Is it normal for the extruder stepper motor be too hot to touch? Seems like there should be a thermal break of some sort between the extruder heater and the stepper.
Tks, Roger

All motors but Z are being ran at max Vref (118 not the normal 128 one would believe) so they get hot enough to blister your hand as X did to me. Since the carriage is ABS I am surprised the motors haven't caused it to sag at the very least.
It appears not a soul knows what Vref should really be except it should not be at full throttle (at least with Marlin using Stepsticks we knew what Vref meant precisely).
My suggestion would be to turn all motors down to 80 (leave Z at 40) and do a nice print and see what happens. If no skipping then after 1 hour feel the motors and if mildly warm 80 was the magic number.
You can do what I did with my I3 and just keep going lower and lower until the motor would skip or lose steps then back it up some. By doing that you will have way cooler motors that will last longer and the ABS plastic parts will love you for it. So, 80 and if that works go 60 and if not then 70, etc... since we have no idea wth the formula is for a Mightyboard.

Finally cleared the clogged with a nail. Just heated it up with a bic ligter and jammed it through. Took 2 attempts to finally dislodge the clog.
As for the right extruder that refused to unload the filament, I just cut it off and let it feed through. Had to unload it so I can make room for the nail to go through the clog at a straight angle.
I removed my dispute with aliexpress. Printer seems to be working fine now.
Except, it still can't print my knee replacement as good as makerbot.

Yeah I think they should offer 10mm upgrade as a package. Your case is one of the obvious downsides to incremental updates. But the alternative would be bundling all these incremental improvements into a new printer version which we would all have to wait for rather than getting them upfront.
I think the current incremental model makes sense if they're trying to lead in price/performance. I just hope they make these upgrades available to owners as they've done with their main boards.
They countered my $630 auction offer with $650 citing that they'd sold out of stock in their warehouse. It didnt make too much sense to me at the time hut it does now. Hopefully this means you get the latest from eBay. Not sure about Amazon. Worst case just ask before buying.

Has anyone used a Kossel delta-style printer?
Just found file from dude that designed the thing with all the parts. I sure would like to try and build one if its a worthwhile printer...they look kinda cool.
Printer will print perfect...
