A20 Firmware V2.0 Source Location

Post by appdev007 » Mon Aug 03, 2020 1:16 am

My A20 homes to -10 on the X axis, which causes it to crash into the rail when it goes all the way to the right, and I would like to fix this, but I cannot find the V2.0 (what it came loaded with) source anywhere.

The GitHub repo seems to be out of date. https://github.com/Geeetech3D/Prusa_I3_3Dprinter

The only link I can find with the V2.0 firmware in it is https://www.geeetech.com/download.html?download_id=32, but it only has a hex copy so I cannot adjust the config values.

Anyone have a link to the source for the V2.0 firmware for A20 without 3d touch probe?

Well, I can see from some other posts...

https://www.geeetech.com/forum/viewtopi ... 20&t=70131

that according to site admin William, the latest firmware source is knowingly being withheld from customers. If Geeetech isn't going to release the source, could they at least update the current hex file to not home to negative values (i.e. x=-18) and issue a new hex release? Then continue to do so for other issues customers report? I will have a hard time recommending Geeetech products if they aren't going to either address issues on behalf (updated hex) of customers or make it possible for the customers to address their own issues (release source).

Previous firmware versions are available on GitHub, it is really helpful to customers, so I don't understand why the latest versions are not being made available. After all, it is an opensource firmware that you are basing off of.

Hi, appdev007!
I don't understand this behaviour if geeetech too!
Especially when pinout of gt2560v4 is the same as gt2560v3.x.

I'm using marlin 2.x on my gt2560v4 in a10 for about 2 months, all is great. You should find vert's github rep, he has made a great job with start_here.h header file.

Thanks gopher. I'm really considering going with a non-stock firmware. I'm just lacking the time. I came across vert's repo and considered it, but again, didn't have time to figure out his config. When I finally have the time I'm thinking about merging the changes for print resume and such from the latest on the geeetech repo with current marlin. I guess just because I like to play around with stuff. I should probably figure out vert's stuff. lol
