    So I decided I want to stability test my latest rework. Who cares if I can print a benchy or an iris box. I need to see if I can print for days. Am I that stable? So I found a need. Which is more space on my toolbox at work. And I designed a shelf. A big triangle that will sit on the lip on the edge of my box and give me 300mm of more space. 300x300mm, btw. So the triangle's dimensions are 300x200x300. Sliced with a 0.3mm layer height and just 20% infill this is a 100 hour print. I took this picture at the very start and just wanted to point out the importance of sticking that first layer..

    I am currently just past half way done with this print. 53 hours in without a single hiccup.. That is except for filament. This print is using an insane amount of filament. So far I have paused print to change spools 3 times or my part is 4 color, so far.. But look at the wall of this print. I am so happy with how this machine is performing right now. Stepper motors are warm and cool. Nothing getting hot even this far in..

    Well this print got this far before failure..

    There is no feeling bad about the failure as it is a simple calibration issue. I have the tmc 2209 drivers running in uart and the current on x,y, and z was set to 1000 which might be good or a lot for a single stepper but I have 2 on each axis. My stepper motors stayed cold for the days of printing and after the print got so heavy Y skipped steps when I paused the print to change filament. But this print made it 72 hours before failure..

    I am printing another piece and am over 30 hours into this print passing the 100 hour mark of print time on my new rework. No problems so far, but still calibrating. And Extremely happy so far..

    Oh it hurts. But it is what it is. So this printer prints awesome. I still have some dialing in to do but it has become clear to me at this time that I can not connect a tft AND the MMU2S at the same time. This has pushed me to find another mainboard with at least 2 sets of rx and tx pins. I have found that here: https://www.biqu.equipment/collectio...rts-for-i3-mk3 . So I have ordered it and when it arrives I must rework this printer yet again to accept this board so I can move forward with the multi material stuff. No worries on wasted parts, though. This SKR 1.4 Turbo board will go to Printalicious, the printer that made all the parts for this rework and also for the blue geeetech i3 rework. Printalicious will also receive a mag flexible bed.
