HI all,

I am just in the final stages of completing the focuser and I LOVE it, it
works great sitting on the bench with firmware 330, which is what I had when
I started this project. I am using the DRV8825HW203 board with RE and the RE
works great with the 330 FW but doesn't with 336. When connected to the
WIN10 program ver. 2.5.1.3 the motor moves with both version 330 and 336,
it's the RE that doesn't work with 336. I have checked the config file and
RE is enabled. I could probably figure it out after many hours of pouring
over the code but maybe someone else has seen this problem. I guess I also
don't have to have the latest firmware, 330 is working fine.

Your thoughts?

Cheers

Paul

Hi Robert,

Sorry to report, it behaves the same as 336, no RE function. I have gone back to 330 for now as it works fine for my application.

Thank you for your effort.

Hi Robert,
have the sane problem with RE in 336.
First check with the 337, the RE works!

Hi Robert,

The last FW you posted 337a works like a charm, I have RE working and temp probe works now as well. I 3D printed a case and have the 1.3" OLED working. I'll post pics shortly.

Thank you again, looking forward to getting under the stars in a few days.

Cheers

Paul
