In trying to get my TAZ back to printing the way it was when I got it, I’ve been following calibration guides and such to make sure it’s spot on. The calibration on this thing is nailed as far as I can tell.
However…
I’ve run the octopus.gcode file a few times and I’ve noticed that it appears that there’s something going on that results in offset tool paths.
It looks like you are skipping steps. The speed settings in Repetier-Host may be too high, switch to Pronterface to test. What speeds are you using in Slic3r, what speeds in RH?
the host software (repetier or pronterface) does not limit the speed when the machine is run from G-code…The firmware is all that limits it when it gets a G-code command. You can easily prove this by typing in the command “G1 X200 F50000” or similar, and even if the host software is set to only go at 5mm/min, the machine will still run as fast as the g-code commanded it to (or it will try at least).
I would also double check your pulleys aren’t moving, you want one of the set screws to be tightened all the way against the flat part of the shaft on the stepper motor for both x and y
