NanoELS separate box for control panel, Pictures

[wberggren]

First of all many thanks to Maxim for his excellent work and very good description. I have an Optimum lathe which has a smaller diameter spindle. This forced me to select a larger gear wheel (100 teeth) for the encoder. The encoder that I had was a 1024 pulses Omron 26B2 encoder from ebay. The speed can be easily corrected in the software. I also used a servo stepper motor which works fine. Here are the pictures:

Such an awesome build, thanks for sharing! Very well done.

What setting needs to be modified, if any, if you are using a larger gear for the encoder? I'm using a v-belt drive because I couldn't squeeze the gear behind the pulleys, so I'm no longer at a 1:1 ratio. However, I didn't see a setting in the code to modify.

@RGUERI1 calculate the number of pulses encoder sends per revolution of the spindle and use it in ENCODER_STEPS if you're building H2 - https://github.com/kachurovskiy/nanoels/blob/main/h2/h2.ino#L6 - cheers!

Thanks for speedy reply. I have the Nano 4 but I saw that parameter in the ino file. Assume it’s the same function? Thanks, Rustin Get Outlook for iOS<https://aka.ms/o0ukef>

Yes, it's same parameter in the same line - https://github.com/kachurovskiy/nanoels/blob/main/h4/h4.ino#L6 - thanks!

Ok, my encoder pulley is smaller than the spindle pulley that I'm using. I come up with 1.644 turns of the encoder for every 1-turn of the spindle. If my math is correct that is 986.664 pulses per spindle rev. Does that make sense?

Perhaps we should take this to a new discussion and keep this thread dedicated to the H2 build above. Sadly fractional PPR is not supported, we rely on it being convertible to integer pretty hard.

Oops, I thought this was just an email between us! . So in summary it needs to come out to a whole number to work correctly? Get Outlook for iOS<https://aka.ms/o0ukef>
