ensure your maximum carriage travel is greater than your homed height
-
I don’t quite understand how they’re different. The homed position should be at the maximum carriage, where the end stops are shouldn’t it? Or an I misunderstanding
-
@ZPomeroy concider what happens if you move to z0 and x0,y0 - then you move to x100. One of the carriages will have to move further down than the possition it had at z0, x0, y0 - thereofre the carriage travel has to be longer than the usable z height (this got me the first time with a delta on RRF as well)
-
So if the height of the nozzle above the bed when all three carriages are just high enough to trigger the endstop switches (ie Homed height) is 428.84 How do I figure out what the carriage travel is? I'm so sorry if I'm being irritating, its all so overwhelming, I still don't quite understand the difference and how to measure that from the homed height
-
I'm sure you could calculate it with some trig functions, but I just measured the difference between z0x0y0 and the lowest carriage after manually moving the effector around the build plate and added a few mm for measure. You may want to wait for someone who knows that they're talking about to come up with a more scientific approact.

I gave the config tool a go, trying to carefully move the settings over. I failed miserably. Is it possible to put RRF2 onto the board and use the current config files I have?
-
If you have a working M665 and M666 line from RRF2 then it should work the same with RRF3 afaik, moving back to RRF2 (which is perfectly possible with the same procedure as upgrading) will not change how the printer responds to those two lines. (?)
edit: hmm, can't seem to find the relevant docs, nor have access to the machine for a while. back to jay_s_uk perhaps?
-
I put in all the details perfectly for the config tool, and it didn't make anything work properly, so I'd prefer to go back to RRF2 than to keep messing with RRF3, because as you can see its all over my head, and I can't diagnose the issue of something I can't understand. So I'd just prefer to use the config I was given from the previous owner, and as far as I know the way to do that is to erase and reset the board, and install RRF2, and then upload the config I was given. Does that sound right?

just upload something like the 2.05 release .zip and let the board deal with it. (and then upgrade to 2.05.1)
-
Can I do that through the DWC?
-
sure
https://duet3d.dozuki.com/Wiki/Installing_and_Updating_Firmware#Section_Usual_procedure (it says to upload .bin files, but will accept the whole thing as .zip file as well. so fetch this and upload as described)
-
I tried to get the software to go back, I wasn’t able to, and I’ve stuffed up all the files that should be on the SD card. I’ve put RRF3 back onto the board and can connect through S3D but not through the DWC, it won’t connect, it says something is wrong with the www files. Could someone tell me what is supposed to be on the SD card so I can connect to the board online?

but you'd want to get https://github.com/Duet3D/RepRapFirmware/releases/download/3.1.1/DuetWebControl-SD-3.1.1.zip to put in the /www folder and not the file linked to in the wiki which is a bit dated for RRF3.
