gr5 896 Posted July 12, 2016 in UM2+ defaut E STEP value What? Mine is 282: X80 Y80 Z200 E282 Possibly I messed with that value years ago but I don't think so. Share this post Link to post Share on other sites

ultiarjan 1,076 Posted July 12, 2016 in UM2+ defaut E STEP value I've got one on 564 + feeder with the old stepper motor ( so basically the same as @GR5 's ) Share this post Link to post Share on other sites
darkdvd 733 Posted July 12, 2016 in UM2+ defaut E STEP value Same for me now @ultiarjan but E @ 738 because 369 x 2 (282 is wrong in thinker firmware) Share this post Link to post Share on other sites

ultiarjan 1,076 Posted July 12, 2016 in UM2+ defaut E STEP value Same for me now @ultiarjan but E @ 738 because 369 x 2 (282 is wrong in thinker firmware) Ok, had to use google translate for that... did you get any confirmation from @tinkergnome that the 282 is indeed an error? I hardly used the machine after the upgrade and don't have the time now to do a lot .... Another thing, I saw you used a "orange wig" to compensate for the longer axis of the original feeder motor, it's not needed, just push the small gear further on the motor axis (I have it stick out 10 mm) there is room enough in the feeder housing... (my printed connector plate is 6 mm) Share this post Link to post Share on other sites
darkdvd 733 Posted July 12, 2016 in UM2+ defaut E STEP value I post an issue on github for @TinkerGnome : "according the value for UM2.1_jarjar (https://github.com/Ultimaker/UM2.1-Firmware/blob/UM2.1_JarJar/Marlin/Configuration.h) The default steps value for E is 369 (see configuration.h line 371) Tinker value use 282 causing under-extrusion using new UM2+ feeder" I print a longer version of the small gear : With this gear, I must have 8mm of gap Share this post Link to post Share on other sites
ultiarjan 1,076 Posted July 12, 2016 in UM2+ defaut E STEP value I don't really see the point? the original gear (nylon?) is probably more durable..... Share this post Link to post Share on other sites
ultiarjan 1,076 Posted July 12, 2016 in UM2+ defaut E STEP value hmmm now I dont get it anymore, just checked my other printer, with Tinker 16.03.1+ and the full upgrade, it's on 369. My 2th printer also has 16.03.1+ and was on 282 ... (manually doubled it for the old motor). How can the same @tinkergnome versions have different step values? Could it be because I used the original UM2+ firmware before on one printer? Share this post Link to post Share on other sites
neotko 1,354 Posted July 12, 2016 in UM2+ defaut E STEP value Afaik (on umo+) the settings values are stored on the flash rom. And only when you do a factory reset you get the firmware settings. 1 Share this post Link to post Share on other sites
ultiarjan 1,076 Posted July 12, 2016 in UM2+ defaut E STEP value Ah so maybe the original um2+ firmware forces a reset and the tinker does not... that could explain it. Share this post Link to post Share on other sites

tinkergnome 586 Posted July 13, 2016 in UM2+ defaut E STEP value How can the same @tinkergnome versions have different step values? Could it be because I used the original UM2+ firmware before on one printer? I use the same source files for all variants, that's the reason why the e-steps stay on the (wrong) value of 282 for upgraded printers. It's the first time that someone noticed this... I'll put it on the todo list for future releases. And yes: there's no (implicit) factory reset, if you already have installed any 'plus' firmware before (no matter, if the old or the new one is the standard or the tinker version). 1 Share this post Link to post Share on other sites

gr5 896 Posted July 13, 2016 in UM2+ defaut E STEP value This is strange. I don't get any underextrusion at 282 steps. This is an *old* UM2 from when it first came out years ago but it has tinkergnome firmware. I put the "plus" kit on my UM2 extended (which does not have tinker gnome and I don't know steps/mm on that machine). I also put the meduza 2x upgrade on my UM2 temporarily and increased steps to 282*2 (scroll to final photo here): http://gr5.org/med/ At the moment I have the "bond tech" feeder on my UM2 but that machine is in the basement for a few days (resting) and I don't want to check steps/mm for that setup at the moment.

darkdvd 733 Posted July 13, 2016 in UM2+ defaut E STEP value For an UM2 without the new geared feeder, the value is 282 For an UM2+ or an UM2 with the upgrade kit (geared feeder) with the Ultimaker firmware, the value is 369 (according the firmware source code) For an UM2+ or an UM2 with the upgrade kit (geared feeder) with the TINKER firmware, the value is 282 and this is not the good value : must be change to 369 1 Share this post Link to post Share on other sites
