Thanks. Seems like it used to be fine, but for some reason became "off". I "fixed" it by using offsets, and reducing bed size a little.

Hey @dthurbon We do not have a problem with anyone reviving an old thread here, we welcome everyone and want to know their opinions. I am sorry that the machine was essentially DoA but hopefully some manufacturers were able to take note and possibly improve on the short comings of printers like this one. Let us know if you have any more thoughts on the matter!

So if the paper drag method isnt a good idea on robos do you have a better method to "true" the z level? Beyond starting a print and when you see a smush you pause and turn the z rods to the left then resume or when you see squiggley lines you pause and turn the z rods to the right? Ive heard to do a z home all then turn the machine off and do the paper drag or feeler guage...
