It is quite possible it is to high, but it was good before I changed, and the change is not that immense. It is litterally exruding four times as much as needed, and that doesn't correspond to the difference in the two excruders.
I bought a used UM2 that I upgraded to a "+", and now put this Bondtech excruder on.
I confirm that I did.....nt do that. I updated the driver from their (Bondtech) site. That's what I thought I was supposed to do. Works best so far, except for the now obligatory and quite inexplainable 25% flow situation..
I was playing with Tinkerware the other week and liked it, except for when it made the machine go loco. I tried it today again, and it still did make it go loco, and I simply havent found the relevant numbers to put in for not to break of an axis, yet. Otherwise it is what I hope to get running on permanence soon enough. I want my UM2+ running almost 24/7 too. For reasons...
Yes, I can see a huge difference in the grip, pull and grinding actions of this superior piece of hardware! Really a good investment that will pay itself of in the long run in sawed filament and non-failed prints!
I did factory reset it quite a few times today. I don't even know what do do with that G-code file..
I did those same five steps. Alas, I must have displeased the god(s?) of electronics today. Tinkerware bugged for me to much, and I reinstalled and rebooted the machine completely.
Yeah, those problems are hardly problems at all! I can live with those if I can avoid grinding filament and stopping hour-long prints with this much better excruder. And yes, those solutions are complicated. To complicated for me, too!
Perhaps there is a memory to empty or some odd number somewhere? What is striking me while looking at this testprint I printed here and now, is that exactly 25% flow is needed. ie. Somewhere its "times 4" on the calculation on how much filament to excrude. does definitively not correspond to a mix-up with steps/mm. I can not for certain say its because of the Bondtech driver, or... Dum dum dum.... A ghost in the machine? A kid changing a setting in my Cura installation to mess with me?? It works so well otherwise!
Thanks for all the responses and helpful advice guys, much appriciated!
