I need to build a similar repetier host
Hi I'm trying to make my school project. I am trying to make a similar Repetier Host, Firstly I've started to learn repetier protocol,
https://github.com/repetier/Repetier-Firmware/blob/master/repetier communication protocol.txt
I checked this link
I didn't fully understand for example, this part: Comparison of sizes: L1 Command 1: L2 G1 E10810.1 F1000 L3 Original size: 21 Bytes L4 Updated for errorcheck: L5 N6654 G1 E10810.1 F1000 *65 L6 Errorcheck size: 29 Bytes L7 repetier-protocol: 15 Bytes I couldn't understand how the orginal size is 21 bytes in L3 and what is *65 means, I guess it's comes from fletcers checksum but I'm not sure. What does exactly mean of this ?
