on wiring to the rellay from shield.

Also I have alternated the connections on PCB but strictly kept your pinouts.

I hope this description is Ok for you :)
