Marlin not sending updates to Delta. I got my delta running and while trying to adjust settings in Marlin and then uploading, I get no change to the delta. It is uploading ok but I change X,Y or Z endstop offsets and they don't change anything when I retry home position on my delta. I have mechanical end-stops which I can adjust so not a biggy but it still doesn't make sense. Also I have a high spot ( 1.5mm) in the centre and I am trying to change the DELTA-ROD-OFFSET in Marlin to compensate for this but 160 to 250 makes no difference. I have some shortcut buttons in Pronterface set for X tower as X-77.94 Y-45 Z5 and then I just move down 5mm to check clearance with paper. https://reprap.org/forum/read.php?4,734085,734085#msg-734085 Sun, 13 Sep 2026 11:01:13 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?4,734085,734470#msg-734470 Re: Marlin not sending updates to Delta. https://reprap.org/forum/read.php?4,734085,734470#msg-734470
Turned out I had moved the delta settings up in Marlin Config.h to make it easier to adjust settings but I moved them too far up before the connection and baud rate settings so Marlin was ignoring them.

Move them below these lines and now all is good.]]> gregted Reprappers Sat, 31 Dec 2016 11:45:14 -0500 https://reprap.org/forum/read.php?4,734085,734186#msg-734186 Re: Marlin not sending updates to Delta. https://reprap.org/forum/read.php?4,734085,734186#msg-734186 stephenrc Reprappers Fri, 30 Dec 2016 14:31:45 -0500 https://reprap.org/forum/read.php?4,734085,734085#msg-734085 Marlin not sending updates to Delta. https://reprap.org/forum/read.php?4,734085,734085#msg-734085
