configuring smoothie firmware Hello, I have built a rotary delta printer and need to use smoothie firmware to run it. ( I believe it is only smoothie that has this firmware type) but have come up against a problem. The firmware loads fine and I can move the arms on all three axis as they should move, but when I attempt to home the printer it just cuts out and a box pops up to say it is an " illegal move" and to reset the printer or send M999. Could anybody give me a clue as to what the problem might be, Thanks https://reprap.org/forum/read.php?418,880810,880810#msg-880810 Mon, 11 May 2026 17:20:08 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?418,880810,881076#msg-881076 Re: configuring smoothie firmware https://reprap.org/forum/read.php?418,880810,881076#msg-881076 catmandu Smoothie Sat, 30 Jan 2021 09:56:52 -0500 https://reprap.org/forum/read.php?418,880810,880976#msg-880976 Re: configuring smoothie firmware https://reprap.org/forum/read.php?418,880810,880976#msg-880976

I have been on this project for some time now and , if I remember correctly the RepRap firmware is limited in its sizing (using a calibration tool similar to repetiers) and so was not suitable

I can't think where you got that idea from. The size limits in RRF are of the order of kilometres, and always have been.

BTW did you do a search to see if anyone has done a Smootheware fork that supports Rotary Delta?]]> dc42 Smoothie Thu, 28 Jan 2021 02:33:20 -0500 https://reprap.org/forum/read.php?418,880810,880968#msg-880968 Re: configuring smoothie firmware https://reprap.org/forum/read.php?418,880810,880968#msg-880968 With regards to marlin, again I am having a couple of problems with compiling it using PlatformIO. It has been so long since I have needed to alter marlin that I think I have forgotten something. I use SKR V1.3/4 boards on all my printers and I decided a few weeks back to update marlin to the latest 2.0.7. and change the drivers on a delta from LV8825 to TMC2100. Although the firmware compiled and uploaded successfully it would not connect with Pronterface or Repetier although firmware.bin changed to FIRMWARE.CUR, and when I checked back on PlatformIO I find that the file is only 56kb when I am sure that the last one was about 500kb, and rerunning the compilation I notice in the terminal window that there is a section that is "searching for dependencies" but is followed by "no dependencies found" which I think is wrong and would explain why the build time is about 50 seconds when I am sure that it used to be about 300. I would be grateful for any light shed on this]]> catmandu Smoothie Wed, 27 Jan 2021 11:53:17 -0500 https://reprap.org/forum/read.php?418,880810,880823#msg-880823 Re: configuring smoothie firmware https://reprap.org/forum/read.php?418,880810,880823#msg-880823 dc42 Smoothie Fri, 22 Jan 2021 13:27:52 -0500 https://reprap.org/forum/read.php?418,880810,880810#msg-880810 configuring smoothie firmware https://reprap.org/forum/read.php?418,880810,880810#msg-880810 I have built a rotary delta printer and need to use smoothie firmware to run it.
