MendelMax Build: Part II
The beast is alive. Electronics showed and all sorts of other bits and bobs showed up last week and we’ve been squeezing in a couple late nights to get the mendelmax up and running. You can see from the photo that the coffee pot was an integral part of the process. We’ve got a heated pcb for the build platform but at the moment we’re going to get calibrated printing PLA so we don’t need a heat bed yet.
First calibration cubes off the printer show impressively tight clean layers for a first go and also illustrate that PLA needs a fan for cooling, otherwise you get the drooping and sagging that you can see halfway up the prints.
Looks good! FYI if you increase the wall thickness of your parts you might get a more consistent surface. Depending on what your print resolution is you might need to bump up to 0.04″ minimum, or try 0.03″
I’m at 0.3 at the moment, but it looks like I may need to tweak the y-axis jerk settings in my marlin firmware. After re-aligning all my axis I was able to isolate most of the layer misalignment to my y, and its an issue that other people are having in the google groups. Haven’t had a chance to see if this is the solution as the mendelmax is hibernating until we launch our imminent kickstarter.
